What is your development environment? Development Environment # users MAMP / WAMP / Locally installed LAMP/LEMP Stack 10 Vagrant / VMWare / Parallels / VirtualBox — Virtual Machines 6 Remote server 4 Docker / Containers 3 Other 0 3

What is Docker? • Automates the deployment of applications in software containers • Operating system abstraction layer • Open Source Project (May 2013) 4

What is a Docker software container • An isolated user-space instance — that contains a complete application with all dependencies and components needed to run properly • Shares the underlying O/S kernel • Looks and feels like a real server 5 5

What does that look like? Container Container Container Application Application Application Binaries / Libraries Binaries / Libraries Binaries / Libraries Docker Engine Host Operating System Infrastructure 6

As a Developer, how does this benefit me? 8

Benefits of Containerization • Development environment consists of components • Components can be swapped as needed for different clients / applications • If production environment is containerized, deployment is as simple as dropping a completed application in a fully tested container on the production server 9

How can I get started using Docker for development • Install the Docker Engine (Linux), Docker for Windows, or Docker for Mac • Install Docker Compose (Linux) • Create a docker-compose.yml file with your stack configuration • Execute docker-compose up -d 12

Projects to jumpstart your development efforts • Docker For Drupal (docker4drupal.org) • Docker based development environment (drupal.org), https://www.drupal.org/node/2736447 • https://github.com/peperoni60/drupal-docker • Tons more on Github, pick your flavor • Docker Hub: https://hub.docker.com • Docker Sync (for OS X) (http://docker-sync.io/) 13
