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"
...
