-:construction: As stated in the [1.7 release note](https://blog.containo.us/traefik-1-7-yet-another-slice-of-awesomeness-2a9c99737889#782d), a significant update is in progress on the [master](https://github.com/containous/traefik/tree/master) branch. This branch will remain in constant evolution and prone to change with little notice, so use it for test purposes only.
+:warning: Please be aware that the old configurations for Traefik v1.X are NOT compatible with the v2.X config as of now. If you're running v2, please ensure you are using a [v2 configuration](https://docs.traefik.io/).

 ## Quickstart
 
 To get your hands on Traefik, you can use the [5-Minute Quickstart](http://docs.traefik.io/#the-traefik-quickstart-using-docker) in our documentation (you will need Docker).
 
-Alternatively, if you don't want to install anything on your computer, you can try Traefik online in this great [Katacoda tutorial](https://www.katacoda.com/courses/traefik/deploy-load-balancer) that shows how to load balance requests between multiple Docker containers. 
-
-If you are looking for a more comprehensive and real use-case example, you can also check [Play-With-Docker](http://training.play-with-docker.com/traefik-load-balancing/) to see how to load balance between multiple nodes.

 !!! tip "Source Directory"
- 
+
     It is recommended that you clone Traefik into the `~/go/src/github.com/containous/traefik` directory.
     This is the official golang workspace hierarchy that will allow dependencies to be properly resolved.
 
 !!! note "Environment"
 
     Set your `GOPATH` and `PATH` variable to be set to `~/go` via:
-    
+
     ```bash
     export GOPATH=~/go
     export PATH=$PATH:$GOPATH/bin
     ```
- 
+
     For convenience, add `GOPATH` and `PATH` to your `.bashrc` or `.bash_profile`
-    
+
     Verify your environment is setup properly by running `$ go env`.

-### Setting up dependency management
-
-The [dep](https://github.com/golang/dep) command is not required for building;
-however, it is necessary if you need to update the dependencies (i.e., add, update, or remove third-party packages).
-
-You need [dep](https://github.com/golang/dep) >= 0.5.0.
-
-If you want to add a dependency, use `dep ensure -add` to have [dep](https://github.com/golang/dep) put it into the vendor folder and update the dep manifest/lock files (`Gopkg.toml` and `Gopkg.lock`, respectively).
-
-A following `make dep-prune` run should be triggered to trim down the size of the vendor folder.
-The final result must be committed into VCS.

+There are three different, **mutually exclusive** (e.g. you can use only one at the same time), ways to define static configuration options in Traefik:

+1. In a configuration file

-If you don't provide a value for a given option, default values apply.
+These ways are evaluated in the order listed above.
 
-!!! important "Precedence Order"
-
-    The following precedence order applies for configuration options: key-value > command-line > configuration file.
+If no value was provided for a given option, a default value applies.
+Moreover, if an option has sub-options, and any of these sub-options is not specified, a default value will apply as well.
     
-    It means that arguments override configuration file, and key-value store overrides arguments.
-    
-!!! important "Default Values"
-
-    Some root options are enablers: they set default values for all their children. 
-    
-    For example, the `--providers.docker` option enables the docker provider.
-    Once positioned, this option sets (and resets) all the default values under the root `providers.docker`.
-    If you define child options using a lesser precedence configuration source, they will be overwritten by the default values.  
+For example, the `--providers.docker` option is enough by itself to enable the docker provider, even though sub-options like `--providers.docker.endpoint` exist.
+Once positioned, this option sets (and resets) all the default values of the sub-options of `--providers.docker`.

-Use the `TLS-ALPN-01` challenge to generate and renew ACME certificates by provisioning a TLS certificate.
-
-As described on the Let's Encrypt [community forum](https://community.letsencrypt.org/t/support-for-ports-other-than-80-and-443/3419/72),
-when using the `TLS-ALPN-01` challenge, Traefik must be reachable by Let's Encrypt through port 443.
-
-??? example "Configuring the `tlsChallenge`"
-
-    ```toml
-    [acme]
-       [acme.tlsChallenge]
-    ```
-    
-### `httpChallenge`
-
-Use the `HTTP-01` challenge to generate and renew ACME certificates by provisioning an HTTP resource under a well-known URI.
-
-As described on the Let's Encrypt [community forum](https://community.letsencrypt.org/t/support-for-ports-other-than-80-and-443/3419/72),
-when using the `HTTP-01` challenge, `acme.httpChallenge.entryPoint` must be reachable by Let's Encrypt through port 80.
-
-??? example "Using an EntryPoint Called http for the `httpChallenge`"
-
-    ```toml
-    [acme]
-       # ...
-       [acme.httpChallenge]
-          entryPoint = "http"
-    ```
-
-!!! note
-    Redirection is fully compatible with the `HTTP-01` challenge.
-
-### `dnsChallenge`
-
-Use the `DNS-01` challenge to generate and renew ACME certificates by provisioning a DNS record.
-
-??? example "Configuring a `dnsChallenge` with the DigitalOcean Provider"
-
-    ```toml
-    [acme]
-       # ...
-       [acme.dnsChallenge]
-          provider = "digitalocean"
-          delayBeforeCheck = 0
-    # ...
-    ```
-
-    !!! important
-        A `provider` is mandatory.
-
-#### `providers`
- 
-Here is a list of supported `providers`, that can automate the DNS verification,
-along with the required environment variables and their [wildcard & root domain support](#wildcard-domains).
-Do not hesitate to complete it.

-
-!!! note "`delayBeforeCheck`"
-    By default, the `provider` verifies the TXT record _before_ letting ACME verify.
-    You can delay this operation by specifying a delay (in seconds) with `delayBeforeCheck` (value must be greater than zero).
-    This option is useful when internal networks block external DNS queries.
-
-#### `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"]
-```
-
-#### Wildcard Domains
-
-[ACME V2](https://community.letsencrypt.org/t/acme-v2-and-wildcard-certificate-support-is-live/55579) supports wildcard certificates.
-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](#dnschallenge).
-
-```toml
-[acme]
-   # ...
-   [[acme.domains]]
-      main = "*.local1.com"
-      sans = ["local1.com"]
-
-# ...
-```
-
-!!! note "Double Wildcard Certificates"
-    It is not possible to request a double wildcard certificate for a domain (for example `*.*.local.com`).
-
-Due to an 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.
-Even though this behavior 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 given time (TTL) and this TTL can be greater than 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 [Supported `provider` table](#providers) indicates if they allow generating certificates for a wildcard domain and its root domain.
-
-## Known Domains, SANs
-
-You can set SANs (alternative domains) for each main domain.
-Every domain must have A/AAAA records pointing to Traefik.
-Each domain & SAN will lead to a certificate request.
-
-```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"]
-# ...
-```
-
-!!! important
-    The certificates for the domains listed in `acme.domains` are negotiated at Traefik startup only.
-
-!!! note
-    Wildcard certificates can only be verified through a `DNS-01` challenge.
-
-## `caServer`
-
-??? example "Using the Let's Encrypt staging server"
-
-    ```toml
-    [acme]
-       # ...
-       caServer = "https://acme-staging-v02.api.letsencrypt.org/directory"
-       # ...
-    ```
-
-## `onHostRule`
-
-Enable certificate generation on [routers](../routing/routers/index.md) `Host` & `HostSNI` rules.
-
-This will request a certificate from Let's Encrypt for each router with a Host rule.
-
-```toml
-[acme]
-   # ...
-   onHostRule = true
-   # ...
-```
-
-!!! note "Multiple Hosts in a Rule"
-    The rule `Host(test1.traefik.io,test2.traefik.io)` will request a certificate with the 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](#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
-
-### In a File
-
-ACME certificates can be stored in a JSON file that needs to have a `600` file mode .
-
-In Docker you can mount either 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
-    For concurrency reason, this file cannot be shared across multiple instances of Traefik. Use a key value store entry instead.
-
-### In a a Key Value Store Entry
-
-ACME certificates can be stored in a key-value store entry.
-
-```toml
-storage = "traefik/acme/account"
-```
-
-!!! note "Storage Size"
-
-    Because key-value stores have limited entry size, the certificates list is compressed _before_ it is saved.
-    For example, it is possible to store up to _approximately_ 100 ACME certificates in Consul.
-
-## Fallbacks
-
-If Let's Encrypt is not reachable, the following certificates will apply:
-
-  1. Previously generated ACME certificates (before downtime)
-  1. Expired ACME certificates
-  1. Provided certificates
-
-!!! note
-    For new (sub)domains which need Let's Encrypt authentication, the default Traefik certificate will be used until Traefik is restarted.

-# HTTPS & TLS
-
-Traefik supports HTTPS & TLS, and is able to accept new certificates / updates over time (without being restarted).
-TLS is enabled at the [router](../routing/routers/index.md) level, but some options are configured in dedicated sections (`tlsOptions` & `tlsStores`) described in this section.
-
-## Configuration Example
-
-??? example "Configuring a Default Certificate"
-
-    ```toml
-    [tlsStores]
-     [tlsStores.default]
-       [tlsStores.default.defaultCertificate]
-         certFile = "path/to/cert.crt"
-         keyFile  = "path/to/cert.key"
-    ```
-
-??? example "Configuring a Minimum TLS Version"
-
-    ```toml
-    [tlsOptions]
-      [tlsOptions.default]
-        minVersion = "VersionTLS12"
-    ```
-
-??? example "Defining Certificates"
-
-    ```toml
-    [[tls]]
-      [tls.certificate]
-         certFile = "/path/to/domain.cert"
-         keyFile = "/path/to/domain.key"
-
-    [[tls]]
-      [tls.certificate]
-         certFile = "/path/to/other-domain.cert"
-         keyFile = "/path/to/other-domain.key"
-    ```
-
-!!! important "File Provider Only"
-    
-    In the above example, we've used the [file provider](../providers/file.md) to handle the TLS configuration (tlsStores, tlsOptions, and TLS certificates).
-    In its current alpha version, it is the only available method to configure these elements.
-    Of course, these options are hot reloaded and can be updated at runtime (they belong to the [dynamic configuration](../getting-started/configuration-overview.md)).
-
-## Configuration Options
-
-### Dynamic Certificates
-
-To add / remove TLS certificates while Traefik is running, the [file provider](../providers/file.md) supports Dynamic TLS certificates in its `[[tls]]` section.
-
-!!! example "Defining Certificates"
-
-    ```toml
-    [[tls]]
-      stores = ["default"]
-      [tls.certificate]
-         certFile = "/path/to/domain.cert"
-         keyFile = "/path/to/domain.key"
-
-    [[tls]]
-      stores = ["default"]
-      [tls.certificate]
-         certFile = "/path/to/other-domain.cert"
-         keyFile = "/path/to/other-domain.key"
-    ```
-
-    ??? note "Stores"
-
-        During the alpha version, the stores option will be ignored and be automatically set to ["default"].
-
-### Mutual Authentication
-
-Traefik supports both optional and non optional (defaut value) mutual authentication.
-
-- When `optional = false`, Traefik accepts connections only from client presenting a certificate signed by a CA listed in `ClientCA.files`.
-- When `optional = true`, Traefik authorizes connections from client presenting a certificate signed by an unknown CA.
-
-!!! example "Non Optional Mutual Authentication"
-
-    In the following example, both `snitest.com` and `snitest.org` will require client certificates.
-
-    ```toml
-    [tlsOptions]
-       [tlsOptions.default]
-          [tlsOptions.default.ClientCA]
-            files = ["tests/clientca1.crt", "tests/clientca2.crt"]
-            optional = false
-    ```
-
-    ??? note "ClientCA.files"
-
-        You can use a file per `CA:s`, or a single file containing multiple `CA:s` (in `PEM` format).
-
-        `ClientCA.files` is not optional: every client will have to present a valid certificate. (This requirement will apply to every server certificate declared in the entrypoint.)
-
-### Minimum TLS Version
-
-!!! example "Min TLS version & [cipherSuites](https://godoc.org/crypto/tls#pkg-constants)"
-
-    ```toml
-    [tlsOptions]
-      [tlsOptions.default]
-          minVersion = "VersionTLS12"
-          cipherSuites = [
-            "TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256",
-            "TLS_RSA_WITH_AES_256_GCM_SHA384"
-          ]
-    ```
-
-### Strict SNI Checking
-
-With strict SNI checking, Traefik won't allow connections without a matching certificate.
-
-!!! example "Strict SNI"
-
-    ```toml
-    [tlsOptions]
-      [tlsOptions.default]
-        sniStrict = true
-    ```
-
-### Default Certificate
-
-Traefik can use a default certificate for connections without a SNI, or without a matching domain.
-
-If no default certificate is provided, Traefik generates and uses a self-signed certificate.
-
-!!! example "Setting a Default Certificate"
-
-    ```toml
-    [tlsStores]
-     [tlsStores.default]
-       [tlsStores.default.defaultCertificate]
-         certFile = "path/to/cert.crt"
-         keyFile  = "path/to/cert.key"
-    ```
-
-    ??? note "Only One Default Certificate"
-
-        There can only be one `defaultCertificate` per tlsOptions.
-
-    ??? note "Default TLS Store"
-
-        During the alpha version, there is only one globally available TLS Store (`default`).

+As described on the Let's Encrypt [community forum](https://community.letsencrypt.org/t/support-for-ports-other-than-80-and-443/3419/72),
+when using the `TLS-ALPN-01` challenge, Traefik must be reachable by Let's Encrypt through port 443.
+
+??? example "Configuring the `tlsChallenge`"
+
+    ```toml tab="File (TOML)"
+    [certificatesResolvers.sample.acme]
+      # ...
+      [certificatesResolvers.sample.acme.tlsChallenge]
+    ```
+

+    
+    ```bash tab="CLI"
+    # ...
+    --certificatesResolvers.sample.acme.tlsChallenge=true
+    ```
+
+### `httpChallenge`
+
+Use the `HTTP-01` challenge to generate and renew ACME certificates by provisioning an HTTP resource under a well-known URI.
+
+As described on the Let's Encrypt [community forum](https://community.letsencrypt.org/t/support-for-ports-other-than-80-and-443/3419/72),
+when using the `HTTP-01` challenge, `certificatesResolvers.sample.acme.httpChallenge.entryPoint` must be reachable by Let's Encrypt through port 80.
+
+??? example "Using an EntryPoint Called http for the `httpChallenge`"
+
+    ```toml tab="File (TOML)"
+    [entryPoints]
+      [entryPoints.web]
+        address = ":80"
+      
+      [entryPoints.web-secure]
+        address = ":443"
+    
+    [certificatesResolvers.sample.acme]

+      [certificatesResolvers.sample.acme.httpChallenge]
+        entryPoint = "web"
+    ```
+
+    ```yaml tab="File (YAML)"
+    entryPoints:
+      web:
+        address: ":80"
+

+    --entryPoints.websecure.address=":443"
+    # ...
+    --certificatesResolvers.sample.acme.httpChallenge.entryPoint=web
+    ```
+
+!!! info ""
+    Redirection is fully compatible with the `HTTP-01` challenge.
+
+### `dnsChallenge`
+
+Use the `DNS-01` challenge to generate and renew ACME certificates by provisioning a DNS record.
+
+??? example "Configuring a `dnsChallenge` with the DigitalOcean Provider"
+
+    ```toml tab="File (TOML)"
+    [certificatesResolvers.sample.acme]
+      # ...
+      [certificatesResolvers.sample.acme.dnsChallenge]
+        provider = "digitalocean"
+        delayBeforeCheck = 0
+    # ...
+    ```
+    
+    ```yaml tab="File (YAML)"
+    certificatesResolvers:
+      sample:
+        acme:
+          # ...
+          dnsChallenge:
+            provider: digitalocean
+            delayBeforeCheck: 0
+        # ...
+    ```
+    
+    ```bash tab="CLI"
+    # ...
+    --certificatesResolvers.sample.acme.dnsChallenge.provider=digitalocean
+    --certificatesResolvers.sample.acme.dnsChallenge.delayBeforeCheck=0
+    # ...
+    ```
+
+    !!! important
+        A `provider` is mandatory.
+
+#### `providers`
+ 
+Here is a list of supported `providers`, that can automate the DNS verification,
+along with the required environment variables and their [wildcard & root domain support](#wildcard-domains).
+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`.

+[^4]: `docker stack` remark: there is no way to support terminal attached to container when deploying with `docker stack`, so you might need to run container with `docker run -it` to generate certificates using `manual` provider.
+
+!!! info "`delayBeforeCheck`"
+    By default, the `provider` verifies the TXT record _before_ letting ACME verify.
+    You can delay this operation by specifying a delay (in seconds) with `delayBeforeCheck` (value must be greater than zero).
+    This option is useful when internal networks block external DNS queries.
+
+#### `resolvers`
+
+Use custom DNS servers to resolve the FQDN authority.
+
+```toml tab="File (TOML)"
+[certificatesResolvers.sample.acme]
+  # ...
+  [certificatesResolvers.sample.acme.dnsChallenge]
+    # ...
+    resolvers = ["1.1.1.1:53", "8.8.8.8:53"]
+```
+
+```yaml tab="File (YAML)"
+certificatesResolvers:
+  sample:
+    acme:
+      # ...
+      dnsChallenge:
+        # ...
+        resolvers:
+          - "1.1.1.1:53"
+          - "8.8.8.8:53"
+```
+
+```bash tab="CLI"
+# ...
+--certificatesResolvers.sample.acme.dnsChallenge.resolvers:="1.1.1.1:53,8.8.8.8:53"
+```
+
+#### Wildcard Domains
+
+[ACME V2](https://community.letsencrypt.org/t/acme-v2-and-wildcard-certificate-support-is-live/55579) supports wildcard certificates.
+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](#dnschallenge).
+
+## `caServer`
+
+??? example "Using the Let's Encrypt staging server"
+
+    ```toml tab="File (TOML)"
+    [certificatesResolvers.sample.acme]
+      # ...
+      caServer = "https://acme-staging-v02.api.letsencrypt.org/directory"
+      # ...
+    ```
+    
+    ```yaml tab="File (YAML)"
+    certificatesResolvers:
+      sample:
+        acme:
+          # ...
+          caServer: https://acme-staging-v02.api.letsencrypt.org/directory
+          # ...
+    ```
+
+    ```bash tab="CLI"
+    # ...
+    --certificatesResolvers.sample.acme.caServer="https://acme-staging-v02.api.letsencrypt.org/directory"
+    # ...
+    ```
+
+## `storage`
+
+The `storage` option sets the location where your ACME certificates are saved to.
+
+```toml tab="File (TOML)"
+[certificatesResolvers.sample.acme]
+  # ...
+  storage = "acme.json"
+  # ...
+```
+
+```yaml tab="File (YAML)"
+certificatesResolvers:
+  sample:
+    acme:
+      # ...
+      storage: acme.json
+      # ...
+```
+
+```bash tab="CLI"
+# ...
+--certificatesResolvers.sample.acme.storage=acme.json
+# ...
+```
+
+The value can refer to some kinds of storage:
+
+- a JSON file
+
+### In a File
+
+ACME certificates can be stored in a JSON file that needs to have a `600` file mode .
+
+In Docker you can mount either 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
+    For concurrency reason, this file cannot be shared across multiple instances of Traefik. Use a key value store entry instead.
+
+## Fallback
+
+If Let's Encrypt is not reachable, the following certificates will apply:
+
+  1. Previously generated ACME certificates (before downtime)
+  1. Expired ACME certificates
+  1. Provided certificates
+
+!!! important
+    For new (sub)domains which need Let's Encrypt authentication, the default Traefik certificate will be used until Traefik is restarted.

+# HTTPS & TLS
+
+Overview
+{: .subtitle }
+
+Traefik supports HTTPS & TLS, which concerns roughly two parts of the configuration:
+routers, and the TLS connection (and its underlying certificates).
+
+When a router has to handle HTTPS traffic,
+it should be specified with a `tls` field of the router definition.
+See the TLS section of the [routers documentation](../routing/routers/index.md#tls).
+
+The next sections of this documentation explain how to configure the TLS connection itself.
+That is to say, how to obtain [TLS certificates](./tls.md#certificates-definition):
+either through a definition in the dynamic configuration, or through [Let's Encrypt](./acme.md) (ACME).
+And how to configure [TLS options](./tls.md#tls-options), and [certificates stores](./tls.md#certificates-stores).

+
+## Certificates Definition
+
+### Automated
+
+See the [Let's Encrypt](./acme.md) page.
+
+### User defined
+
+To add / remove TLS certificates, even when Traefik is already running, their definition can be added to the [dynamic configuration](../getting-started/configuration-overview.md), in the `[[tls.certificates]]` section:
+
+```toml tab="File (TOML)"
+# Dynamic configuration
+
+[[tls.certificates]]
+  certFile = "/path/to/domain.cert"
+  keyFile = "/path/to/domain.key"
+
+[[tls.certificates]]
+  certFile = "/path/to/other-domain.cert"
+  keyFile = "/path/to/other-domain.key"
+```
+
+```yaml tab="File (YAML)"
+# Dynamic configuration
+
+tls:
+  certificates:
+    - certFile: /path/to/domain.cert
+      keyFile: /path/to/domain.key
+    - certFile: /path/to/other-domain.cert
+      keyFile: /path/to/other-domain.key
+```
+
+!!! important "Restriction"
+
+    In the above example, we've used the [file provider](../providers/file.md) to handle these definitions.
+    It is the only available method to configure the certificates (as well as the options and the stores).
+    However, in [Kubernetes](../providers/kubernetes-crd.md), the certificates can and must be provided by [secrets](../routing/providers/kubernetes-crd.md#tls). 
+
+## Certificates Stores
+
+In Traefik, certificates are grouped together in certificates stores, which are defined as such:
+
+```toml tab="File (TOML)"
+# Dynamic configuration
+
+[tls.stores]
+  [tls.stores.default]
+```
+
+```yaml tab="File (YAML)"
+# Dynamic configuration
+
+tls:
+  stores:
+    default: {}
+```
+
+!!! important "Restriction"
+
+    Any store definition other than the default one (named `default`) will be ignored,
+    and there is thefore only one globally available TLS store.
+
+In the `tls.certificates` section, a list of stores can then be specified to indicate where the certificates should be stored:
+
+```toml tab="File (TOML)"
+# Dynamic configuration
+
+[[tls.certificates]]
+  certFile = "/path/to/domain.cert"
+  keyFile = "/path/to/domain.key"
+  stores = ["default"]
+
+[[tls.certificates]]
+  # Note that since no store is defined,
+  # the certificate below will be stored in the `default` store.
+  certFile = "/path/to/other-domain.cert"
+  keyFile = "/path/to/other-domain.key"
+```
+
+```yaml tab="File (YAML)"
+# Dynamic configuration
+
+tls:
+  certificates:
+    - certFile: /path/to/domain.cert
+      keyFile: /path/to/domain.key
+      stores:
+        - default
+    # Note that since no store is defined,
+    # the certificate below will be stored in the `default` store.
+    - certFile: /path/to/other-domain.cert
+      keyFile: /path/to/other-domain.key
+```
+
+!!! important "Restriction"
+
+    The `stores` list will actually be ignored and automatically set to `["default"]`.
+
+### Default Certificate
+
+Traefik can use a default certificate for connections without a SNI, or without a matching domain.
+This default certificate should be defined in a TLS store:
+
+```toml tab="File (TOML)"
+# Dynamic configuration
+
+[tls.stores]
+  [tls.stores.default]
+    [tls.stores.default.defaultCertificate]
+      certFile = "path/to/cert.crt"
+      keyFile  = "path/to/cert.key"
+```
+
+```yaml tab="File (YAML)"
+# Dynamic configuration
+
+tls:
+  stores:
+    default:
+      defaultCertificate:
+        certFile: path/to/cert.crt
+        keyFile: path/to/cert.key
+```
+
+If no default certificate is provided, Traefik generates and uses a self-signed certificate.
+
+## TLS Options
+
+The TLS options allow one to configure some parameters of the TLS connection.
+
+### Minimum TLS Version
+
+```toml tab="File (TOML)"
+# Dynamic configuration
+
+[tls.options]
+
+  [tls.options.default]
+    minVersion = "VersionTLS12"
+
+  [tls.options.mintls13]
+    minVersion = "VersionTLS13"
+```
+
+```yaml tab="File (YAML)"
+# Dynamic configuration
+
+tls:
+  options:
+    default:
+      minVersion: VersionTLS12
+
+    mintls13:
+      minVersion: VersionTLS13
+```
+
+```yaml tab="Kubernetes"
+apiVersion: traefik.containo.us/v1alpha1
+kind: TLSOption
+metadata:
+  name: default
+  namespace: default
+
+spec:
+  minVersion: VersionTLS12
+
+---
+apiVersion: traefik.containo.us/v1alpha1
+kind: TLSOption
+metadata:
+  name: mintls13
+  namespace: default
+
+spec:
+  minVersion: VersionTLS13
+```
+
+### Cipher Suites
+
+See [cipherSuites](https://godoc.org/crypto/tls#pkg-constants) for more information.
+
+```toml tab="File (TOML)"
+# Dynamic configuration
+
+[tls.options]
+  [tls.options.default]
+    cipherSuites = [
+      "TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256",
+      "TLS_RSA_WITH_AES_256_GCM_SHA384"
+    ]
+```
+
+```yaml tab="File (YAML)"
+# Dynamic configuration
+
+tls:
+  options:
+    default:
+      cipherSuites:
+        - TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256
+        - TLS_RSA_WITH_AES_256_GCM_SHA384
+```
+
+```yaml tab="Kubernetes"
+apiVersion: traefik.containo.us/v1alpha1
+kind: TLSOption
+metadata:
+  name: default
+  namespace: default
+
+spec:
+  cipherSuites:
+    - TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256
+    - TLS_RSA_WITH_AES_256_GCM_SHA384
+```
+
+!!! important "TLS 1.3"
+
+    Cipher suites defined for TLS 1.2 and below cannot be used in TLS 1.3, and vice versa. (<https://tools.ietf.org/html/rfc8446>)  
+    With TLS 1.3, the cipher suites are not configurable (all supported cipher suites are safe in this case).
+    <https://golang.org/doc/go1.12#tls_1_3>
+
+### Strict SNI Checking
+
+With strict SNI checking, Traefik won't allow connections from clients connections
+that do not specify a server_name extension.
+
+```toml tab="File (TOML)"
+# Dynamic configuration
+
+[tls.options]
+  [tls.options.default]
+    sniStrict = true
+```
+
+```yaml tab="File (YAML)"
+# Dynamic configuration
+
+tls:
+  options:
+    default:
+      sniStrict: true
+```
+
+```yaml tab="Kubernetes"
+apiVersion: traefik.containo.us/v1alpha1
+kind: TLSOption
+metadata:
+  name: default
+  namespace: default
+
+spec:
+  sniStrict: true
+```
+
+### Client Authentication (mTLS)
+
+Traefik supports mutual authentication, through the `clientAuth` section.
+
+For authentication policies that require verification of the client certificate, the certificate authority for the certificate should be set in `clientAuth.caFiles`.
+ 
+The `clientAuth.clientAuthType` option governs the behaviour as follows:
+
+- `NoClientCert`: disregards any client certificate.
+- `RequestClientCert`: asks for a certificate but proceeds anyway if none is provided.
+- `RequireAnyClientCert`: requires a certificate but does not verify if it is signed by a CA listed in `clientAuth.caFiles`.
+- `VerifyClientCertIfGiven`: if a certificate is provided, verifies if it is signed by a CA listed in `clientAuth.caFiles`. Otherwise proceeds without any certificate.
+- `RequireAndVerifyClientCert`: requires a certificate, which must be signed by a CA listed in `clientAuth.caFiles`. 
+
+```toml tab="File (TOML)"
+# Dynamic configuration
+
+[tls.options]
+  [tls.options.default]
+    [tls.options.default.clientAuth]
+      # in PEM format. each file can contain multiple CAs.
+      caFiles = ["tests/clientca1.crt", "tests/clientca2.crt"]
+      clientAuthType = "RequireAndVerifyClientCert"
+```
+
+```yaml tab="File (YAML)"
+# Dynamic configuration
+
+tls:
+  options:
+    default:
+      clientAuth:
+        # in PEM format. each file can contain multiple CAs.
+        caFiles:
+          - tests/clientca1.crt
+          - tests/clientca2.crt
+        clientAuthType: RequireAndVerifyClientCert
+```
+
+```yaml tab="Kubernetes"
+apiVersion: traefik.containo.us/v1alpha1
+kind: TLSOption
+metadata:
+  name: default
+  namespace: default
+
+spec:

+    secretNames:

+    In kubernetes, you need to reference a kubernetes service instead of a traefik service.
+
+### `query`
 
 The URL for the error page (hosted by `service`). You can use `{status}` in the query, that will be replaced by the received status code.

+
+### `sourceCriterion`
+ 
+SourceCriterion defines what criterion is used to group requests as originating from a common source.
+The precedence order is `ipStrategy`, then `requestHeaderName`, then `requestHost`.
+If none are set, the default is to use the `requestHost`.
+
+#### `sourceCriterion.ipStrategy`
+
+The `ipStrategy` option defines two parameters that sets how Traefik will determine the client IP: `depth`, and `excludedIPs`.
+
+##### `ipStrategy.depth`
+
+The `depth` option tells Traefik to use the `X-Forwarded-For` header and take the IP located at the `depth` position (starting from the right).
+
+- If `depth` is greater than the total number of IPs in `X-Forwarded-For`, then the client IP will be empty.
+- `depth` is ignored if its value is lesser than or equal to 0.
+    
+!!! example "Example of Depth & X-Forwarded-For"
+
+    If `depth` was equal to 2, and the request `X-Forwarded-For` header was `"10.0.0.1,11.0.0.1,12.0.0.1,13.0.0.1"` then the "real" client IP would be `"10.0.0.1"` (at depth 4) but the IP used as the criterion would be `"12.0.0.1"` (`depth=2`).
+
+    | `X-Forwarded-For`                       | `depth` | clientIP     |
+    |-----------------------------------------|---------|--------------|

 ## Configuration Options
 
-### sourceRange
+### `sourceRange`
 
 The `sourceRange` option sets the allowed IPs (or ranges of allowed IPs).
 
-### ipStrategy
+### `ipStrategy`
 
 The `ipStrategy` option defines two parameters that sets how Traefik will determine the client IP: `depth`, and `excludedIPs`.
 
-#### ipStrategy.depth 
+#### `ipStrategy.depth`
 
 The `depth` option tells Traefik to use the `X-Forwarded-For` header and take the IP located at the `depth` position (starting from the right).

-## Configuration Options
-
-### amount
-
-The `amount` option defines the maximum amount of allowed simultaneous connections.
-The middleware will return an `HTTP 429 Too Many Requests` if there are already `amount` requests in progress (based on the same `extractorfunc` strategy).
-
-### extractorfunc
-
-The `extractorfunc` defines the strategy used to categorize requests.
-
-The possible values are:
-
-- `request.host` categorizes requests based on the request host.
-- `client.ip` categorizes requests based on the client ip.
-- `request.header.ANY_HEADER` categorizes requests based on the provided `ANY_HEADER` value.

+## Provider Namespace
+
+When you declare a middleware, it lives in its provider namespace.
+For example, if you declare a middleware using a Docker label, under the hoods, it will reside in the docker provider namespace.
+
+If you use multiple providers and wish to reference a middleware declared in another provider
+(aka referencing a cross-provider middleware),
+then you'll have to append to the middleware name, the `@` separator, followed by the provider name.
+
+```text
+<resource-name>@<provider-name>
+```
+
+!!! important "Kubernetes Namespace"
+
+	As Kubernetes also has its own notion of namespace, one should not confuse the "provider namespace"
+with the "kubernetes namespace" of a resource when in the context of a cross-provider usage.
+In this case, since the definition of the middleware is not in kubernetes,
+specifying a "kubernetes namespace" when referring to the resource does not make any sense,
+and therefore this specification would be ignored even if present.

+
+### `sourceCriterion`
  
-The `extractorfunc` option defines the strategy used to categorize requests.
+SourceCriterion defines what criterion is used to group requests as originating from a common source.
+The precedence order is `ipStrategy`, then `requestHeaderName`, then `requestHost`.
+If none are set, the default is to use the request's remote address field (as an `ipStrategy`).
 
-The possible values are:
+#### `sourceCriterion.ipStrategy`
 
-- `request.host` categorizes requests based on the request host.
-- `client.ip` categorizes requests based on the client ip.
-- `request.header.ANY_HEADER` categorizes requests based on the provided `ANY_HEADER` value.
+The `ipStrategy` option defines two parameters that sets how Traefik will determine the client IP: `depth`, and `excludedIPs`.
 
-### ratelimit (multiple values)
+##### `ipStrategy.depth`
 
-You can combine multiple ratelimit. 
-The ratelimit will trigger with the first reached limit.
+The `depth` option tells Traefik to use the `X-Forwarded-For` header and take the IP located at the `depth` position (starting from the right).
 
-Each ratelimit has 3 options, `period`, `average`, and `burst`.
+- If `depth` is greater than the total number of IPs in `X-Forwarded-For`, then the client IP will be empty.
+- `depth` is ignored if its value is lesser than or equal to 0.
 
-The rate limit will allow an average of `average` requests every `period`, with a maximum of `burst` request on that period.
+!!! example "Example of Depth & X-Forwarded-For"
 
-!!! note "Period Format"
+    If `depth` was equal to 2, and the request `X-Forwarded-For` header was `"10.0.0.1,11.0.0.1,12.0.0.1,13.0.0.1"` then the "real" client IP would be `"10.0.0.1"` (at depth 4) but the IP used as the criterion would be `"12.0.0.1"` (`depth=2`).
 
-    Period is to be given in a format understood by [time.ParseDuration](https://golang.org/pkg/time/#ParseDuration).
+    | `X-Forwarded-For`                       | `depth` | clientIP     |

+# Migration Guide: From v1 to v2
+
+How to Migrate from Traefik v1 to Traefik v2.
+{: .subtitle }
+
+The version 2 of Traefik introduces a number of breaking changes, 
+which require one to update their configuration when they migrate from v1 to v2.
+The goal of this page is to recapitulate all of these changes, and in particular to give examples, 
+feature by feature, of how the configuration looked like in v1, and how it now looks like in v2.
+
+!!! info "Migration Helper"
+    
+    We created a tool to help during the migration: [traefik-migration-tool](https://github.com/containous/traefik-migration-tool)
+
+    This tool allows to:
+
+    - convert `Ingress` to Traefik `IngressRoute` resources.
+    - convert `acme.json` file from v1 to v2 format.
+    - migrate the static configuration contained in the file `traefik.toml` to a Traefik v2 file.
+
+## Frontends and Backends Are Dead... <br/>... Long Live Routers, Middlewares, and Services
+
+During the transition from v1 to v2, a number of internal pieces and components of Traefik were rewritten and reorganized.
+As such, the combination of core notions such as frontends and backends has been replaced with the combination of [routers](../routing/routers/index.md), [services](../routing/services/index.md), and [middlewares](../middlewares/overview.md).
+
+Typically, a router replaces a frontend, and a service assumes the role of a backend, with each router referring to a service.
+However, even though a backend was in charge of applying any desired modification on the fly to the incoming request,
+the router defers that responsibility to another component.
+Instead, a dedicated middleware is now defined for each kind of such modification.
+Then any router can refer to an instance of the wanted middleware.
+
+!!! example "One frontend with basic auth and one backend, become one router, one service, and one basic auth middleware."

+## TLS configuration is now dynamic, per router.
+
+TLS parameters used to be specified in the static configuration, as an entryPoint field.
+With Traefik v2, a new dynamic TLS section at the root contains all the desired TLS configurations.
+Then, a [router's TLS field](../routing/routers/index.md#tls) can refer to one of the [TLS configurations](../https/tls.md) defined at the root, hence defining the [TLS configuration](../https/tls.md) for that router.

+## HTTP to HTTPS Redirection is now configured on Routers
+
+Previously on Traefik v1, the redirection was applied on an entry point or on a frontend.
+With Traefik v2 it is applied on a [Router](../routing/routers/index.md). 
+
+To apply a redirection, one of the redirect middlewares, [RedirectRegex](../middlewares/redirectregex.md) or [RedirectScheme](../middlewares/redirectscheme.md), has to be configured and added to the router middlewares list.

+
+Traefik v2 retains OpenTracing support. The `backend` root option from the v1 is gone, you just have to set your [tracing configuration](../observability/tracing/overview.md).

+
+You need to activate the [API](../operations/dashboard.md#enabling-the-dashboard) to access the dashboard.
+As the dashboard access is now secured by default you can either:
+
+* define a  [specific router](../operations/api.md#configuration) with the `api@internal` service and one authentication middleware like the following example
+* or use the [unsecure](../operations/api.md#insecure) option of the API

+
+## Some Tips You Should Known
+
+* Different sources of static configuration (file, CLI flags, ...) cannot be [mixed](../getting-started/configuration-overview.md#the-static-configuration).
+* Now, configuration elements can be referenced between different providers by using the provider namespace notation: `@<provider>`.
+  For instance, a router named `myrouter` in a File Provider can refer to a service named `myservice` defined in Docker Provider with the following notation: `myservice@docker`.
+* Middlewares are applied in the same order as their declaration in router.
+* If you have any questions feel free to join our [community forum](https://community.containo.us).

 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`.

-## Configuration Options
+## Configuration
 
 ### General
 
 Traefik logs concern everything that happens to Traefik itself (startup, configuration, events, shutdown, and so on).
 
-#### filePath
+#### `filePath`
 
 By default, the logs are written to the standard output.
 You can configure a file path instead using the `filePath` option.
 
-#### format
+```toml tab="File (TOML)"
+# Writing Logs to a File
+[log]
+  filePath = "/path/to/traefik.log"
+```
+
+```yaml tab="File (YAML)"
+# Writing Logs to a File
+log:
+  filePath: "/path/to/traefik.log"
+```
+
+```bash tab="CLI"
+# Writing Logs to a File
+--log.filePath="/path/to/traefik.log"
+```
+
+#### `format`
 
 By default, the logs use a text format (`common`), but you can also ask for the `json` format in the `format` option.   
 
-#### logLevel
+```toml tab="File (TOML)"
+# Writing Logs to a File, in JSON
+[log]
+  filePath = "/path/to/log-file.log"
+  format = "json"
+```
 
-By default, the `logLevel` is set to `error`, but you can choose amongst `debug`, `panic`, `fatal`, `error`, `warn`, and `info`. 
+```yaml tab="File (YAML)"
+# Writing Logs to a File, in JSON

+# Writing Logs to a File, in JSON
+--log.filePath="/path/to/traefik.log"
+--log.format="json"
+```
+
+#### `level`
+
+By default, the `level` is set to `ERROR`. Alternative logging levels are `DEBUG`, `PANIC`, `FATAL`, `ERROR`, `WARN`, and `INFO`. 
+
+```toml tab="File (TOML)"

-# Tracing
-
-Visualize the Requests Flow
-{: .subtitle }
-
-The tracing system allows developers to visualize call flows in their infrastructure.
-
-Traefik uses OpenTracing, an open standard designed for distributed tracing.
-
-Traefik supports three tracing backends: Jaeger, Zipkin, DataDog, and Instana.
-
-## Configuration Reference
-
-??? example "With Jaeger" 
-
-    ```toml
-    # Tracing definition
-    [tracing]

-        
-      # 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

+# Tracing
+
+Visualize the Requests Flow
+{: .subtitle }
+
+The tracing system allows developers to visualize call flows in their infrastructure.
+
+Traefik uses OpenTracing, an open standard designed for distributed tracing.
+
+Traefik supports five tracing backends:
+
+- [Jaeger](./jaeger.md)
+- [Zipkin](./zipkin.md)
+- [Datadog](./datadog.md)
+- [Instana](./instana.md)
+- [Haystack](./haystack.md)
+
+## Configuration
+
+By default, Traefik uses Jaeger as tracing backend.
+
+To enable the tracing:
+
+```toml tab="File (TOML)"
+[tracing]
+```
+
+```yaml tab="File (YAML)"
+tracing: {}
+```
+
+```bash tab="CLI"
+--tracing=true
+```
+
+### Common Options
+
+#### `serviceName`
+
+_Required, Default="traefik"_
+
+Service name used in selected backend.
+
+```toml tab="File (TOML)"
+[tracing]
+  serviceName = "traefik"
+```
+
+```yaml tab="File (YAML)"
+tracing:
+  serviceName: traefik
+```
+
+```bash tab="CLI"
+--tracing.serviceName="traefik"
+```
+
+#### `spanNameLimit`
+
+_Required, Default=0_
+
+Span name limit allows for name truncation in case of very long names.
+This can prevent certain tracing providers to drop traces that exceed their length limits.
+
+`0` means no truncation will occur.
+
+```toml tab="File (TOML)"
+[tracing]
+  spanNameLimit = 150
+```
+
+```yaml tab="File (YAML)"
+tracing:
+  spanNameLimit: 150

+
+```bash tab="CLI"
+--tracing.spanNameLimit=150
