4. Docker Project
Quick summary about the Docker project

5. • Helps developers build, ship and run applications faster
• Written in Go
• Open source!
• Under an Apache 2.0 License
• Most starred Go Project on Github
Fun fact: In the past year, 58% of pull requests submitted to the Docker Engine
were authored by people who are neither maintainers nor Docker employees,
12% by maintainers working for other companies, and 30% by Docker
employees themselves.
Introduction to the Docker Project

6. • Each subproject, or repo, has its own set of maintainers
• Want to find them? Open the MAINTAINERS file in the docker/xyz repo
• Maintainers are responsible for:
Reviewing/Approving PRs & making design decisions
Doing day-today work of running project operations
• Not all Maintainers work at Docker
• New Maintainers are added from the community by existing Maintainers
Maintainers spend their time doing whatever needs to be done, not necessarily
what is the most interesting or fun
The project structure

7. Kitematic, Compose & Machine

8. • Is the fastest and easiest way to start using Docker on your laptop
• Build and run containers through a simple, yet powerful graphical
user interface (GUI)
• Mount volumes easily via file browsing
Kitematic

9. Docker Compose
• Is a tool for defining and running multi-container Docker
applications.
• Uses a Compose file (YAML) to configure your application’s
services
• With a single command, creates and starts all the services from
your configuration.

10. Docker Machine
• Automatically sets up Docker on your cloud providers and inside
your data center
• Provisions the hosts, installs Docker Engine on them and
configures the Docker client to talk to the Docker Engines.
• Allows you to setup separate environments with a few single
commands
