Test metallb-system namespace doesn't actually test to see if the namespace exists

[travellingtechie]

While researching another issue, I realized the output of this command was just a long usage page, so in testing further I discovered that Test metallb-system namespace in k3s_server_post/tasks/metallb.yml always succeeds, even if the namespace doesn't exit

Expected Behavior

the command 'k3s kubectl -n metallb-system' should return a 1 if the namespace metallb-system doesn't exist

Current Behavior

it always returns 0, and just returns a usage page, doesn't actually test to see if the namespace exists

Steps to Reproduce

run k3s kubectl -n metallb-system from the command line, it doesn't check if the namespace exists, just returns usage.

Context (variables)

Operating system: Ubuntu 22.04

Hardware:

Variables Used

all.yml

NA

Possible Solution

I changed the task to:

- name: Test metallb-system namespace
  shell: >-
    k3s kubectl get namespaces | grep metallb-system
  changed_when: false
  with_items: "{{ groups[group_name_master | default('master')] }}"
  run_once: true

I had to change to shell from command to get the pip to work. There may be a more elegant solution.
