Access vRouter CLI
You can access the command-line interface (CLI) of the vRouter by accessing the shell of the running vRouter-agent container.
The commands below are provided as an example. The vRouter pod name must be replaced from your environment. The command outputs may differ based on your environment.
List the running pods on the K8s Cluster:
kubectl get pods -A NAMESPACE NAME READY STATUS RESTARTS AGE contrail-deploy contrail-k8s-deployer-7b5dd699b9-nd7xf 1/1 Running 0 41m contrail contrail-vrouter-masters-dfxgm 3/3 Running 0 41m jcnr kube-crpd-worker-ds-8tnf7 1/1 Running 0 41m jcnr syslog-ng-54749b7b77-v24hq 1/1 Running 0 41m kube-system calico-kube-controllers-57b9767bdb-5wbj6 1/1 Running 2 (92d ago) 129d kube-system calico-node-j4m5b 1/1 Running 2 (92d ago) 129d kube-system coredns-8474476ff8-fpw78 1/1 Running 2 (92d ago) 129d kube-system dns-autoscaler-7f76f4dd6-q5vdp 1/1 Running 2 (92d ago) 129d kube-system kube-apiserver-5a5s5-node2 1/1 Running 3 (92d ago) 129d kube-system kube-controller-manager-5a5s5-node2 1/1 Running 4 (92d ago) 129d kube-system kube-multus-ds-amd64-4zm5k 1/1 Running 2 (92d ago) 129d kube-system kube-proxy-l6xm8 1/1 Running 2 (92d ago) 129d kube-system kube-scheduler-5a5s5-node2 1/1 Running 4 (92d ago) 129d kube-system nodelocaldns-6kwg5 1/1 Running 2 (92d ago) 129d
Copy the name of the vRouter pod—contrail-vrouter-masters-dfxgm in this
example output . You will use the pod name to connect to the running container's shell.
Issue the kubectl exec command to access the running container's shell:
kubectl exec -n <namespace> -it <pod name> --container <container name> -- bash
where <namespace> identifies the namespace in which the pod is running, <pod name> specificies the name of the pod and the <container name> specifies the name of the container (to be specified if the pod has more than one container).
The vRouter pod has three containers. When the container name is not specified, the command will default to the vrouter-agent container shell. Here is an example:
[root@jcnr-01]# kubectl exec -n contrail -it contrail-vrouter-masters-dfxgm -- bash Defaulted container "contrail-vrouter-agent" out of: contrail-vrouter-agent, contrail-vrouter-agent-dpdk, contrail-vrouter-telemetry-exporter, contrail-init (init), contrail-vrouter-kernel-init-dpdk (init) [root@jcnr-01 /]#
At this point, you have connected to the vRouter's CLI.
