I have an odd issue with gitlab-runner. It’s something only happens once in a while, and has been occurring over the past few years.
We have a self hosted GitlLab instance. I have two separate projects on that instance that use gitlab-runner to perform tasks on the same vm. One runner is for deploying code, the other runs a docker container with my backup software.
Both runners are use the shell executor.
What happens is that when the backup job is running, sometimes the code deploy will not run. I have not pinned down if the backup job always blocks the deploy job, or not.
I thought that gitlab-runner was supposed to be able to run each instance at the same time. Is that not the case?
Any feedback will be appreciated.
Current version of gitlab-runner is 12.10.1.
