# rails5-docker-alpine

This is a very lightweight Docker image based on Ruby Alpine to run a Rails 5

application.

I also provide a docker-compose file to run your project using a PostgreSQL

database.

## Trying out the image

Clone the repository:

```sh

git clone [email protected]:pacuna/rails5-docker-alpine.git

```

Create a new Rails application under the repository directory

```sh

cd rails-docker-alpine

rails new . --database=postgresql

```

Modify your database configuration to use the postgresql container configuration:

```yaml

default: &default

  adapter: postgresql

  encoding: unicode

  # For details on connection pooling, see rails configuration guide

  # http://guides.rubyonrails.org/configuring.html#database-pooling

  pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 5 } %>

  host: db

  username: postgres

```

Build the project:

```sh

docker-compose build

```

Create the database and run the migrations:

```

docker-compose run --rm web bin/rails db:create

docker-compose run --rm web bin/rails db:migrate

```

Run the app:

```sh

docker-compose up -d

```

Visit your application at localhost:3000.

Tested with:

- Ruby 2.5.1p57 (2018-03-29 revision 63029) [x86_64-linux]

- Rails 5.2.2 (to create the new application)

- Docker version 18.09.0, build 4d60db4

- docker-compose version 1.23.1, build b02f1306
