werf
A CLI tool for implementing full-cycle CI/CD to Kubernetes using Git, Dockerfile, and Helm.
What is werf?
werf is a CNCF Sandbox CLI tool designed to streamline and simplify the implementation of full-cycle CI/CD pipelines for Kubernetes applications. It integrates seamlessly into existing CI systems and leverages familiar technologies like Git, Dockerfile, and Helm to facilitate efficient and consistent software delivery.
DevOps engineers, platform engineers, and development teams building and deploying applications to Kubernetes who want a unified tool for the entire application lifecycle from build to deployment.
Developers choose werf because it provides a complete, production-ready solution that glues together common technologies like Git, Buildah, and Helm into a cohesive workflow, offering advanced features such as automatic build caching, content-based tagging, and unique container registry cleanup.
Overview
A solution for implementing efficient and consistent software delivery to Kubernetes facilitating best practices.
Use Cases
Best For
- Implementing full-cycle CI/CD pipelines for Kubernetes applications using existing CI systems.
- Teams seeking to simplify Kubernetes deployments with familiar tools like Dockerfiles and Helm charts.
- Projects requiring automated container image building, publishing, and registry cleanup.
- Organizations needing enhanced resource tracking and extra capabilities in Helm for Kubernetes deployments.
- Development teams using popular frameworks like Node.js, Spring Boot, Django, Rails, or Laravel who want ready-to-use Kubernetes delivery examples.
- Production environments that require a reliable, battle-tested tool proven since 2017 for diverse application deployments.
Not Ideal For
- Teams not deploying to Kubernetes or using alternative container orchestration platforms like Nomad or Docker Swarm.
- Organizations with fully integrated CI/CD suites like GitLab CI/CD Auto DevOps, where werf might add redundant tooling.
- Projects with minimal CI/CD needs that could be handled by simpler, single-purpose tools like skaffold for local development or flux for GitOps deployments only.
Pros & Cons
Pros
Handles everything from building images with Dockerfile to deploying with Helm and cleaning up the registry, as emphasized in the README's key features.
Leverages Dockerfile and Helm charts, reducing the learning curve for teams already using these standard technologies.
Includes automatic build caching and content-based tagging, which improve efficiency and consistency in CI/CD pipelines.
Used in production since 2017 and trusted by thousands of projects, ensuring stability for diverse applications.
Cons
Requires integration with CI systems and configuration of dependencies like Buildah and Helm, which can be time-consuming and error-prone.
Relies heavily on Git, Dockerfile, Helm, and Kubernetes, so issues or updates in these tools can directly impact werf's functionality.
As a CNCF Sandbox project, it has fewer community plugins and integrations compared to more established tools like Jenkins or Argo CD.
