This project was inspired by xtity/hello-docker-rails.

Hello-docker-rails is a docker container for expirement with a rails docker container. This container requires an instance of mysql to connect to.

Environment variables

In addition to the default rails environment variables the following variables might be useful:

Variable Meaning Default

MYSQL_PASSWORD Password used to login to mysql
MYSQL_HOST Host where mysql is located
MYSQL_PORT Port of mysql 3306
RAILS_ENV Rails environment (Note: this container 404s in production) development
SECRET_KEY_BASE Used by rails to verify the integrity of signed cookies (Must be changed in production systems) 3776e3901...

Getting started using docker

To use this container with docker first install docker. See docker documentation for details

#create network
docker network create hello-rails

# Run Mysql Server
docker run -p 3306 -d --network=hello-rails --network-alias=db -e MYSQL_ROOT_PASSWORD=password --name hello-rails-db mysql

# Run app server
docker run -it -p 3000:3000 --network=hello-rails -e MYSQL_USER=root -e MYSQL_PASSWORD=password -e MYSQL_HOST=db --name hello-rails benjamincaldwell/hello-docker-rails:latest
