Overview

Highlights

Complete application lifecycle management from build to cleanup
Automatic build caching and content‑based image tagging
Seamless integration with Git, Helm, Buildah, and any CI system
Production‑grade reliability with registry cleanup capabilities

Pros

  • Leverages existing Dockerfile and Helm workflows
  • Reduces build times through intelligent caching
  • Works with a wide range of CI/CD platforms
  • Mature, production‑tested since 2017

Considerations

  • CLI‑only interface may require scripting for complex UI needs
  • Steeper learning curve for teams new to Kubernetes
  • Requires Buildah or Docker for image builds
  • Documentation depth can be overwhelming for beginners

Fit guide

Great for

  • Teams delivering containerized applications to Kubernetes
  • Organizations needing reproducible, cached builds across environments
  • DevOps pipelines that already use Git, Helm, and CI systems
  • Projects that require automated container registry cleanup

Not ideal when

  • Simple scripts or projects that do not target Kubernetes
  • Teams preferring graphical CI/CD tools over CLI
  • Environments lacking Docker or Buildah support
  • Non‑container workloads such as pure VM deployments

How teams use it

Microservice deployment with automated caching

Accelerated build times and consistent releases for microservice architectures

Multi‑environment CI pipeline

Unified Helm chart deployment across dev, staging, and production with identical configurations

Release artifact distribution

Versioned container images and Helm charts published to registries for downstream consumption

Registry cleanup after rollbacks

Automatic removal of orphaned images, freeing storage and preventing drift

Do I need Docker to use werf?

No, werf can build images using either Docker or Buildah, depending on your environment.

Is werf production‑ready?

Yes, it has been used in production since 2017 across thousands of projects.

How does werf's caching work?

It creates content‑based hashes of build inputs, reusing layers when inputs haven't changed, which speeds up subsequent builds.

Where can I get support for werf?

Support is available via GitHub Discussions, Stack Overflow (tagged werf), CNCF Slack #werf channel, and Telegram chats.
