Containerize application

[JamalG16]

As a developer, I would like to containerize the application.

Technology to be used is docker.

• Create Dockerfile for /frontend
• Create frontend service in docker-compose.yaml
• Create Dockerfile for /backend
• Create backend service in docker-compose.yaml
• Update README with instructions on how to run the application with docker.

IMPORTANT NOTES FROM SETUP:

• run docker-machine ip default to get the ip-address of docker machine (if you still want to use localhost, you must enable port forwarding. If you use docker toolbox, you can follow this: https://stackoverflow.com/a/45822356). Currently, project is setup assuming port forwarding is put in place as the phone must be connected to same wireless network as expo.
• create and build container and build/rebuild services docker-compose up --build from project root
• create and build container docker-compose up from project root
• Stop and remove containers, networks, images, and volumes, run docker-compose down -v from project root
• To delete docker containers and optionally delete cache docker system prune -a (remove -a if you do not want to delete cache)

DISCOVERED BUGS:

• When trying to run the application, animated node type param not supported natively is an error that occurs if node modules are downloaded from within the docker virtual machine. However, if node_modules are based on the local node_modules (with the use of volumes), then it works. No solution was found for this issue and many hours of debugging were spent to no avail. Ultimately, even though this is counter intuitive, node_modules will have to be installed locally by running npm install in the /frontend directory of the project, then docker-compose up can be ran to successfully load the application. The issue seems to be related to the Drawer component, as it requires the react-native-reanimated package, which seems to be the root of the issue.
  RESOLVED by upgrading packages and dependencies

• Polling/hot reloading for the frontend is not functional. Polling dependencies such as CHOKDIR were integrated and tested, but to no avail. The environment was modified to attempt fixing this, but to no avail either. Would require more investigation to pursue full development using docker.
