❗key pair를 찾을 수 없다라는 에러가 보이면 아래 명령어를 활용 (ng key-pair 없어서 생긴 에러)

ssh-keygen 
# enter 세번 (default 값 생성)

# (참고) 만들어진 key-pair를 AWS console로 옮기고 싶다면...
aws ec2 import-key-pair --public-key-material fileb://~/.ssh/id_rsa.pub  --key-name <nodegrp-key-name>

# 키 생성 후 재시도
eksctl create cluster -f create-cluster.yaml

# 생성된 클러스터 노드 그룹 확인
kubectl get node
