Checking the Edge Gateway and containers

Verify that the Edge Gateway containers are running correctly.

To verify that the Edge Gateway containers are running correctly, run the following command on the Edge Gateway system.

sudo kubectl get pods -A -l app.kubernetes.io/name=controller

Make sure that the 'NAME' column in the middle has an entry for deployment-operator-<unique_ID> and an entry for deployment-synchronizer-<unique_ID>. Make sure that the STATUS is Running.

If the containers are not running, use the kubectl describe command to determine the cause of the issue, especially the Events section.

sudo kubectl describe pod/<container_name> -n <namespace>

The Edge Gateway have runtime status probes available. When a problem occurs inside the containers, the cluster tries to resolve the problem by restarting the containers. You can check the container restart counter by listing the pods.

sudo kubectl get pods -n <namespace>

If the RESTARTS counter keeps increasing, use the following command to trigger a self-check on each Edge Gateway, and collect the logs by using kubectl.

sudo manageAppHost checkconnection [--controller-id <namespace>]

The tool also lists all of the detected Edge Gateway.
