Salt is used for deployment. Configuration can be found in the rOPS repository.
Keys
Master
master.pub: 67:8b:e6:b2:7b:73:5b:f1:50:f4:48:38:9a:4c:1c:31:e1:b7:6e:eb:9f:47:98:40:1f:53:29:9e:86:bb:83:38
This fingerprint should be used by minions in the `master_finger` value in configuration file.
It can be updated running salt-call --local key.finger from Complector.
Troubleshoot
Request timeout
- Symptoms on master
- The minion doesn't reply with job result
- Symptoms on minion
- When running through
salt-call, output showsSaltReqTimeoutError, retrying. (1/7). - Possible cause and solutions
- The master key has expired on the minion: remove it on the minion with
rm /etc/salt/pki/minion/minion_master.pub. If you can repro faithfully a scenario with this issue, add more details at https://github.com/saltstack/salt/issues/46923
Lessons learned
UIDs and GIDs should be unique
UIDs and GIDs are created autoincrementally by the OSes, so it's very easy to have two different usernames using the same uid on two machines. To avoid that, every user.present and group.present Salt state should specify the uid explictly. To avoid to reuse one, document it in rOPS: UIDs and rOPS: GIDs.
