What is this?

This is a repository containing the Ansible configuration for the laptop-fleet of the Chaostreff Osnabrück.

Adoption

As the very first step, you have to install your own key onto the machines (hopefully also part of the authenticated_keys for the playbook). Do that via:

ssh-copy-id user@ctreffosXX

Preperation

. envsetup.source # to configure which inventory to use
ansible -m ping all # just to make you can reach them all

Usage

ansible-playbook site.yml --ask-become-pass

Block standby (during rollouts)

ansible-playbook power-block.yml --ask-become-pass

Troubleshooting

The inventory is using the mDNS advertised hostnames of the machines. While this saves us from configureing the inventovry with fixed IPv4 addresses, it may lead to problems, if the mDNS/WiFi-connection is not working properly. I would recommend you to start with the power-block.yml-playbook and rerun it until all machines are reachable.

Contribution guidelines

• Never use run_once: true, because due to the strategy free, the task may be completed multiple times on different hosts, as they may start at different point of time.
• Never use reboot or other power actions during a run - as power-block.yml will retrict them and may cause the playbook to get stuck.
