ansible sing a SSH password instead of a key is not possible because Host Key checking is enabled and sshpass does not support this

문제점

리눅스 console에서는 정상 출력되나 jenkins를 통한 ansible 명령 수행시 아래와 같은 에러가 나온다.

Using a SSH password instead of a key is not possible because Host Key checking is enabled and sshpass does not support this.  Please add this host's fingerprint to your known_hosts file to manage this host.

해결방법

/etc/ansible/ansible.cfg을 열어서 아래 값을 넣는다.(수정하고 다시 실행하면 정상 동작 됨)

host_key_checking = False

아래결과(아이피는 지움)
