dotCloud founder and CTO Solomon Hykes recently stopped by Twitter HQ to show us Docker, an open source project designed to easily create lightweight, portable, self-sufficient containers from any application.
Common use cases for Docker include:
- Automating the packaging and deployment of applications
- Creation of lightweight, private PAAS environments
- Automated testing and continuous integration/deployment
- Deploying and scaling web apps, databases and backend services
Docker is the world’s leading software container platform. Developers use Docker to eliminate “works on my machine” problems when collaborating on code with co-workers. Operators use Docker to run and manage apps side-by-side in isolated containers to get better compute density. Enterprises use Docker to build agile software delivery pipelines to ship new features faster, more securely and with confidence for both Linux and Windows Server apps.
Docker automates the repetitive tasks of setting up and configuring development environments so that developers can focus on what matters: building great software.
Developers using Docker don’t have to install and configure complex databases nor worry about switching between incompatible language toolchain versions. When an app is dockerized, that complexity is pushed into containers that are easily built, shared and run. Onboarding a co-worker to a new codebase no longer means hours spent installing software and explaining setup procedures. Code that ships with Dockerfiles is simpler to work on: Dependencies are pulled as neatly packaged Docker images and anyone with Docker and an editor installed can build and debug the app in minutes.
