I’m just wondering if there is a possibility to upgrade gitlab in a docker setup without downtime.
I guess with a reverse proxy an upgrade would just be:
- pull the new image
- spawn a container with the new image
- adjust the reverse proxy to forward requests to the new container once it is fully operational.
- stop and remove the container with the old image
A likely issue to me seems to be that the database is not run in a separate container. Therefore I would appreciate feedback from someone who might have more insight whether a zero downtime upgrade is possible with docker.
