Dockerize project

[janivanhala]

Fill out dockerfiles and docker-compose correctly to create frontend <-> backend <-> database environment.

Ports handled correctly. Hope no hardcoded ports in backend/database.

Important database related:

• Create user for db with admin rights with docker. Default user only works with Neo4j-browser.

Docker installed and running. Then next command in project root folder:

# normal
docker-compose up
# force rebuild
docker-compose up --build

# shutdown
docker-compose down
# shutdown and remove volumes (mainly to reset database related stuffs)
docker-compose down -v 

Progress:

• App accessible at http://localhost:5173/ ... and maybe other ways, need to remove unwanted ways to access.
• Seems to have got it working, but problems with neo4j user/password (unable to set correctly, resets it to defaults). But works with defaults.
• All related ports are open to outside (like neo4j). Need to contain them in their own networks at some point.

Changed .env variable naming. It seemed to conflict with NEO4J_ stuff.

Neo4j community version only allows one user: 'neo4j'. Password is changeable.

Only frontend's port: 5173 open outside of docker environment. Also frontend can only communicate to backend and database can only communicate to backend. Connection isolation: Outside <-> Frontend <-> Backend <-> Database.

There are many things relating to "dev"-use, unsure if these need to be changed in the end.
