With this post, I’d like to start a series of CI-related tips, targeted mostly at GitLab, since that’s my go-to tool for things CI/CD-related. I’m sure most of them could be easily applied to other CI systems, though. While GitLab does a great job at many things (repository hosting and related stuff, like MRs, pipelines, issue boards, etc.), it sometimes lacks more specialized features in some areas. With heavy usage of pipelines in my projects, I often had to look for workarounds and smart tricks.
