안녕하세요 수강생입니다. 다름이 아니라 window에 ssh 접속에 저 말고도 많은 분들이 문제를 겪었고 이를 openssh서버 설치등으로 해결한거 같습니다.그럼 섹션8에서 ssh서버 설치를 도커를 활용해서 하는데 이것과는 관계가 없는 것인가요?이번 실습은 섹션8 강의 내용과 무관하고 openssh서버 등을 설치하면 되는 건가요? 아니면 혹시 도커 ssh 서버를 활용하기 위해ansible server에 hosts파일 작성 시 :10022로 작성하고 진행하면 추후 수업에 문제가 없을까요? 

안녕하세요.

안녕하세요. 'Jenkins를 이용한 CI/CD Pipeline 구축' 강의 수강생입니다. 다름이 아니라, 본 강의에서 정말 많은 내용을 다뤄주시고 설명도 자세하게 해주셔서 따로 정리하고 싶어서요.혹시 강의 출처를 밝히고 블로그에 정리해도 될까 궁금해서 질문 남깁니다. CI/CD 에 대해 감이 안잡혀서 힘들어했는데, 본 강의 듣고 흐름을 점차 이해 중입니다! 항상 좋은 강의 감사드립니다. 😊

도원님 안녕하세요. 질문이 있어서 글 남깁니다. 강의를 보고 젠킨스에서 빌드 후 조치에 위와 같이 명령어를 입력하니 아래와 같이 오류가 발생합니다. 쉘에서 명령어(docker run -p 8080:8080 --name mytomcat cicd-project:latest)를 입력하면 빌드가 되고 웹페이지에 접속이됩니다. 하지만 젠킨스에서 빌드를 하면 ERROR: Exception when publishing, exception message [Exec exit status not zero. Status [125]]... 오류가 발생하였고 웹페이지에 접속이 되지 않았습니다. 혹시 의심가는 부분이 있는지 알려주시면 제가 다시 해보겠습니다.매번 감사드립니다.^^

도원님 안녕하세요. 강의를 듣다가 막히는 부분이 있어서 질문 드립니다. 해당 강의 7분 41초 경에 docker 이미지를 받은 후, ssh root@localhost -p 10022 위 명령어를 실행시켰는데, kex_exchange_identification: Connection closed by remote host라는 메시지가 나오면서 접속이 되지 않습니다. 답변 부탁드립니다. 감사합니다!

커뮤니티에 올라온 것을 보니 강의자료가 있었다 없었다 하는 것 같은데, 지금은 또 없네요.. 빠른 확인 부탁드립니다.

포트를 8083으로 설정하고 localhost:8083 으로 들어가도 페이지가 작동하지 않는다고 뜨네요..8080 포트를 lsof -i tcp:8080으로 조회해서 kill -9 으로 해도 자꾸 사용중이라고 뜹니다. docker run -d -p 8083:8083 -p 50000:50000 --name jenkins-server --restart=on-failure jenkins/jenkins:lts-jdk11 으로 실행하면 안되는건가요??  

- 학습 관련 질문을 남겨주세요. 상세히 작성하면 더 좋아요! - 먼저 유사한 질문이 있었는지 검색해보세요. - 서로 예의를 지키며 존중하는 문화를 만들어가요. - 잠깐! 인프런 서비스 운영 관련 문의는 1:1 문의하기를 이용해주세요. ---- name: Download Tomcat9 from tomcat.apache.org hosts: devops tasks: - name: Create a Directory /opt/tomcat9 file: path: /opt/tomcat9 state: directory mode: 0755 - name: Download Tomcat using get_url get_url: url: https://dlcdn.apache.org/tomcat/tomcat-9/v9.0.82/bin/apache-tomcat-9.0.82.tar.gz dest: /opt/tomcat9 mode: 0755 checksum: sha512:https://downloads.apache.org/tomcat/tomcat-9/v9.0.82/bin/apache-tomcat-9.0.82.tar.gz.sha512  버전이 9.0.82 가 출시되어서 기존의 75버전은 링크가 삭제되었네요. 갑자기 에러 발생해서 놀랐는데 직접 url들어가니 페이지 자체가 없어서 발생한 에러였습니다. 여러분은 헷갈리지 마세용~

안녕하세요.강의를 듣다보니 질문사항이 생겨 여쭤봅니다. 강의에서 Jenkins-server에서 빌드된 war파일을 ansible-server까지 연동하여. 실제 ansible 서버에서 docker server로 docker 명령어를 날리는 것 까지는 이해 했습니다.하지만 docker server에서 docker 명령어를 날릴 시, 해당 docker server에서는 war파일이 존재하지 않아 에러가 발생하지 않나요?해서 저는 ansible playbook에 docker 명령어 전 copy명령어를 통해 ansible -> docker로 war파일을 전송하는 task를 하나 더 추가하여 해결하였습니다. 혹 제가 놓친 부분이 있어서 이런 작업을 추가한건가요 ?(제가 개인서버를 보유중이라 개인서버 2대로 현재 강의를 따라가다 보니 환경적으로 조금 달라 제가 이해한 부분대로 강의를 따라가고 있습니다..) 답변 주시면 감사하겠습니다.
