I need to use a custom docker image for continuous integration in Gitlab, especially as I need to embed custom SSL certificate in it, and would rather include some packages I need each time than installing them every time.
I know how to build a Docker image, and I read about the
image property in
.gitlab-ci.yml to choose which Docker image to choose, but I cannot find documentation about which is the correct starting point for a Docker CI image.
Do you know where I can find a base Dockerfile for a Docker-CI image?
