Kubernetes pod yaml - Quick walkthrough

As part of this blog, we will deploy the pods_demo.yaml below in the Kubernetes cluster.

Steps to create pods in Kubernetes cluster:

1. As a pre-requisite, you need to have a docker hub account to store the image in the repository to practice along. If you don't have it, you can simply copy the yaml from my github account and run it in your Kubernetes cluster

               github path : https://github.com/Iam-7hills/kubernetes/blob/main/pods/pods_demo.yaml

     2. Login into Kubernetes cluster and execute the below command to deploy the yaml file 

                kubectl create -f pods_demo.yaml

    

    3. To verify the installation

               kubectl get pods

 4. To check the deployment log

                kubectl describe pods podsdemo

[jenkins@iam7hills kubes]$ kubectl describe pods podsdemo
