Docker Supports Open Source
Open Source is in our DNA
Docker is built for developers, by developers. We enable team collaboration, efficient packaging, and scalable distribution of open-source projects, all with a focus on trust and security.
Docker Hub Empowers Open-Source Innovation
The Home for Open Source
Docker Hub enables open-source projects to thrive, providing a free, secure, and scalable platform to distribute and collaborate on containerized applications. With more than 24 millions of developers relying on Docker Hub, open-source maintainers can effortlessly share their work, streamline contributions, and ensure software remains accessible, secure, and up to date.
Free hosting and collaboration
Docker Hub provides free public repositories for open-source projects, making it easy for the community to share, manage versions and contribute.
Security and automation
provides official images, vulnerability scanning and integration with CI/CD pipelines to keep containers secure and up to date.
Discovery and standardisation
Acts as a hub for discovery, distribution and standardisation of containerised applications, supporting cross-platform images and best practice.
14M+
container images in Docker Hub
11B+
monthly image downloads
Docker-Sponsored Open Source (DSOS) Program
Open Source Projects Proudly Supported by Docker
As part of the Docker-Sponsored Open Source (DSOS) program, Docker supports the developer community working on non-commercial open-source projects.
Open Source Developer Tools Developed by Docker
Essential Tools for Containerized Development
Docker open-source projects provide developers with essential tools to build, test, and deploy applications efficiently. These projects are widely adopted across the industry, enabling seamless workflows for software development and container orchestration.
Compose
Docker Compose is a tool for defining and running multi-container applications. It is the key to unlocking a streamlined and efficient development and deployment experience.
Docker GitHub Actions
GitHub Actions is a popular CI/CD platform for automating your build, test, and deployment pipeline. Docker provides a set of official GitHub Actions for you to use in your workflows.
Testcontainers
Testcontainers is an open source framework for unit testing that provides throwaway, lightweight instances of databases, message brokers, web browsers, or just about anything that can run in a Docker container.
Buildx
Buildx is the client that provides an extended user interface and enhanced build capabilities with BuildKit. It also provides Bake as an abstraction tool that lets you more easily manage your build configuration in a consistent way.
Essential Projects Docker Maintains
Core Components for the Container Ecosystem
Docker actively maintains key open-source projects that form the foundation of modern containerized applications. These projects ensure security, performance, and compatibility across container runtimes and orchestration platforms.
Containerd
The core container runtime which spun out of Docker to become the most used in the industry and a graduated CNCF project
Moby
An open framework to assemble specialized container systems without reinventing the wheel
