# Rails 6 Docker Alpine

Docker image size

```sh

$ docker images

REPOSITORY                                 TAG                       SIZE

blitz_web                                  latest                    390MB

```

### Steps

1. Clone & Create

```sh

git clone [email protected]:zazk/Rails-6-Docker-Alpine.git

```

Create a new Rails application under the repository directory

```sh

cd Rails-6-Docker-Alpine

rails new . --webpack --database=postgresql

```

2. Configure:

Modify your database configuration to use the postgresql container configuration:

```yaml

default: &default

  adapter: postgresql

  encoding: unicode

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

  host: db

  username: postgres

```

Remove check Yarn

```yaml

# ./config/environments/development.rb

# Disable Yarn Check

config.webpacker.check_yarn_integrity = false

```

3. Build the project:

```sh

docker-compose build

```

4. Create the database and run the migrations:

```sh

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

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

```

5. Run the app:

```sh

docker-compose up

```

Visit your application

```

http://localhost:3000

```

### Troubleshooting

1. If you have probles with `pg` gem you should install Postgres before. On Mac `brew install postgres`

2. Ruby Version `2.5.3`
