Ansible playground
==================
`Debian:stretch` based ansible playground. Spawn containers, allow passwordless root login for fun.
Scripts assume your public key is located at `$HOME/.ssh/id_rsa.pub`. Have fun.

## SSH into the container
Known host is added to `/dev/null` by the way so it won't spam your `known_hosts` file.
`bin/ssh 3`
```
Warning: Permanently added '[localhost]:32802' (ECDSA) to the list of known hosts.

## Dynamic Ansible inventory
Bash script fetches running container list and outputs list in Ansible's JSON format:
Example usage:
`ansible-playbook -i ansible/inventory playbook.yml`
Script output:
> {"Ansible":{"hosts":["78e45d91ae22.localhost","612ed77c432c.localhost","e3bb7c4a0fa9.localhost"]},"_meta":{"hostvars":{"78e45d91ae22.localhost":{"ansible_ssh_port":"32813","ansible_ssh_user":"root","ansible_connection":"ssh"},"612ed77c432c.localhost":{"ansible_ssh_port":"32812","ansible_ssh_user":"root","ansible_connection":"ssh"},"e3bb7c4a0fa9.localhost":{"ansible_ssh_port":"32811","ansible_ssh_user":"root","ansible_connection":"ssh"}}}}
