인프런 커뮤니티 질문&답변

안녕하세요 jenkins를 이용해서 배포를 하려고 강의를 들으면서 진행중에 있습니다.

잘 따라하던 중 강의와는 다른 오류가 떠서 해결하려 했으나 여전히 같은 오류가 뜹니다

강의에서는 pipeline script를
pipeline {

agent any

tools {

maven "M3" // Jenkins에서 설정한 Maven의 이름

}

stages {

stage('Checkout') {

steps {

git url: 'https://github.com/lleellee0/deploy-test', branch: 'main'

}

}

stage('Build') {

steps {

script {

sh 'mvn clean package'

}

}

}

stage('Deploy') {

steps {

script {

// Maven 빌드로 생성된 jar 파일의 위치

def jarFile = 'target/shortenurlservice-0.0.1-SNAPSHOT.jar'

// 원격 서버의 IP 주소 및 배포 경로

def serverIp = 'xxx.xxx.xxx.xxx'

def deployPath = '/root'

def runAppCommand = "java -jar $deployPath/shortenurlservice-0.0.1-SNAPSHOT.jar"

// 서버에 파일을 SCP로 전송

sh "scp -o StrictHostKeyChecking=no $jarFile root@$serverIp:$deployPath/"

// 원격 서버에서 애플리케이션 실행

sshagent(['deploy_ssh_key']) { // 'server-ssh-credentials'는 Jenkins에서 설정한 credentials ID

sh "ssh -o StrictHostKeyChecking=no root@$serverIp '$runAppCommand'"

}

}

}

}

}

post {

success {

echo 'Deployment was successful.'

}

failure {

echo 'Deployment failed.'

}

}

}
이렇게 설정하였으나 저는 제가 만든 프로젝트와 깃허브 레포지토리가 있어 git url부분을 제 레포지토리 주소로 변경했더니 뜬 오류입니다.

인증 방식에 문제가 있는것 같아 ssh로 깃허브 ssh와 jenkins ssh에

putty로 접속한 .ssh 즉 root@jenkins instance에서 publickey와 privatekey를 발급해 설정했음에도 jenkins에서 지금 빌드 버튼을 누르면 같은 오류가 발생하면서 빌드가 되지 않습니다.

구글 서치를 통해 이것저것 시도도 해보고 설정도 다시 해봤으나
github의 webhook에서 보면 설정이 잘 된거같은데

왜 자꾸 인증 오류가 뜨면서 ERROR: Error fetching remote repo 'origin' 이 오류가 뜨는건지 모르겠습니다.
