Install a Kubernetes cluster on AWS with kops

Install prerequisites:

sudo apt install python3-pip

Install AWS CLI:

sudo pip install awscli

In IAM add a user kops with programmatic access. Note down your AWS keys.
Add your AWS keys to AWS CLI tool:

aws configure

Download and install binaries:

wget https://github.com/kubernetes/kops/releases/download/v1.21.0/kops-linux-amd64
sudo mv kops-linux-amd64 /usr/local/bin/kops
sudo chmod +x /usr/local/bin/kops
curl -LO "https://dl.k8s.io/release/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/linux/amd64/kubectl"
sudo mv kubectl /usr/local/bin/kubectl
sudo chmod +x /usr/local/bin/kubectl

Generate an SSH key which will be used to connect to the kops cluster:

ssh-keygen -f .ssh/id_rsa

Create a S3 bucket in your chosen region for kops state. I named it s3-kops-12345. Use this page to determine which region is faster: cloudping.info - measure latency from your browser to each AWS region
Add hosted zone - I used kops.qwerty.md, which is my domain. Make sure that it resolves.
Create cluster - I used the following commands:

kops create cluster --name=kops.qwerty.md --state=s3://s3-kops-12345 --zones=eu-west-2a --node-count=2 --node-size=t3.micro --master-size=t3.micro --dns-zone=kops.qwerty.md
kops update cluster --name kops.qwerty.md --yes --admin --state=s3://s3-kops-12345

Validate cluster - it will test if cluster DNS works well and if it is accesible:

kops validate cluster --wait 10m

Test cluster functionality:

kubectl create deployment hello-minikube --image=k8s.gcr.io/echoserver:1.4
kubectl expose deployment hello-minikube --type=NodePort --port=8080

Get the port for new created service:

kubectl get svc

My output was:

NAME             TYPE        CLUSTER-IP      EXTERNAL-IP   PORT(S)          AGE
hello-minikube   NodePort    100.67.254.62   <none>        8080:32259/TCP   9s
kubernetes       ClusterIP   100.64.0.1      <none>        443/TCP          7m46s

Edit Security Group for workers and add inbound port 32259 for your IP and connect to it:
http://worker_ip:32259/
you should see an echo server page if everything works well.
To delete cluster use the following command:

kops delete cluster --name kops.qwerty.md --yes --state=s3://s3-kops-12345
