This project is a helper tool to easily create new Rails 8 applications without installing Ruby, Rails, or dependencies on your local machine.

• Docker installed: https://www.docker.com/get-started

1. Create a folder with your desired project name, for example:

mkdir new-project && cd new-project

2. Generate project

Use the variable PROJECT_PATH to map a volume with the container.

Exemple:

make build generate ARGS="--database=postgresql --skip-bundle --skip-javascript" PROJECT_PATH="./new-project"

If you prefer to run manually with Docker.

-v $(pwd)/my-project:/app: mounts your local my-project directory into the container at /app.

-w /app: sets the working directory inside the container, so the rails new command will be executed inside the /app folder.

docker run --rm \
  -v $(pwd)/my-project:/app \
  -w /app \
  joaopedrolucatto/rails-project-generator:latest \
  rails new . --database=postgresql --skip-bundle --skip-javascript
