Kubernetes-Zero-to-Hero

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

1. Python3
2. AWS CLI
3. kubectl

Install dependencies

Add the new Kubernetes repository:

sudo apt-get update
sudo apt-get install -y ca-certificates curl apt-transport-https

curl -fsSL https://pkgs.k8s.io/core:/stable:/v1.28/deb/Release.key | sudo gpg --dearmor -o /etc/apt/keyrings/kubernetes-apt-keyring.gpg

echo 'deb [signed-by=/etc/apt/keyrings/kubernetes-apt-keyring.gpg] https://pkgs.k8s.io/core:/stable:/v1.28/deb/ /' | sudo tee /etc/apt/sources.list.d/kubernetes.list

sudo apt-get update
sudo apt-get install -y kubectl

Install AWS CLI (Ubuntu 24.04 compatible):

sudo snap install aws-cli --classic

export PATH="$PATH:/home/ubuntu/.local/bin/"

Install KOPS (our hero for today)

curl -LO https://github.com/kubernetes/kops/releases/download/$(curl -s https://api.github.com/repos/kubernetes/kops/releases/latest | 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

1. AmazonEC2FullAccess
2. AmazonS3FullAccess
3. IAMFullAccess
4. AmazonVPCFullAccess

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 s3api create-bucket --bucket kops-abhi-storage --region 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-abhi-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
