Running with Docker

We strongly encourage Docker usage. With Docker, we can standardize the development environment, quickly rebuilding it whenever necessary without installing anything on the host machine.

A straight forward Dockerfile based on an official Ruby base image is provided. Also, the Docker Compose configurations provided, help considerably running the Docker commands.

You can have full control of the Docker Compose configs in your development environment, we provide a sample file, and just the environment variables are required.

$ cp docker-compose.override.yml.sample docker-compose.override.yml


After setting up the Docker Compose configuration, to set up the application, you need to run:

$ docker-compose run --rm web bin/setup

Running the application

Now that all setup steps are done, you only need to run the command below to get the application running:

$ docker-compose up

That's it! Just go to http://localhost:3000.
