+Setup Kubernetes (K8s) Cluster on AWS Using KOPS
+
+#!/bin/bash
+#1) Create Ubuntu EC2 instance in AWS
+
+#2) install AWSCLI
+
+ sudo apt update -y
+ sudo apt install unzip wget -y
+ sudo curl https://s3.amazonaws.com/aws-cli/awscli-bundle.zip -o awscli-bundle.zip
+ sudo apt install unzip python -y
+ sudo unzip awscli-bundle.zip
+ sudo ./awscli-bundle/install -i /usr/local/aws -b /usr/local/bin/aws
+ 
+ 
+#3) Install kops software on ubuntu instance:
+
+ 	#Install wget if not installed
+ 	sudo apt install wget -y
+ 	sudo wget https://github.com/kubernetes/kops/releases/download/v1.16.1/kops-linux-amd64
+ 	sudo chmod +x kops-linux-amd64
+ 	sudo mv kops-linux-amd64 /usr/local/bin/kops
+ 
+#4) Install kubectl
+
+ sudo curl -LO https://storage.googleapis.com/kubernetes-release/release/$(curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt)/bin/linux/amd64/kubectl
+ sudo chmod +x ./kubectl
+ sudo mv ./kubectl /usr/local/bin/kubectl
+ aws s3 mb s3://nubonglegah.k8.local
+ aws s3 ls
+
+# 5) Create an IAM role from AWS Console or CLI with below Policies.
+
+	AmazonEC2FullAccess 
+	AmazonS3FullAccess
+	IAMFullAccess 
+	AmazonVPCFullAccess
+
+
+Then Attach IAM role to ubuntu server from Console Select KOPS Server --> Actions --> Instance Settings --> Attach/Replace IAM Role --> Select the role which
+You Created. --> Save.
+
+
+
+#6) create an S3 bucket Execute below commond in KOPS Server use unique bucket name if you get bucket name exists error.
+
+	aws s3 mb s3://nubonglegah.k8.local
+	aws s3 ls
+	
+    ex:
+	# S3 bucket name should be unique across AWS
+	aws s3 mb s3://simonlegah.k8s.local    s3://nubong.k8s.local
+     
+	Expose environment variable:
+
+    # Add env variables in bashrc
+    vi .bashrc
+	
+	# Give Unique Name And S3 Bucket which you created.
+	export NAME=s3://legah2045.k8.local
+	export KOPS_STATE_STORE=s3://legah2045.k8.local
+ 
+    source .bashrc
+	
+#7) Create sshkeys before creating cluster
+
+    ssh-keygen
+ 
+
+# 8)Create kubernetes cluster definitions on S3 bucket
+
+	kops create cluster --zones us-east-2c --networking weave --master-size t2.medium --master-count 1 --node-size t2.large --node-count=2 ${NAME}
+	
+	kops create cluster --zones us-east-1e,zones us-east-2c --networking weave --master-size t2.medium --master-count 2 --node-size t2.micro --node-count=2 ${NAME}
+
+	kops create secret --name ${NAME} sshpublickey admin -i ~/.ssh/id_rsa.pub
+
+# 9) Create kubernetes cluser
+
+	 kops update cluster ${NAME} --yes
+
+# 10) Validate your cluster(KOPS will take some time to create cluster ,Execute below commond after 3 or 4 mins)
+
+	   kops validate cluster
+ 
+# 11) To list nodes
+
+	  kubectl get nodes 
+  
+  
+  
+# 12) To Delete Cluster
+
+   kops delete cluster --name=${NAME} --state=${KOPS_STATE_STORE} --yes  
+

+
+
+13# IF you wan to SSH to Kubernates Master or Nodes Created by KOPS. You can SSH From KOPS_Server
+
+ssh  admin@<IPOrDNS>
+it above command  is not working
+then execute
+ssh -i ~/.ssh/id_rsa admin@<IPOrDNS>
