Jenkins 와 Github 연결해서 webhook으로 배포를 시도하고 있었는데 credentialsId 와 SSH 키를 설정해도 아래와 같은 문제가 발생했다.

Verifying host key using known hosts file
You're using 'Known hosts file' strategy to verify ssh host keys, but your known_hosts file does not exist, please go to 'Manage Jenkins' -> 'Configure Global Security' -> 'Git Host Key Verification Configuration' and configure host key verification.

Finished: FAILURE여기서 중요한 부분이 아래의 로그인 것 같은데, 호스트 키를 인식하지 못하는 문제인 것 같다.

Host key verification failed.구글링을 해본 결과,

known_hosts에 등록되지 않았다고 한다.
jenkins@ea1f0b09c539:~$ git ls-remote -h (SSH github 주소) HEAD
The authenticity of host 'github.com (20.200.245.247)' can't be established.
ECDSA key fingerprint is SHA256:-/-/-.
Are you sure you want to continue connecting (yes/no/[fingerprint])? yes
Warning: Permanently added 'github.com,20.200.245.247' (ECDSA) to the list of known hosts.위와 같은 명령어를 수행하니, 새로운 HOST에 SSH를 통해 접속할 때 발생하는 경고 메시지가 나왔고, YES를 클릭했더니 이 문제는 해결되었다.
known_hosts에 github에 추가해준 것으로 해결 된 것이다.
결과적으로 github 저장소를 가져오는 건 됐지만...
이번에는 Build Gradle 에서 문제가 난다..!
installReact 문제인데, 다시 천천히 고쳐보겠다...
