How to deploy pods?

Lets now take a look to create a nginx pod using kubectl.

Step 1: To deploy a docker container by creating a POD.

kubectl run myapp --image nginx

Step 2: To get the list of pods

kubectl get pods

Step 3: Run the command **kubectl describe pod <<podname>>**look under the containers section.

kubectl describe pod myapp

kubectl delete pod myapp

Step 4: Create a pod definition YAML file and use it to create a POD or use the command kubectl run myapp-pod --image=nginx.

kubectl run myapp-pod --image=nginx --dry-run=client -o yaml > myapp-pod.yaml

kubectl create -f myapp-pod.yaml

Step 5: View the Manifest and the file would like something like this or you can modify the file as below. Some not important structure is removed from the original file.

apiVersion: v1
kind: Pod
metadata:
  labels:
    run: myapp
  name: myapp-pod
spec:
  containers:
  - image: nginx
    name: myapp-container
  restartPolicy: Always
