Interdomain basic NSM setup

In this example, NSM-system is deployed on three clusters. The third cluster is used as a floating-registry

Requires

• Load balancer
• Interdomain DNS
• Interdomain spire
  • Spire on first cluster
  • Spire on second cluster
  • Spire on third cluster
  • Spiffe Federation

Run

Apply NSM resources for cluster1:

kubectl --kubeconfig=$KUBECONFIG1 apply -k https://github.com/networkservicemesh/deployments-k8s/examples/interdomain/three_cluster_configuration/basic/cluster1?ref=7a2735f6f8c8ed02d058c1a6a2f04846a3d88cad

Apply NSM resources for cluster2:

kubectl --kubeconfig=$KUBECONFIG2 apply -k https://github.com/networkservicemesh/deployments-k8s/examples/interdomain/three_cluster_configuration/basic/cluster2?ref=7a2735f6f8c8ed02d058c1a6a2f04846a3d88cad

Apply NSM resources for cluster3:

kubectl --kubeconfig=$KUBECONFIG3 apply -k https://github.com/networkservicemesh/deployments-k8s/examples/interdomain/three_cluster_configuration/basic/cluster3?ref=7a2735f6f8c8ed02d058c1a6a2f04846a3d88cad

Wait for nsmgr-proxy-service exposing:

kubectl --kubeconfig=$KUBECONFIG1 get services nsmgr-proxy -n nsm-system -o go-template='{{index (index (index (index .status "loadBalancer") "ingress") 0) "ip"}}'

kubectl --kubeconfig=$KUBECONFIG2 get services nsmgr-proxy -n nsm-system -o go-template='{{index (index (index (index .status "loadBalancer") "ingress") 0) "ip"}}'

Wait for admission-webhook-k8s:

WH=$(kubectl --kubeconfig=$KUBECONFIG1 get pods -l app=admission-webhook-k8s -n nsm-system --template '{{range .items}}{{.metadata.name}}{{"\n"}}{{end}}')
kubectl --kubeconfig=$KUBECONFIG1 wait --for=condition=ready --timeout=1m pod ${WH} -n nsm-system

WH=$(kubectl --kubeconfig=$KUBECONFIG2 get pods -l app=admission-webhook-k8s -n nsm-system --template '{{range .items}}{{.metadata.name}}{{"\n"}}{{end}}')
kubectl --kubeconfig=$KUBECONFIG2 wait --for=condition=ready --timeout=1m pod ${WH} -n nsm-system

Wait for registry exposing:

kubectl --kubeconfig=$KUBECONFIG3 get services registry -n nsm-system -o go-template='{{index (index (index (index .status "loadBalancer") "ingress") 0) "ip"}}'

Cleanup

To free resources follow the next command:

kubectl --kubeconfig=$KUBECONFIG1 delete mutatingwebhookconfiguration nsm-mutating-webhook
kubectl --kubeconfig=$KUBECONFIG1 delete ns nsm-system

kubectl --kubeconfig=$KUBECONFIG2 delete mutatingwebhookconfiguration nsm-mutating-webhook
kubectl --kubeconfig=$KUBECONFIG2 delete ns nsm-system

kubectl --kubeconfig=$KUBECONFIG3 delete ns nsm-system
