# Rancher Provider

Træfik can be configured to use Rancher as a provider.

## Global Configuration

```toml
################################################################
# Rancher Provider
################################################################

# Enable Rancher Provider.
[rancher]

# Default domain used.
# Can be overridden by setting the "traefik.domain" label on an service.
#
# Required
#
domain = "rancher.localhost"

# Enable watch Rancher changes.
#
# Optional
# Default: true
#
watch = true

# Polling interval (in seconds).
#
# Optional
# Default: 15
#
refreshSeconds = 15

# Expose Rancher services by default in Traefik.
#
# Optional
# Default: true
#
exposedByDefault = false

# Filter services with unhealthy states and inactive states.
#
# Optional
# Default: false
#
enableServiceHealthFilter = true

# Override default configuration template.
# For advanced users :)
#
# Optional
#
# filename = "rancher.tmpl"

# Override template version
# For advanced users :)
#
# Optional
# - "1": previous template version (must be used only with older custom templates, see "filename")
# - "2": current template version (must be used to force template version when "filename" is used)
#
# templateVersion = 2
```

To enable constraints see [provider-specific constraints section](/configuration/commons/#provider-specific).

## Rancher Metadata Service

```toml
# Enable Rancher metadata service provider instead of the API
# provider.
#
# Optional
# Default: false
#
[rancher.metadata]

# Poll the Rancher metadata service for changes every `rancher.refreshSeconds`.
# NOTE: this is less accurate than the default long polling technique which
# will provide near instantaneous updates to Traefik
#
# Optional
# Default: false
#
intervalPoll = true

# Prefix used for accessing the Rancher metadata service.
#
# Optional
# Default: "/latest"
#
prefix = "/2016-07-29"
```

## Rancher API

```toml
# Enable Rancher API provider.
#
# Optional
# Default: true
#
[rancher.api]

# Endpoint to use when connecting to the Rancher API.
#
# Required
endpoint = "http://rancherserver.example.com/v1"

# AccessKey to use when connecting to the Rancher API.
#
# Required
accessKey = "XXXXXXXXXXXXXXXXXXXX"

# SecretKey to use when connecting to the Rancher API.
#
# Required
secretKey = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
```

!!! note
    If Traefik needs access to the Rancher API, you need to set the `endpoint`, `accesskey` and `secretkey` parameters.

    To enable Traefik to fetch information about the Environment it's deployed in only, you need to create an `Environment API Key`.
    This can be found within the API Key advanced options.

    Add these labels to traefik docker deployment to autogenerated these values:
    ```
    io.rancher.container.agent.role: environment
    io.rancher.container.create_agent: true
    ```

## Labels: overriding default behavior

### On Containers

Labels can be used on task containers to override default behavior:

### On containers with Multiple Ports (segment labels)

Segment labels are used to define routes to a container exposing multiple ports.
A segment is a group of labels that apply to a port exposed by a container.
You can define as many segments as ports exposed in a container.

Segment labels override the default behavior.
