title	description
Traefik ECS Documentation	AWS ECS is a provider for routing and load balancing in Traefik Proxy. Read the technical documentation to get started.

Traefik & ECS

One of the best feature of Traefik is to delegate the routing configuration to the application level. With ECS, Traefik can leverage labels attached to a container to generate routing rules.

!!! warning "Labels & sensitive data"

We recommend to *not* use labels to store sensitive data (certificates, credentials, etc).
Instead, we recommend to store sensitive data in a safer storage (secrets, file, etc).

Routing Configurationred

!!! info "labels"

Labels are case-insensitive.

!!! tip "TLS Default Generated Certificates"

To learn how to configure Traefik default generated certificate, refer to the [TLS Certificates](../http/tls/tls-certificates.md#acme-default-certificate) page.

General

Traefik creates, for each elastic service, a corresponding service and router.

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`).

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 named my-redirect, you'd write traefik.http.middlewares.my-redirect.redirectscheme.scheme: https.

More information about available middlewares in the dedicated middlewares section.

!!! 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"

```

!!! 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).
