Traefik (pronounced _traffic_) is a modern HTTP reverse proxy and load balancer that makes deploying microservices easy.
Traefik integrates with your existing infrastructure components ([Docker](https://www.docker.com/), [Swarm mode](https://docs.docker.com/engine/swarm/), [Kubernetes](https://kubernetes.io), [Marathon](https://mesosphere.github.io/marathon/), [Consul](https://www.consul.io/), [Etcd](https://coreos.com/etcd/), [Rancher](https://rancher.com), [Amazon ECS](https://aws.amazon.com/ecs), ...) and configures itself automatically and dynamically.

## Rancher v1
In v3, the rancher v1 provider has been removed because Rancher v1 is [no longer actively maintaned](https://rancher.com/docs/os/v1.x/en/support/) and v2 is supported as a standard Kubernetes provider.
Rancher 2.x requires Kubernetes and does not have a metadata endpoint of its own for Traefik to query.

# 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 CRD provider](./kubernetes-crd.md) directly.
## Configuration Examples
??? example "Configuring Rancher & Deploying / Exposing Services"
Enabling the Rancher provider
```yaml tab="File (YAML)"
providers:
rancher: {}
```
```toml tab="File (TOML)"
[providers.rancher]
```
```bash tab="CLI"
--providers.rancher=true
```
Attaching labels to services
```yaml
labels:
- traefik.http.services.my-service.rule=Host(`example.com`)
```
## Routing Configuration
See the dedicated section in [routing](../routing/providers/rancher.md).
## Provider Configuration
??? tip "Browse the Reference"
For an overview of all the options that can be set with the Rancher provider, see the following snippets:
```yaml tab="File (YAML)"
--8<-- "content/providers/rancher.yml"
```
```toml tab="File (TOML)"
--8<-- "content/providers/rancher.toml"
```
```bash tab="CLI"
--8<-- "content/providers/rancher.txt"
```
### `exposedByDefault`
_Optional, Default=true_
Expose Rancher services by default in Traefik.
If set to `false`, services that do not have a `traefik.enable=true` label are ignored from the resulting routing configuration.
For additional information, refer to [Restrict the Scope of Service Discovery](./overview.md#restrict-the-scope-of-service-discovery).
```yaml tab="File (YAML)"
providers:
rancher:
exposedByDefault: false
# ...
```
```toml tab="File (TOML)"
[providers.rancher]
exposedByDefault = false
# ...
```
```bash tab="CLI"
--providers.rancher.exposedByDefault=false
# ...
```
### `defaultRule`
_Optional, Default=```Host(`{{ normalize .Name }}`)```_
The default host rule for all services.
The `defaultRule` option defines what routing rule to apply to a container if no rule is defined by a label.
It must be a valid [Go template](https://pkg.go.dev/text/template/), and can use
[sprig template functions](https://masterminds.github.io/sprig/).
The service name can be accessed with the `Name` identifier,
and the template has access to all the labels defined on this container.
This option can be overridden on a container basis with the `traefik.http.routers.Router1.rule` label.
```yaml tab="File (YAML)"
providers:
rancher:
defaultRule: "Host(`{{ .Name }}.{{ index .Labels \"customLabel\"}}`)"
# ...
```
```toml tab="File (TOML)"
[providers.rancher]
defaultRule = "Host(`{{ .Name }}.{{ index .Labels \"customLabel\"}}`)"
# ...
```
```bash tab="CLI"
--providers.rancher.defaultRule=Host(`{{ .Name }}.{{ index .Labels \"customLabel\"}}`)
# ...
```
### `enableServiceHealthFilter`
_Optional, Default=true_
Filter out services with unhealthy states and inactive states.
```yaml tab="File (YAML)"
providers:
rancher:
enableServiceHealthFilter: false
# ...
```
```toml tab="File (TOML)"
[providers.rancher]
enableServiceHealthFilter = false
# ...
```
```bash tab="CLI"
--providers.rancher.enableServiceHealthFilter=false
# ...
```
### `refreshSeconds`
_Optional, Default=15_
Defines the polling interval (in seconds).
```yaml tab="File (YAML)"
providers:
rancher:
refreshSeconds: 30
# ...
```
```toml tab="File (TOML)"
[providers.rancher]
refreshSeconds = 30
# ...
```
```bash tab="CLI"
--providers.rancher.refreshSeconds=30
# ...
```
### `intervalPoll`
_Optional, Default=false_
Poll the Rancher metadata service for changes every `rancher.refreshSeconds`,
which is less accurate than the default long polling technique which provides near instantaneous updates to Traefik.
```yaml tab="File (YAML)"
providers:
rancher:
intervalPoll: true
# ...
```
```toml tab="File (TOML)"
[providers.rancher]
intervalPoll = true
# ...
```
```bash tab="CLI"
--providers.rancher.intervalPoll=true
# ...
```
### `prefix`
_Optional, Default="/latest"_
Prefix used for accessing the Rancher metadata service.
```yaml tab="File (YAML)"
providers:
rancher:
prefix: "/test"
# ...
```
```toml tab="File (TOML)"
[providers.rancher]
prefix = "/test"
# ...
```
```bash tab="CLI"
--providers.rancher.prefix=/test
# ...
```
### `constraints`
_Optional, Default=""_
The `constraints` option can be set to an expression that Traefik matches against the container labels to determine whether
to create any route for that container. If none of the container tags match the expression, no route for that container is
created. If the expression is empty, all detected containers are included.
The expression syntax is based on the `Label("key", "value")`, and `LabelRegex("key", "value")` functions, as well as
the usual boolean logic, as shown in examples below.
??? example "Constraints Expression Examples"
```toml
# Includes only containers having a label with key `a.label.name` and value `foo`
constraints = "Label(`a.label.name`, `foo`)"
```
```toml
# Excludes containers having any label with key `a.label.name` and value `foo`
constraints = "!Label(`a.label.name`, `value`)"
```
```toml
# With logical AND.
constraints = "Label(`a.label.name`, `valueA`) && Label(`another.label.name`, `valueB`)"
```
```toml
# With logical OR.
constraints = "Label(`a.label.name`, `valueA`) || Label(`another.label.name`, `valueB`)"
```
```toml
# With logical AND and OR, with precedence set by parentheses.
constraints = "Label(`a.label.name`, `valueA`) && (Label(`another.label.name`, `valueB`) || Label(`yet.another.label.name`, `valueC`))"
```
```toml
# Includes only containers having a label with key `a.label.name` and a value matching the `a.+` regular expression.
constraints = "LabelRegex(`a.label.name`, `a.+`)"
```
For additional information, refer to [Restrict the Scope of Service Discovery](./overview.md#restrict-the-scope-of-service-discovery).
```yaml tab="File (YAML)"
providers:
rancher:
constraints: "Label(`a.label.name`,`foo`)"
# ...
```
```toml tab="File (TOML)"
[providers.rancher]
constraints = "Label(`a.label.name`,`foo`)"
# ...
```
```bash tab="CLI"
--providers.rancher.constraints=Label(`a.label.name`,`foo`)
# ...
```

# 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 in [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.
#### Service definition
--8<-- "content/routing/providers/service-by-label.md"
??? example "Automatic service assignment with labels"
With labels in a compose file
```yaml
labels:
- "traefik.http.routers.myproxy.rule=Host(`example.net`)"
# service myservice gets automatically assigned to router myproxy
- "traefik.http.services.myservice.loadbalancer.server.port=80"
```
??? example "Automatic service creation and assignment with labels"
With labels in a compose file
```yaml
labels:
# no service specified or defined and yet one gets automatically created
# and assigned to router myproxy.
- "traefik.http.routers.myproxy.rule=Host(`example.net`)"
```
### 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(`example.com`)```.
!!! warning "The character `@` is not authorized in the router name `<router_name>`."
??? info "`traefik.http.routers.<router_name>.rule`"

### 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`.
!!! warning "The character `@` is not authorized in the service name `<service_name>`."

### 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
# ...
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(`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 container (but you have to do so manually).

See [serverstransport](../services/index.md#serverstransport_2) for more information.
```yaml
- "traefik.tcp.services.<service_name>.loadbalancer.serverstransport=foobar@file"
```
### UDP
You can declare UDP Routers and/or Services using labels.

services:
my-container:
# ...

```
!!! 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 container (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 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.
