How to Run

git clone https://github.com/x1wins/rails-new-with-docker-compose.git
cd ./rails-new-with-docker-compose
./generate_rails_project.sh [YOUR_PROJECT]

It's Done.

Go to cd ../[YOUR_PROJECT] There are generated project.

Rails app and PostgreSQL container are already running.

Why?

Easy Generate Rails App Project with docker-compose.

No more sqlite with rails.

Start PostgreSQL for Production Ready with Docker.

Background

When I run command with $ rails new PROJECT with postgresql I realize struggle and tired that generate rails project files and setup database. If I got something wrong local environment such as rbenv, rvm on macOS or another OS. It's made me burnout.

docker-compose is perfect awesome developerment environment. When i generate rails project with docker-compose, i don't need any setup on local environment like ruby, rails version, database setup. docker-compose made easy setup rails project, database and another env.
