CLM

CLM (CRD Lifecycle Management) is a tool to manage CRDs lifecycle in Kubernetes. CLM can contribute to:

  1. Install CRD (yaml file and controller);
  2. Probe status of CRD components;
  3. Recover abnormal CRD components;
  4. Upgrade and downgrade CRD;
  5. Dependency processing of CRD;

And it can be a special workload of Kubernetes.

Architecture

CLM contains three components: architecture

  • Source: Source of CRD release, contains the actually actions to handle CRD release.

    • helm source: Using helm-sdk to handle lifecycle actions
    • native source: Using cli-runtime
    • k8s service source: Using http/https
      CLM combine the helm and kubectl to manage the CRD lifecycle.
  • CRDRelease: A release of CRD.

  • Module: The components of a CRDRelease. The smallest entity CLM handle.

module-source

  • cd config/sample/; kubectl apply -f source Install sources of CLM.

  • kubectl apply -f crdrelease/native-example.yaml Install the example crd release of native source. crd nginx

    • native.module contains two parts in native source, a remote urls CRD file resource, and a local deployment yaml.
  • kubectl apply -f crdrelease/helm-example.yaml Install the example crd release of helm source. helm

    • nginx.module download a nginx helm package and install it.
  • Check the crd releases installed. crdreleases
