ssh: 엄격한 호스트 키 확인을 비활성화했는데도 경고가 발생함

작업 을 실행 중이지만 ansible이것이 더 큰 문제입니다 ssh.

rsync내 컴퓨터 localhost에서 다음과 같이 명령을 실행합니다 .vagrant

command: "rsync -zaP  -e 'ssh -p {{ ansible_port }} -o StrictHostKeyChecking=no' {{ temp_build_directory }}/artifacts.tar.gz {{ rsync_remote_user }}@{{ ansible_host }}:/tmp"

호스트 키 확인을 명시적으로 비활성화했지만 어느 시점에서 다음 오류가 발생했습니다.
