- 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

Run nomad node drain -self -disable
