Geo Frequently Asked Questions

What are the minimum requirements to run Geo?

The requirements are listed on the index page

Can I use Geo in a disaster recovery situation?

Yes, but there are limitations to what we replicate (see What data is replicated to a secondary node?).

Read the documentation for Disaster Recovery.

What data is replicated to a secondary node?

We currently replicate project repositories, LFS objects, generated attachments / avatars and the whole database. This means user accounts, issues, merge requests, groups, project data, etc., will be available for query.

Can I git push to a secondary node?

Yes! Pushing directly to a secondary node (for both HTTP and SSH, including git-lfs) was introduced in GitLab Premium 11.3.

How long does it take to have a commit replicated to a secondary node?

All replication operations are asynchronous and are queued to be dispatched. Therefore, it depends on a lot of factors including the amount of traffic, how big your commit is, the connectivity between your nodes, your hardware, etc.

What if the SSH server runs at a different port?

That’s totally fine. We use HTTP(s) to fetch repository changes from the primary node to secondary nodes.

Is this possible to set up a Docker Registry for a secondary node that mirrors the one on a primary node?

Yes. See Docker Registry for a secondary Geo node.
