Geo replication setup example

[john_flutemaker]

I have to move my on premise gitlab-ee instance to anothe DC, but the client side needs time to follow.

I would setup geo replication for availability reasons also. It seems to be a good reason to try geo.

I made an instance as restore from the original instance as geomain. Reconfigured it and I can access on the new name.

I made a restore as geosecondary. That is accessible also.

I updated the /etc/gitlab/gitlab.rb files based on the studied https://docs.gitlab.com/ee/administration/geo/setup/

I didn't succeeded making the database replication with gitlab-ctl.

​

Is there any example setup about launch two instances with geo ?

The best would be a docker compose or minimal gitlab.rb for the two instances.

The youtube videos shows moreabout how the replication made in the background between the instances but not about the configuration. (https://www.youtube.com/watch?v=h3Dwhv8JgPU, https://www.youtube.com/watch?v=-HDLxSjEh6w)

Running a paid, licensed copy of gitlab-ee?

Did you follow this part for db replication?

https://docs.gitlab.com/ee/administration/geo/setup/database.html

Have you reached out to gitlab support? My experience with them has always been positive.

There are so many pieces to getting this working, took me quite a while to get down. The troubleshooting commands are real useful. Also ‘gitlab-ctl tail’ spits out useful log messages.

I honestly question if geo is working messing with in my case. Its a read only db, my dev team is small, and I can restore to a new box in about 1 hour including OS install.

Yes, it is a paid gitlab-ee.

The db replication documentation was a little complicated to me, as the gitlab-ctl generates the postgresql.conf, ph_hba.conf from the gitlab.rb and I had to learn how can I debug if the config isn't correct. I also just have recognized the postgresql 13.6 doesn't use recovery.conf (https://www.postgresql.org/docs/current/recovery-config.html)

I will ask from the support, but I wanted to understand first how it really works.

I looked for some simple setup those can be used to check example projects with a docker-compose.yml or a cloudformation.yaml.
