Description

Motivation

See #160646 and #161381

Acceptance criteria

  • AC1: The backend and/or test code can point better to likely causes of an error
  • AC2: Similar future issues are prevented with better CI checks

Suggestions

  • Monitor contents of the mine to better understand when it breaks and why
  • Implement sanity checks on the worker to check for proper peer configuration
  • Change the MTU-size check in the test distribution so make the error message more clear in case not even the smallest MTU-size works (e.g. "The network connection within the SUT does not work at all." and maybe for tap-based tests "Check the MM-setup, e.g. GRE tunnels")
  • Get rid of the mine completely for "workername" <-> IP lookup
    • Problem: Currently the pillar-data does not contain the FQDN of the other workers.
    • We already have "## FQDN: …" in many cases so it would be easy to make that a mandatory key for all, at least the ones where we expect that the tap class should be usable

WARNING

  • Do not touch the key of a worker in workerconf.sls - a lot of other states depend on it!
