Are you suggesting gitlab ci isn't docker? All my pipelines are some docker variant. I'm not sure if you are just suggesting actions was done the right way with docker, but that's nothing special with gitlab ci. Can you clarify? You can even use your own docker repository with gitlab, though I'm unsure if that's something that only comes with EE (I haven't needed it yet, I just keep all my extras in the gitlab ci yaml file).
Sorry, I'm honestly not familiar with Gitlab CI. I was just originally mentioning how the use of Docker in Github Actions allowed for amazing flexibility, which I thought was cool.
What makes Gitlab CI a better or more polished API than Github Actions? At first glance they look very similar
Gitlab has a few different modes for its runner. One of them uses docker to run your script in a container. But you can also have shell executors which is more like Jenkins, for example. That can actually be better if what you're doing is building a lot of Docker images.
