Ask HN: How is Gitlab.com deployed and how does Gitlab upgrade Gitlab.com?

1 pointsahilarora5352 comments

There are a couple of ways to install and deploy Gitlab server which have been mentioned here: https://about.gitlab.com/installation/ . I am curious to know which of these methods do Gitlab itself use to host Gitlab.com and how does it upgrade the current version of Gitlab while ensuring no downtime.

GitLab.com is using the omnibus-gitlab package and it is configured in the HA configuration as per docs in https://docs.gitlab.com/ee/administration/high_availability/... . The actual update is being done using the directions in https://docs.gitlab.com/omnibus/update/README.html#multi-nod.... We use a custom built tool to enforce that zero downtime upgrade and the tool is in https://gitlab.com/gitlab-org/takeoff/ .

I do have to note that the tool is something we use temporarily as we are working towards refactoring part of infrastructure towards Kubernetes.

This is very helpful. Thank you very much. Is it also documented somewhere the problems you face when using Omnibus packages, and why you are planning on shifting to Kubernetes?
