nodegroup 생성

eksctl create nodegroup --cluster=eksnest \
                       --region=ap-northeast-2 \
                       --name=eksnest-ng-private \
                       --node-type=t3.medium \
                       --nodes=2 \
                       --nodes-min=2 \
                       --nodes-max=4 \
                       --node-volume-size=20 \
                       --ssh-access \
                       --ssh-public-key=eksnest \

                       --alb-ingress-access \
                       --node-private-networking

nodegroup을 생성할 때 private subnet의 routing table에 rds 접속용으로 기재해놓을 것 삭제해야 합니다.
