KubeEdge Pre-Check

Status Check

After the Cloud and Edge parts have started, you can use below command to check the edge node status.

On cloud host run,

kubectl get nodes

or

kubectl get nodes -l node-role.kubernetes.io/edge=

Please make sure the status of edge node you created is ready.

Deploy Application on cloud side

Try out a sample application deployment by following below steps.

kubectl apply -f $GOPATH/src/github.com/kubeedge/kubeedge/build/deployment.yaml
deployment.apps/nginx-deployment created

Note: Currently, for applications running on edge nodes, we don't support kubectl logs and kubectl exec commands(will support in future release), support pod to pod communication running on edge nodes in same subnet using edgemesh.

Then you can use below command to check if the application is normally running.

Check the pod is up and is running state

kubectl get pods
NAME                               READY   STATUS    RESTARTS   AGE
nginx-deployment-d86dfb797-scfzz   1/1     Running   0          44s

Check the deployment is up and is in running state

kubectl get deployments

NAME               READY   UP-TO-DATE   AVAILABLE   AGE
nginx-deployment   1/1     1            1           63s

Monitoring containers status

If the container runtime configured to manage containers is containerd , then the following commands can be used to inspect container status and list images.

sudo ctr --namespace k8s.io containers ls
sudo ctr --namespace k8s.io images ls
sudo crictl exec -ti <containerid> /bin/bash
