1. iso 이미지를 만들기 위한 yaml 설정

• 이미지 미러까진 똑같이하고 /root/clusterconfigs에 아래 파일 생성

agent-config.yaml

2. iso 이미지 생성

yum install -y nmstate

./openshift-install agent create image --dir /root/clusterconfigs/

3. 생성한 iso 파일로 master 부팅

• iso 파일로 부팅하고 가만히 놔두면 알아서 설치가된다.
• 확인명령(베스쳔에서)

 ./openshift-install --dir /root/clusterconfigs agent wait-for install-complete --log-level info

installation stage Writing image to disk 가 100%가 되면 master노드가 재부팅된다. 이때 cd가아니라 disk로 부팅으로 변경후 재부팅하자.

그리고 기다리면 설치가 완료된다.
