I had several objectives for this course: - to go over REST and API with theory and practice; - to see how to use Swagger; - to see Docker with a bit of practice as a bonus. I'm fully satisfied with the REST and API part because we took the time to practise. The time devoted to Swagger was correct in terms of theory and practice. Unfortunately, the Docker part remained very theoretical due to lack of time. Overall, I'm satisfied.

like many training courses, lack of time to see all the subjects but quality training

I think 3 days is too short for such a big subject. Having an extra day would allow us to go into a bit more depth on all the subjects covered in the course. The trainer takes the time to answer our questions and to talk with us, which is very pleasant if you want to feel that you're making progress. Perhaps we could add a little more detail to the exercise descriptions, to make sure we grasp all the concepts covered.
