Feature: a more efficient way to execute tests from docker-compose

[marcellodesales]

👍 Improvements

• Setting up a custom name of the WORKDIR to better document which exercise the user is working on /google/trainings/haskell-101/00_setup
• Properly implement a better Docker Cache for the haskell dependencies to avoid re-evaluating/downloading of the haskell dependencies when running stack run
  • Since the execution was placed in the container level, the dependencies were fetched at every execution
  • Added a deps Makefile task to be executed
• Documenting the way to execute a terminal from docker-compose
  • That way, users learning haskell can execute the commands internally to the image
• Allow users to solve the exercises from within a docker container
  • vim is now installed in the Docker image

NOTE: This is a solution only for haskell_101. I can submit an additional PR for haskell_202, with more generalizations, if this PR gets to be merged.

Another important point is when debugging, users can provide better logs for debugging what's going, which training they are doing, etc...

🐛 Bugfixes

🩹 Preserved Container coloring - when in docker-compose

• This is a known issue when running containers whose logs are colored
  • https://github.com/docker/compose/issues/2231#issuecomment-425135985
• As the underlying testing "framework" built in haskell explicitly added to get colored test results
  • Without them, that may also be a problem for some (me included)

⚡ Performance improvements 🐳

Created a single Makefile from a copy of setup, made it pull dependencies. That way, it's simpler for users to just run the docker container without having to re-run the entire process over and over again. Instead, taking advantage of the docker caching system by declaring a new layer in the Dockerfile to call the dependencies only.

💩 Inefficient runs

All the time running the current code the build pulls everything over and over again. That's just too much after a while. We have 2 options:

1. Create a base docker image for everything
2. Reuse the same Dockerfile for the same docker image
   • Updating the Makefile with a new task to get the dependencies
   • Run the dependencies for each of them

Since dependencies don't change often, the docker image cache works perfectly to just pull the same dependencies for codecolab's functions and the execution is left as is. This time, faster as it takes advantage of the dependencies already built into the docker image instead of the docker container (that is, the current version).

🔉 Docker Image: Build with Cached Dependencies

• Note that only the first project shows a full resolution of the dependencies at step ls -d */ | awk '{ print $1 }' | xargs -I {} make -C {} deps
  • The execution of the dependency resolution was added to a consolidated Makefile in the root of the dir.
• All the other executions are shown as CACHED

👍 Faster solution: Docker Containers only compile and run binaries

• Since stack dependencies are resolved at docker image build-time, the process that executes stack run runs faster without pulling dependencies at every code change.
  • This is a reflection of the line COPY . . that is originally used in Dockerfile

• All the dependencies were fetched during the docker image build
• We don't see the previous download of the dependencies anymore
  • Proved by Docker's cache system
  • Logs show CACHED for every entry to the areas when it is executed
  • Forcing the rebuild will NOT pull the dependencies again
