-- Glide is not required for building; however, it is necessary to modify dependencies (i.e., add, update, or remove third-party packages)
-- 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.

+
+```bash
+$ make docs
+docker build -t traefik-docs -f docs.Dockerfile .
+# […]
+docker run  --rm -v /home/user/go/github/containous/traefik:/mkdocs -p 8000:8000 traefik-docs mkdocs serve

+[I 170828 20:47:48 handlers:62] Start detecting changes
+```
+
+And go to [http://127.0.0.1:8000](http://127.0.0.1:8000).
+
+If you only want to build the documentation without serving it locally, you can use the following command:
+
+```bash
+$ make docs-build
+...
+```
+

+
+You can verify that the documentation meets some expectations, as checking for dead links, html markup validity.

+```
+
+If you recently changed the documentation, do not forget to clean it to have it rebuilt:
+
+```bash
+$ make docs-clean docs-verify
+...
+```

 ## 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 Træfik can help you!**
 
-Traditional reverse-proxies are not natively dynamic. You can't change their configuration and hot-reload easily.
+Træfik 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 Træfik and let it do the work for you!** 
+_(But if you'd rather configure some of your routes manually, Træfik 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!

-## Release cycle
-
-- Release: We try to release a new version every 2 months
-  - i.e.: 1.3.0, 1.4.0, 1.5.0
-- Release candidate: we do RC (1.**x**.0-rc**y**) before the final release (1.**x**.0)
-  - i.e.: 1.1.0-rc1 -> 1.1.0-rc2 -> 1.1.0-rc3 -> 1.1.0-rc4 -> 1.1.0
-- Bug-fixes: For each version we release bug fixes
-  - i.e.: 1.1.1, 1.1.2, 1.1.3
-  - those versions contain only bug-fixes
-  - no additional features are delivered in those versions
-- Each version is supported until the next one is released
-  - i.e.: 1.1.x will be supported until 1.2.0 is out
-- We use [Semantic Versioning](http://semver.org/)

+You can read the public proposal on this topic [here](https://github.com/containous/traefik/issues/2369).
+
+### Why ?
+
+In order to help us learn more about how Træfik 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 Træfik), we collect:
+
+- the Træfik 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).
+
+!!! note
+    We do not collect data behind the scenes to run advertising programs or to sell such data to third-party.

-### `delayDontCheckDNS`
+Redirection is fully compatible with the `HTTP-01` challenge.
 
 ```toml
 [acme]
 # ...
-delayDontCheckDNS = 0
+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
 # ...
 ```
 
-By default, the dnsProvider will verify the TXT DNS challenge record before letting ACME verify.  
-If `delayDontCheckDNS` is greater than zero, avoid this & instead just wait so many seconds.
+##### `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.
 
-### `onDemand`
+!!! 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.
+
+| Provider Name                                          | Provider Code  | Environment Variables                                                                                                           | Wildcard & Root Domain Support |

+!!! 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`).
+Due to ACME limitation it is not possible to define wildcards in SANs (alternative domains). Thus, the wildcard domain has to be defined as a main domain.
+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.
+Eventhough 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 Træfik ACME client library [LEGO](https://github.com/xenolf/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.

+
+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 Træfik 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 Træfik 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. Træfik will only generate it once!
+
+### `dnsProvider` (Deprecated)
+
+!!! danger "DEPRECATED"

+
+## 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 Træfik certificate will be used until Træfik is restarted.

+
+### 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, 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.
+
+### 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

+  [frontends]
+    [frontends.frontend1]

+      [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 = [

+### 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 Træfik 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 Træfik configuration is `bla`, tags need to be defined like that:
+
+```js
+bla.enable=true
+bla.tags=api
+bla.tags=external
+```

-## Labels: overriding default behaviour
+## 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
+```
+
+### 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 Service
+[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.
 
-Services labels can be used for overriding default behaviour
+[2] `traefik.frontend.auth.basic.users=EXPR `:  
+To create `user:password` pair, it's possible to use this command:

+The result will be `user:$$apr1$$9Cv/OMGj$$ZomWQzuQbL.3TRCS81A1g/`, note additional symbol `$` makes escaping.

+### 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.

+### 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 Træfik configuration file](/configuration/backends/file/#rules-in-trfik-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 Træfik binary or put the `[file]` section (with or without inner settings) in the configuration file.
 
-## Simple
+The configuration file allows managing both backends/frontends and HTTPS certificates (which are not [Let's Encrypt](https://letsencrypt.org) certificates generated through Træfik).
+
+TOML templating can be used if rules are not defined in the Træfik configuration file.
+
+### Rules in Træfik Configuration File
 
 Add your configuration at the end of the global configuration file `traefik.toml`:

-## 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 Træfik configuration file.
+
+### Rules in Dedicated Files
+
+Træfik 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 Træfik 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 Træfik 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`:
+

   [frontends.frontend1]
-  backend = "backend2"
-    [frontends.frontend1.routes.test_1]
-    rule = "Host:test.localhost"
+  # ...
   [frontends.frontend2]
-  backend = "backend1"
-  passHostHeader = true
-  priority = 10
-  entrypoints = ["https"] # overrides defaultEntryPoints
-    [frontends.frontend2.routes.test_1]
-    rule = "Host:{subdomain:[a-z]+}.localhost"
+  # ...
   [frontends.frontend3]
-  entrypoints = ["http", "https"] # overrides defaultEntryPoints
-  backend = "backend2"
-  rule = "Path:/test"
+  # ...
+
+# HTTPS certificate
+[[tls]]
+  # ...
+
+[[tls]]
+  # ...
 ```
 
-## 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 Træfik configuration file.
+
+Træfik 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 }}

 ### `endpoint`
 
-The Kubernetes server endpoint.
+The Kubernetes server endpoint as URL.
 
-When deployed as a replication controller in Kubernetes, Traefik will use the environment variables `KUBERNETES_SERVICE_HOST` and `KUBERNETES_SERVICE_PORT` to construct the endpoint.
+When deployed into Kubernetes, Traefik will read the environment variables `KUBERNETES_SERVICE_HOST` and `KUBERNETES_SERVICE_PORT` to construct the endpoint.
 
-Secure token will be found in `/var/run/secrets/kubernetes.io/serviceaccount/token` and SSL CA cert in `/var/run/secrets/kubernetes.io/serviceaccount/ca.crt`
+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.
 
-The endpoint may be given to override the environment variable values.
+The endpoint may be specified to override the environment variable values inside a cluster.
 
 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 from localhost.
+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.
 
 ### `labelselector`
 
-Ingress label selector to identify Ingress objects that should be processed.
+By default, Traefik processes all Ingress objects in the configured namespaces.
+A label selector can be defined to filter on specific Ingress objects only.
 
 See [label-selectors](https://kubernetes.io/docs/concepts/overview/working-with-objects/labels/#label-selectors) for details.
 
+### `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 2 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`).
+
+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.
 
 ## Annotations
 
-Annotations can be used on containers to override default behaviour for the whole Ingress resource:
+### General annotations
 
-- `traefik.frontend.rule.type: PathPrefixStrip`  
-    Override the default frontend rule type. Default: `PathPrefix`.
-- `traefik.frontend.priority: "3"`
-    Override the default frontend rule priority.

-- `traefik.backend.loadbalancer.method=drr`  
-    Override the default `wrr` load balancer algorithm
-- `traefik.backend.loadbalancer.stickiness=true`      
-    Enable backend sticky sessions
-- `traefik.backend.loadbalancer.stickiness.cookieName=NAME`      
-    Manually set the cookie name for sticky sessions
-- `traefik.backend.loadbalancer.sticky=true`      
-    Enable backend sticky sessions (DEPRECATED)
 
-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).
+<1> `traefik.ingress.kubernetes.io/error-pages` example:
 
-Additionally, an annotation can be used on Kubernetes services to set the [circuit breaker expression](/basics/#backends) for a backend.
+```yaml
+foo:
+  status:
+  - "404"
+  backend: bar
+  query: /bar
+fii:
+  status:
+  - "503"
+  - "500"
+  backend: bar
+  query: /bir
+```
 
-- `traefik.backend.circuitbreaker: <expression>`  
-    Set the circuit breaker expression for the backend. Default: `nil`.
+<2> `traefik.ingress.kubernetes.io/rate-limit` example:
 
-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:
+```yaml
+extractorfunc: client.ip
+rateset:
+  bar:
+    period: 3s
+    average: 6
+    burst: 9
+  foo:
+    period: 6s
+    average: 12
+    burst: 18
+```
 
-- `ingress.kubernetes.io/whitelist-source-range: "1.2.3.0/24, fe80::/16"`
+<3> `traefik.ingress.kubernetes.io/buffering` example:
 
-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.
+```yaml
+maxrequestbodybytes: 10485760
+memrequestbodybytes: 2097153
+maxresponsebodybytes: 10485761
+memresponsebodybytes: 2097152
+retryexpression: IsNetworkError() && Attempts() <= 2
+```
 
+<4> `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.
+
+<5> `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).
+
+<6> `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).

 ### 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 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`: `mysecret`  
-    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 Træfik'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.

+### 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.

+### 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.
+
+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
+
+Træfik 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 Træfik.
+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 Træfik 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>
+```
+
+#### 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]
+  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
+
+As the web provider is deprecated, you can handle the `auth` option like this:
+
+```toml
+defaultEntryPoints = ["http"]
+
+[entryPoints]
+  [entryPoints.http]
+  address = ":80"
+
+ [entryPoints.foo]
+   address=":8080"

-
-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

-```
-
-To write the logs into a logfile specify the `filePath`.
-```toml
-[accessLog]

-For dynamic providers, the corresponding template file needs to be customized accordingly and referenced in the Traefik configuration.
 
+## 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.rateset1]
+            period = "10s"
+            average = 100
+            burst = 200
+          [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 5 requests every 3 seconds is allowed and an average of 100 requests every 10 seconds.  
+These can "burst" up to 10 and 200 in each period respectively.
+
+## Buffering
+
+In some cases request/buffering can be enabled for a specific backend.
+By enabling this, Træfik 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]

+## 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 write JSON format logs, specify `json` as the format:
+```toml
+[traefikLog]
+  filePath = "/path/to/traefik.log"
+  format   = "json"
+```
+
+
+Deprecated way (before 1.4):

+# In case both traefikLogsFile and traefikLog.filePath are specified, the latter will take precedence.
+# Optional
+#

+
+To customize the log level:
+```toml
+# Log level
+#
+# Optional
+# Default: "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 log file 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"
+```
+
+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"
+
+  [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

+
+
+!!! warning
+    Even if you have authentication configured on entry point, the `/ping` path of the api is excluded from authentication.
+
+## Examples
+
+The `/ping` health-check URL is enabled with the command-line `--ping` or config file option `[ping]`.
+Thus, if you have a regular path for `/foo` and an entrypoint on `:80`, you would access them as follows:
+
+* Regular path: `http://hostname:80/foo`
+* Admin panel: `http://hostname:8080/`
+* Ping URL: `http://hostname:8080/ping`
+
+However, for security reasons, you may want to be able to expose the `/ping` health-check URL to outside health-checkers, e.g. an Internet service or cloud load-balancer, _without_ exposing your administration panel's port.
+In many environments, the security staff may not _allow_ you to expose it.
+
+You have two options:
+
+* Enable `/ping` on a regular entry point
+* Enable `/ping` on a dedicated port
+
+### Ping health check on a regular entry point
+
+To proxy `/ping` from a regular entry point to the administration one without exposing the panel, do the following:
+
+```toml
+defaultEntryPoints = ["http"]
+
+[entryPoints]
+  [entryPoints.http]
+  address = ":80"
+
+[ping]
+entryPoint = "http"
+
+```
+
+The above link `ping` on the `http` entry point and then expose it on port `80`
+
+### Enable ping health check on dedicated port
+
+If you do not want to or cannot expose the health-check on a regular entry point - e.g. your security rules do not allow it, or you have a conflicting path - then you can enable health-check on its own entry point.
+Use the following configuration:
+
+```toml
+defaultEntryPoints = ["http"]
+
+[entryPoints]
+  [entryPoints.http]
+  address = ":80"
+  [entryPoints.ping]
+  address = ":8082"
+
+[ping]
+entryPoint = "ping"
+```
+
+The above is similar to the previous example, but instead of enabling `/ping` on the _default_ entry point, we enable it on a _dedicated_ entry point.
+
+In the above example, you would access a regular path and health-check as follows:
+
+* Regular path: `http://hostname:80/foo`
+* Ping URL: `http://hostname:8082/ping`
+
+Note the dedicated port `:8082` for `/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 this entry point.
+
+### Using ping for external Load-balancer rotation health check
+
+If you are running traefik behind a external Load-balancer, and want to configure rotation health check on the Load-balancer to take a traefik instance out of rotation gracefully, you can configure [lifecycle.requestAcceptGraceTimeout](/configuration/commons.md#life-cycle) and the ping endpoint will return `503` response on traefik server termination, so that the Load-balancer can take the terminating traefik instance out of rotation, before it stops responding.

+
+## Jaeger
+
+```toml
+# Tracing definition
+[tracing]
+  # Backend name used to send tracing data
+  #
+  # Default: "jaeger"
+  #
+  backend = "jaeger"
+
+  # Service name used in Jaeger backend
+  #
+  # Default: "traefik"
+  #
+  serviceName = "traefik"
+    
+  # Span name limit allows for name truncation in case of very long Frontend/Backend names
+  # This can prevent certain tracing providers to drop traces that exceed their length limits
+  #
+  # Default: 0 - no truncation will occur
+  # 
+  spanNameLimit = 0
+
+  [tracing.jaeger]
+    # Sampling Server URL is the address of jaeger-agent's HTTP sampling server
+    #
+    # Default: "http://localhost:5778/sampling"
+    #
+    samplingServerURL = "http://localhost:5778/sampling"
+
+    # Sampling Type specifies the type of the sampler: const, probabilistic, rateLimiting
+    #
+    # Default: "const"
+    #
+    samplingType = "const"
+
+    # Sampling Param is a value passed to the sampler.
+    # Valid values for Param field are:
+    #   - for "const" sampler, 0 or 1 for always false/true respectively
+    #   - for "probabilistic" sampler, a probability between 0 and 1
+    #   - for "rateLimiting" sampler, the number of spans per second
+    #
+    # Default: 1.0
+    #
+    samplingParam = 1.0
+
+    # Local Agent Host Port instructs reporter to send spans to jaeger-agent at this address
+    #
+    # Default: "127.0.0.1:6831"
+    #
+    localAgentHostPort = "127.0.0.1:6831"
+```
+
+!!! warning
+    Træfik is only able to send data over compact thrift protocol to the [Jaeger agent](https://www.jaegertracing.io/docs/deployment/#agent).
+
+## Zipkin
+
+```toml
+# Tracing definition
+[tracing]
+  # Backend name used to send tracing data
+  #
+  # Default: "jaeger"
+  #
+  backend = "zipkin"
+
+  # Service name used in Zipkin backend
+  #
+  # Default: "traefik"
+  #
+  serviceName = "traefik"
+    
+  # Span name limit allows for name truncation in case of very long Frontend/Backend names
+  # This can prevent certain tracing providers to drop traces that exceed their length limits
+  #
+  # Default: 0 - no truncation will occur
+  # 
+  spanNameLimit = 150
+
+  [tracing.zipkin]
+    # Zipking HTTP endpoint used to send data
+    #
+    # Default: "http://localhost:9411/api/v1/spans"
+    #
+    httpEndpoint = "http://localhost:9411/api/v1/spans"
+
+    # Enable Zipkin debug
+    #
+    # Default: false
+    #
+    debug = false
+
+    # Use ZipKin SameSpan RPC style traces
+    #
+    # Default: false
+    #
+    sameSpan = false
+
+    # Use ZipKin 128 bit root span IDs
+    #
+    # Default: true
+    #
+    id128Bit = true
+```
+
+## DataDog
+
+```toml
+# Tracing definition
+[tracing]
+  # Backend name used to send tracing data
+  #
+  # Default: "jaeger"
+  #
+  backend = "datadog"
+
+  # Service name used in DataDog backend
+  #
+  # Default: "traefik"
+  #
+  serviceName = "traefik"
+  
+  # Span name limit allows for name truncation in case of very long Frontend/Backend names
+  # This can prevent certain tracing providers to drop traces that exceed their length limits
+  #
+  # Default: 0 - no truncation will occur
+  # 
+  spanNameLimit = 100
+
+  [tracing.datadog]
+    # Local Agent Host Port instructs reporter to send spans to datadog-tracing-agent at this address
+    #
+    # Default: "127.0.0.1:8126"
+    #
+    localAgentHostPort = "127.0.0.1:8126"
+
+    # Enable DataDog debug
