Please ensure you are using Docker Compose V2. This project relies on the docker compose command, not the previous docker-compose standalone program.
https://docs.docker.com/compose/#compose-v2-and-the-new-docker-compose-command
Check your docker compose version with:
% docker compose version
Docker Compose version v2.10.2
cp .env.example .env
docker compose build
docker compose run --rm web bin/rails db:setup
docker compose up
When the app is already running with docker-compose up, attach to the container:
docker compose exec web bin/rails c
When no container running yet, start up a new one:
docker compose run --rm web bin/rails c
docker compose run --rm web bin/rspec
docker compose run --rm web bundle update
docker compose up --build
docker build -f production.Dockerfile .
This app can be hosted wherever Ruby is supported and PostgreSQL databases can be provisioned.
NOTE: In production you will need to generate a secret with bin/rails secret and set it as the SECRET_KEY_BASE environment variable.
