-- Glide can be installed either via homebrew: `$ brew install glide` or via the official glide script: `$ curl https://glide.sh/get | sh`
-- The glide plugin `glide-vc` must be installed from source: `go get github.com/sgotti/glide-vc`
+If you happen to update the provider templates (in `/templates`), you need to run `go generate` to update the `autogen` package.
 
-If you want to add a dependency, use `$ glide get` to have glide put it into the vendor folder and update the glide manifest/lock files (`glide.yaml` and `glide.lock`, respectively). A following `glide-vc` run should be triggered to trim down the size of the vendor folder. The final result must be committed into VCS.
+### Setting up dependency management
 
-Care must be taken to choose the right arguments to `glide` when dealing with dependencies, or otherwise risk ending up with a broken build. For that reason, the helper script `script/glide.sh` encapsulates the gory details and conveniently calls `glide-vc` as well. Call it without parameters for basic usage instructions.

+
+And go to [http://127.0.0.1:8000](http://127.0.0.1:8000).

+Traefik integrates with your existing infrastructure components ([Docker](https://www.docker.com/), [Swarm mode](https://docs.docker.com/engine/swarm/), [Kubernetes](https://kubernetes.io), [Marathon](https://mesosphere.github.io/marathon/), [Consul](https://www.consul.io/), [Etcd](https://coreos.com/etcd/), [Rancher](https://rancher.com), [Amazon ECS](https://aws.amazon.com/ecs), ...) and configures itself automatically and dynamically.
+Pointing Traefik at your orchestrator should be the _only_ configuration step you need.

 ## Overview
 
-Imagine that you have deployed a bunch of microservices on your infrastructure. You probably used a service registry (like etcd or consul) and/or an orchestrator (swarm, Mesos/Marathon) to manage all these services.
-If you want your users to access some of your microservices from the Internet, you will have to use a reverse proxy and configure it using virtual hosts or prefix paths:
+Imagine that you have deployed a bunch of microservices with the help of an orchestrator (like Swarm or Kubernetes) or a service registry (like etcd or consul).
+Now you want users to access these microservices, and you need a reverse proxy.
 
-- domain `api.domain.com` will point the microservice `api` in your private network
-- path `domain.com/web` will point the microservice `web` in your private network
-- domain `backoffice.domain.com` will point the microservices `backoffice` in your private network, load-balancing between your multiple instances
+Traditional reverse-proxies require that you configure _each_ route that will connect paths and subdomains to _each_ microservice. 
+In an environment where you add, remove, kill, upgrade, or scale your services _many_ times a day, the task of keeping the routes up to date becomes tedious. 
 
-But a microservices architecture is dynamic... Services are added, removed, killed or upgraded often, eventually several times a day.
+**This is when Traefik can help you!**
 
-Traditional reverse-proxies are not natively dynamic. You can't change their configuration and hot-reload easily.
+Traefik listens to your service registry/orchestrator API and instantly generates the routes so your microservices are connected to the outside world -- without further intervention from your part. 
 
-Here enters Træfik.
+**Run Traefik and let it do the work for you!** 
+_(But if you'd rather configure some of your routes manually, Traefik supports that too!)_
 
 ![Architecture](docs/img/architecture.png)
 
-Træfik can listen to your service registry/orchestrator API, and knows each time a microservice is added, removed, killed or upgraded, and can generate its configuration automatically.
-Routes to your services will be created instantly.
-
-Run it and forget it!

 ### Backends
 
 A backend is responsible to load-balance the traffic coming from one or more frontends to a set of http servers.
+
+#### Servers
+
+Servers are simply defined using a `url`. You can also apply a custom `weight` to each server (this will be used by load-balancing).
+
+!!! note
+    Paths in `url` are ignored. Use `Modifier` to specify paths instead.

+    url = "h2c://172.17.0.6:80"
+    weight = 1
+```
+
+- Two backends are defined: `backend1` and `backend2`
+- `backend1` will forward the traffic to two servers: `172.17.0.2:80` with weight `10` and `172.17.0.3:80` with weight `1`.
+- `backend2` will forward the traffic to two servers: `172.17.0.4:443` with weight `1` and `172.17.0.5:443` with weight `2` both using TLS.
+- `backend3` will forward the traffic to: `172.17.0.6:80` with weight `1` using HTTP2 without TLS.
+
+#### Load-balancing
+
 Various methods of load-balancing are supported:
 
-- `wrr`: Weighted Round Robin
-- `drr`: Dynamic Round Robin: increases weights on servers that perform better than others. It also rolls back to original weights if the servers have changed.

+### Why ?
+
+In order to help us learn more about how Traefik is being used and improve it, we collect anonymous usage statistics from running instances.
+Those data help us prioritize our developments and focus on what's more important (for example, which configuration backend is used and which is not used).
+
+### What ?
+
+Once a day (the first call begins 10 minutes after the start of Traefik), we collect:
+
+- the Traefik version
+- a hash of the configuration
+- an **anonymous version** of the static configuration:
+    - token, user name, password, URL, IP, domain, email, etc, are removed
+
+!!! note
+    We do not collect the dynamic configuration (frontends & backends).

+
+### `caServer`
+
+The CA server to use.
+
+This example shows the usage of Let's Encrypt's staging server:
+
+```toml
+[acme]
+# ...
+caServer = "https://acme-staging-v02.api.letsencrypt.org/directory"
+# ...
+```
+
+### ACME Challenge
+
+#### `tlsChallenge`
+
+Use the `TLS-ALPN-01` challenge to generate and renew ACME certificates by provisioning a TLS certificate.
+
+```toml
+[acme]
+# ...
+entryPoint = "https"
+[acme.tlsChallenge]
+```
+
+!!! note
+    If the `TLS-ALPN-01` challenge is used, `acme.entryPoint` has to be reachable by Let's Encrypt through port 443.
+    This is a Let's Encrypt limitation as described on the [community forum](https://community.letsencrypt.org/t/support-for-ports-other-than-80-and-443/3419/72).
+
+#### `httpChallenge`
+
+Use the `HTTP-01` challenge to generate and renew ACME certificates by provisioning a HTTP resource under a well-known URI.
+
+Redirection is fully compatible with the `HTTP-01` challenge.
+
+```toml
+[acme]
+# ...
+entryPoint = "https"
+[acme.httpChallenge]
+  entryPoint = "http"
+```
+
+!!! note
+    If the `HTTP-01` challenge is used, `acme.httpChallenge.entryPoint` has to be defined and reachable by Let's Encrypt through port 80.
+    This is a Let's Encrypt limitation as described on the [community forum](https://community.letsencrypt.org/t/support-for-ports-other-than-80-and-443/3419/72).
+
+##### `entryPoint`
+
+Specify the entryPoint to use during the challenges.
+
+```toml
+defaultEntryPoints = ["http", "https"]
+
+[entryPoints]
+  [entryPoints.http]
+  address = ":80"
+  [entryPoints.https]
+  address = ":443"
+    [entryPoints.https.tls]
+# ...
+
+[acme]
+  # ...
+  entryPoint = "https"
+  [acme.httpChallenge]
+    entryPoint = "http"
+```
+
+!!! note
+    `acme.httpChallenge.entryPoint` has to be reachable through port 80. It's a Let's Encrypt limitation as described on the [community forum](https://community.letsencrypt.org/t/support-for-ports-other-than-80-and-443/3419/72).
+
+#### `dnsChallenge`
+
+Use the `DNS-01` challenge to generate and renew ACME certificates by provisioning a DNS record.
+
+```toml
+[acme]
+# ...
+[acme.dnsChallenge]
+  provider = "digitalocean"
+  delayBeforeCheck = 0
+# ...
+```
+
+##### `delayBeforeCheck`
+
+By default, the `provider` will verify the TXT DNS challenge record before letting ACME verify.
+If `delayBeforeCheck` is greater than zero, this check is delayed for the configured duration in seconds.
+
+Useful if internal networks block external DNS queries.
+
+!!! note
+    A `provider` is mandatory.
+
+##### `provider`
+
+Here is a list of supported `provider`s, that can automate the DNS verification, along with the required environment variables and their [wildcard & root domain support](/configuration/acme/#wildcard-domains) for each.
+Do not hesitate to complete it.
+Every lego environment variable can be overridden by their respective `_FILE` counterpart, which should have a filepath to a file that contains the secret as its value.
+For example, `CF_API_EMAIL_FILE=/run/secrets/traefik_cf-api-email` could be used to provide a Cloudflare API email address as a Docker secret named `traefik_cf-api-email`.

+
+#### `resolvers`
+
+Use custom DNS servers to resolve the FQDN authority.
+
+```toml
+[acme]
+# ...
+[acme.dnsChallenge]
+  # ...
+  resolvers = ["1.1.1.1:53", "8.8.8.8:53"]
+```
+
+### `domains`
+
+You can provide SANs (alternative domains) to each main domain.
+All domains must have A/AAAA records pointing to Traefik.
+Each domain & SAN will lead to a certificate request.
+
+!!! note
+    The certificates for the domains listed in `acme.domains` are negotiated at traefik startup only.
+
+```toml
+[acme]
+# ...
+[[acme.domains]]
+  main = "local1.com"
+  sans = ["test1.local1.com", "test2.local1.com"]
+[[acme.domains]]
+  main = "local2.com"
+[[acme.domains]]
+  main = "*.local3.com"
+  sans = ["local3.com", "test1.test1.local3.com"]
+# ...
+```
+
+!!! warning
+    Take note that Let's Encrypt applies [rate limiting](https://letsencrypt.org/docs/rate-limits).
+
+!!! note
+    Wildcard certificates can only be verified through a `DNS-01` challenge.
+
+#### Wildcard Domains
+
+[ACME V2](https://community.letsencrypt.org/t/acme-v2-and-wildcard-certificate-support-is-live/55579) allows wildcard certificate support.
+As described in [Let's Encrypt's post](https://community.letsencrypt.org/t/staging-endpoint-for-acme-v2/49605) wildcard certificates can only be generated through a [`DNS-01` challenge](/configuration/acme/#dnschallenge).
+
+```toml
+[acme]
+# ...
+[[acme.domains]]
+  main = "*.local1.com"
+  sans = ["local1.com"]
+# ...
+```
+
+It is not possible to request a double wildcard certificate for a domain (for example `*.*.local.com`).
+Most likely the root domain should receive a certificate too, so it needs to be specified as SAN and 2 `DNS-01` challenges are executed.
+In this case the generated DNS TXT record for both domains is the same.
+Even though this behaviour is [DNS RFC](https://community.letsencrypt.org/t/wildcard-issuance-two-txt-records-for-the-same-name/54528/2) compliant, it can lead to problems as all DNS providers keep DNS records cached for a certain time (TTL) and this TTL can be superior to the challenge timeout making the `DNS-01` challenge fail.
+The Traefik ACME client library [LEGO](https://github.com/go-acme/lego) supports some but not all DNS providers to work around this issue.
+The [`provider` table](/configuration/acme/#provider) indicates if they allow generating certificates for a wildcard domain and its root domain.
+
+### `onDemand` (Deprecated)
+
+!!! danger "DEPRECATED"
+    This option is deprecated.
+
+```toml
+[acme]
+# ...
+onDemand = true
+# ...
+```
+
+Enable on demand certificate generation.
+
+This will request certificates from Let's Encrypt during the first TLS handshake for host names that do not yet have certificates.
+
+!!! warning
+    TLS handshakes are slow when requesting a host name certificate for the first time. This can lead to DoS attacks!
+
+!!! warning
+    Take note that Let's Encrypt applies [rate limiting](https://letsencrypt.org/docs/rate-limits).
+
+### `onHostRule`
+
+```toml
+[acme]
+# ...
+onHostRule = true
+# ...
+```
+
+Enable certificate generation on frontend `Host` rules (for frontends wired to the `acme.entryPoint`).
+
+This will request a certificate from Let's Encrypt for each frontend with a Host rule.
+
+For example, the rule `Host:test1.traefik.io,test2.traefik.io` will request a certificate with main domain `test1.traefik.io` and SAN `test2.traefik.io`.
+
+!!! warning
+    `onHostRule` option can not be used to generate wildcard certificates.
+    Refer to [wildcard generation](/configuration/acme/#wildcard-domains) for further information.
+
+### `storage`
+
+The `storage` option sets the location where your ACME certificates are saved to.
+
+```toml
+[acme]
+# ...
+storage = "acme.json"
+# ...
+```
+
+The value can refer to two kinds of storage:
+
+- a JSON file
+- a KV store entry
+
+!!! danger "DEPRECATED"
+    `storage` replaces `storageFile` which is deprecated.
+
+!!! note
+    During migration to a KV store use both `storageFile` and `storage` to migrate ACME certificates too. See [`storeconfig` subcommand](/user-guide/kv-config/#store-configuration-in-key-value-store) for further information.
+
+#### As a File
+
+ACME certificates can be stored in a JSON file that needs to have file mode `600`.
+
+In Docker you can either mount the JSON file or the folder containing it:
+
+```bash
+docker run -v "/my/host/acme.json:acme.json" traefik
+```
+```bash
+docker run -v "/my/host/acme:/etc/traefik/acme" traefik
+```
+
+!!! warning
+    This file cannot be shared across multiple instances of Traefik at the same time. Please use a [KV Store entry](/configuration/acme/#as-a-key-value-store-entry) instead.
+
+#### As a Key Value Store Entry
+
+ACME certificates can be stored in a KV Store entry. This kind of storage is **mandatory in cluster mode**.
+
+```toml
+storage = "traefik/acme/account"
+```
+
+Because KV stores (like Consul) have limited entry size the certificates list is compressed before it is saved as KV store entry.
+
+!!! note
+    It is possible to store up to approximately 100 ACME certificates in Consul.
+
+#### ACME v2 Migration
+
+During migration from ACME v1 to ACME v2, using a storage file, a backup of the original file is created in the same place as the latter (with a `.bak` extension).
+
+For example: if `acme.storage`'s value is `/etc/traefik/acme/acme.json`, the backup file will be `/etc/traefik/acme/acme.json.bak`.
+
+!!! note
+    When Traefik is launched in a container, the storage file's parent directory needs to be mounted to be able to access the backup file on the host.
+    Otherwise the backup file will be deleted when the container is stopped. Traefik will only generate it once!
+
+### `dnsProvider` (Deprecated)
+
+!!! danger "DEPRECATED"
+    This option is deprecated. Please use [dnsChallenge.provider](/configuration/acme/#provider) instead.
+
+### `delayDontCheckDNS` (Deprecated)
+
+!!! danger "DEPRECATED"
+    This option is deprecated. Please use [dnsChallenge.delayBeforeCheck](/configuration/acme/#dnschallenge) instead.
+
+## Fallbacks
+
+If Let's Encrypt is not reachable, these certificates will be used:
+
+  1. ACME certificates already generated before downtime
+  1. Expired ACME certificates
+  1. Provided certificates
+
+!!! note
+    For new (sub)domains which need Let's Encrypt authentification, the default Traefik certificate will be used until Traefik is restarted.

+## Security
+
+Enabling the API will expose all configuration elements,
+including sensitive data.
+
+It is not recommended in production,
+unless secured by authentication and authorizations.
+
+A good sane default (but not exhaustive) set of recommendations
+would be to apply the following protection mechanism:
+
+* _At application level:_ enabling HTTP [Basic Authentication](#authentication)
+* _At transport level:_ NOT exposing publicly the API's port,
+keeping it restricted over internal networks
+(restricted networks as in https://en.wikipedia.org/wiki/Principle_of_least_privilege).

+<1> See [Rest](/configuration/backends/rest/#api) for more information.
+
+!!! warning
+    For compatibility reason, when you activate the rest provider, you can use `web` or `rest` as `provider` value.
+    But be careful, in the configuration for all providers the key is still `web`.
+
+### Address / Port
+
+You can define a custom address/port like this:
+
+```toml
+defaultEntryPoints = ["http"]
+
+[entryPoints]
+  [entryPoints.http]
+  address = ":80"
+
+  [entryPoints.foo]
+  address = ":8082"
+
+  [entryPoints.bar]
+  address = ":8083"
+
+[ping]
+entryPoint = "foo"
+
+[api]
+entryPoint = "bar"
+```
+
+In the above example, you would access a regular path, dashboard, and health-check as follows:
+
+* Regular path: `http://hostname:80/path`
+* Dashboard: `http://hostname:8083/`
+* Ping URL: `http://hostname:8082/ping`
+
+In the above example, it is _very_ important to create a named dedicated entry point, and do **not** include it in `defaultEntryPoints`.
+Otherwise, you are likely to expose _all_ services via that entry point.
+
+### Custom Path
+
+You can define a custom path like this:
+
+```toml
+defaultEntryPoints = ["http"]
+
+[entryPoints]
+  [entryPoints.http]
+  address = ":80"
+
+  [entryPoints.foo]
+  address = ":8080"
+
+  [entryPoints.bar]
+  address = ":8081"
+
+# Activate API and Dashboard
+[api]
+entryPoint = "bar"
+dashboard = true
+
+[file]
+  [backends]
+    [backends.backend1]
+      [backends.backend1.servers.server1]
+      url = "http://127.0.0.1:8081"
+
+  [frontends]
+    [frontends.frontend1]
+    entryPoints = ["foo"]
+    backend = "backend1"
+      [frontends.frontend1.routes.test_1]
+      rule = "PathPrefixStrip:/yourprefix;PathPrefix:/yourprefix"
+```
+
+### Authentication
+
+You can define the authentication like this:
+
+```toml
+defaultEntryPoints = ["http"]
+
+[entryPoints]
+  [entryPoints.http]
+  address = ":80"
+
+ [entryPoints.foo]
+   address=":8080"
+   [entryPoints.foo.auth]
+     [entryPoints.foo.auth.basic]
+       users = [
+         "test:$apr1$H6uskkkW$IgXLP6ewTrSuBkTrqE8wj/",
+         "test2:$apr1$d9hr9HBB$4HxwgUir3HP4EsggP/QNo0",
+       ]
+
+[api]
+entrypoint="foo"
+```

+### Multiple frontends for a single service
+
+If you need to support multiple frontends for a service, for example when having multiple `rules` that can't be combined, specify them as follows:
+
+```
+<prefix>.frontends.A.rule=Host:A:PathPrefix:/A
+<prefix>.frontends.B.rule=Host:B:PathPrefix:/
+```
+
+`A` and `B` here are just arbitrary names, they can be anything. You can use any setting that applies to `<prefix>.frontend` from the table above.

+### Examples
+
+If you want that Traefik uses Consul tags correctly you need to defined them like that:
+
+```js
+traefik.enable=true
+traefik.tags=api
+traefik.tags=external
+```
+
+If the prefix defined in Traefik configuration is `bla`, tags need to be defined like that:
+
+```js
+bla.enable=true
+bla.tags=api
+bla.tags=external
+```

+## Security Considerations
+
+### Security Challenge with the Docker Socket
+
+Traefik requires access to the docker socket to get its dynamic configuration,
+by watching the Docker API through this socket.
+
+!!! important
+    Depending on your context and your usage, accessing the Docker API without any restriction might be a security concern.
+
+As explained on the Docker documentation: ([Docker Daemon Attack Surface page](https://docs.docker.com/engine/security/security/#docker-daemon-attack-surface)):
+
+`[...] only **trusted** users should be allowed to control your Docker daemon [...]`
+
+If the Traefik processes (handling requests from the outside world) is attacked,
+then the attacker can access the Docker (or Swarm Mode) backend.
+
+Also, when using Swarm Mode, it is mandatory to schedule Traefik's containers on the Swarm manager nodes,
+to let Traefik accessing the Docker Socket of the Swarm manager node.
+

+
+### Workarounds
+
+!!! note "Improved Security"
+
+    [TraefikEE](https://containo.us/traefikee) solves this problem by separating the control plane (connected to Docker) and the data plane (handling the requests).
+
+Another possible workaround is to expose the Docker socket over TCP, instead of the default Unix socket file.
+It allows different implementation levels of the [AAA (Authentication, Authorization, Accounting) concepts](https://en.wikipedia.org/wiki/AAA_(computer_security)), depending on your security assessment:
+
+- Authentication with Client Certificates as described in [the "Protect the Docker daemon socket" page of Docker's documentation](https://docs.docker.com/engine/security/https/)
+
+- Authorization with the [Docker Authorization Plugin Mechanism](https://docs.docker.com/engine/extend/plugins_authorization/)
+
+- Accounting at networking level, by exposing the socket only inside a Docker private network, only available for Traefik.
+
+- Accounting at container level, by exposing the socket on a another container than Traefik's.
+  With Swarm mode, it allows scheduling of Traefik on worker nodes, with only the "socket exposer" container on the manager nodes.
+
+- Accounting at kernel level, by enforcing kernel calls with mechanisms like [SELinux](https://en.wikipedia.org/wiki/Security-Enhanced_Linux),
+  to only allows an identified set of actions for Traefik's process (or the "socket exposer" process).
+
+Use the following ressources to get started:

+
+## Labels: overriding default behavior
+
+### Using Docker with Swarm Mode
+
+If you use a compose file with the Swarm mode, labels should be defined in the `deploy` part of your service.
+This behavior is only enabled for docker-compose version 3+ ([Compose file reference](https://docs.docker.com/compose/compose-file/#labels-1)).
+
+```yaml
+version: "3"
+services:
+  whoami:
+    deploy:
+      labels:
+        traefik.docker.network: traefik
+```
+
+Required labels:
+
+- `traefik.frontend.rule`
+- `traefik.port` - Without this the debug logs will show this service is deliberately filtered out.
+- `traefik.docker.network` - Without this a 504 may occur.
+
+#### Troubleshooting
+
+If service doesn't show up in the dashboard, check the debug logs to see if the port is missing:
+`Filtering container without port, <SERVICE_NAME>: port label is missing, ...')`
+
+If `504 Gateway Timeout` occurs and there are networks used, ensure that `traefik.docker.network` is defined. 
+The complete name is required, meaning if the network is internal the name needs to be `<project_name>_<network_name>`.
+
+### Using Docker Compose
+
+If you are intending to use only Docker Compose commands (e.g. `docker-compose up --scale whoami=2 -d`), labels should be under your service, otherwise they will be ignored.
+
+```yaml
+version: "3"
+services:
+  whoami:
+    labels:
+      traefik.docker.network: traefik
+```
+
+### On Containers
+
+Labels can be used on containers to override default behavior.

-### Services labels can be used for overriding default behaviour
+[1] `traefik.docker.network`:  
+If a container is linked to several networks, be sure to set the proper network name (you can check with `docker inspect <container_id>`) otherwise it will randomly pick one (depending on how docker is returning them).  
+For instance when deploying docker `stack` from compose files, the compose defined networks will be prefixed with the `stack` name.
+Or if your service references external network use it's name instead.
+
+[2] `traefik.frontend.auth.basic.users=EXPR`:  
+To create `user:password` pair, it's possible to use this command:  
+`echo $(htpasswd -nb user password) | sed -e s/\\$/\\$\\$/g`.  
+The result will be `user:$$apr1$$9Cv/OMGj$$ZomWQzuQbL.3TRCS81A1g/`, note additional symbol `$` makes escaping.
+
+[3] `traefik.backend.loadbalancer.swarm`:  
+If you enable this option, Traefik will use the virtual IP provided by docker swarm instead of the containers IPs.
+Which means that Traefik will not perform any kind of load balancing and will delegate this task to swarm.  
+It also means that Traefik will manipulate only one backend, not one backend per container.

+### On containers with Multiple Ports (segment labels)
+
+Segment labels are used to define routes to a container exposing multiple ports.
+A segment is a group of labels that apply to a port exposed by a container.
+You can define as many segments as ports exposed in a container.
+
+Segment labels override the default behavior.

+!!! note
+    If a label is defined both as a `container label` and a `segment label` (for example `traefik.<segment_name>.port=PORT` and `traefik.port=PORT` ), the `segment label` is used to defined the `<segment_name>` property (`port` in the example).
+
+    It's possible to mix `container labels` and `segment labels`, in this case `container labels` are used as default value for missing `segment labels` but no frontends are going to be created with the `container labels`.
+
+    More details in this [example](/user-guide/docker-and-lets-encrypt/#labels).

+
+## usebindportip
+
+The default behavior of Traefik is to route requests to the IP/Port of the matching container.
+When setting `usebindportip` to true, you tell Traefik to use the IP/Port attached to the container's binding instead of the inner network IP/Port.
+
+When used in conjunction with the `traefik.port` label (that tells Traefik to route requests to a specific port), Traefik tries to find a binding with `traefik.port` port to select the container. If it can't find such a binding, Traefik falls back on the internal network IP of the container, but still uses the `traefik.port` that is set in the label.
+
+Below is a recap of the behavior of `usebindportip` in different situations.
+
+| traefik.port label | Container's binding                                | Routes to      |

+## Table Items
+
 Items in the `dynamodb` table must have three attributes:
 
 - `id` (string): The id is the primary key.
 - `name`(string): The name is used as the name of the frontend or backend.
-- `frontend` or `backend` (map): This attribute's structure matches exactly the structure of a Frontend or Backend type in traefik.  
+- `frontend` or `backend` (map): This attribute's structure matches exactly the structure of a Frontend or Backend type in Traefik.  
     See `types/types.go` for details.  
     The presence or absence of this attribute determines its type.
     So an item should never have both a `frontend` and a `backend` attribute.

+### Containers with Multiple Ports (segment labels)
+
+Segment labels are used to define routes to an application exposing multiple ports.
+A segment is a group of labels that apply to a port exposed by an application.
+You can define as many segments as ports exposed in an application.
+
+Segment labels override the default behavior.

+## Configuration Mode
+
+You have two choices:
+
+- [Rules in Traefik configuration file](/configuration/backends/file/#rules-in-traefik-configuration-file)
+- [Rules in dedicated files](/configuration/backends/file/#rules-in-dedicated-files)
+
+To enable the file backend, you must either pass the `--file` option to the Traefik binary or put the `[file]` section (with or without inner settings) in the configuration file.
+
+The configuration file allows managing both backends/frontends and HTTPS certificates (which are not [Let's Encrypt](https://letsencrypt.org) certificates generated through Traefik).
+
+TOML templating can be used if rules are not defined in the Traefik configuration file.
+

-## Rules in a Separate File
+!!! note
+    If `tls.entryPoints` is not defined, the certificate is attached to all the `defaultEntryPoints` with a TLS configuration.
 
-Put your rules in a separate file, for example `rules.toml`:
+!!! note
+    Adding certificates directly to the entryPoint is still maintained but certificates declared in this way cannot be managed dynamically.
+    It's recommended to use the file provider to declare certificates.
+
+!!! warning
+    TOML templating cannot be used if rules are defined in the Traefik configuration file.
+
+### Rules in Dedicated Files
+
+Traefik allows defining rules in one or more separate files.
+
+#### One Separate File
+
+You have to specify the file path in the `file.filename` option.
 
 ```toml
 # traefik.toml
+defaultEntryPoints = ["http", "https"]
+
 [entryPoints]
   [entryPoints.http]
-  address = ":80"
-    [entryPoints.http.redirect]
-      entryPoint = "https"
+    # ...
   [entryPoints.https]
-  address = ":443"
-    [entryPoints.https.tls]
-      [[entryPoints.https.tls.certificates]]
-      CertFile = "integration/fixtures/https/snitest.com.cert"
-      KeyFile = "integration/fixtures/https/snitest.com.key"
-      [[entryPoints.https.tls.certificates]]
-      CertFile = "integration/fixtures/https/snitest.org.cert"
-      KeyFile = "integration/fixtures/https/snitest.org.key"
+    # ...
 
 [file]
-filename = "rules.toml"
+  filename = "rules.toml"
+  watch = true
 ```
 
+The option `file.watch` allows Traefik to watch file changes automatically.
+
+#### Multiple Separated Files
+
+You could have multiple `.toml` files in a directory (and recursively in its sub-directories):
+
+```toml
+[file]
+  directory = "/path/to/config/"
+  watch = true
+```
+
+The option `file.watch` allows Traefik to watch file changes automatically.
+
+#### Separate Files Content
+
+If you are defining rules in one or more separate files, you can use two formats.
+
+##### Simple Format
+
+Backends, Frontends and TLS certificates are defined one at time, as described in the file `rules.toml`:
+

-## Multiple .toml Files
+##### TOML Templating
 
-You could have multiple `.toml` files in a directory:
+!!! warning
+    TOML templating can only be used **if rules are defined in one or more separate files**.
+    Templating will not work in the Traefik configuration file.
+
+Traefik allows using TOML templating.
+
+Thus, it's possible to define easily lot of Backends, Frontends and TLS certificates as described in the file `template-rules.toml` :
 
 ```toml
-[file]
-directory = "/path/to/config/"
-```
+# template-rules.toml
+[backends]
+{{ range $i, $e := until 100 }}
+  [backends.backend{{ $e }}]
+    #...
+{{ end }}
 
-If you want Træfik to watch file changes automatically, just add:
+[frontends]
+{{ range $i, $e := until 100 }}
+  [frontends.frontend{{ $e }}]
+    #...
+{{ end }}
 
-```toml
-[file]
-watch = true
+
+# HTTPS certificate
+{{ range $i, $e := until 100 }}
+[[tls]]
+    #...
+{{ end }}
 ```

-Annotations can be used on containers to override default behaviour for the whole Ingress resource:
+### `endpoint`
 
-- `traefik.frontend.rule.type: PathPrefixStrip`: override the default frontend rule type (Default: `PathPrefix`).
-- `traefik.frontend.priority: 3`: override the default frontend rule priority (Default: `len(Path)`).
+The Kubernetes server endpoint as URL.
 
-Annotations can be used on the Kubernetes service to override default behaviour:
+When deployed into Kubernetes, Traefik will read the environment variables `KUBERNETES_SERVICE_HOST` and `KUBERNETES_SERVICE_PORT` to construct the endpoint.
 
-- `traefik.backend.loadbalancer.method=drr`: override the default `wrr` load balancer algorithm
-- `traefik.backend.loadbalancer.sticky=true`: enable backend sticky sessions
+The access token will be looked up in `/var/run/secrets/kubernetes.io/serviceaccount/token` and the SSL CA certificate in `/var/run/secrets/kubernetes.io/serviceaccount/ca.crt`.
+Both are provided mounted automatically when deployed inside Kubernetes.
 
-You can find here an example [ingress](https://raw.githubusercontent.com/containous/traefik/master/examples/k8s/cheese-ingress.yaml) and [replication controller](https://raw.githubusercontent.com/containous/traefik/master/examples/k8s/traefik.yaml).
+The endpoint may be specified to override the environment variable values inside a cluster.
 
-Additionally, an annotation can be used on Kubernetes services to set the [circuit breaker expression](https://docs.traefik.io/basics/#backends) for a backend.
+When the environment variables are not found, Traefik will try to connect to the Kubernetes API server with an external-cluster client.
+In this case, the endpoint is required.
+Specifically, it may be set to the URL used by `kubectl proxy` to connect to a Kubernetes cluster using the granted authentication and authorization of the associated kubeconfig.
 
-- `traefik.backend.circuitbreaker: <expression>`: set the circuit breaker expression for the backend (Default: nil).
+### `labelselector`
 
-As known from nginx when used as Kubernetes Ingress Controller, a List of IP-Ranges which are allowed to access can be configured by using an ingress annotation:
+By default, Traefik processes all Ingress objects in the configured namespaces.
+A label selector can be defined to filter on specific Ingress objects only.
 
-- `ingress.kubernetes.io/whitelist-source-range: "1.2.3.0/24, fe80::/16"`
+See [label-selectors](https://kubernetes.io/docs/concepts/overview/working-with-objects/labels/#label-selectors) for details.
 
-An unset or empty list allows all Source-IPs to access. If one of the Net-Specifications are invalid, the whole list is invalid and allows all Source-IPs to access.
+### `ingressEndpoint`
 
+You can configure a static hostname or IP address that Traefik will add to the status section of Ingress objects that it manages.
+If you prefer, you can provide a service, which traefik will copy the status spec from.
+This will give more flexibility in cloud/dynamic environments.
+
+### TLS communication between Traefik and backend pods
+
+Traefik automatically requests endpoint information based on the service provided in the ingress spec.
+Although traefik will connect directly to the endpoints (pods), it still checks the service port to see if TLS communication is required.
+
+There are 3 ways to configure Traefik to use https to communicate with backend pods:
+
+1. If the service port defined in the ingress spec is 443 (note that you can still use `targetPort` to use a different port on your pod).
+2. If the service port defined in the ingress spec has a name that starts with `https` (such as `https-api`, `https-web` or just `https`).
+3. If the ingress spec includes the annotation `ingress.kubernetes.io/protocol: https`.
+
+If either of those configuration options exist, then the backend communication protocol is assumed to be TLS, and will connect via TLS automatically.
+
+!!! note
+    Please note that by enabling TLS communication between traefik and your pods, you will have to have trusted certificates that have the proper trust chain and IP subject name.
+    If this is not an option, you may need to skip TLS certificate verification.
+    See the [insecureSkipVerify](/configuration/commons/#main-section) setting for more details.

+
+<1> `traefik.ingress.kubernetes.io/app-root`:
+Non-root paths will not be affected by this annotation and handled normally.
+This annotation may not be combined with other redirect annotations.
+Trying to do so will result in the other redirects being ignored.
+This annotation can be used in combination with `traefik.ingress.kubernetes.io/redirect-permanent` to configure whether the `app-root` redirect is a 301 or a 302.
+
+<2> `traefik.ingress.kubernetes.io/error-pages` example:
+
+```yaml
+foo:
+  status:
+  - "404"
+  backend: bar
+  query: /bar
+fii:
+  status:
+  - "503"
+  - "500"
+  backend: bar
+  query: /bir
+```
+
+<3> `traefik.ingress.kubernetes.io/pass-client-tls-cert` example:
+
+```yaml
+# add escaped pem in the `X-Forwarded-Tls-Client-Cert` header
+pem: true
+# add escaped certificate following infos in the `X-Forwarded-Tls-Client-Cert-Infos` header
+infos:
+  notafter: true
+  notbefore: true
+  sans: true
+  subject:
+    country: true
+    province: true
+    locality: true
+    organization: true
+    commonname: true
+    serialnumber: true
+```
+
+If `pem` is set, it will add a `X-Forwarded-Tls-Client-Cert` header that contains the escaped pem as value.
+If at least one flag of the `infos` part is set, it will add a `X-Forwarded-Tls-Client-Cert-Infos` header that contains an escaped string composed of the client certificate data selected by the infos flags.
+This infos part is composed like the following example (not escaped):
+```
+Subject="C=FR,ST=SomeState,L=Lyon,O=Cheese,CN=*.cheese.org",NB=1531900816,NA=1563436816,SAN=*.cheese.org,*.cheese.net,cheese.in,test@cheese.org,test@cheese.net,10.0.1.0,10.0.1.2
+```
+
+Note these options work only with certificates issued by CAs included in the applicable [EntryPoint ClientCA section](/configuration/entrypoints/#tls-mutual-authentication); certificates from other CAs are not parsed or passed through as-is.
+
+<4> `traefik.ingress.kubernetes.io/rate-limit` example:
+
+```yaml
+extractorfunc: client.ip
+rateset:
+  bar:
+    period: 3s
+    average: 6
+    burst: 9
+  foo:
+    period: 6s
+    average: 12
+    burst: 18
+```
+
+<5> `traefik.ingress.kubernetes.io/rule-type`
+Note: `ReplacePath` is deprecated in this annotation, use the `traefik.ingress.kubernetes.io/request-modifier` annotation instead. Default: `PathPrefix`.
+
+<6> `traefik.ingress.kubernetes.io/service-weights`:
+Service weights enable to split traffic across multiple backing services in a fine-grained manner.
+
+Example:
+
+```yaml
+service_backend1: 12.50%
+service_backend2: 12.50%
+service_backend3: 75 # Same as 75%, the percentage sign is optional
+```
+
+A single service backend definition may be omitted; in this case, Traefik auto-completes that service backend to 100% automatically.
+Conveniently, users need not bother to compute the percentage remainder for a main service backend.
+For instance, in the example above `service_backend3` does not need to be specified to be assigned 75%.
+
+!!! note
+    For each service weight given, the Ingress specification must include a backend item with the corresponding `serviceName` and (if given) matching path.
+
+Currently, 3 decimal places for the weight are supported.
+An attempt to exceed the precision should be avoided as it may lead to percentage computation flaws and, in consequence, Ingress parsing errors.
+
+For each path definition, this annotation will fail if:
+
+- the sum of backend weights exceeds 100% or
+- the sum of backend weights is less than 100% without one or more omitted backends
+
+See also the [user guide section traffic splitting](/user-guide/kubernetes/#traffic-splitting).
+
+<7> `traefik.ingress.kubernetes.io/whitelist-source-range`:
+All source IPs are permitted if the list is empty or a single range is ill-formatted.
+Please note, you may have to set `service.spec.externalTrafficPolicy` to the value `Local` to preserve the source IP of the request for filtering.
+Please see [this link](https://kubernetes.io/docs/tutorials/services/source-ip/) for more information.
+
+
+!!! note
+    Please note that `traefik.ingress.kubernetes.io/redirect-regex` and `traefik.ingress.kubernetes.io/redirect-replacement` do not have to be set if `traefik.ingress.kubernetes.io/redirect-entry-point` is defined for the redirection (they will not be used in this case).
+
+The following annotations are applicable on the Service object associated with a particular Ingress object:
+

 ### Authentication
 
-Is possible to add additional authentication annotations in the Ingress rule.
-The source of the authentication is a secret that contains usernames and passwords inside the the key auth.
+Additional authentication annotations can be added to the Ingress object.
+The source of the authentication is a Secret object that contains the credentials.
 
-- `ingress.kubernetes.io/auth-type`: `basic`
-- `ingress.kubernetes.io/auth-secret`: contains the usernames and passwords with access to the paths defined in the Ingress Rule.

-The secret must be created in the same namespace as the Ingress rule.
+The secret must be created in the same namespace as the Ingress object.
 
-Limitations:
+The following limitations hold for basic/digest auth:
 
-- Basic authentication only.
-- Realm not configurable; only `traefik` default.
-- Secret must contain only single file.
+- The realm is not configurable; the only supported (and default) value is `traefik`.
+- The Secret must contain a single file only.
+
+### TLS certificates management
+
+TLS certificates can be managed in Secrets objects.
+More information are available in the  [User Guide](/user-guide/kubernetes/#add-a-tls-certificate-to-the-ingress).
+
+!!! note
+    Only TLS certificates provided by users can be stored in Kubernetes Secrets.
+    [Let's Encrypt](https://letsencrypt.org) certificates cannot be managed in Kubernets Secrets yet.
+
+### Global Default Backend Ingresses
+
+Ingresses can be created that look like the following:
+
+```yaml
+apiVersion: extensions/v1beta1
+kind: Ingress
+metadata:
+  name: cheese
+spec:
+  backend:
+    serviceName: stilton
+    servicePort: 80
+```
+
+This ingress follows the [Global Default Backend](https://kubernetes.io/docs/concepts/services-networking/ingress/#the-ingress-resource) property of ingresses.
+This will allow users to create a "default backend" that will match all unmatched requests.
+
+!!! note
+    Due to Traefik's use of priorities, you may have to set this ingress priority lower than other ingresses in your environment, to avoid this global ingress from satisfying requests that _could_ match other ingresses.
+    To do this, use the `traefik.ingress.kubernetes.io/priority` annotation (as seen in [General Annotations](/configuration/backends/kubernetes/#general-annotations)) on your ingresses accordingly.

+
+## Labels: overriding default behavior
+
+Marathon labels may be used to dynamically change the routing and forwarding behavior.
+
+They may be specified on one of two levels: Application or service.
+
+### Application Level
+
+The following labels can be defined on Marathon applications. They adjust the behavior for the entire application.

+### Applications with Multiple Ports (segment labels)
+
+Segment labels are used to define routes to an application exposing multiple ports.
+A segment is a group of labels that apply to a port exposed by an application.
+You can define as many segments as ports exposed in an application.
+
+Segment labels override the default behavior.

+Segment labels are used to define routes to an application exposing multiple ports.
+A segment is a group of labels that apply to a port exposed by an application.
+You can define as many segments as ports exposed in an application.
+
+Additionally, if a segment name matches a named port, that port will be used unless `portIndex`, `portName`, or `port` labels are specified for that segment.
+
+Segment labels override the default behavior.
+

+### On containers with Multiple Ports (segment labels)
+
+Segment labels are used to define routes to a container exposing multiple ports.
+A segment is a group of labels that apply to a port exposed by a container.
+You can define as many segments as ports exposed in a container.
+
+Segment labels override the default behavior.

+# Azure Service Fabric Provider
+
+Traefik can be configured to use Azure Service Fabric as a provider.
+
+See [this repository for an example deployment package and further documentation.](https://aka.ms/traefikonsf)
+
+## Azure Service Fabric
+
+```toml
+################################################################
+# Azure Service Fabric Provider
+################################################################
+
+# Enable Azure Service Fabric Provider
+[serviceFabric]
+
+# Azure Service Fabric Management Endpoint
+#
+# Required
+#
+clusterManagementUrl = "https://localhost:19080"
+
+# Azure Service Fabric Management Endpoint API Version
+#
+# Required
+# Default: "3.0"
+#
+apiVersion = "3.0"
+
+# Azure Service Fabric Polling Interval (in seconds)
+#
+# Required
+# Default: 10
+#
+refreshSeconds = 10
+
+# Enable TLS connection.
+#
+# Optional
+#
+# [serviceFabric.tls]
+#   ca = "/etc/ssl/ca.crt"
+#   cert = "/etc/ssl/servicefabric.crt"
+#   key = "/etc/ssl/servicefabric.key"
+#   insecureSkipVerify = true
+```
+
+## Labels
+
+The provider uses labels to configure how services are exposed through Traefik.
+These can be set using Extensions and the Property Manager API
+
+#### Extensions
+
+Set labels with extensions through the services `ServiceManifest.xml` file.
+Here is an example of an extension setting Traefik labels:
+
+```xml
+<StatelessServiceType ServiceTypeName="WebServiceType">
+  <Extensions>
+      <Extension Name="Traefik">
+        <Labels xmlns="http://schemas.microsoft.com/2015/03/fabact-no-schema">
+          <Label Key="traefik.frontend.rule.example2">PathPrefixStrip: /a/path/to/strip</Label>
+          <Label Key="traefik.enable">true</Label>
+          <Label Key="traefik.frontend.passHostHeader">true</Label>
+        </Labels>
+      </Extension>
+  </Extensions>
+</StatelessServiceType>
+```
+
+> **Note**: The `Label` tag and its `Key` attribute are case sensitive. That is, if you use `label` instead of `Label` or `key` instead of `Key`, they will be silently ignored.
+
+#### Property Manager
+
+Set Labels with the property manager API to overwrite and add labels, while your service is running.
+Here is an example of adding a frontend rule using the property manager API.
+
+```shell
+curl -X PUT \
+  'http://localhost:19080/Names/GettingStartedApplication2/WebService/$/GetProperty?api-version=6.0&IncludeValues=true' \
+  -d '{
+  "PropertyName": "traefik.frontend.rule.default",
+  "Value": {
+    "Kind": "String",
+    "Data": "PathPrefixStrip: /a/path/to/strip"
+  },
+  "CustomTypeId": "LabelType"
+}'
+```
+
+!!! note
+    This functionality will be released in a future version of the [sfctl](https://docs.microsoft.com/en-us/azure/service-fabric/service-fabric-application-lifecycle-sfctl) tool.
+
+## Available Labels
+
+Labels, set through extensions or the property manager, can be used on services to override default behavior.

+### Deprecation compatibility
+
+#### Address
+
+As the web provider is deprecated, you can handle the `Address` option like this:
+
+```toml
+defaultEntryPoints = ["http"]
+
+[entryPoints]
+  [entryPoints.http]
+  address = ":80"
+
+  [entryPoints.foo]
+  address = ":8082"
+
+  [entryPoints.bar]
+  address = ":8083"
+
+[ping]
+entryPoint = "foo"
+
+[api]
+entryPoint = "bar"
+```
+
+In the above example, you would access a regular path, administration panel, and health-check as follows:
+
+* Regular path: `http://hostname:80/path`
+* Admin Panel: `http://hostname:8083/`
+* Ping URL: `http://hostname:8082/ping`
+
+In the above example, it is _very_ important to create a named dedicated entry point, and do **not** include it in `defaultEntryPoints`.
+Otherwise, you are likely to expose _all_ services via that entry point.
+
+#### Path
+
+As the web provider is deprecated, you can handle the `Path` option like this:
+
+```toml
+defaultEntryPoints = ["http"]
+
+[entryPoints]
+  [entryPoints.http]

+
+  [entryPoints.foo]
+  address = ":8080"

+#### Authentication
+
+As the web provider is deprecated, you can handle the `auth` option like this:
+
+```toml

+
+[entryPoints]
+  [entryPoints.http]

-logLevel = "ERROR"
-```
-
-### Access Logs
-
-Access logs are written when `[accessLog]` is defined.
-By default it will write to stdout and produce logs in the textual Common Log Format (CLF), extended with additional fields.
-
-To enable access logs using the default settings just add the `[accessLog]` entry.
-```toml
-[accessLog]
-```
-
-To write the logs into a logfile specify the `filePath`.
-```toml
-[accessLog]
-filePath = "/path/to/access.log"
-```
-
-To write JSON format logs, specify `json` as the format:
-```toml
-[accessLog]
-filePath = "/path/to/access.log"
-format = "json"
-```
-
-Deprecated way (before 1.4):
-```toml
-# Access logs file
-#
-# DEPRECATED - see [accessLog] lower down
-#
-accessLogsFile = "log/access.log"
-```
-
-### Log Rotation
-
-Traefik will close and reopen its log files, assuming they're configured, on receipt of a USR1 signal.
-This allows the logs to be rotated and processed by an external program, such as `logrotate`.
-
-!!! note
-    that this does not work on Windows due to the lack of USR signals.

 ## Custom Error pages
 
 Custom error pages can be returned, in lieu of the default, according to frontend-configured ranges of HTTP Status codes.
+
 In the example below, if a 503 status is returned from the frontend "website", the custom error page at http://2.3.4.5/503.html is returned with the actual status code set in the HTTP header.

+## Rate limiting
+
+Rate limiting can be configured per frontend.  
+Multiple sets of rates can be added to each frontend, but the time periods must be unique.
+
+```toml
+[frontends]
+    [frontends.frontend1]
+      # ...
+      [frontends.frontend1.ratelimit]
+        extractorfunc = "client.ip"

+          [frontends.frontend1.ratelimit.rateset.rateset2]
+            period = "3s"
+            average = 5
+            burst = 10
+```
+
+In the above example, frontend1 is configured to limit requests by the client's ip address.  
+An average of 100 requests every 10 seconds is allowed and an average of 5 requests every 3 seconds.  
+These can "burst" up to 200 and 10 in each period respectively. 
+
+Valid values for `extractorfunc` are:
+  * `client.ip`
+  * `request.host`
+  * `request.header.<header name>`
+
+## Buffering
+
+In some cases request/buffering can be enabled for a specific backend.
+By enabling this, Traefik will read the entire request into memory (possibly buffering large requests into disk) and will reject requests that are over a specified limit.
+This may help services deal with large data (multipart/form-data for example) more efficiently and should minimise time spent when sending data to a backend server.
+
+For more information please check [oxy/buffer](http://godoc.org/github.com/vulcand/oxy/buffer) documentation.
+
+Example configuration:
+
+```toml
+[backends]
+  [backends.backend1]

 ## TLS Mutual Authentication
 
-Only accept clients that present a certificate signed by a specified Certificate Authority (CA).
+TLS Mutual Authentication can be `optional` or not.
+
+* If `optional = true`, if a certificate is provided, verifies if it is signed by a specified Certificate Authority (CA). Otherwise proceeds without any certificate.
+* If `optional = false`, Traefik will only accept clients that present a certificate signed by a specified Certificate Authority (CA).
+
 `ClientCAFiles` can be configured with multiple `CA:s` in the same file or use multiple files containing one or several `CA:s`.
 The `CA:s` has to be in PEM format.

+## Traefik Logs
+
+By default the Traefik log is written to stdout in text format.
+
+To write the logs into a log file specify the `filePath`:
+
+```toml
+[traefikLog]
+  filePath = "/path/to/traefik.log"
+```
+
+To switch to JSON format instead of standard format (`common`), specify `json` as the format:
+
+```toml
+[traefikLog]
+  filePath = "/path/to/traefik.log"
+  format   = "json"
+```
+
+Deprecated way (before 1.4):
+
+!!! danger "DEPRECATED"
+    `traefikLogsFile` is deprecated, use [traefikLog](/configuration/logs/#traefik-logs) instead.
+
+```toml
+# Traefik logs file
+# If not defined, logs to stdout
+#
+# DEPRECATED - see [traefikLog] lower down
+# In case both traefikLogsFile and traefikLog.filePath are specified, the latter will take precedence.
+# Optional
+#
+traefikLogsFile = "log/traefik.log"
+```
+
+To customize the log level:
+
+```toml
+# Log level
+#
+# Optional
+# Default: "ERROR"
+#
+# Accepted values, in order of severity: "DEBUG", "INFO", "WARN", "ERROR", "FATAL", "PANIC"
+# Messages at and above the selected level will be logged.
+#
+logLevel = "ERROR"
+```
+
+## Access Logs
+
+Access logs are written when the entry `[accessLog]` is defined (or the command line flag `--accesslog`).
+By default it writes to stdout and produces logs in the textual [Common Log Format (CLF)](#clf-common-log-format), extended with additional fields.
+
+To enable access logs using the default settings, add the `[accessLog]` entry in your `traefik.toml` configuration file:
+
+```toml
+[accessLog]
+```
+
+To write the logs into a log file specify the `filePath`:
+
+```toml
+[accessLog]
+filePath = "/path/to/access.log"
+```
+
+To switch to JSON format instead of [Common Log Format (CLF)](#clf-common-log-format), specify `json` as the format:
+
+```toml
+[accessLog]
+filePath = "/path/to/access.log"
+format = "json"  # Default: "common"
+```
+
+To write the logs in async, specify `bufferingSize` as the format (must be >0):
+
+```toml
+[accessLog]
+filePath = "/path/to/access.log"
+# Buffering Size
+#
+# Optional
+# Default: 0
+#
+# Number of access log lines to process in a buffered way.
+#
+bufferingSize = 100
+```
+
+To filter logs you can specify a set of filters which are logically "OR-connected". Thus, specifying multiple filters will keep more access logs than specifying only one:
+
+```toml
+[accessLog]
+filePath = "/path/to/access.log"
+format = "json"  # Default: "common"
+
+  [accessLog.filters]
+
+  # statusCodes: keep access logs with status codes in the specified range
+  #
+  # Optional
+  # Default: []
+  #
+  statusCodes = ["200", "300-302"]
+
+  # retryAttempts: keep access logs when at least one retry happened
+  #
+  # Optional
+  # Default: false
+  #
+  retryAttempts = true
+
+  # minDuration: keep access logs when request took longer than the specified duration
+  #
+  # Optional
+  # Default: 0
+  #
+  minDuration = "10ms"
+```
+
+### CLF - Common Log Format
+
+By default, Traefik use the CLF (`common`) as access log format.
+
+```html

+You can customize the fields written in the access logs.
+The list of available fields is found below: [List of All Available Fields](#list-of-all-available-fields).
+
+Each field has a "mode" which defines if it is written or not in the access log lines.
+The possible values for the mode are:
+
+* `keep`: the field and its value are written on the access log line. This is the default behavior.
+* `drop`: the field is not written at all on the access log.
+
+To customize the fields, you must:
+
+* Switch to the JSON format (mandatory)
+* Define the "default mode" for all fields (default is `keep`)
+* OR Define the fields which does not follow the default mode
+
+```toml
+[accessLog]
+# Access Log Format
+#
+# Optional
+# Default: "common"
+#
+# Accepted values "common", "json"
+#
+format = "json"
+
+  [accessLog.fields]
+
+  # defaultMode
+  #
+  # Optional
+  # Default: "keep"
+  #
+  # Accepted values "keep", "drop"
+  #
+  defaultMode = "keep"
+
+  # Fields map which is used to override fields defaultMode
+  [accessLog.fields.names]
+    "ClientUsername" = "drop"
+    # ...
+```
+
+### Customize Headers
+
+Access logs prints the headers of each request, as fields of the access log line.
+You can customize which and how the headers are printed, likewise the other fields (see ["Customize Fields" section](#customize-fields)).
+
+Each header has a "mode" which defines how it is written in the access log lines.
+The possible values for the mode are:
+
+* `keep`: the header and its value are written on the access log line. This is the default behavior.
+* `drop`: the header is not written at all on the access log.
+* `redacted`: the header is written, but its value is redacted to avoid leaking sensitive information.
+
+To customize the headers, you must:
+
+* Switch to the JSON format (mandatory)
+* Define the "default mode" for all headers (default is `keep`)
+* OR Define the headers which does not follow the default mode
+
+!!! important
+    The headers are written with the prefix `request_` in the access log.
+    This prefix must not be included when specifying a header in the TOML configuration.
+
+    * Do: `"User-Agent" = "drop"`
+    * Don't: `"redacted_User-Agent" = "drop"`
+

+
+### Depreciation Notice
+
+Deprecated way (before 1.4):
+
+!!! danger "DEPRECATED"
+    `accessLogsFile` is deprecated, use [accessLog](/configuration/logs/#access-logs) instead.
+
+```toml
+# Access logs file
+#
+# DEPRECATED - see [accessLog]
+#
+accessLogsFile = "log/access.log"
+```
+
+## Log Rotation
+
+Traefik will close and reopen its log files, assuming they're configured, on receipt of a USR1 signal.
+This allows the logs to be rotated and processed by an external program, such as `logrotate`.
+
+!!! note
+    This does not work on Windows due to the lack of USR signals.
+
+## Time Zones
+
+The timestamp of each log line is in UTC time by default.
+
+If you want to use local timezone, you need to ensure the 3 following elements:
+
+1. Provide the timezone data into /usr/share/zoneinfo
+2. Set the environement variable TZ to the timezone to be used
+3. Specify the field StartLocal instead of StartUTC (works on default Common Log Format (CLF) as well as JSON)
+
+Example using docker-compose:
+
+```yml
+version: '3'
+
+services:
+  traefik:
+    image: containous/traefik:[latest stable version]
+    ports:
+      - "80:80"
+    environment:
+      - "TZ=US/Alaska"
+    command:
+      - --docker
+      - --accesslog
+      - --accesslog.fields.names="StartUTC=drop"
+    volumes:
+      - "/var/run/docker.sock:/var/run/docker.sock"
+      - "/usr/share/zoneinfo:/usr/share/zoneinfo:ro"
+```
