# Rails App with PostgreSQL and Docker
## Description
> This repository contains the source code for a Ruby on Rails application configured to use PostgreSQL as the database and run within Docker containers.
## Prerequisites
Before you begin, ensure you have the following installed on your machine:
- Docker
- Docker Compose
## Getting Started
### Step 1: Create a New Rails Application
```
rails new myapp --database=postgresql
cd myapp
```
### Step 2: Add PostgreSQL as the Database
```
# Gemfile
gem 'pg', '>= 0.18', '< 2.0'
```
```
bundle install
```
### Step 3: Install the dockerfile-rails Gem
```
# Gemfile
group :development do
gem 'dockerfile-rails', '~> 1.6', '>= 1.6.17'
end
```
```
bundle install
```
### Step 4: Generate Docker and Docker Compose Files
```
bin/rails generate dockerfile --compose --postgresql
```
### Step 5: Set Up the .env File
```
touch .env
```
Add the following content to the .env file:
```
POSTGRES_USER=postgres
POSTGRES_PASSWORD=yourpassword
POSTGRES_DB=myapp_development
DATABASE_URL=postgres://postgres:yourpassword@db:5432/myapp_development
```
```
rails secret
```
### Step 6: Build and Run the Docker Containers
```
docker-compose build
docker-compose up
```
### Final Steps
```
docker-compose run web rake db:create db:migrate
```
## Generate a Secret Key Base:You can generate a new secret key base using the Rails command:
