Is there a Kubectl command to figure out the following info about a Pod?
The installed Linux distribution
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...
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
