Starting Place (for esbuild environments)

[kobaltz]

Just wanted to share my docker-compose.yml file and Dockerfile that I use for development whenever I'm making new Rails applications. My preferred way is to use esbuild, so these are tailored to that. Hopefully it can be of some use.

# Dockerfile.dev
ARG RUBY_VERSION
FROM ruby:$RUBY_VERSION

RUN apt update -qq && apt upgrade -y
RUN apt install -y build-essential
RUN apt install -y postgresql-client
RUN curl -sL https://deb.nodesource.com/setup_19.x | bash -
RUN curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | apt-key add -
RUN echo "deb https://dl.yarnpkg.com/debian/ stable main" | tee /etc/apt/sources.list.d/yarn.list
RUN apt update -qq
RUN apt install -y nodejs yarn
RUN gem update --system
RUN gem install bundle

WORKDIR /app
RUN echo 'gem: --no-rdoc --no-ri >> "$HOME/.gemrc"'

COPY Gemfile Gemfile.lock ./
COPY package.json yarn.lock ./

RUN bundle install -j $(nproc)
RUN yarn install

# docker-compose.yml
version: '3.8'
x-base: &base
  build:
    context: .
    dockerfile: ./Dockerfile.dev
    args:
      RUBY_VERSION: '3.1.3'
  stdin_open: true
  tty: true
  volumes:
    - .:/app:cached
  environment:
    - DATABASE_URL=postgres://postgres:postgres@postgres:5432
  depends_on:
    - redis
    - postgres

services:
  app:
    <<: *base
    command: bin/rails server -p 3000 -b 0.0.0.0
    ports:
      - '3000:3000'

  css:
    <<: *base
    command: yarn build:css --watch

  js:
    <<: *base
    command: yarn build --watch

  # sidekiq:
  #   <<: *base
  #   command: bundle exec sidekiq -C config/sidekiq.yml

  redis:
    image: redis:latest
    restart: always

  postgres:
    image: postgres:14-alpine
    volumes:
      - postgres:/var/lib/postgresql/data
    environment:
      - POSTGRES_PASSWORD=postgres
    ports:
      - 5432

volumes:
  postgres:

Additionally, I also modify the bin/dev with docker compose up

# bin/dev
#!/usr/bin/env bash

docker compose up
