Creating K8s Cluster with KOPS

Kops commands to setup k8s cluster:-

Creating S3 Bucket for Kubernetes Cluster

aws s3 mb s3:// <bucket name>

kops create cluster --name=saiteja.irrinki.xyz --state=s3://<s3 bucket> --zones=ap-south-1a,ap-south-1b --node-count=2 --node-size=t3.medium --master-size=t3.medium --dns-zone=saiteja.irrinki.xyz --node-volume-size=8 --master-volume-size=8

It will create a configuration of kops

kops update cluster --name=saiteja.irrinki.xyz --state=s3://<s3 bucket> --yes --admin

The S3 bucket will be filled with kops data. It takes 10 minutes for the cluster to be created

kops validate cluster --name=saiteja.irrinki.xyz --state=s3://<s3 bucket>

It shows ur cluster is ready

To Delete Cluster

kops delete cluster --name=saiteja.irrinki.xyz --state=s3://<s3 bucket> --yes
