c4k-common provides the foundation for all our c4k modules.

It is now possible to generate a working prometheus monitoring file in yaml format. Your config.edn and your auth.edn should at least contain the following fields:

config.edn - minimal example

{:k3s-cluster-name "your-cluster-name"
 :k3s-cluster-stage :prod
 :grafana-cloud-url "your-url"}

auth.edn - minimal example

{:grafana-cloud-user "user"
 :grafana-cloud-password "password"}

call (with jarwrapper installed):

c4k-common-standalone.jar config.edn auth.edn > monitoring.yaml


There are many comparable solutions for creating c4k deployments like helm or kustomize. Why do we need another one?

  • We like the simplicity of kustomize. Yaml in, yaml out, the ability to lint the result and the option to split large yaml files into objects. But a simple overwriting per environment may not be enough ...
  • We like helm packages. A package encapsulates the setup for an application. On the one hand, but on the other hand we don't like the idea of having to program and debug in a template language. We can program much better in real programming languages.

Our convention 4 kubernetes c4k-* tools combine the advantages of both approaches:

  • Packages for one application
  • Programming in clojure
  • yaml / edn as input and output, no more magic
  • good validation, integration as api, cli or in the browser


c4k-common provides the basic functionality for our c4k-modules.
