SUMMARY

As of Ansible Core 2.15, the BIG-IP modules seem to try to connect to inventory_hostname, instead of what is defined in provider.

Running bigip_command with Ansible 2.15 and the cli transport results in a Name or service not known error when run with paramiko. With libssh, ssh connection failed: ssh connect failed: Failed to resolve hostname inventory_hostname (Name or service not known) error occurs.

Running the same playbook with Ansible 2.14 works OK.

Seems to be related to #2348 (Ansible 2.13 with libssh), which suggested setting $ANSIBLE_NETWORK_CLI_SSH_TYPE=paramiko, but that does not seem to work anymore.

The issue seems to be caused by paramiko connection now uses the correct source of data, a change to Ansible 2.15 which makes the paramiko connection plugin behave more like the libssh plugin.

STEPS TO REPRODUCE

Playbook:

---
- name: Test
  hosts: all
  gather_facts: false
  vars:
    provider:
     server: 127.0.0.1
     user: root
     password: secret
     validate_certs: no
     transport: cli
     server_port: 22
  tasks:
    - name: test
      bigip_command:
        commands:
          - show sys version
        provider: "{{ provider }}"

Run playbook with ansible-playbook -i localhost, -vvvvv playbook.yaml.

EXPECTED RESULTS

Ansible connects to the host defined in provider and runs the commands.

ACTUAL RESULTS

Ansible tries to connect to inventory_hostname which results in the following error when run with paramiko:

The full traceback is:
Traceback (most recent call last):
  File "/usr/lib/python3.9/site-packages/ansible/executor/task_executor.py", line 165, in run
    res = self._execute()
  File "/usr/lib/python3.9/site-packages/ansible/executor/task_executor.py", line 660, in _execute
    result = self._handler.run(task_vars=vars_copy)
  File "/runner/collections/ansible_collections/f5networks/f5_modules/plugins/action/bigip.py", line 90, in run
    out = conn.get_prompt()
  File "/usr/lib/python3.9/site-packages/ansible/module_utils/connection.py", line 200, in __rpc__
    raise ConnectionError(to_text(msg, errors='surrogate_then_replace'), code=code)
ansible.module_utils.connection.ConnectionError: [Errno -2] Name or service not known
fatal: [localhost]: FAILED! => {
    "msg": "Unexpected failure during module execution: [Errno -2] Name or service not known",
    "stdout": ""
}

You get the following error when run with libssh:
