I can reproduce this by running the container manually:

$ docker run -it quay.io/ansible/awx-ee  /bin/bash
...
bash-4.4$ ansible localhost -m known_hosts -a 'name=example.com key="example.com ssh-rsa AAAAGIBBER" state=present'
[WARNING]: You are running the development version of Ansible. You should only run Ansible from "devel" if you are modifying the Ansible engine, or trying out features under development.
This is a rapidly changing source of code and can become unstable at any point.
[WARNING]: No inventory was parsed, only implicit localhost is available
localhost | FAILED! => {
    "changed": false,
    "msg": "Failed to write to file /home/runner/.ssh/known_hosts: [Errno 2] No such file or directory: '/home/runner/.ssh/tmpazpezdx9'"
}

Seems to be a bug of the known_hosts module, actually

[chrismeyersfsu]

I think the action item here is to pre-create the /home/runner/.ssh directory in the container so that known_hosts file creation does not fail.
