GitOps CLI tool

Deliver your application fast & easy.
Open Source. Written in Go.
CLI tool to construct CI/CD pipelines
  • Werf is a single CLI tool that integrates well known tools:
    git, helm and docker.
  • Werf can be embedded into any existing CI/CD system (like GitLab CI)
    to implement CI/CD pipelines using provided building blocks:
    • werf build-and-publish;
    • werf deploy;
    • werf dismiss;
    • werf cleanup.
  • Open Source, written in Go.
  • Werf is not a SAAS, we consider it a new generation
    of high-level CI/CD tools.
  • Comfortable deployment
    • Full compatibility with Helm.
    • Easy RBAC definition.
    • Applied deploy configuration in Kubernetes does not guarantee a rolled out functioning application. With werf you receive that guarantee.
    • Werf fails fast when a problem has been detected in the CI/CD job allowing faster debug of new application versions without unnecessary kubectl invocations.
    • Configurable resource errors detector and resource readiness detector using resource annotations.
    • Rich logging and error reporting.
  • Image Lifecycle Management
    • Build images with Dockerfiles or advanced image builder with incremental rebuilds based on the git history and ansible.
    • Publish images to the Docker registry using advanced image naming schemas.
    • Deploy application images into Kubernetes cluster.
    • Cleanup Docker registry from unused images based on policies.

  • Advanced tools for debugging the build process
    In the process of assembling, you can access a certain stage using introspection options.
  • Comfortable deployment to Kubernetes
    Deploy to Kubernetes using standard Kubernetes package manager with interactive tracking of the deployment process and real-time logs browsing.
