Introducing Container Builder for Cirrus CI¶
When Cirrus CI was announced a few months ago Docker support was already pretty sophisticated. It was possible to use any existing Docker container image as an environment to run CI tasks in. But even though Docker is so popular nowadays and there are hundreds of thousands of containers created by community members, in some cases it’s still pretty hard to find a container that has everything installed for your builds. Just remember how many times you’ve seen apt-get install in CI scripts! Every such apt-get install is just a waste of time. Everything should be prebuilt into a container image! And now with Cirrus CI it’s easier than ever before!
