bash - Exec commands on kubernetes pods with root access

I have one pod running with name 'jenkins-app-2843651954-4zqdp'. I want to install few softwares temporarily on this pod. How can I do this?

I am trying this- kubectl exec -it jenkins-app-2843651954-4zqdp -- /bin/bash and then running apt-get install commands but since the user I am accessing with doesn't have sudo access I am not able to run commands

  • Use kubectl describe pod ... to find the node running your Pod and the container ID (docker://...)
  • SSH into the node
  • run docker exec -it -u root ID /bin/bash
