Traefik & Marathon
Traefik can be configured to use Marathon as a provider. {: .subtitle }
See also Marathon user guide.
Routing Configuration
!!! info "Labels"
- Labels are case insensitive.
- The complete list of labels can be found in [the reference page](../../reference/dynamic-configuration/marathon.md).
General
Traefik creates, for each Marathon application, a corresponding service and router.
The Service automatically gets a server per instance of the application, and the router automatically gets a rule defined by defaultRule (if no rule for it was defined in labels).
Service definition
--8<-- "content/routing/providers/service-by-label.md"
??? example "Automatic service assignment with labels"
Service myservice gets automatically assigned to router myproxy.
```json
labels: {
"traefik.http.routers.myproxy.rule": "Host(`foo.com`)",
"traefik.http.services.myservice.loadbalancer.server.port": "80"
}
```
??? example "Automatic service creation and assignment with labels"
No service specified or defined, and yet one gets automatically created.
and assigned to router myproxy.
```json
labels: {
"traefik.http.routers.myproxy.rule": "Host(`foo.com`)"
}
```
Routers
To update the configuration of the Router automatically attached to the application,
add labels starting with traefik.http.routers.{router-name-of-your-choice}. and followed by the option you want to change.
For example, to change the routing rule, you could add the label "traefik.http.routers.routername.rule": "Host(`mydomain.com`)".

To update the configuration of the Service automatically attached to the container,
add labels starting with traefik.http.services.{service-name-of-your-choice}., followed by the option you want to change.

Middleware
You can declare pieces of middleware using labels starting with traefik.http.middlewares.{middleware-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"
```json
{
...
"labels": {
"traefik.http.middlewares.my-redirect.redirectscheme.scheme": "https",
"traefik.http.routers.my-container.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"
```json
{
...
"labels": {
"traefik.tcp.routers.my-router.rule": "HostSNI(`my-host.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 container (but you have to do so manually).

traefik.enable
"traefik.enable": "true"
Setting this option controls whether Traefik exposes the application.
It overrides the value of exposedByDefault.
traefik.marathon.ipadressidx
"traefik.marathon.ipadressidx": "1"
If a task has several IP addresses, this option specifies which one, in the list of available addresses, to select.
