+
+In `v2.2.2` we introduced a new rule matcher (`HostSNI`) which was allowing to match the Server Name Indication at the router level.
+Since `v2.2.5` this rule has been removed, and you should not use it anymore.

+
+### File Provider
+

+
+In `v2.3`, the support of `IngressClass`, which is available since Kubernetes version `1.18`, has been introduced.

+# Plugins and Traefik Pilot
+
+Overview
+{: .subtitle}
+
+Traefik Pilot is a software-as-a-service (SaaS) platform that connects to Traefik to extend its capabilities.
+It does this through *plugins*, which are dynamically loaded components that enable new features.
+
+For example, Traefik plugins can add features to modify requests or headers, issue redirects, add authentication, and so on, providing similar functionality to Traefik [middlewares](https://docs.traefik.io/middlewares/overview/).
+
+Traefik Pilot can also monitor connected Traefik instances and issue alerts when one is not responding, or when it is subject to security vulnerabilities.
+
+!!! note "Availability"
+    Plugins are available for Traefik v2.3.0-rc1 and later.
+    
+!!! danger "Experimental Features"
+    Plugins can potentially modify the behavior of Traefik in unforeseen ways.
+    Exercise caution when adding new plugins to production Traefik instances.
+
+## Connecting to Traefik Pilot
+
+Plugins are available when a Traefik instance is connected to Traefik Pilot.
+
+To register a new instance and begin working with plugins, login or create an account at the [Traefik Pilot homepage](https://pilot.traefik.io) and choose **Register New Instance**.
+
+To complete the connection, Traefik Pilot will issue a token that must be added to your Traefik static configuration by following the instructions provided.
+
+!!! note "Enabling Alerts" 
+    Health and security alerts for registered Traefik instances can be enabled from the Preferences in your [Traefik Pilot Profile](https://pilot.traefik.io/profile).
+
+## Creating Plugins
+
+Traefik users can create their own plugins and contribute them to the Traefik Pilot catalog to share them with the community.
+
+Plugins are written in [Go](https://golang.org/) and their code is executed by an [embedded Go interpreter](https://github.com/containous/yaegi).
+There is no need to compile binaries and all plugins are 100% cross-platform.
+
+To learn more and see code for example Traefik plugins, please see the [developer documentation](https://github.com/containous/plugindemo).

+# Using Plugins
+
+Plugins are available to any instance of Traefik v2.3 or later that is [registered](overview.md#connecting-to-traefik-pilot) with Traefik Pilot.
+Plugins are hosted on GitHub, but you can browse plugins to add to your registered Traefik instances from the Traefik Pilot UI.
+
+!!! danger "Experimental Features"
+    Plugins can potentially modify the behavior of Traefik in unforeseen ways.
+    Exercise caution when adding new plugins to production Traefik instances.
+
+## Add a Plugin
+
+To add a new plugin to a Traefik instance, you must modify that instance's static configuration.
+The code to be added is provided by the Traefik Pilot UI when you choose **Install the Plugin**.
+
+In the example below, we add the [`blockpath`](http://github.com/containous/plugin-blockpath) and [`rewritebody`](https://github.com/containous/plugin-rewritebody) plugins:
+
+```toml tab="File (TOML)"
+[entryPoints]
+  [entryPoints.web]
+    address = ":80"
+
+[experimental]
+  [experimental.pilot]
+    token = "xxxxxxxxx"
+
+  [experimental.plugins]
+    [experimental.plugins.block]
+      modulename = "github.com/containous/plugin-blockpath"
+      version = "v0.1.2"
+    [experimental.plugins.rewrite]
+      modulename = "github.com/containous/plugin-rewritebody"
+      version = "v0.2.0"
+```
+
+```yaml tab="File (YAML)"
+entryPoints:
+  web:
+    address: :80
+

+  pilot:
+    token: xxxxxxxxx

+    rewrite:
+      modulename: github.com/containous/plugin-rewritebody
+      version: v0.2.0
+```
+
+```bash tab="CLI"
+--entryPoints.web.address=:80
+--experimental.pilot.token=xxxxxxxxx
+--experimental.plugins.block.modulename=github.com/containous/plugin-blockpath
+--experimental.plugins.block.version=v0.1.2
+--experimental.plugins.rewrite.modulename=github.com/containous/plugin-rewritebody
+--experimental.plugins.rewrite.version=v0.2.0
+```
+
+## Configuring Plugins
+
+Some plugins will need to be configured by adding a dynamic configuration.
+For the `bodyrewrite` plugin, for example:
+
+```yaml tab="Docker"
+labels:
+  - "traefik.http.middlewares.my-rewritebody.plugin.rewrite.rewrites[0].regex=example"

+# Traefik & ECS
+
+A Story of Labels & Elastic Containers
+{: .subtitle }
+
+Attach labels to your containers and let Traefik do the rest!
+
+## Routing Configuration
+
+!!! info "labels"
+    
+    - labels are case insensitive.
+    - The complete list of labels can be found [the reference page](../../reference/dynamic-configuration/ecs.md)
+
+### General
+
+Traefik creates, for each elastic service, a corresponding [service](../services/index.md) and [router](../routers/index.md).
+
+The Service automatically gets a server per elastic container, and the router gets a default rule attached to it, based on the service name.
+
+### Routers
+
+To update the configuration of the Router automatically attached to the service, add labels starting with `traefik.routers.{name-of-your-choice}.` and followed by the option you want to change.
+
+For example, to change the rule, you could add the label ```traefik.http.routers.my-service.rule=Host(`example.com`)```.
+
+!!! warning "The character `@` is not authorized in the router name `<router_name>`."
+
+??? info "`traefik.http.routers.<router_name>.rule`"
+    
+    See [rule](../routers/index.md#rule) for more information.

+
+### Middleware
+
+You can declare pieces of middleware using labels starting with `traefik.http.middlewares.{name-of-your-choice}.`, followed by the middleware type/options.
+
+For example, to declare a middleware [`redirectscheme`](../../middlewares/redirectscheme.md) named `my-redirect`, you'd write `traefik.http.middlewares.my-redirect.redirectscheme.scheme: https`.
+
+More information about available middlewares in the dedicated [middlewares section](../../middlewares/overview.md).
+
+!!! warning "The character `@` is not authorized in the middleware name."
+
+??? example "Declaring and Referencing a Middleware"
+    
+    ```yaml
+    # ...
+    # Declaring a middleware
+    traefik.http.middlewares.my-redirect.redirectscheme.scheme=https
+    # Referencing a middleware
+    traefik.http.routers.my-service.middlewares=my-redirect
+    ```
+
+!!! warning "Conflicts in Declaration"
+
+    If you declare multiple middleware with the same name but with different parameters, the middleware fails to be declared.
+
+### TCP
+
+You can declare TCP Routers and/or Services using labels.
+
+??? example "Declaring TCP Routers and Services"
+
+    ```yaml
+    traefik.tcp.routers.my-router.rule=HostSNI(`example.com`)
+    traefik.tcp.routers.my-router.tls=true
+    traefik.tcp.services.my-service.loadbalancer.server.port=4123
+    ```
+
+!!! warning "TCP and HTTP"
+
+    If you declare a TCP Router/Service, it will prevent Traefik from automatically creating an HTTP Router/Service (like it does by default if no TCP Router/Service is defined).
+    You can declare both a TCP Router/Service and an HTTP Router/Service for the same elastic service (but you have to do so manually).
+
+#### TCP Routers

+
+### Specific Provider Options
+
+#### `traefik.enable`
+
+```yaml
+traefik.enable=true
+```
+
+You can tell Traefik to consider (or not) the ECS service by setting `traefik.enable` to true or false.
+
+This option overrides the value of `exposedByDefault`.
