Executing shell commands on your container

To troubleshoot some isses, you might have to access the container to execute commands directly on the container itself. You can access a container through a bash shell or through PowerShell using the kubectl exec command.

  1. Use kubectl describe pods to find the name of the Pod in your cluster that you want to connect to.

    In the following example, the command lists the suitecrm-0 pod.

    kubectl describe pods | grep Name
    
    Name:               suitecrm-0
  2. Execute shell commands using one of the following methods:
    • Use kubectl exec to open a bash command shell where you can execute commands.
      kubectl exec -it pod-name -- /bin/bash

      The following example gets a shell to the suitecrm-0 pod:

      kubectl exec -it suitecrm-0 -- /bin/bash
    • Use kubectl exec to execute commands directly.
      kubectl exec -it pod-name -- /bin/bash -c "command(s)"

      The following example lists the root directory of the suitecrm-0 pod:

      kubectl exec -it suitecrm-0 -- /bin/bash -c "ls /"
