# Traefik & ECS
|
|
|
|
A Story of Labels & Elastic Containers
|
|
{: .subtitle }
|
|
|
|
Attach labels to your containers and let Traefik do the rest!
|
|
|
|
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 Configuration
|
|
|
|
!!! info "labels"
|
|
|
|
- labels are case-insensitive.
|
|
- The complete list of labels can be found in [the reference page](../../reference/routing-configuration/other-providers/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>`."

### Services

|
|
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/http/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).
|
|
|

### UDP
|
|
|
|
You can declare UDP Routers and/or Services using tags.
|
|
|
|
??? 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

See [entry points](../routers/index.md#entrypoints_2) for more information.
|
|
|
|
```yaml
|
|
traefik.udp.routers.myudprouter.entrypoints=ep1,ep2
|
|
```
|
|
|
|
??? info "`traefik.udp.routers.<router_name>.service`"
|
|
|
|
See [service](../routers/index.md#services_1) for more information.
|
|
|
|
```yaml
|
|
traefik.udp.routers.myudprouter.service=myservice
|
|
```
|
|
|
|
#### UDP Services
|
|
|
|
??? info "`traefik.udp.services.<service_name>.loadbalancer.server.port`"
|
|
|
|
Registers a port of the application.
|
|
|
|
```yaml
|
|
traefik.udp.services.myudpservice.loadbalancer.server.port=423
|
|
```
|
|
|
|
### 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`.
