c) enable plugin and start replication:

unzip gerrit.war
cp WEB-INF/plugins/replication.jar /tmp/
ssh -p 29418 pdx-wl-gerrit-1.web.someserver.org gerrit plugin install -n replication -</tmp/replication.jar
ssh -p 29418 pdx-wl-gerrit-1.web.someserver.org gerrit plugin ls

-------------------------------------------------------------------------------
replication                    v2.8       ENABLED  replication.jar

ssh -p 29418 pdx-wl-gerrit-1.web.someserver.org gerrit plugin reload replication

ssh -p 29418 pdx-wl-gerrit-1.web.someserver.org replication start --wait --all
Replicate compliance/tests to aricgardner.com, Succeeded!
----------------------------------------------
Replication completed successfully!

Thanks for the doc!
Also for dumb like me: the gerrit docker has a java version which doesn't support new ssh_config file format so:
Match host github.com != Host github.com

Thank you!
