To help the users of this exercise to learn how to use docker and where to get help when they are stuck in the real world, I have tried to create exercises that forces the user to look in documentation and experiment.
This means, that the exercise set is not a simple copy & paste exercise
Slides for Efficient Dockerfiles
Exercises for automated builds
If you are stuck in the exercises there is a branch called "i_need_to_cheat". This branch contains the solutions for most of the exercises.
These sides and exercises are build on top of giants!
