Scala training project

Project Dependencies

• play json
• jdbc (used by Scala in the Play Framework)
• evolutions
• postgres
• doobie

Running the Application

1. Install Docker and postgresql on your machine, if not installed already.
2. Launch Docker (this app expects the latest postgres alpine)
3. Run the database through terminal commands
   1. Create the docker container (after creation you can run/press play on the container inside the desktop app):
   2. docker run --name pass-bakery-postgres -e POSTGRES_USER=user -e POSTGRES_PASSWORD=pass -e POSTGRES_DB=pass_bakery_db -p 5432:5432 -d postgres:alpine
   3. Access the docker postgres database (enter pass when promtped):
   4. psql -h localhost -p 5432 -d pass_bakery_db -U user
4. Launch the app on a separate terminal tab (command+T), navigate to the project root, and run with sbt run
5. Apply evolutions when prompted at any endpoint connection

Docker Cheatsheet

1. ONE TIME! Download latest postgres alpine image: docker pull postgres:alpine
2. Create/start the Docker container: docker run --name pass-bakery-postgres -e POSTGRES_USER=user -e POSTGRES_PASSWORD=pass -e POSTGRES_DB=pass_bakery_db -p 5432:5432 -d postgres:alpine
3. Access the db: psql -h localhost -p 5432 -d pass_bakery_db -U user and enter pass when prompted for the password
   1. IMPORTANT: if you cannot access the container from the terminal with this command, stop the docker container (easy through the desktop app), delete the container, then start from step 2 again (docker run...)
4. Additional Notes:
   • Check if pass_bakery_db exists by listing databases with \l
   • If needed, connect to the database with \c pass_bakery_db
   • View tables with \d
