Traefik creates, for each container, a corresponding [service](../routing/services/index.md) and [router](../routing/routers/index.md).
The Service automatically gets a server per instance of the container,
and the router automatically gets a rule defined by defaultRule (if no rule for it was defined in labels).
### Routers
To update the configuration of the Router automatically attached to the container, add labels starting with `traefik.http.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-container.rule=Host(my-domain)`.
Every [Router](../routing/routers/index.md) parameter can be updated this way.
### Services
To update the configuration of the Service automatically attached to the container, 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`.
Every [Service](../routing/services/index.md) parameter can be updated this way.
### 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`.
??? example "Declaring and Referencing a Middleware"
```yaml
services:
my-container:
# ...
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.
More information about available middlewares in the dedicated [middlewares section](../middlewares/overview.md).
### TCP
You can declare TCP Routers and/or Services using labels.
??? example "Declaring TCP Routers and Services"
```yaml
services:
my-container:
# ...
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).
### Specific Options
#### `traefik.enable`
You can tell Traefik to consider (or not) the container by setting `traefik.enable` to true or false.
This option overrides the value of `exposedByDefault`.
#### `traefik.docker.network`
Overrides the default docker network to use for connections to the container.
If a container is linked to several networks, be sure to set the proper network name (you can check this with `docker inspect <container_id>`), otherwise it will randomly pick one (depending on how docker is returning them).
!!! warning
When deploying a stack from a compose file `stack`, the networks defined are prefixed with `stack`.
#### `traefik.docker.lbswarm`
Enables Swarm's inbuilt load balancer (only relevant in Swarm Mode).
If you enable this option, Traefik will use the virtual IP provided by docker swarm instead of the containers IPs.
Which means that Traefik will not perform any kind of load balancing and will delegate this task to swarm.

@ -8,6 +8,10 @@ Traefik used to support Kubernetes only through the [Kubernetes Ingress provider
However, as the community expressed the need to benefit from Traefik features without resorting to (lots of) annotations,
we ended up writing a [Custom Resource Definition](https://kubernetes.io/docs/concepts/extend-kubernetes/api-extension/custom-resources/) (alias CRD in the following) for an IngressRoute type, defined below, in order to provide a better way to configure access to a Kubernetes cluster.
## Resource Configuration

### Traefik IngressRoute definition
```yaml
--8<-- "content/providers/crd_ingress_route.yml"
```
That `IngressRoute` kind can then be used to define an `IngressRoute` object, such as in:
```yaml
apiVersion: traefik.containo.us/v1alpha1
kind: IngressRoute
metadata:
name: ingressroutefoo
spec:
entryPoints:
- web
routes:
# Match is the rule corresponding to an underlying router.
# Later on, match could be the simple form of a path prefix, e.g. just "/bar",
# but for now we only support a traefik style matching rule.
- match: Host(`foo.com`) && PathPrefix(`/bar`)
# kind could eventually be one of "Rule", "Path", "Host", "Method", "Header",
# "Parameter", etc, to support simpler forms of rule matching, but for now we
# only support "Rule".
kind: Rule
# (optional) Priority disambiguates rules of the same length, for route matching.
priority: 12
services:
- name: whoami
port: 80
# (default 1) A weight used by the weighted round-robin strategy (WRR).
weight: 1
# (default true) PassHostHeader controls whether to leave the request's Host
# Header as it was before it reached the proxy, or whether to let the proxy set it
# to the destination (backend) host.
passHostHeader: true
responseForwarding:
# (default 100ms) Interval between flushes of the buffered response body to the client.
flushInterval: 100ms
---
apiVersion: traefik.containo.us/v1alpha1
kind: IngressRouteTCP
metadata:
name: ingressroutetcpfoo.crd
spec:
entryPoints:
- footcp
routes:
# Match is the rule corresponding to an underlying router.
- match: HostSNI(`*`)
services:
- name: whoamitcp
port: 8080
```
### Middleware
Additionally, to allow for the use of middlewares in an `IngressRoute`, we defined the CRD below for the `Middleware` kind.
```yaml
--8<-- "content/providers/crd_middlewares.yml"
```
Once the `Middleware` kind has been registered with the Kubernetes cluster, it can then be used in `IngressRoute` definitions, such as:
```yaml
apiVersion: traefik.containo.us/v1alpha1
kind: Middleware
metadata:
name: stripprefix
namespace: foo
spec:
stripPrefix:
prefixes:
- /stripit
---
apiVersion: traefik.containo.us/v1alpha1
kind: IngressRoute
metadata:
name: ingressroutebar
spec:
entryPoints:
- web
routes:
- match: Host(`bar.com`) && PathPrefix(`/stripit`)
kind: Rule
services:
- name: whoami
port: 80
middlewares:
- name: stripprefix
namespace: foo
```
!!! important "Cross-provider namespace"
As Kubernetes also has its own notion of namespace, one should not confuse the kubernetes namespace of a resource
(in the reference to the middleware) with the [provider namespace](../middlewares/overview.md#provider-namespace),
when the definition of the middleware is from another provider.
In this context, specifying a namespace when referring to the resource does not make any sense, and will be ignored.
More information about available middlewares in the dedicated [middlewares section](../middlewares/overview.md).
### TLS Option
Additionally, to allow for the use of TLS options in an IngressRoute, we defined the CRD below for the TLSOption kind.
More information about TLS Options is available in the dedicated [TLS Configuration Options](../../https/tls/#tls-options).
```yaml
--8<-- "content/providers/crd_tls_option.yml"
```
Once the TLSOption kind has been registered with the Kubernetes cluster or defined in the File Provider, it can then be used in IngressRoute definitions, such as:
```yaml
apiVersion: traefik.containo.us/v1alpha1
kind: TLSOption
metadata:
name: mytlsoption
namespace: default
spec:
minVersion: VersionTLS12
---
apiVersion: traefik.containo.us/v1alpha1
kind: IngressRoute
metadata:
name: ingressroutebar
spec:
entryPoints:
- web
routes:
- match: Host(`bar.com`) && PathPrefix(`/stripit`)
kind: Rule
services:
- name: whoami
port: 80
tls:
options:
name: mytlsoption
namespace: default
```
!!! important "References and namespaces"
If the optional `namespace` attribute is not set, the configuration will be applied with the namespace of the IngressRoute.
Additionally, when the definition of the TLS option is from another provider,
the cross-provider syntax (`middlewarename@provider`) should be used to refer to the TLS option,
just as in the [middleware case](../middlewares/overview.md#provider-namespace).
Specifying a namespace attribute in this case would not make any sense, and will be ignored.
### TLS
To allow for TLS, we made use of the `Secret` kind, as it was already defined, and it can be directly used in an `IngressRoute`:
```yaml
apiVersion: v1
kind: Secret
metadata:
name: supersecret
data:
tls.crt: LS0tLS1CRUdJTiBDRVJUSUZJQ0FURS0tLS0tCi0tLS0tRU5EIENFUlRJRklDQVRFLS0tLS0=
tls.key: LS0tLS1CRUdJTiBQUklWQVRFIEtFWS0tLS0tCi0tLS0tRU5EIFBSSVZBVEUgS0VZLS0tLS0=
---
apiVersion: traefik.containo.us/v1alpha1
kind: IngressRoute
metadata:
name: ingressroutetls
spec:
entryPoints:
- web
routes:
- match: Host(`foo.com`) && PathPrefix(`/bar`)
kind: Rule
services:
- name: whoami
port: 443
tls:
secretName: supersecret
```

Traefik creates, for each Marathon application, a corresponding [service](../routing/services/index.md) and [router](../routing/routers/index.md).
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).

}
}
```
!!! warning "TCP and HTTP"
If you declare a TCP Router/Service, it will prevent Traefik from automatically creating an HTTP Router/Service (as it would by default if no TCP Router/Service is defined).
Both a TCP Router/Service and an HTTP Router/Service can be created for the same application, but it has to be done explicitly in the config.
### Specific Options
#### `traefik.enable`
Setting this option controls whether Traefik exposes the application.

### Transport
#### `respondingTimeouts`
`respondingTimeouts` are timeouts for incoming requests to the Traefik instance.
??? info "`transport.respondingTimeouts.readTimeout`"
_Optional, Default=0s_
`readTimeout` is the maximum duration for reading the entire request, including the body.
If zero, no timeout exists.
Can be provided in a format supported by [time.ParseDuration](https://golang.org/pkg/time/#ParseDuration) or as raw values (digits).
If no units are provided, the value is parsed assuming seconds.

??? info "`transport.respondingTimeouts.writeTimeout`"
_Optional, Default=0s_
`writeTimeout` is the maximum duration before timing out writes of the response.
It covers the time from the end of the request header read to the end of the response write.
If zero, no timeout exists.
Can be provided in a format supported by [time.ParseDuration](https://golang.org/pkg/time/#ParseDuration) or as raw values (digits).

#### `lifeCycle`
Controls the behavior of Traefik during the shutdown phase.
??? info "`lifeCycle.requestAcceptGraceTimeout`"
_Optional, Default=0s_
Duration to keep accepting requests prior to initiating the graceful termination period (as defined by the `graceTimeOut` option).
This option is meant to give downstream load-balancers sufficient time to take Traefik out of rotation.
Can be provided in a format supported by [time.ParseDuration](https://golang.org/pkg/time/#ParseDuration) or as raw values (digits).
If no units are provided, the value is parsed assuming seconds.
The zero duration disables the request accepting grace period, i.e., Traefik will immediately proceed to the grace period.

### ProxyProtocol
Traefik supports [ProxyProtocol](https://www.haproxy.org/download/2.0/doc/proxy-protocol.txt) version 1 and 2.
If proxyprotocol header parsing is enabled for the entry point, this entry point can accept connections with or without proxyprotocol headers.
If Proxy Protocol header parsing is enabled for the entry point, this entry point can accept connections with or without Proxy Protocol headers.
If the proxyprotocol header is passed, then the version is determined automatically.

# Traefik & Docker
A Story of Labels & Containers
{: .subtitle }
![Docker](../../assets/img/providers/docker.png)
Attach labels to your containers and let Traefik do the rest!
## Configuration Examples
??? example "Configuring Docker & Deploying / Exposing Services"
Enabling the docker provider
```toml tab="File (TOML)"
[providers.docker]
```
```yaml tab="File (YAML)"
providers:
docker: {}
```
```bash tab="CLI"
--providers.docker=true
```
Attaching labels to containers (in your docker compose file)
```yaml
version: "3"
services:
my-container:
# ...
labels:
- traefik.http.routers.my-container.rule=Host(`mydomain.com`)
```
??? example "Configuring Docker Swarm & Deploying / Exposing Services"
Enabling the docker provider (Swarm Mode)
```toml tab="File (TOML)"
[providers.docker]
# swarm classic (1.12-)
# endpoint = "tcp://127.0.0.1:2375"
# docker swarm mode (1.12+)
endpoint = "tcp://127.0.0.1:2377"
swarmMode = true
```
```yaml tab="File (YAML)"
providers:
docker:
# swarm classic (1.12-)
# endpoint = "tcp://127.0.0.1:2375"
# docker swarm mode (1.12+)
endpoint: "tcp://127.0.0.1:2375"
swarmMode: true
```
```bash tab="CLI"
--providers.docker.endpoint="tcp://127.0.0.1:2375"
--providers.docker.swarmMode=true
```
Attach labels to services (not to containers) while in Swarm mode (in your docker compose file)
```yaml
version: "3"
services:
my-container:
deploy:
labels:
- traefik.http.routers.my-container.rule=Host(`mydomain.com`)
- traefik.http.services.my-container-service.loadbalancer.server.port=8080
```
!!! important "Labels in Docker Swarm Mode"
While in Swarm Mode, Traefik uses labels found on services, not on individual containers.
Therefore, if you use a compose file with Swarm Mode, labels should be defined in the `deploy` part of your service.
This behavior is only enabled for docker-compose version 3+ ([Compose file reference](https://docs.docker.com/compose/compose-file/#labels-1)).
## Routing Configuration
!!! info "Labels"
- Labels are case insensitive.
- The complete list of labels can be found [the reference page](../../reference/dynamic-configuration/docker.md)
### General
Traefik creates, for each container, a corresponding [service](../services/index.md) and [router](../routers/index.md).
The Service automatically gets a server per instance of the container,
and the router automatically gets a rule defined by `defaultRule` (if no rule for it was defined in labels).
### Routers
To update the configuration of the Router automatically attached to the container,
add labels starting with `traefik.http.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-container.rule=Host(`mydomain.com`)```.
??? info "`traefik.http.routers.<router_name>.rule`"
See [rule](../routers/index.md#rule) for more information.
```yaml
- "traefik.http.routers.myrouter.rule=Host(`mydomain.com`)"
```
??? info "`traefik.http.routers.<router_name>.entrypoints`"
See [entry points](../routers/index.md#entrypoints) for more information.
```yaml

```
??? info "`traefik.http.routers.<router_name>.service`"
See [rule](../routers/index.md#service) for more information.
```yaml

```
### Services
To update the configuration of the Service automatically attached to the container,
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`.
??? info "`traefik.http.services.<service_name>.loadbalancer.server.port`"
Registers a port.
Useful when the container exposes multiples ports.
Mandatory for Docker Swarm.
```yaml

See [health check](../services/index.md#health-check) for more information.
```yaml
- "traefik.http.services.myservice.loadbalancer.healthcheck.timeout=10"
```
??? info "`traefik.http.services.<service_name>.loadbalancer.sticky`"
See [sticky sessions](../services/index.md#sticky-sessions) for more information.
```yaml
- "traefik.http.services.myservice.loadbalancer.sticky=true"
```
??? info "`traefik.http.services.<service_name>.loadbalancer.sticky.cookie.httponly`"

FlushInterval specifies the flush interval to flush to the client while copying the response body.
```yaml
- "traefik.http.services.myservice.loadbalancer.responseforwarding.flushinterval=10"
```
### 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).
??? example "Declaring and Referencing a Middleware"
```yaml
services:
my-container:
# ...
labels:
# Declaring a middleware
- traefik.http.middlewares.my-redirect.redirectscheme.scheme=https
# Referencing a middleware
- 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"
```yaml
services:
my-container:
# ...
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).
#### TCP Routers
??? info "`traefik.tcp.routers.<router_name>.entrypoints`"
See [entry points](../routers/index.md#entrypoints_1) for more information.
```yaml
- "traefik.tcp.routers.mytcprouter.entrypoints=ep1,ep2"
```
??? info "`traefik.tcp.routers.<router_name>.rule`"
See [rule](../routers/index.md#rule_1) for more information.
```yaml
- "traefik.tcp.routers.mytcprouter.rule=HostSNI(`myhost.com`)"
```
??? info "`traefik.tcp.routers.<router_name>.service`"
See [service](../routers/index.md#services) for more information.
```yaml
- "traefik.tcp.routers.mytcprouter.service=myservice"
```
??? info "`traefik.tcp.routers.<router_name>.tls`"
See [TLS](../routers/index.md#tls_1) for more information.
```yaml
- "traefik.tcp.routers.mytcprouter.tls=true"
```
??? info "`traefik.tcp.routers.<router_name>.tls.certresolver`"
See [certResolver](../routers/index.md#certresolver_1) for more information.
```yaml
- "traefik.tcp.routers.mytcprouter.tls.certresolver=myresolver"
```
??? info "`traefik.tcp.routers.<router_name>.tls.domains[n].main`"
See [domains](../routers/index.md#domains_1) for more information.
```yaml
- "traefik.tcp.routers.mytcprouter.tls.domains[0].main=foobar.com"
```
??? info "`traefik.tcp.routers.<router_name>.tls.domains[n].sans`"
See [domains](../routers/index.md#domains_1) for more information.
```yaml
- "traefik.tcp.routers.mytcprouter.tls.domains[0].sans=test.foobar.com,dev.foobar.com"
```
??? info "`traefik.tcp.routers.<router_name>.tls.options`"
See [options](../routers/index.md#options_1) for more information.
```yaml
- "traefik.tcp.routers.mytcprouter.tls.options=mysoptions"
```
??? info "`traefik.tcp.routers.<router_name>.tls.passthrough`"
See [TLS](../routers/index.md#tls_1) for more information.
```yaml
- "traefik.tcp.routers.mytcprouter.tls.passthrough=true"
```
#### TCP Services
??? info "`traefik.tcp.services.<service_name>.loadbalancer.server.port`"
Registers a port of the application.
```yaml
- "traefik.tcp.services.mytcpservice.loadbalancer.server.port=423"
```
??? info "`traefik.tcp.services.<service_name>.loadbalancer.terminationdelay`"
<!-- TODO doc terminationdelay in TCP services page -->
```yaml
- "traefik.tcp.services.mytcpservice.loadbalancer.terminationdelay=100"
```
### Specific Provider Options
#### `traefik.enable`
```yaml
- "traefik.enable=true"
```
You can tell Traefik to consider (or not) the container by setting `traefik.enable` to true or false.
This option overrides the value of `exposedByDefault`.
#### `traefik.docker.network`
```yaml
- "traefik.docker.network=mynetwork"
```
Overrides the default docker network to use for connections to the container.
If a container is linked to several networks, be sure to set the proper network name (you can check this with `docker inspect <container_id>`),
otherwise it will randomly pick one (depending on how docker is returning them).
!!! warning
When deploying a stack from a compose file `stack`, the networks defined are prefixed with `stack`.
#### `traefik.docker.lbswarm`
```yaml
- "traefik.docker.lbswarm=true"
```
Enables Swarm's inbuilt load balancer (only relevant in Swarm Mode).
If you enable this option, Traefik will use the virtual IP provided by docker swarm instead of the containers IPs.
Which means that Traefik will not perform any kind of load balancing and will delegate this task to swarm.

# but for now we only support a traefik style matching rule.
- match: Host(`foo.com`) && PathPrefix(`/bar`)
# kind could eventually be one of "Rule", "Path", "Host", "Method", "Header",
# "Parameter", etc, to support simpler forms of rule matching, but for now we
# only support "Rule".

### Middleware
Additionally, to allow for the use of middlewares in an `IngressRoute`, we defined the CRD below for the `Middleware` kind.
```yaml
--8<-- "content/routing/providers/crd_middlewares.yml"
```
Once the `Middleware` kind has been registered with the Kubernetes cluster, it can then be used in `IngressRoute` definitions, such as:
```yaml
apiVersion: traefik.containo.us/v1alpha1
kind: Middleware
metadata:
name: stripprefix
namespace: foo
spec:
stripPrefix:
prefixes:
- /stripit
---
apiVersion: traefik.containo.us/v1alpha1
kind: IngressRoute
metadata:
name: ingressroutebar
spec:
entryPoints:
- web
routes:
- match: Host(`bar.com`) && PathPrefix(`/stripit`)
kind: Rule
services:
- name: whoami
port: 80
middlewares:
- name: stripprefix
namespace: foo
```
!!! important "Cross-provider namespace"
As Kubernetes also has its own notion of namespace, one should not confuse the kubernetes namespace of a resource
(in the reference to the middleware) with the [provider namespace](../../middlewares/overview.md#provider-namespace),
when the definition of the middleware is from another provider.
In this context, specifying a namespace when referring to the resource does not make any sense, and will be ignored.
More information about available middlewares in the dedicated [middlewares section](../../middlewares/overview.md).
### TLS Option
Additionally, to allow for the use of TLS options in an IngressRoute, we defined the CRD below for the TLSOption kind.
More information about TLS Options is available in the dedicated [TLS Configuration Options](../../../https/tls/#tls-options).
```yaml
--8<-- "content/routing/providers/crd_tls_option.yml"
```
Once the TLSOption kind has been registered with the Kubernetes cluster or defined in the File Provider, it can then be used in IngressRoute definitions, such as:
```yaml
apiVersion: traefik.containo.us/v1alpha1
kind: TLSOption
metadata:
name: mytlsoption
namespace: default
spec:
minVersion: VersionTLS12
---
apiVersion: traefik.containo.us/v1alpha1
kind: IngressRoute
metadata:
name: ingressroutebar
spec:
entryPoints:
- web
routes:
- match: Host(`bar.com`) && PathPrefix(`/stripit`)
kind: Rule
services:
- name: whoami
port: 80
tls:
options:
name: mytlsoption
namespace: default
```
!!! important "References and namespaces"
If the optional `namespace` attribute is not set, the configuration will be applied with the namespace of the IngressRoute.
Additionally, when the definition of the TLS option is from another provider,
the cross-provider syntax (`middlewarename@provider`) should be used to refer to the TLS option,
just as in the [middleware case](../../middlewares/overview.md#provider-namespace).
Specifying a namespace attribute in this case would not make any sense, and will be ignored.
### TLS
To allow for TLS, we made use of the `Secret` kind, as it was already defined, and it can be directly used in an `IngressRoute`:
```yaml
apiVersion: v1
kind: Secret
metadata:
name: supersecret
data:
tls.crt: LS0tLS1CRUdJTiBDRVJUSUZJQ0FURS0tLS0tCi0tLS0tRU5EIENFUlRJRklDQVRFLS0tLS0=
tls.key: LS0tLS1CRUdJTiBQUklWQVRFIEtFWS0tLS0tCi0tLS0tRU5EIFBSSVZBVEUgS0VZLS0tLS0=
---
apiVersion: traefik.containo.us/v1alpha1
kind: IngressRoute
metadata:
name: ingressroutetls
spec:
entryPoints:
- web
routes:
- match: Host(`foo.com`) && PathPrefix(`/bar`)
kind: Rule
services:
- name: whoami
port: 443
tls:
secretName: supersecret
```

# Traefik & Marathon
Traefik can be configured to use Marathon as a provider.
{: .subtitle }
See also [Marathon user guide](../../user-guides/marathon.md).
## Routing Configuration
!!! info "Labels"
- Labels are case insensitive.
- The complete list of labels can be found [the reference page](../../reference/dynamic-configuration/marathon.md)
### General
Traefik creates, for each Marathon application, a corresponding [service](../services/index.md) and [router](../routers/index.md).
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).
### 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`)"```.
??? info "`traefik.http.routers.<router_name>.rule`"
See [rule](../routers/index.md#rule) for more information.
```json

### Services
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.
For example, to change the passHostHeader behavior, you'd add the label `"traefik.http.services.servicename.loadbalancer.passhostheader": "false"`.
??? info "`traefik.http.services.<service_name>.loadbalancer.server.port`"
Registers a port.
Useful when the container exposes multiples ports.

```
### 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`](../../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).
??? 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 (as it would by default if no TCP Router/Service is defined).
Both a TCP Router/Service and an HTTP Router/Service can be created for the same application, but it has to be done explicitly in the config.
### Specific Provider Options
#### `traefik.enable`
```json
"traefik.enable": "true"
```
Setting this option controls whether Traefik exposes the application.
It overrides the value of `exposedByDefault`.
#### `traefik.marathon.ipadressidx`
```json
"traefik.marathon.ipadressidx": "1"
```
If a task has several IP addresses, this option specifies which one, in the list of available addresses, to select.

# Traefik & Rancher
A Story of Labels, Services & Containers
{: .subtitle }
![Rancher](../../assets/img/providers/rancher.png)
Attach labels to your services and let Traefik do the rest!
!!! important "This provider is specific to Rancher 1.x."
Rancher 2.x requires Kubernetes and does not have a metadata endpoint of its own for Traefik to query.
As such, Rancher 2.x users should utilize the [Kubernetes provider](./kubernetes-crd.md) directly.
## Routing Configuration
!!! info "Labels"
- Labels are case insensitive.
- The complete list of labels can be found [the reference page](../../reference/dynamic-configuration/rancher.md)
### General
Traefik creates, for each rancher service, a corresponding [service](../services/index.md) and [router](../routers/index.md).
The Service automatically gets a server per container in this rancher service, 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 container, 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-container.rule=Host(`mydomain.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`](../../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).
??? example "Declaring and Referencing a Middleware"
```yaml
# ...
labels:
# Declaring a middleware
- traefik.http.middlewares.my-redirect.redirectscheme.scheme=https
# Referencing a middleware
- 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.
### Specific Provider Options
#### `traefik.enable`
```yaml
- "traefik.enable=true"
```
You can tell Traefik to consider (or not) the container by setting `traefik.enable` to true or false.
This option overrides the value of `exposedByDefault`.
#### Port Lookup
Traefik is capable of detecting the port to use, by following the default rancher flow.
That means, if you just expose lets say port `:1337` on the rancher ui, traefik will pick up this port and use it.

### TLS
#### General
When a TLS section is specified, it instructs Traefik that the current router is dedicated to TLS requests only (and that the router should ignore non-TLS requests).
By default, Traefik will terminate the SSL connections (meaning that it will send decrypted data to the services), but Traefik can be configured in order to let the requests pass through (keeping the data encrypted), and be forwarded to the service "as is".
