Deploy multi-site plugin to gerrit1001 and gerrit2001
Closed, DeclinedPublic
Actions

Description

GerritForge have created a new plugin called "multi-site" this plugin allows you to have multiple gerrit masters. So with gerrit2001 being a master in addition to cobalt we can quickly fall over in case.

This plugin uses kafka to forward event's.

See https://groups.google.com/forum/#!topic/repo-discuss/A9dGOppvgGA and https://gerrit-review.googlesource.com/admin/repos/plugins/multi-site

Deploying:

  • Test on a test install using kafka too.
  • Once testing is complete and it works deploy to production.

Note this requires at least gerrit 2.16+

This can be deployed to prod (if there's kafka in prod). In my testing this worked really well (we only want replication from cobalt to gerrit2001 so we can easily fall over).

https://gerrit.git.wmflabs.org/r/c/testing/test/+/2161#message-556be9c19b4b882db5afefbee232ea1a092609ff replicated to https://gerrit.gerrit.wmflabs.org/r/c/testing/test/+/2161#message-556be9c19b4b882db5afefbee232ea1a092609ff using a mix of replication and multi-site.

Note this requires gerrit 2.16 to work.

It is really unlikely we will setup the multsite plugin though if we change our mind later we can always reopen this :)
