Marathon Provider

Traefik can be configured to use Marathon as a provider.

See also Marathon user guide.

Configuration

# Mesos/Marathon Provider
################################################################
# Enable Marathon Provider.
[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 base domain used for the frontend rules.
# 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: "5s"
#
# dialerTimeout = "5s"
# Override ResponseHeaderTimeout.
# Amount of time to allow the Marathon provider to wait until the first response
# header from the Marathon master is received.
# 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"
#
# responseHeaderTimeout = "60s"
# Override TLSHandshakeTimeout.
# Amount of time to allow the Marathon provider to wait until the TLS
# handshake completes.
# 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: "5s"
#
# TLSHandshakeTimeout = "5s"
# 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

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.

Applications with Multiple Ports (segment labels)

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

Segment labels override the default behavior.
