Docker App is a way to define, package, execute, and manage distributed applications and coupled services as a single, immutable object. Making complex multi-service applications as easy to build, share and run as single containers, Docker App is the first implementation of the open Cloud-native Application Bundle (CNAB) specification and help organizations improve collaboration across development teams and operations, drive more transparency and consistency in application development and simplify the tracking and versioning of distributed applications.
Docker Apps can be templated and provided to new developers, leveraging the same familiar Docker workflows and intuitive commands.
Simplify build tracking, branching and versioning for multi-service applications while independently iterating on code without breaking the application.
Leverage and reuse different application services while providing a clear system of record for standard deployment models across different clouds.
Governed by the Linux Foundation, CNAB is an open application packaging format specification with contributions from Docker, Microsoft, Pivotal, IBM, HashiCorp and others. Docker App is the first implementation of the CNAB specification.
Similar to Docker images, a Docker App is immutable, making it easy to track and manage. Docker App maintains consistency across deployments for easier troubleshooting, updating and rolling back.
Compliant with the Open Container Initiative (OCI) image specification, Docker Apps can be stored in standard OCI registries including Docker Hub and Docker Trusted Registry.
Docker Hub provides a fast onboarding experience for individual developers. Register for Docker Hub and access Docker Desktop Community as well as guided tutorials to get your first containerized app running in minutes.
