Kickass Development Environments with Docker (Edinburgh PHP, January 2016)

Docker, the hottest technology around at the moment. It swept the Ops world by storm in 2014, became mainstream in 2015, and now it’s set to dominate the developer world, in 2016.

Docker is a tool that allows you to package your application up into a single-runnable distributable binary - akin to the phar, but in Hulk mode. Docker allows you, a developer, to specify the exact environment your application needs to run, across development; test; staging; and production.

In this talk I will cover the creation of this utopian distributable and show you how to can compose your entire production infrastructure locally with only a small YAML file and without installing a single thing.

Lets say hello, to Docker.

  2. What is Docker? Docker allows you to package an application

    with all of its dependencies into a standardized unit for software development. docker.com
  3. The Docker Family • Docker • Docker Engine • Docker

    Registry • Docker Compose • Docker Machine • Docker Swarm
  4. Official Images http://hub.docker.com • php (5.5, 5.6, 7.0) • redis

    • memcached • elasticsearch • mysql • postgres • mongo • node • rabbitmq • …
  5. docker run -e APP_ENV=development -v .: /var/www -p 0.0.0.0:10000:80 --

    link elasticsearch:elasticsearch -- link postgres:postgres --link memcached:memcached edpug:1
  6. Abuse Docker testing-database-pdo: extends: service: testing-php-5.5 environment: - DATABASE_USER=root -

    DATABASE_PASS=testing - DATABASE_NAME=testing testing-database-mysql: extends: service: testing-database-pdo links: - mysql:mysql environment: - DATABASE_DRIVER=pdo_mysql - DATABASE_HOST=mysql - DATABASE_PORT=3306
  7. Base Image ONBUILD FTW # Dockerfile ONBUILD COPY . /var/www

    # docker-compose.yml application: image: base-image volumes: - .:/var/www
  8. Base Image NIGHTLY BUILDS cron / curl / wget /

    whatever! FROM your-company:base:latest FROM your-company:base:dev FROM your-company:base:prod
  9. Image Size Keep it Lean! RUN DEBIAN_FRONTEND=noninteractive \ apt-get update

    \ && apt-get install -y \ --no-install-recommends apache2 \ && rm -rf /var/lib/apt/lists/*
  10. volumes-from: - cache_and_logs cache_and_logs: - image: busybox - volumes: -

    /var/www/app/cache - /var/www/app/logs Data Containers Containerised logs and cache!
  11. composer install --ignore-platform-reqs • IDE AutoComplete • Cached to ~/.composer

    • Not passing keys or tokens to Docker container for satis / private repositories Composer Keep it local
