I would like to use Ansible to manage ephemeral docker containers as SSH servers with password-challenge **for testing purposes.**

All containers are spawn from a single image, so they have the same SSH password.  
Is it possible to disable key authentication and use a single password for all destinations?

**_$ ansible -m ping all --ask-pass --su-user -vvvv_**

In ansible.cfg you can  
[defaults]  
host\_key\_checking= False

as env var: ANSIBLE\_HOST\_KEY\_CHECKING=0

or you can bypass sshpass by using paramiko as your transport `-c  
paramiko` in the command line (also settable in ansible.cfg and env)
