Awesome Docker [
][sindresorhus] 
A curated list of projects for Docker.
If you would like to contribute, please read CONTRIBUTING.md first.
If this list is not complete, you can contribute to make it so.
If you see a link here that is not (any longer) a good fit, you can fix it by submitting a [pull request][editreadme] to improve this file. Thank you!
The project has to be for Docker, not just using Docker.
Rule of thumb: if removing the Docker integration wouldn't kill the project's value proposition, it doesn't belong in the this list.
The creators and maintainers of this list do not receive any form of payment to accept a change made by any contributor.
This page is not an official Docker product in any way.
It is a list of links to projects and is maintained by volunteers.
Everybody is welcome to contribute.
The goal of this repo is to index open-source projects, not to advertise for profit.
Docker is an open platform for developers and sysadmins to build, ship, and run distributed applications. Consisting of Docker Engine, a portable, lightweight runtime and packaging tool, and Docker Hub, a cloud service for sharing applications and automating workflows, Docker enables apps to be quickly assembled from components and eliminates the friction between development, QA, and production environments. As a result, IT can ship faster and run the same app, unchanged, on laptops, data center VMs, and any cloud.
