Creating this repo with an intent to make Kubernetes easy for begineers. This is a work-in-progress repo.

Kubernetes Installation Using KOPS on EC2
Create an EC2 instance or use your personal laptop.
Dependencies required

Install dependencies
curl -s | sudo apt-key add -
echo "deb kubernetes-xenial main" | sudo tee -a /etc/apt/sources.list.d/kubernetes.list
sudo apt-get update
sudo apt-get install -y python3-pip apt-transport-https kubectl
pip3 install awscli --upgrade
export PATH="$PATH:/home/ubuntu/.local/bin/"

Install KOPS (our hero for today)

curl -LO$(curl -s | grep tag_name | cut -d '"' -f 4)/kops-linux-amd64

chmod +x kops-linux-amd64

sudo mv kops-linux-amd64 /usr/local/bin/kops
Provide the below permissions to your IAM user. If you are using the admin user, the below permissions are available by default
Set up AWS CLI configuration on your EC2 Instance or Laptop.
Run aws configure

Kubernetes Cluster Installation
Please follow the steps carefully and read each command before executing.

Create S3 bucket for storing the KOPS objects.

aws s3mb s3://kops-abhi-storage = us-east-1

Create the cluster

kops create cluster --name=demok8scluster.k8s.local --state=s3://kops-abhi-storage --zones=us-east-1a --node-count=1 --node-size=t2.micro --master-size=t2.micro --master-volume-size=8 --node-volume-size=8
Important: Edit the configuration as there are multiple resources created which won't fall into the free tier.
kops edit cluster myfirstcluster.k8s.local
Step 12: Build the cluster

kops update cluster demok8scluster.k8s.local --yes --state=s3://kops-arun-storage

This will take a few minutes to create............

After a few mins, run the below command to verify the cluster installation.

kops validate cluster demok8scluster.k8s.local
