werf

Overview of werf (CLI tool gluing Git, Docker, Helm, and Kubernetes)

werf is an Open Source CLI tool written in Go, designed to simplify and speed up the delivery of applications. To use it, you need to describe the configuration of your application (in other words, how to build and deploy it to Kubernetes) and store it in a Git repo — the latter acts as a single source of truth. In short, that's what we call GitOps today.

• werf builds Docker images using Dockerfiles or an alternative fast built-in builder based on the custom syntax. It also deletes unused images from the Docker registry.
• werf deploys your application to Kubernetes using a chart in the Helm-compatible format with handy customizations and improved rollout tracking mechanism, error detection, and log output.

Features of werf

• Full application lifecycle management: build and publish images, deploy an application to Kubernetes, and remove unused images based on policies.
• The description of all rules for building and deploying an application (that may have any number of components) is stored in a single Git repository along with the source code (Single Source Of Truth).
• Build images using Dockerfiles.
• Alternatively, werf provides a custom builder tool with support for custom syntax, Ansible, and incremental rebuilds based on Git history.
• werf supports Helm compatible charts and complex fault-tolerant deployment processes with logging, tracking, early error detection, and annotations to customize the tracking logic of specific resources.
• werf is a CLI tool written in Go. It can be embedded into any existing CI/CD system to implement CI/CD for your application.
• Cross-platform development: Linux-based containers can be run on Linux, macOS, and Windows.
