@pubgcorp/kubectl v1.2.1

How to Use

1. Implement IKubeConfigFactory

class KubeconfigFactory implements IKubeconfigFactory {
    public async getKubeconfigs(): Promise<{ [name: string]: IKubeconfig }> {
        // TODO: Implement method making Dictionary<name, IKubeconfig> 
    }
}

2. Create Kubectl Instance

• General Version

  const kubectl = new Kubectl(new KubeconfigFactory());

• Using tsyringe Version

  // entrypoint of application
  container.register<Kubectl>(Kubectl, { useFactory: (c) => new Kubectl(c.resolve(KubeconfigFactory)) });

3. Examples

• Get Resource

  export interface KubectlResponse {
      status: string;
      message: string;
      obj?: any;
  }

  // clusterName is key of dictionary<name, K8sCluster>
  const result: KubectlResponse = await kubectl.targetCluster(clusterName).get(namespace, kind, name);

  for custom resource

  // apiVersion means like kubernetes-client.io/v1
  const result: KubectlResponse = await kubectl.targetCluster(clusterName).get(namespace, kind, name, apiVersion);

• Apply Resource

  const K8sObjects = [{
      kind: 'Namespace',
      apiVersion: 'v1',
      metadata: {
          name: 'abcdefg',
          labels: {},
          annotations: {},
      }
  }]
  const result = await kubectl.targetCluster(clusterName).apply(k8sObjects);

• Patch Resource

  if useJsonPatch is true, use object as json patch object, otherwise get target and merge with object.

  const result = await kubectl.targetCluster(clusterName).patch(namespace, target, targetName, object, useJsonPatch);
