docker, jenkins 실행 목록

 

📚 1. plug in 추가 및 설정

✔️ SSH Agent 추가 (plugins에서 추가해주면 된다.)

 

✔️ Credentials에 ec2 추가

 

• Kind : SSH Username with private key를 선택
• ID : 하고 싶은 ID
• Username : ubuntu
• Private Key, Enter directly에서 add버튼 클릭 후, server 인스턴스의 pem 파일 내용을 넣어준다. (BEGIN ~ END)

• -o StrictHostKeyChecking=no : ssh접속 시 host의 key를 확인하지 않는다.

 

 

📚 2. 사용자가 push 할 때마다 사이트 업데이트 및 배포

✔️ push 할 때, ec2 가상서버가 실행되고 있다면 종료시키기

새로운 가상 서버를 open 하기 위해 이전 가상서버를 종료시킨다.

                }

 

✔ image를 pull 받고, port 8080에 9999번 포트를 뛰운다.

                sshagent(credentials: ['ECGumD208']) {
                    sh 'ssh -o StrictHostKeyChecking=no ubuntu@52.79.219.150 "docker pull lkc263/d208backend:1.0"'
