안녕하세요. 강의 진행 중 에러가 발생하여 질문드립니다. 아래와 같은 에러가 계속 발생하는데 원인을 알 수 있을까요? OS는 맥이며, 젠킨스는 도커로 인스톨하였고, 톰캣은 brew 로 9버전을 인스톨하였습니다. [My-Third-Project] $ /var/jenkins_home/tools/hudson.model.JDK/bin/java -cp /var/jenkins_home/plugins/maven-plugin/WEB-INF/lib/maven35-agent-1.13.jar:/var/jenkins_home/tools/hudson.tasks.Maven_MavenInstallation/Maven3.8.5/boot/plexus-classworlds-2.6.0.jar:/var/jenkins_home/tools/hudson.tasks.Maven_MavenInstallation/Maven3.8.5/conf/logging jenkins.maven3.agent.Maven35Main /var/jenkins_home/tools/hudson.tasks.Maven_MavenInstallation/Maven3.8.5 /var/jenkins_home/war/WEB-INF/lib/remoting-3046.v38db_38a_b_7a_86.jar /var/jenkins_home/plugins/maven-plugin/WEB-INF/lib/maven35-interceptor-1.13.jar /var/jenkins_home/plugins/maven-plugin/WEB-INF/lib/maven3-interceptor-commons-1.13.jar 35605 Exception in thread "main" java.lang.UnsupportedClassVersionError: hudson/remoting/Launcher has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 53.0 at java.base/java.lang.ClassLoader.defineClass1(Native Method) at java.base/java.lang.ClassLoader.defineClass(ClassLoader.java:1007) at java.base/java.security.SecureClassLoader.defineClass(SecureClassLoader.java:174) at java.base/java.net.URLClassLoader.defineClass(URLClassLoader.java:545) at java.base/java.net.URLClassLoader.access$100(URLClassLoader.java:83) at java.base/java.net.URLClassLoader$1.run(URLClassLoader.java:453) at java.base/java.net.URLClassLoader$1.run(URLClassLoader.java:447) at java.base/java.security.AccessController.doPrivileged(Native Method) at java.base/java.net.URLClassLoader.findClass(URLClassLoader.java:446) at org.codehaus.plexus.classworlds.realm.ClassRealm.loadClassFromSelf(ClassRealm.java:425) at org.codehaus.plexus.classworlds.strategy.SelfFirstStrategy.loadClass(SelfFirstStrategy.java:42) at org.codehaus.plexus.classworlds.realm.ClassRealm.unsynchronizedLoadClass(ClassRealm.java:271) at org.codehaus.plexus.classworlds.realm.ClassRealm.loadClass(ClassRealm.java:247) at org.codehaus.plexus.classworlds.realm.ClassRealm.loadClass(ClassRealm.java:239) at jenkins.maven3.agent.Maven35Main.main(Maven35Main.java:135) at jenkins.maven3.agent.Maven35Main.main(Maven35Main.java:65) ERROR: ================================================================================ ERROR: Invalid project setup: Connection reset ERROR: [JENKINS-18403][JENKINS-28294] JDK '' not supported to run Maven projects.

안녕하세요?ssh 서버 실행 시 Conflict, The container name "/docker-server" is already in use by container "4a08bbeafb65" 라고 에러가 나오네요.명령어는 아래와 같이 입력했고docker run --privileged --name docker-server -itd -p 10022:22 -p 8081:8080 -e container=docker -v /sys/fs/cgorup:/sys/fs/cgroup edowon0623/docker:latest /usr/sbin/initdocker ps 라고 입력 시 아무것도 안나오는데docker ps -a 입력하면 위의 4a08bbeafb65 가 Created 상태입니다. 인터넷 찾아보니 삭제하고 해보라고 해서 해 봐도 안되네요.윈도우 10 사용자입니다.위 그림은 실행 상황입니다. 두 번째 그림은 docker desktop 에서 실행하려고 할 때도 같은 메시지가 나옵니다. 

안녕하세요? Kubernetes Master Server가 강제 재부팅 된 뒤 문제가 발생하여 문의 드립니다.위와 같이 Kubectl 명령어가 현재 먹지 않는 상태이고,검색을 해 보니 아래와 같이 해보래서 해 보았으나, 해결되지 않고 있습니다. Service에 대해 상태를 확인을 해보면 위와 같이 실패로 나오고, 재부팅, Service 재시작 등을 해보아도 해결이 되지 않고 있습니다.journalctl -xeu kubelet 명령어로 확인하면위와 같이 나오고 있습니다!

 안녕하세요~Ansible playbook으로 Kubernetes Script 실행하기 위해서ansible 서버에서 ssh-copy-id를 통해 쿠버네티스 로컬서버로 접속하고자 하는데이 명령어가 정상적으로 실행이 되지 않고 있습니다.윈도우 사용자이고, 마이크로 계정으로 자동 연동된 로그인 사용하고 있습니다.아래의 이미지와 같이 에러메세지를 확인할 수가 없어서 원인이 뭔지 잘 모르겠네요 ^^;이 작업이 정상적으로 되지 않아 다음 수업진행이 어렵습니다.확인 부탁드릴께요감사합니다.

안녕하세요?https://github.com/joneconsulting/k8s/blob/master/install/kubernetes_install.md이거 보고 CentOS에 가상 머신 3개(CentOS 7)으로 올린 뒤 진행하던 중 문제가 발생하여 질문드립니다.데쉬보드를 VM Host Server에서 Firefox로 접근을 해보고 싶은데,위와 같이 접근을 할 수 가 없는 상태 입니다.하지만 Local에서 curl 명령어를 통해 API 테스트를 하면 아래와 같이 정상 처리 되는 것을 볼 수 있습니다.각 VM Server는 CLI Mode만 이용하고 싶어서 GUI가 아닌데, HOST Server 혹은 외부에서 접속을 하려면 어떻게 해야 하나요??그리고, 마지막 TEST부분에서 Port Fowarding된 Port 번호를 어떻게 확인할 수 있나요?

안녕하세요! 질문이 묻힌 것 같아 다시 작성하는 점 죄송합니다ㅠㅠㅠ 강사님의 답변을 보고 다시 docker-compose.yml파일과 .travis.yml파일을 살펴보았습니다. 8,9강에서 Docker-full-stack-app에서는 강사님 말씀처럼 도커허브의 Dockerfile을 이용해 만든 이미지를 사용하지만 6,7강에서는 Dockerfile.dev만 사용하고 Dockerfile을 사용하는 부분은 못찾겠더라구요ㅠㅠㅠ 조금은 지엽적인 질문일 수 있겠지만 너무 궁금합니다ㅠㅠ생소한 개념이 여러개 나와서 어렵지만 강사님 강의 여러번 돌려보면서 이해해보려 노력하고 있습니다! 오늘도 감사합니다!version: "3" services: react: build: context: . dockerfile: Dockerfile.dev ports: - "3000:3000" volumes: - /usr/src/app/node_modules - ./:/usr/src/app stdin_open: true tests: build: context: . dockerfile: Dockerfile.dev volumes: - /usr/src/app/node_modules - ./:/usr/src/app command: ["npm", "run", "test"]sudo: required language: generic services: - docker before_install: - echo "start creating an image with dockerfile" - docker build -t smileajw1004/docker-react-app -f Dockerfile.dev . script: - docker run -e CI=true smileajw1004/docker-react-app npm run test -- --coverage deploy: edge: true provider: elasticbeanstalk region: ap-northeast-2 app: docker-react-app env: DockerReactApp-env bucket_name: elasticbeanstalk-ap-northeast-2-972153559337 bucket_path: docker-react-app on: branch: master access_key_id: $AWS_ACCESS_KEY secret_access_key: $AWS_SECRET_ACCESS_KEY

안녕하세요.ssh-server 실행할 때 옵션추가된 명령어로 실행하도록 문의 답변 주셨는데요, 추가된 옵션에 대해 설명을 해주실수 있을까요?docker run --privileged --name docker-server -itd -p 10022:22 -p 8081:8080 -e container=docker -v /sys/fs/cgroup:/sys/fs/cgroup:rw --cgroupns=host edowon0623/docker-server:m1 /usr/sbin/init(볼륨에 :rw가 추가되었고, --cgroupns=host 이 추가된 것으로 보입니다)[질문]/sys/fs/cgroup 를 volume으로 설정하는 이유-v /sys/fs/cgroup:/sys/fs/cgroup:rw --cgroupns = host 를 추가해야하는 이유(이하 문서 내용 발췌)--cgroupns (API 1.41+) cgroup namespace to use (host|private) - 'host': Run the container in the Docker host's cgroup namespace - 'private': Run the container in its own private cgroup namespace - '': Use the cgroup namespace as configured by the default-cgroupns-mode option on the daemon (default)감사합니다.

React App 을 AWS EB 에 배포하는 과정에서 502 Error 가 발생합니다.아마 강의에서 말씀하신 것 처럼 Linux 버전 차이 말고는 다른점이 없기 때문에 Linux2 로 EB 를 설정해서 발생하는 Error 인 것 같습니다.하지만 현재 AWS EB 에서 제공하는 Docker platform 중에 강의에서 선택하신 Linux( version 1 ) 이존재하지 않는데 이 경우 어떻게 하면 문제를 해결할 수 있을까요?

안녕하세요.강의에 사용하시는 PPT 자료 받을 수 있을지 문의 드립니다.감사합니다.

강의에서처럼 Multi-container Docker를 사용하려고 하는데 이제 지원하지 않는거 같아요...그러면 그냥 Docker running on 64-bit Amazon Linux 2로 하는게 맞는 건가요??

22-07-25 기준 package.json 의 scripts 에서 start 를 위와 같이 변경하면 작동합니다.  

docker rm `docker ps -a -q` 라고 cmd에 치면은   unknown shorthand flag: 'a' in -aSee 'docker rm --help' 나오는데요.    docker rm  $(docker ps -a -q) 도 해보았고 .. 흠  혹시 해결방법이 있을까요?

안녕하세요 강사님 강의를 따라 하는 중인데요   저희가 지정한 Work directory에서 ls 명령어를 주면 저는 Dockerfile이 보이지 않습니다 ㅠㅠ   이유가 뭘까요?

이제 travis 무료 플랜이 vat id 기재를 필수로 정해서 회사 소속 없는 개인은 불가능 한거 같습니다  혹시 다른 CI/CD툴로 업데이트 해주시는 건 어떻게 생각하시는지요?  항상 감사히 많이 배우고 있습니다

개설한 EC2 인스턴스를 상시 실행이 아닌, 중지/재시작으로 관리하며 학습하고 있는 중입니다. (비용 때문에) 아마도 Elastic IP 서비스를 이용하지 않으면, 인스턴스 재구동시 IP 정보가 변경될텐데요, 앞서 Route 53 서비스를 통하여 도메인 레코드를 등록한 정보에 새로 구동된 인스턴스 서버의 IP 를 도메인 레코드로 재등록 (삭제/등록) 해줘야만 다시 정상 등록이 될 것으로 이해하고 있습니다. 궁금한 점은, 혹시 인스턴스만 중지시키고, 별도로 도메인 레코드 등록정보를 삭제하지 않았을 경우에 대한 문제점이나 비용 차징에 관한 정보를 자세히 알 수 있을까요?

vs code상 터미널에서 zsh이 쓰이고 있는 맥북이며 docker run -dp 3000:8080 -v /usr/src/app/node_modules -v $(pwd):/usr/src/app wkdzhd2000/nodejs 라고 입력했는데 컨테이너 ID가 나오지 않고 아래와 같이 형식에 맞지 않게 입력했다고 나옵니다. docker: invalid reference format. See 'docker run --help'.   맥북이기때문에 $(pwd)가 맞다고 생각하고 다른 부분에도 잘못 쓴 것이 없어보이는데 왜 인식하지 못할까요..? 구글링하며 몇몇 글이나 공식문서도 참조하고 있는데 아직까지 원인을 찾지 못하였습니다... 윈도우는 아니지만 혹시 몰라 ${pwd}하니 작동은 했습니다. 하지만 server.js의 소스코드를 바꾼다음 컨테이너를 docker stop 했다가 다시 run 해도 소스코드 변경내용이 반영되지 않는다는 문제가 생겼습니다..   어디가 잘못된 걸까요?? 저만 이러나요??
