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.
