Kubectl command to figure out Linux distro and version

Question

Is there a Kubectl command to figure out the following info about a Pod?

1. The installed Linux distribution

2. The OS version

Let's say you don't really have a good deal of info about the image with which a Deployment or a Pod has been created...

Answer 1

Something as simple as this using exec will result the os details

$ kubectl exec -it nginx1 -- /bin/bash -c "cat /etc/os-release;uname -r"

Should result this
