<p>I need to be able to execute some shell scripts inside my container from Ansible playbook.  Ansible play is running in another container in my cluster. Cluster is in RedHat OpenShift 4.3.</p>

<p>I am using the k8s_exec from community.kubernetes to do this:</p>

<pre><code>- name: k8s_exec Execute {{ script }} {{ script_args }} command in pod {{ the_pod }} 
  k8s_exec:
    namespace: "{{ meta.name }}"
    pod: "{{ the_pod }}"
    command: "{{ script }} {{ script_args }}" 
  register: call_result
  when: the_pod is defined

- name: The result of running {{ script }} {{ script_args }} in {{ the_pod }} 
  debug:
    var: call_result
</code></pre>

<p>But I get the following:</p>

<pre><code>--------------------------- Ansible Task StdOut -------------------------------

<p>The role has all the correct permissions (verbs: create, get) for pods/exec. I added second explicit <strong>apiGroups</strong> block of permissions; originally it was only the first one. Does not make any difference though.</p>

<pre><code>apiVersion: rbac.authorization.k8s.io/v1
kind: Role
metadata:
  creationTimestamp: null
  name: my-operator
rules:

<p>What am I missing?  </p>

<p>Thanks in advance</p>

<p>I have discovered the problem, there was a typo in the value of <code>{{ meta.name }}</code>.</p>
