What is Docker?

Accelerate how you build, share, and run applications

Docker helps developers build, share, run, and verify applications anywhere — without tedious environment configuration or management.

Build

Spin up new environments quickly

Accelerate your development by building Docker images locally or in the cloud with Docker Build Cloud. Create multiple containers using Docker Compose without the hassle of local build constraints.

Integrate with your existing tools

Docker seamlessly integrates with your development tools, such as VS Code, CircleCI, and GitHub. Meanwhile, Docker Build Cloud fast-tracks build times, resulting in an enhanced workflow without disruption.

Containerize applications for consistency

Ensure consistent application performance across any environment, whether it’s on-premises Kubernetes or cloud platforms like AWS ECS, Azure ACI, and Google GKE.

Share

Discover and manage container images with Docker Hub

Explore Docker Hub, the world’s largest registry, where you can discover, distribute, store, and serve cloud-native components, including container images. Access a vast repository of trusted content from verified publishers and Docker Official Images.

Collaborate with your team seamlessly

Easily pull and publish images from Docker Hub to streamline sharing within your team, organization, or the broader community. Docker Hub simplifies the management and distribution of container applications.

Ensure security and trust with Docker Hub

Secure your workspaces with robust image access management, registry access controls, and private repositories. Docker Hub offers a secure and trusted marketplace for your container images, ensuring best practices and peace of mind.

Run

Develop secure, modern applications with Docker Desktop

Docker Desktop simplifies and accelerates the development of secure, containerized applications. Gain speed through streamlined containerized development and ensure secure workflows with robust security measures that protect your code throughout the development lifecycle.

Flexible and integrated development environment

Docker Desktop provides a local environment for efficient building and testing of containerized applications. It supports a wide range of programming languages and integrates seamlessly with various developer tools, including Docker Hub for pre-built components, Docker Scout for security scanning, and third-party tools.

Streamline your development workflow

Effortlessly manage your applications with Docker Desktop’s pre-configured templates and easy integration with image registries and CI/CD pipelines. This comprehensive platform supports both individual developers and organizations, offering a secure and flexible environment for the entire application lifecycle.

Verify

Enhance security with Docker Scout

Docker Scout is a secure software supply chain solution designed to provide actionable insights for container images. It helps teams evaluate security and compliance policies, ensuring a robust security posture.

Increase transparency and visibility

Gain insights and context into your components, libraries, tools, and processes with Docker Scout. This increased transparency helps you understand and manage the software supply chain effectively.

Proactively address security concerns

Docker Scout detects and highlights security issues, offering suggestions for remediation based on policy violations and state changes. Ensure your application security by addressing concerns before they impact production.

Test

Test dependencies as code

Eliminate the need for mocks and complex environment configurations by defining your test dependencies as code. Simply run your tests, and Docker containers will be created and deleted as needed.

Unit tests with real dependencies

Utilize Testcontainers to provide lightweight, throwaway instances of databases, message brokers, web browsers, and more. Test anything that can be containerized for accurate, reliable testing.

Integrate and automate with ease

Efficiently run data access layer integration tests, UI/acceptance tests, and application integration tests using containerized instances. Enjoy a clean, consistent testing environment with minimal setup.
