Kapitan: Configuration Management for Kubernetes, Terraform, and Infrastructure

Kapitan is an open source configuration management tool for Kubernetes, Terraform, and complex infrastructure systems. It helps teams generate, organize, reuse, and validate configuration across environments using an inventory-driven model, templates (Jsonnet, Jinja2, Kadet), and integrations with Helm, Kustomize, CUE, and external references.

Kapitan provides native secrets management (GPG, AWS KMS, GCP KMS, Azure Key Vault, HashiCorp Vault) and is designed for Platform Engineering and GitOps workflows.

Quick start

The fastest way to try Kapitan is with the Kapitan Reference repository:

git clone https://github.com/kapicorp/kapitan-reference.git kapitan-templates
cd kapitan-templates
./kapitan compile

For a minimal project from a cookiecutter template:

pip3 install cruft
cruft create https://github.com/kapicorp/kapitan-reference --checkout cookiecutter --no-input

Docker (recommended)

docker run -t --rm -v $(pwd):/src:delegated kapicorp/kapitan -h

On Linux, add -u $(id -u) to preserve file permissions.
