WERF Automates Kubernetes-based GitOps from the Command Line

A new project from infrastructure service provider Flant, called Werf, promises an easy way to set up GitOps-styled deployment pipelines, where code changes in a git repository trigger the appropriate containers to be rebuilt and pushed into a Kubernetes deployment — all automatically. It synchronizes the state of the registry with the state of the git, and the state of Kubernetes to the state in git,” explained Flant Chief Technology Officer Dmitry Stolyarov, in a recent webinar hosted by the Cloud Native Computing Foundation. GitOps is a term popularized by Kubernetes platform provider Weaveworks, with the idea to “make git the center of control,” of cloud native operations.

Behind the scenes, Werf builds images from code in your repository and submits a Helm manifest to Kubernetes to run the resulting containers.

If it doesn’t match, it changes the state in Kubernetes to that which is specified in git,” Stolyarov said, explaining this convergence process.
