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:

• 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.

See docs for more information.

• kubectl apply -f clm-server.yaml Install CLM deployment to K8s cluster.

• 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.

  • 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.

  • nginx.module download a nginx helm package and install it.

• Check the crd releases installed.
