I'm currently using gitlab-ci to generate docker images for some repositories, however i dont feel as though this solution is as reliable as it should be.
I can forsee a issue with multiple builds happening close together and build #100 overwriting the newly built docker image produced by build #101, if for whatever reason jobs dont finish sequentially (eg: multiple build hosts, etc...).
Currently the tags i'm hoping to use follow this pattern:
The crux of the question is as follows:
- How do other services solve this problem? (presumibly running builds sequentially per branch?)
- How should this issue be resolved in gitlab environments in a totally watertight manner
I understand this problem would go away if i use the SHA of the commit for the build tag, but i'd like to stick to the branch name for the following reasons:
- orphaned / old images will be grabage collected by the docker registry
- branch name is easier to use
