A pretty simplified Docker Compose workflow that sets up (Ruby, Redis, PostgreSQL) network of containers for local ruby development.

Ports used in the project:

To get started, make sure you have Docker installed on your system and Docker Compose, and then clone this repository.

1. Clone this project:

   git clone https://github.com/supermavster/docker-ruby-on-rails.git

2. Inside the folder docker-ruby and Generate your own .env to docker compose with the next command:

   cp .env.example .env

3. You need Create or Put your laravel project in the folder source; to create follow the next instructions Here.

4. Build the project whit the next commands:

   docker-compose up --build

The configuration of the database must be the same on both sides .

# .env
# Develop Mode
RAILS_ENV=development

# Postgres
POSTGRES_HOST_AUTH_METHOD=trust

# Database Env
DATABASE_NAME=rails_development
DATABASE_USER=supermavster
DATABASE_PASSWORD=password
DATABASE_HOST=database

# Redis data
REDIS_HOST=redis

# source/.env
# Develop Mode
RAILS_ENV=development

# Postgres
POSTGRES_HOST_AUTH_METHOD=trust

# Database Env
DATABASE_NAME=rails_development
DATABASE_USER=supermavster
DATABASE_PASSWORD=password
DATABASE_HOST=database

# Redis data
REDIS_HOST=redis

The only change is the DB_HOST in the source/.env where is called to the container of database:

# source/.env
DB_HOST=database

Please check the file database.yml with the next values:

default: &default
  adapter: postgresql
  encoding: unicode
  pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 5 } %>
  host: database
  username: postgres
  password: 

development:
  <<: *default
  adapter: postgresql
  encoding: unicode
  database: rails_development
  username: postgres 
  password: password
  pool: 5
  host: database
  

To Down and remove the volumes we use the next command:

docker-compose down -v
