Nsm system restart (remote case)

This example shows that NSM keeps working after restarting all management resources.

NSC and NSE are using the memif mechanism to connect to its local forwarder. Forwarders are using the wireguard mechanism to connect with each other.

Requires

Make sure that you have completed steps from basic.

Run

Deploy NSC and NSE:

kubectl apply -k https://github.com/networkservicemesh/deployments-k8s/examples/heal/remote-nsm-system-restart-memif-ip?ref=e314a602db2c49c65e3e6de41e7f113c70bac3c3

Wait for applications ready:

kubectl wait --for=condition=ready --timeout=1m pod -l app=nsc-memif -n ns-remote-nsm-system-restart-memif-ip

kubectl wait --for=condition=ready --timeout=1m pod -l app=nse-memif -n ns-remote-nsm-system-restart-memif-ip

Ping from NSC to NSE:

result=$(kubectl exec deployments/nsc-memif -n ns-remote-nsm-system-restart-memif-ip -- vppctl ping 172.16.1.100 repeat 4)
echo ${result}
! echo ${result} | grep -E -q "(100% packet loss)|(0 sent)|(no egress interface)"

Ping from NSE to NSC:

result=$(kubectl exec deployments/nse-memif -n ns-remote-nsm-system-restart-memif-ip -- vppctl ping 172.16.1.101 repeat 4)
echo ${result}
! echo ${result} | grep -E -q "(100% packet loss)|(0 sent)|(no egress interface)"

Restart nsm-system:

kubectl delete mutatingwebhookconfiguration nsm-mutating-webhook
kubectl delete ns nsm-system

kubectl create ns nsm-system

kubectl apply -k https://github.com/networkservicemesh/deployments-k8s/examples/basic?ref=e314a602db2c49c65e3e6de41e7f113c70bac3c3

Ping from NSC to NSE:

result=$(kubectl exec deployments/nsc-memif -n ns-remote-nsm-system-restart-memif-ip -- vppctl ping 172.16.1.100 repeat 4)
echo ${result}
! echo ${result} | grep -E -q "(100% packet loss)|(0 sent)|(no egress interface)"

Ping from NSE to NSC:

result=$(kubectl exec deployments/nse-memif -n ns-remote-nsm-system-restart-memif-ip -- vppctl ping 172.16.1.101 repeat 4)
echo ${result}
! echo ${result} | grep -E -q "(100% packet loss)|(0 sent)|(no egress interface)"

Cleanup

Delete ns:

kubectl delete ns ns-remote-nsm-system-restart-memif-ip
