Azure Service Fabric Provider

Traefik can be configured to use Azure Service Fabric as a provider.

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

Labels

The provider uses labels to configure how services are exposed through Traefik. 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 Traefik 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.enable">true</Label>
          <Label Key="traefik.frontend.passHostHeader">true</Label>
        </Labels>
      </Extension>
  </Extensions>
</StatelessServiceType>

Note: The Label tag and its Key attribute are case sensitive. That is, if you use label instead of Label or key instead of Key, they will be silently ignored.

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 behavior.
