Docker-in-Docker in Gitlab Runners
- twooster 9y agoGitlab gets a lot of love around here on Hacker News. I'm sure there's a lot of people setting up their own servers and maybe running into some questions/problems around setting up Docker-in-Docker style builds. There's some information out there, but I decided to put together a comprehensive-ish guide that maybe could be of use. Let me know if you have any questions!
- inchevd 9y agoThis looks like a nice write up guide, was just wondering here, how do you keep docker builds tags from clashing if they're all running on the same Docker instance?
- twooster 9y agoSadly they have to operate cooperatively. :/ I've taken great pains to prefix all of my builds with "${CI_JOB_ID}" and add a `clean` step at the end to tear down all created images. It's not perfect, but it works well enough in a trusted environment.
