Import

Any kind of KubernetesCluster can be imported in the operator. Credentials are stored in Kubernetes secrets from which the KubernetesCluster collection access to connect to the clusters.

Once you have imported the KubernetesCluster, all the resources in the cluster that can be watched, will be read by the operator.

Requirements

• The kubeconfig file to access the cluster

Process

1. Create the Secret

Get the kubeconfig file that can be used to access the cluster, and save it as kubeconfig.yaml.

Then create the Secret with the following command:

kubectl create secret generic source --from-file=kubeconfig.yaml=kubeconfig.yaml

2. Create the KubernetesCluster

Define the KubernetesCluster object with the following YAML, and save it as cluster.yaml:

apiVersion: assets.astronetes.io/v1alpha1
kind: KubernetesCluster
metadata:
  name: cluster-1
spec:
  secretName: <secret_name>

Deploy the resource with the following command:

kubectl create -f cluster.yaml
