# ANSIBLE

## How to proceed

For each machine, **one by one** do:
  - Check that cluster is healthy
    - Check garage
      - check that all nodes are online `docker exec -ti xxx /garage status`
      - check that tables are in sync `docker exec -ti 63a4d7ecd795 /garage repair --yes tables`
      - check garage logs
        - no unknown errors or resync should be in progress
        - the following line must appear `INFO  garage_util::background > Worker exited: Repair worker`
    - Check that Nomad is healthy
      - `nomad server members`
      - `nomad node status`
    - Check that Consul is healthy
      - `consul members`
    - Check that Postgres is healthy
  - Run `ansible-playbook -i production.yml --limit <machine> -u <username> site.yml`
  - Run `nomad node drain -enable -force -self`
  - Reboot
  - Run `nomad node drain -self -disable`
  - Check that cluster is healthy (basically the whole first point)
