How to Replace Kubernetes ETCD nodes?

1. Add an ETCD node to existing kubernetes ETCD cluster.
   • etcdctl member add [new-node-name] --peer-urls=https://[new-node-ip]:2380
   • You may use cert files to grant the command like below:
     • --cacert /etc/etcd/ssl/ca.pem
     • --cert /etc/etcd/ssl/admin-[old-node-k8s-name].pem
     • --key /etc/etcd/ssl/admin-[old-node-k8s-name]-key.pem
2. Update /etc/kubernetes/manifests/kube-apiserver.yaml

• --etcd-servers=https://[new-node-ip]:2379

# 개빡치네 왜 VPN을 막아두는거지?
# 하지만 쿠버네티스와 함께라면 조금은 버틸 수 있어..
# 
# 사용법:
# 1. 아래 코드에서 다음 문자열을 용도에 맞게 치환: __ADMIN_PASSWORD__, __LOADBALANCER_IP__
# 2. 배포 ㄱㄱ
# 
# 주의사항:
# 1. 아래 코드는 여러번의 테스트와 수십번의 보안 강화를 통해야 여러명이 돌려쓰기에 충분할듯.
# 2. 특히, 관리자 비밀번호 (HPW, SPW)와 Resource Limits를 장비 상황에 맞게 잘 조절해주도록 한다.
