Service Fabric Backend

Træfik can be configured to use Service Fabric as a backend configuration.

See this repository for an example deployment package and further documentation.

Labels

The provider uses labels to configure how services are exposed through Træfik. These can be set using Extensions and the Property Manager API

Extensions

Set labels with extensions through the services ServiceManifest.xml file. Here is an example of an extension setting Træfik labels:

<StatelessServiceType ServiceTypeName="WebServiceType">
  <Extensions>
      <Extension Name="Traefik">
        <Labels xmlns="http://schemas.microsoft.com/2015/03/fabact-no-schema">
          <Label Key="traefik.frontend.rule.example2">PathPrefixStrip: /a/path/to/strip</Label>
          <Label Key="traefik.expose">true</Label>
          <Label Key="traefik.frontend.passHostHeader">true</Label>
        </Labels>
      </Extension>
  </Extensions>
</StatelessServiceType>

Property Manager

Set Labels with the property manager API to overwrite and add labels, while your service is running. Here is an example of adding a frontend rule using the property manager API.

curl -X PUT \
  'http://localhost:19080/Names/GettingStartedApplication2/WebService/$/GetProperty?api-version=6.0&IncludeValues=true' \
  -d '{
  "PropertyName": "traefik.frontend.rule.default",
  "Value": {
    "Kind": "String",
    "Data": "PathPrefixStrip: /a/path/to/strip"
  },
  "CustomTypeId": "LabelType"
}'

Note

This functionality will be released in a future version of the sfctl tool.

Available Labels

Labels, set through extensions or the property manager, can be used on services to override default behaviour.

Label Description
traefik.backend.maxconn.amount=10 Set a maximum number of connections to the backend.
Must be used in conjunction with the below label to take effect.
traefik.backend.maxconn.extractorfunc=client.ip Set the function to be used against the request to determine what to limit maximum connections to the backend by.
Must be used in conjunction with the above label to take effect.
traefik.backend.loadbalancer.method=drr Override the default wrr load balancer algorithm
traefik.backend.loadbalancer.stickiness=true Enable backend sticky sessions
traefik.backend.loadbalancer.stickiness.cookieName=NAME Manually set the cookie name for sticky sessions
traefik.backend.circuitbreaker.expression=EXPR Create a circuit breaker to be used against the backend
traefik.backend.weight=10 Assign this weight to the container
traefik.expose=true Expose this service using træfik
traefik.frontend.rule=EXPR Override the default frontend rule. Defaults to SF address.
traefik.frontend.passHostHeader=true Forward client Host header to the backend.
traefik.frontend.priority=10 Override default frontend priority
