Deploying a Pod to a Node with a Label in Kubernetes

Get All Node Labels

Run a command to get all labels for all cluster nodes

kubectl get no --show-labels

We can also run this to show nodes by label

kubectl get no -l disk=ssd

Create and Apply the Pod YAML

Create a file named pod.yaml and ensure that it has specified the node with the label disk=ssd

pod.yaml

apiVersion: v1
kind: Pod
metadata:
    name: new-pod
spec:
   containers:
    - name: nginx
      image: nginx 
   nodeSelector:
      disk: ssd    

Apply the YAML to your Kubernetes cluster

kubectl create -f pod.yaml
