Please ensure you are using Docker Compose V2. This project relies on the docker compose command, not the previous docker-compose standalone program.
Check your docker compose version with:
% docker compose version
Docker Compose version v2.10.2
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 bundle update
docker compose up --build
(adjust tags as needed)
with BuildKit
DOCKER_BUILDKIT=1 docker build --tag rails-on-docker --load .
Test the image can be used and Rails starts up, use a fake key for testing purposes only:
docker run --rm --env SECRET_KEY_BASE=dummy rails-on-docker
docker build --tag rails-on-docker .
