apt install -y unzip python
unzip awscliv2.zip
sudo ./aws/install

8. config aws cli

aws configure

# AWS Access Key ID [None]:
# AWS Secret Access Key [None]:
# Default region name [None]: us-east-1

    --bucket k8s-example-store \
    --region us-east-1 # <- example region
    # Note: We STRONGLY recommend versioning your S3 bucket in case you ever need to revert or recover a previous state store.

OR

aws s3 mb s3://k8s-coffeeshopp-apps

# versioning buccket
aws s3api put-bucket-versioning --bucket k8s-devops-store --versioning-configuration Status=Enabled

10. add to .bashrc

# example
# kops create cluster --cloud=aws --zones=us-east-1a --name=$NAME --node-size=t2.medium --master-size=t2.medium --dns-zone=example.com --dns private

14. edit configuration

kops edit ig --name=$NAME nodes
kops edit ig --name=$NAME master-us-east-1a

15. finish and create cluster

kops update cluster --name $NAME --yes

16. check cluster

kops validate cluster --wait 10m
# or
kops validate cluster

17. ssh to master node

ssh -i ~/.ssh/id_rsa ubuntu@api.$NAME

18. delete cluster

kops delete cluster --name=$NAME --state=$KOPS_STATE_STORE --yes
