Configure Kiali for multicluster

We will configure Kiali to access the remote cluster. This will require a secret (similar to the Istio secret) containing the credentials for Kiali to fetch information from the remote cluster:

curl -L -o kiali-prepare-remote-cluster.sh https://raw.githubusercontent.com/kiali/kiali/master/hack/istio/multicluster/kiali-prepare-remote-cluster.sh

chmod +x kiali-prepare-remote-cluster.sh

./kiali-prepare-remote-cluster.sh --kiali-cluster-context $CLUSTER_EAST --remote-cluster-context $CLUSTER_WEST

Finally, upgrade the installation for Kiali to pick up the secret:

kubectl config use-context $CLUSTER_EAST

helm upgrade --install --namespace istio-system --set auth.strategy=anonymous --set deployment.logger.log_level=debug --set deployment.ingress.enabled=true --repo https://kiali.org/helm-charts kiali-server kiali-server

As result, we can quickly see that a new namespace appear in the Overview, the istio-system namespace from west cluster:
