@Daxcor69 Thanks for reporting this issue. Could you please let us know what is the version Kubernetes Python Client? like -

# pip list |grep kubernetes
kubernetes                    23.3.0

[Daxcor69]

brad@development1:~$ pip list |grep kubernetes
kubernetes             25.3.0

Kubernetes version:

Client Version: v1.26.0 Kustomize Version: v4.5.7 Server Version: v1.26.0

[Daxcor69]

I know it is the holidays.. any thoughts on how I can proceed?

[gravesm]

@Daxcor69 I can't reproduce this. I just confirmed that the k8s_drain module works with collection version 2.3.2 and the python kubernetes library version 25.3.0. The error you are getting suggests that the python kubernetes library is not installed for the interpreter that's executing the module.

[gravesm]

You can try specifying the path to the python interpreter that has the kubernetes library installed just to verify that it's working. Use something like:

- name: Cordoning worker node to reboot.
    kubernetes.core.k8s_drain:
    state: cordon
    name: "{{ ansible_hostname }}"
  delegate_to: 127.0.0.1
  vars:
    ansible_python_interpreter: /path/to/python
