Git

I switched to Gitlab when Github was bought by Microsoft. Call me extremist, stupid, and all the names you like, I personally felt the need to do it.
And quite honestly, I’m pretty happy with that choice, Gitlab is an incredibly useful suite, we use the community version at work and would never go back. But there’s one thing that’s pretty annoying with Gitlab, their documentation organization. Honestly it’s like they don’t want you to figure out how to do things. It’s often split into tens of various links and you end up reading issues discussions without really knowing if the feature you’d like is implemented or just an idea at that point.

With all the noise around those topics I would have imagined this one had been covered thousands of time, yet I did not find a single complete resource on this subject which I found to be a basic building block: pushing docker images from GitLab CI to the Docker Hub registry.

There’s actually an opened issue on Docker GitHub’s that’s sitting there for 3 years, and it really feels more like a political / strategic / commercial issue than a technical one. Point being, there’s no straightforward integration between GitLab.com and Docker Hub.
