Jenkinsfile example using ssh and scp

gradle로 빌드 가능한 application을 ec2 instance 내 tomcat webapps directory에 복사하는 과정을 Jenkinsfile로 생성한 내용을 간단히 정리해보았다.

환경

• Git repository로 Bitbucket Server 사용
• Jenkins 2.235.1
• EC2 instance 상에 tomcat으로 Application 동작

사전 준비

사전에 credential 두개를 Jenkins 상에서 생성한다.

• jacobbaek : bitbucket에서의 credential ("username and password" type으로 credential 생성)
• ec2-user-credential : ec2 instance에 로그인할 ec2-user의 ("ssh username with private key" type으로 credential 생성)

Jenkinsfile

pipeline {
  agent any
  stages {
    stage('clone the source codes') {
      steps {
        # credential 
        git(url: 'https://bitbucket-server.co.kr/scm/test.git', branch: 'master', poll: true, credentialsId: 'jacobbaek')
      }
    }

    stage('build by gradle') {
      steps {
        sh 'ls -al && ./gradlew build'
      }
    }

    stage('check war file existence') {
      steps {
        sh '''# check
ls -al
ls -al build'''
      }
    }

    stage('deploy') {
      steps {
        sshagent (credentials: ['ec2-user-credential']) {
          sh "scp -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no -r build/libs/ROOT.war ec2-user@ec2-server-domain://tmp"
          sh "ssh -vvv -o StrictHostKeyChecking=no -T ec2-user@ec2-server-domain sudo cp -f /tmp/ROOT.war /usr/local/tomcat/webapps/"
          // sh "scp -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no -r build/libs/ROOT.war ec2-user@ec2-server-domain://usr/local/tomcat/webapps/"
          //sh "scp -o 'StrictHostKeyChecking no' -r build/libs/ROOT.war ec2-user@ec2-server-domain://usr/local/tomcat/webapps/ROOT/"
          // sh "ssh -vvv -o StrictHostKeyChecking=no -T ec2-user@ec2-server-domain"
        }

      }
    }

  }
}
