How to safely remove worker nodes from kubernetes cluster

Sometimes we need to remove worker nodes from Kubernetes cluster due to some reason. Here is the steps to remove the worker node from Kubernetes Cluster.

Step 1:

Get the node name which needs to remove from cluster,

# kubectl get nodes



Step 2:

Drain the node from cluster,

# kubectl drain <node-name>

If you want to ignore daemonsets and local-data in the machine, use below command,

# kubectl drain <node-name> --ignore-daemonsets --delete-local-data



After executed drain command, check all the pods are moved to another node and its running fine.

check the node status now,

# kubectl get nodes



Step 3 :

Now delete the node from cluster,

# kubectl delete node <node-name>




That's all, now the worker node is safely removed from the cluster.
