# 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.
```yaml
traefik.http.routers.myrouter.rule=Host(`example.com`)
```

### Services
To update the configuration of the Service automatically attached to the service,
add labels starting with `traefik.http.services.{name-of-your-choice}.`, followed by the option you want to change.
For example, to change the `passHostHeader` behavior,
you'd add the label `traefik.http.services.{name-of-your-choice}.loadbalancer.passhostheader=false`.

### 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

??? example "Declaring UDP Routers and Services"
```yaml
traefik.udp.routers.my-router.entrypoints=udp
traefik.udp.services.my-service.loadbalancer.server.port=4123
```
!!! warning "UDP and HTTP"
If you declare a UDP Router/Service, it will prevent Traefik from automatically creating an HTTP Router/Service (like it does by default if no UDP Router/Service is defined).
You can declare both a UDP Router/Service and an HTTP Router/Service for the same elastic service (but you have to do so manually).
#### UDP Routers
??? info "`traefik.udp.routers.<router_name>.entrypoints`"

```
### 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`.
