Dockerizing DRF Cinema

Read the guideline before start
Useful link about theory (without Celery & redis of course)

Task:

Here, you need to fully dockerize this existing DRF project Cinema. You need to make your service fully independent of your local machine. So the only requirement to run your project is Docker.

Task requirements:

Use .dockerignore for ignoring unnecessary stuff in your images;
Use Dockerfile for building app image with DRF application;
Use docker-compose.yml file for managing multiple services (containers) at the same time;
Switch to PostgreSQL database instead of SQLite using official docker image;
Implement wait_for_db management command, which waits for the database to be available. So your services won't throw any errors during the docker-compose up command;
Make your docker images as thin as possible;
Use good practices of how to handle media, static files & volumes with docker.

How to check, that task is done:

Run docker-compose up command, and check with docker ps, that 2 services are up and running (here check, that app is always waiting for db using wait_for_db command);
Go to 127.0.0.1:8000/api/ and check project endpoints via DRF interface (image uploading for sure);
Create new admin user. Enter container docker exec -it <container_name> bash, and create in from there;
Run tests using different approach: docker-compose run app sh -c "python manage.py test";
If needed, also check the flake8: docker-compose run app sh -c "flake8".
If everything is working fine - you are ready to push your code :).
