Update k8s_exec and k8s_cp to include container name

[fluzzykitten]

SUMMARY

We need to specify a container in environments that use sidecar injection, like in the case of istio service mesh. If the container is not specified, and a side car is injected so there are multiple containers running in the pod, this task will fail because a container was not specified in a pod with multiple containers.

ISSUE TYPE

• Bug, Docs Fix or other nominal change
  Bug preventing backups in environments that use Istio service mesh or other automatic side-car injection

ADDITIONAL INFORMATION

Container that we create is the same name as the pod, so we just need to tell the backup to use the container we created, to differentiate it from any sidecars containers that might've been injected

Good point, thanks for the PR @fluzzykitten !

I checked that the container name is indeed correct:

• https://github.com/ansible/awx-operator/blob/devel/roles/backup/templates/management-pod.yml.j2#L11

However, I expect you will also need to specify the container here as well right @fluzzykitten ?

• awx-operator/roles/backup/tasks/awx-cro.yml

  Line 33 in e98c913

  pod: "{{ ansible_operator_meta.name }}-db-management"

• awx-operator/roles/backup/tasks/postgres.yml

  Line 128 in e98c913

  pod: "{{ ansible_operator_meta.name }}-db-management"

Actually, pretty much all of these places:

• https://github.com/search?q=repo%3Aansible%2Fawx-operator+pod%3A+%22%7B%7B+ansible_operator_meta.name+%7D%7D-db-management%22&type=code

While looking at this PR, I noticed this typo:

• Fix innocuous but confusing typo in db management pod task #1859

@rooftopcellist Shoot! You're right, I only pushed one of the files. My bad. MR updated with the other instances of the k8s_exec and k8s_cp modules that didn't set a container, and would be affected by sidecar container injection.

@fluzzykitten thanks for the quick update! I just tested out a backup and restore and didn't run into any issues. Thanks for the contribution!
