Hi Jaejong The kuberneres/cks cluster created in Cloudstack are created via Kubeadm tool which always creates with the default name as kubernetes
You can rename the cluster as per your requirement by following this article https://medium.com/@manumv1/how-to-rename-a-kubernetes-cluster-c10db35d92aa From kubectl perspective your kubernetes cluster can be named totally differently than in kubeadm-config ConfigMap. They are configured independently. Actually in .kube/config file you can refer to your cluster by any name you want, but you need to make the change both in clusters as well as in contexts sections. Also you can reach out to the kubeadm community to cross check if they can support specifying a name during k8s cluster creation https://github.com/kubernetes/kubeadm/issues/416 Regards Kiran From: jaejong <cb...@naver.com> Date: Monday, 15 April 2024 at 5:53 AM To: users@cloudstack.apache.org <users@cloudstack.apache.org> Subject: How to kcs cluster name with supplied name? I create kcs community iso 1.28.4 on acs 4.19.0.1. I create two clusters. The cluster name is not populated to Config. In cluster kubeconfig, cluster name is kubernetes and user is kubernetes-admin. So I can not merge two into one. I remember it is possible in previous version. kubeconfig is created with the name I supplied when create kubernetes cluster such as: apiVersion: v1 clusters: - cluster: certificate-authority-data: ... server: https://x.x.x.x:6443 name: supplied-name contexts: - context: cluster: supplied-name user: supplied-name-admin name: supplied-name-admin@kubernetes kind: Config preferences: {} users: - name: supplied-name-admin user:---- So I can distingush two clusters. Is there any way I can change cluster name in kubeconfig?
