Werf (previously known as Dapp) is made to implement and support Continuous Integration and Continuous Delivery (CI/CD).

It helps DevOps engineers generate and deploy images by linking together:

• application code (with Git support),
• infrastructure code (with Ansible or shell scripts), and
• platform as a service (Kubernetes).

Werf simplifies development of build scripts, reduces commit build time and automates deployment. It is designed to make engineer's work fast end efficient.

• Building multiple images from one description.
• Sharing a common cache between builds.
• Reducing image size by detaching source data and build tools.
• Running distributed builds with common registry.
• Advanced tools to debug built images.
• Tools for cleaning both local and remote Docker registry caches.
• Deploying to Kubernetes via helm, the Kubernetes package manager.
