#Ansible 서버에서 id_rsa.pub 생성하기

ssh-kegen
#(엔터 세번)
vi .ssh/id_rsa.pub
#내용을 각 노드의 auth에 복사

#Ansible 서버에서 host 등록하기

#sudo vi /etc/ansible/host
#맨 아래 부분에 작성

[master]
<master EC2의 ip>
ubuntu@<master EC2의 ip>

[worker]
<worker EC2의 ip>
ubuntu<worker EC2의 ip>

#master와 worker의 host를 묶어서 사용할 때 사용
[dockerswarm:children]
master
worker

#Ansible 서버에서 EC2에 키 복사해주기

ssh-copy-id root@<EC2-master의 ip>
ssh-copy-id root@<EC2-worker의 ip>

#각 EC2에 접속해서 authorized_keys파일에 Ansible의 공유키(id_rsa.pub) 입력하기

ssh ec2-user@<EC2의 ip>로 접속

ssh-keygen

vi .ssh/authorized_keys

아래 부분에 Ansibl의 공유키 입력

#ansible 서버에서 접속 확인
