I am new to kubernetes. The default cluster name is Kubernetes and I want to rename it to something more meaningful. Can anybody help?
You can change the name of a Kubernetes cluster by editing the cluster's configuration file, usually located at
--cluster-name flag in the file and replace its current value with the desired name. After making the change, you will need to restart the kube-apiserver service to apply the changes.
To rename a Kubernetes cluster, you need to update the cluster name in the cluster's API server configuration. Here are the steps to do this:
- Stop the API server:
kubectl drain <node-name> --ignore-daemonsets kubectl delete node <node-name>
- Edit the API server configuration file:
sudo nano /etc/kubernetes/manifests/kube-apiserver.yaml
- Locate the following line:
- Change the kubernetes to your desired name, for example:
Save and close the file.
Restart the API server:
kubectl create -f /etc/kubernetes/manifests/kube-apiserver.yaml
- Verify the change by running the following command:
kubectl config current-context
This should show the updated cluster name in the output.
Note: The above steps assume you are running a self-hosted Kubernetes cluster. If you are using a managed Kubernetes service, the steps may differ.
