TrafficRoute

• List of selectors to match data plane proxies that are sources of traffic.

  • match (optional)

    Tags to match, can be used for both source and destinations

• destinations (required, repeated)

  List of selectors to match services that are destinations of traffic.

  Notice the difference between sources and destinations. While the source of traffic is always a data plane proxy within a mesh, the destination is a service that could be either within or outside of a mesh.

  • match (optional)

    Tags to match, can be used for both source and destinations

• conf (required)

  Configuration for the route.

  • split (optional, repeated)

    List of destinations with weights assigned to them. When used, “destination” is not allowed.

    • weight (required)

      Weight assigned to that destination. Weights are not percentages. For example two destinations with weights the same weight “1” will receive both same amount of the traffic. 0 means that the destination will be ignored.

    • destination (required)

      Selector to match individual endpoints that comprise that destination.

      Notice that an endpoint can be either inside or outside the mesh. In the former case an endpoint corresponds to a data plane proxy, in the latter case an endpoint is an External Service.

  • loadBalancer (optional)

    Load balancer configuration for given “split” or “destination”

    • roundRobin (optional)

    • leastRequest (optional)

      • choiceCount (optional)

        The number of random healthy hosts from which the host with the fewest active requests will be chosen. Defaults to 2 so that we perform two-choice selection if the field is not set.

    • ringHash (optional)

      • hashFunction (optional)

        The hash function used to hash hosts onto the ketama ring. The value defaults to ‘XX_HASH’.

      • minRingSize (optional)

        Minimum hash ring size.

      • maxRingSize (optional)

        Maximum hash ring size.

    • random (optional)

    • maglev (optional)

  • destination (optional)

    One destination that the traffic will be redirected to. When used, “split” is not allowed.
