    If you need to get an OS version of running container you should read

    https://kubernetes.io/docs/tasks/debug/debug-application/get-shell-running-container/

    as it described above you can get access to your running pod by command:

    kubectl exec –stdin –tty <pod_name> — /bin/bash

    then just type "cat /etc/os-release" and you will see the OS info which your pod running on. In most cases containers run on unix systems and you will find current pod OS.

    You also can install python or anything else inside your pod. But I do not recommend to do it. Containers have minimum thing to make you app work. For checking it is ok, but after it just deploy new container.

    Using the node info on which pod is running via kubectl. In the below command, replace the <PODNAME> with your pod name.

    kubectl get node $(kubectl get pod <PODNAME>  -o jsonpath='{.spec.nodeName}') -o jsonpath='{.status.nodeInfo.osImage}'
