Ouroboros

https://github.com/pyouroboros/ouroboros

Ouroboros will monitor (all or specified) running docker containers and update them to the (latest or tagged) available image in the remote registry.

Install the role via:

cd ~/community && sudo ansible-playbook community.yml --tags ouroboros

The Ouroboros role will import ouroboros.env into /opt/ouroboros for persistent configuration via ENV variables. See https://github.com/pyouroboros/ouroboros/wiki/Usage for available variables. Default values populated by the role are:

SELF_UPDATE=true
CLEANUP=true

Run the command to install the role again for any changes to ouroboros.env to take effect.
