# Docker
To setup webpacker with a dockerized Rails application is trivial.
First, add a new service for webpacker in docker-compose.yml:
```Dockerfile
version: '3'
services:
webpacker:
build: .
env_file:
- '.env.docker'
command: ./bin/webpack-dev-server
volumes:
- .:/webpacker-example-app
ports:
- '3035:3035'
```
add nodejs and yarn as dependencies in Dockerfile,
```dockerfile
FROM ruby:2.4.1
RUN apt-get update -qq
RUN curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | apt-key add -
RUN curl -sL https://deb.nodesource.com/setup_8.x | bash
RUN echo "deb https://dl.yarnpkg.com/debian/ stable main" | tee /etc/apt/sources.list.d/yarn.list
RUN apt-get install -y nodejs
RUN apt-get update && apt-get install -y yarn
# Rest of the commands....
```
and create an env file to load environment variables from:
```env
NODE_ENV=development
RAILS_ENV=development
WEBPACKER_DEV_SERVER_HOST=0.0.0.0
```
Lastly, rebuild your container:
```bash
docker-compose up --build
```
