Hello,
We will switch the CI services from contint1001 (eqiad) to contint2001 (codfw). The maintenance is scheduled for Wednesday May 27th 9:30 CEST (7:30 UTC).
The maintenance window is TWO HOURS, but the migration will most probably be complete in a shorter time frame.
We previously tried the upgrade on May 11st which got rollbacked since I have missed the java 8 to 11 upgrade which turned out to be a deal breaker.
During the maintenance, CI will not be available: no tests will be run and events (code-review +2, rebase, new patchsets) will not be captured.
The beta cluster will NOT be automatically updated.
If a change has to happen on the configuration repositories:
* operations/puppet : locally run: - bundle update && bundle exec rake test or if you have Docker: - $puppet_dir/utils/run_ci_locally.sh
* operations/mediawiki-config : locally run: composer install && composer test
Then manually V+2 and Submit the change.
After the maintenance, Antoine will retrigger most events.
