EastWest Routing

EastWest routing allows you to easily configure high-availability for internal services across multiple clusters. Currently (TSB 1.6) this feature is disabled by default and will be enabled by default in a future release.

Enable Tier2 Gateway to act as EastWest Gateway in App Cluster​

To enable EastWest routing and failover, you will need to edit xcp component in ControlPlane CR or Helm values and add an environment variable ENABLE_ENHANCED_EAST_WEST_ROUTING with value true:

spec:
  components:
    xcp:
      ...
      kubeSpec:
        overlays:
          - apiVersion: install.xcp.tetrate.io/v1alpha1
            kind: EdgeXcp
            name: edge-xcp
            patches:
              ...
              - path: spec.components.edgeServer.kubeSpec.deployment.env[-1]
                value:
                  name: ENABLE_ENHANCED_EAST_WEST_ROUTING
                  value: "true"
  ...
