This repository contains a basic Dockerfile and Docker Compose templates for running Spree-based applications.

The Dockerfile is based on latest Ruby image, it also installs required dependencies for the application (Yarn, PostgreSQL libraries, ImageMagick).

Included Docker Compose creates a two containers that can be used in development or test deployments: one for Spree and one for PostgreSQL.

1. Move the contents of this repository to the root of your project

2. Configure database access

By default, the hostname of the database is postgres and the port is 5432. To make your Rails application connect with it you can:

• use the DATABASE_URL environment variable through envvars defined in the .env file

3. Build the images:

$ docker-compose build

The version of the bundler included in the alpine image (1.17.2) may be different than the bundler used in your project. You can find the right version in the BUNDLED_WITH section of your Gemfile.lock.

You can make it use your version by passing it as a build argument when running docker-compose build:

$ docker-compose build --build-arg BUNDLER_VERSION=<YOUR_BUNDLER_VERSION>

or place it directly in the environment of the spree service in docker-compose.yml:

spree:
  build:
    context: .
    args:
      BUNDLER_VERSION: 2.1.2

Since the default compose uses the build: context syntax you need to explicitly add the context path.

The image also uses Ruby 2.6.6 by default. If you need another version for your project you can set it identically to how you set BUNDLER_VERSION:

$ docker-compose build --build-arg RUBY_VERSION=<YOUR_RUBY_VERSION>

or change docker-compose.yml:

spree:
  build:
    context: .
    args:
      RUBY_VERSION: 2.7.0

4. Create the databases

$ docker-compose run spree rails db:create

5. Load the schema

$ docker-compose run spree rails db:schema:load

6. Seed the database

$ docker-compose run spree rails db:seed

7. Precompiling assets If you wish to precompile assets you can do so by running:

$ docker-compose run spree rails assets:precompile

To run the application simply execute:

$ docker-compose up

You should now be able to visit http://localhost:3000 in your browser.
