Marathon Backend

Træfik can be configured to use Marathon as a backend configuration.

See also Marathon user guide.

Configuration

################################################################
# Mesos/Marathon configuration backend
################################################################

# Enable Marathon configuration backend.
[marathon]

# Marathon server endpoint.
# You can also specify multiple endpoint for Marathon:
# endpoint = "http://10.241.1.71:8080,10.241.1.72:8080,10.241.1.73:8080"
#
# Required
# Default: "http://127.0.0.1:8080"
#
endpoint = "http://127.0.0.1:8080"

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

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

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

# Expose Marathon apps by default in Traefik.
#
# Optional
# Default: true
#
# exposedByDefault = false

# Convert Marathon groups to subdomains.
# Default behavior: /foo/bar/myapp => foo-bar-myapp.{defaultDomain}
# with groupsAsSubDomains enabled: /foo/bar/myapp => myapp.bar.foo.{defaultDomain}
#
# Optional
# Default: false
#
# groupsAsSubDomains = true

# Enable compatibility with marathon-lb labels.
#
# Optional
# Default: false
#
# marathonLBCompatibility = true

# Enable filtering using Marathon constraints..
# If enabled, Traefik will read Marathon constraints, as defined in https://mesosphere.github.io/marathon/docs/constraints.html
# Each individual constraint will be treated as a verbatim compounded tag.
# i.e. "rack_id:CLUSTER:rack-1", with all constraint groups concatenated together using ":"
#
# Optional
# Default: false
#
# filterMarathonConstraints = true

# Enable Marathon basic authentication.
#
# Optional
#
#    [marathon.basic]
#    httpBasicAuthUser = "foo"
#    httpBasicPassword = "bar"

# TLS client configuration. https://golang.org/pkg/crypto/tls/#Config
#
# Optional
#
#    [marathon.TLS]
#    CA = "/etc/ssl/ca.crt"
#    Cert = "/etc/ssl/marathon.cert"
#    Key = "/etc/ssl/marathon.key"
#    insecureSkipVerify = true

# DCOSToken for DCOS environment.
# This will override the Authorization header.
#
# Optional
#
# dcosToken = "xxxxxx"

# Override DialerTimeout.
# Amount of time to allow the Marathon provider to wait to open a TCP connection
# to a Marathon master.
# 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.
#
# Optional
# Default: "60s"
#
# dialerTimeout = "60s"

# Set the TCP Keep Alive interval for the Marathon HTTP Client.
# 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.
#
# Optional
# Default: "10s"
#
# keepAlive = "10s"

# By default, a task's IP address (as returned by the Marathon API) is used as
# backend server if an IP-per-task configuration can be found; otherwise, the
# name of the host running the task is used.
# The latter behavior can be enforced by enabling this switch.
#
# Optional
# Default: false
#
# forceTaskHostname = true

# Applications may define readiness checks which are probed by Marathon during
# deployments periodically and the results exposed via the API.
# Enabling the following parameter causes Traefik to filter out tasks
# whose readiness checks have not succeeded.
# Note that the checks are only valid at deployment times.
# See the Marathon guide for details.
#
# Optional
# Default: false
#
# respectReadinessChecks = true

To enable constraints see backend-specific constraints section.

Labels: overriding default behavior

Marathon labels may be used to dynamically change the routing and forwarding behavior.

They may be specified on one of two levels: Application or service.

Application Level

The following labels can be defined on Marathon applications. They adjust the behavior for the entire application.

Label Description
traefik.enable=false Disable this container in Træfik
traefik.port=80 Register this port. Useful when the container exposes multiples ports.
traefik.portIndex=1 Register port by index in the application's ports array. Useful when the application exposes multiple ports.
