I’m new to Docker and a little confused on how to handle large builds that use multiple dockerfiles to create multiple dependent images. Maybe I am going about this all wrong. While I have tried to make my question as clear as I can, it still may not be clear. Sorry if it is not.
I currently have a setup that builds many different dependencies in four different docker files. Each dockerfile builds upon the previous. Below I give a general idea of what the different dockerfiles do. I know that what I have below won’t create slim images, but this is just for testing so far and I will slim them down later.
At this point, any advice on how to better make use of Docker and how to construct more useful images would be appreciated.
