How do I su root in a kubernetes pod?

I have an AWX kubernetes pod. Once I connect to the pod, how do I elevate to root?

Linux * Ansible * awx * kubernetes

To connect to a POD terminal, you can use

kubectl exec --stdin --tty POD_NAME_HERE -- /bin/bash

Open in new window

Don't think you can elevate to root.

Why would you want to elevate to root... the whole purpose of docker/kubernetes is to shield the host from it's guests. Allowing root inside a container would defeat the whole purpose of containers...

Hey Noci. AWX for ansible installs on a Kubernetes pod. I need to modify /etc/krb5.conf on the awx pod to have my ansible code talk to Windows servers via kerberos. Because I am not root, I can't modify config files.

Yujin,

I am familar with that command. It drops me to "bash-4.4$" with no privileges'.

Thanks

You could update the pod's Deployment so that /etc/krb5.conf is a mounted file, then you can define its contents from the host machine, or from a configmap.

Just remember that modifying a file in a running pod like this won't survive a pod restart.
