Trainguard Duty

Trainguards are vanguards for the CI Train. Trainguards are usually Landing Team members that have the required permissions and knowledge to drive the train, e.g. assign silos, publish silos, perform reconfigurations etc. They are also the first person of contact whenever there is a problem related to silos or the train in overall. Not every trainguard will be able to resolve all your problems, but they will know how to forward the issues to the right people.

Trainguards are different from CI-team vanguards. Most trainguards are not even part of the CI team, so for any non CI Train issues please contact the CI vanguard instead.

Available trainguard

There is usually one or two trainguards always present for every timezone. You can find the current trainguard on duty by checking the topic on the #ubuntu-ci-eng IRC channel. If no particular person is listed, say 'trainguards' on the channel to address all available people on duty. Every possible trainguard gets highlighted then.

Trainguard duty

There must be at least one trainguard available per timezone to ensure proper CI Train service. Trainguard duty is set by the Landing Team Lead (or the person in charge in his absence). In case of one person on duty, the Landing Team Lead must select an emergency stand-by - a person that could jump into duty in case of an emergency.

Trainguard absence

If a the current trainguard needs to leave, he must select a replacement to ensure that his timezone is covered. In the unlikely case when the selected trainguard needs to urgently leave his post leaving no coverage for the CI Train, the emergency stand-by person takes over trainguard duty. The Landing Team Lead or anyone else from management should in such a case inform the stand-by to handle CI Train requests temporarily.

The order of trainguard selection in case of absence:

1. If current person on duty is out, the next person from the main trainguard list is selected
2. If no one from the main trainguard list is available, first available person from the emergency stand-by list is selected
   • In this case the Landing Team Lead should be informed afterwards to somehow fill in the missing gap
3. If none of the above is available, please emergency-contact the current Landing Team Lead (mup, text message, phone-call)
