#ssh key 생성
sshpass -p vagrant ssh -T -o StrictHostKeyChecking=no vagrant@node01
sshpass -p vagrant ssh -T -o StrictHostKeyChecking=no vagrant@node02

 

CMD

cd "vagrant 파일 위치"
vagrant up

#vagrant 확인 명령어
vagrant ssh ansible-server
ping node1
ping node2

 

vagarnt를 통해서 ansible-server, node1, node2를 만들었으며, ansible-server에 host값을 입력하여 node들과 통신이 가능하도록 하였다.
