- name: S3에 프로젝트 폴더 업로드하기 run : aws s3 cp --region 과정을 통해서 압축된 tar.gz 파일은 s3에 저장한다고 이해했는데 따로 압축해제하는 과정이 없어서 질문드립니다. run: aws s3 cp --region ... 다음 S3에 프로젝트 폴더 업로드 하는 과정에서 s3에서 해당 파일을 받고 난 후에 알아서 압축해제를 하는건가요?? 

dto에서 request를 구성할 때에 Create와 Update에 대한 request를 두 개로 나누어 구성하시는 것을 봤습니다.제가 생각하기에 user 테이블에 접근하여, userService에 사용되기 위한 것이니 UserRequest라는 클래스를 만들어 하나로 통합하여 사용하면 보기 편하고 사용하기 쉬울 것 같습니다.성능에서 차이가 있다던지 request를 따로 구별해서 사용하신 이유가 있는지 궁금합니다.

강사님 안녕하세요artillery로 부하테스트를 하던중로컬에서는 성공했지만, 배포환경에서는 정상작동하지 않아해결법을 찾는중입니다강의에서는 artillery의 버전이 나오지 않는데요아마도 제가 설치한 버전과의 차이도 원인이 될 수 있을거라 생각이 되는데, 강의시 설치된 버전을 알 수 있을까요(강의 너무 재밌게 잘 보고 있습니다!)

안녕하세요.요즘에 'aws lightsail 로 프로젝트 옮기기'를 듣고 있습니다.거기서 블로그 글을 참고하라고 하셔서, 블로그를 들어갔더니, 해당 블로그 게시판이 작동하지 않습니다.확인 부탁드려도 될까요? 감사합니다.

ci/cd가 끝난 후 ec2에서 docker ps 명령어를 쳤는데 컨테이너가 실행되지 않습니다. docker ps -a 명령어로 보니 status 가 Exited로 나오네요.ec2 사양은 t2micro 로 했는데 이 영향이 있을까요?

최근에 회사일이 바빠 강의를 들을 여력이 없었습니다.가능하다면 수강 기간 연장 가능할까요?

EKS hands-on with CloudNet@의 "4장 실습 프로메테우스와 그라파나 구성하기" 에서"1.1. 프로메테우스 스택 설치"의 "프로메테우스 스택 설치" 진행 후"crd, servicemonitors, targetgroupbindings 확인"의"kubectl get targetgroupbindings -n monitoring" 명령어 조회 시,(admin@myeks:default) [root@myeks-bastion-EC2 ~]# kubectl get targetgroupbindings -n monitoring No resources found in monitoring namespace  AWS Home Page의 EC2 Load balancers에서 Listener 조회 시, 443 Target 확인 되지 않는 현상.상기 Issue의 Solution은 아래와 같습니다. (CloudNet@ Team의 노고에 감사 드립니다.) Prometheus Stack을 배포함과 동시에 ALB는 Listener를 지정 후 Targetgroup 정보를 수신 합니다. 이때, 실습에서 생성한 AWS Certification Manager (略 ACM) 정보를 기반으로 합니다.(AWS Console Home에서 "Certification Manager" 로 검색하여 찾을 수 있습니다.) 만일, 실습 진행 간 배포한 Stack을 삭제 후 재 생성 한 경우, ACM에 대한 기존의 생성 정보를 호출,재차 변수로 반영하는 작업에서 추가로 생성 후 ACM을 변수로 반영하고자 하면,기존의 Issued 된 ACM이 추가 생성에 의한 Pending Validation 상태인 ACM을 기준으로 등록합니다. 또한, 재차 생성된 ACM은 Status가 변경 즉, Issued가 되기까지 일정 시간이 소요 되며,그 전에 Prometheus-stack 배포를 시도 할 경우, ACM 값을 호출하지 못하여 아래와 같이 표시 됩니다. ADDRESS (myeks-ingress-alb-123456789.ap-northeast-2.elb.amazonaws.com) 확인 불가Every 2.0s: kubectl get pod,svc,ingress,pv,pvc -n monitoring NAME CLASS HOSTS ADDRESS PORTS AGE ingress.networking.k8s.io/kube-prometheus-stack-grafana alb grafana.example.net 80 6m57s ingress.networking.k8s.io/kube-prometheus-stack-prometheus alb prometheus.example.net 80 6m57s 따라서 ACM 메뉴에 진입하여 기존의 생성된 ACM을 전부 삭제하고, ACM을 재차 생성하여 변수로 선언,Prometheus-stack을 삭제 후 재 배포시 성공적으로 주소가 할당 되는 것을 확인 할 수 있습니다.재 생성 후 일정 시간 소요 시 Issued를 확인 하고, ACM 선언 및 변수 적용 절차를 재차 수행 합니다.// Prometheus stack & PV with PVC Uninstallation // (admin@myeks:default) [root@myeks-bastion-EC2 ~]# helm uninstall -n monitoring kube-prometheus-stack release "kube-prometheus-stack" uninstalled (admin@myeks:default) [root@myeks-bastion-EC2 ~]# kubectl delete pvc prometheus-kube-prometheus-stack-prometheus-db-prometheus-kube-prometheus-stack-prometheus-0 -n monitoring persistentvolumeclaim "prometheus-kube-prometheus-stack-prometheus-db-prometheus-kube-prometheus-stack-prometheus-0" deleted // ACM Renewing // (admin@myeks:default) [root@myeks-bastion-EC2 ~]# aws acm list-certificates { "CertificateSummaryList": [ { "CertificateArn": "arn:aws:acm:ap-northeast-2:398561966751:certificate/4a83d353-c8f1-4418-a007-3ad49eb5d7fd", "DomainName": "*.example.net", "SubjectAlternativeNameSummaries": [ "*.example.net" ], "HasAdditionalSubjectAlternativeNames": false, "Status": "ISSUED", "Type": "AMAZON_ISSUED", "KeyAlgorithm": "RSA-2048", "KeyUsages": [ "DIGITAL_SIGNATURE", "KEY_ENCIPHERMENT" ], "ExtendedKeyUsages": [ "TLS_WEB_SERVER_AUTHENTICATION", "TLS_WEB_CLIENT_AUTHENTICATION" ], "InUse": false, "RenewalEligibility": "INELIGIBLE", "NotBefore": "2024-05-22T09:00:00+09:00", "NotAfter": "2025-06-21T08:59:59+09:00", "CreatedAt": "2024-05-23T00:10:55.366000+09:00", "IssuedAt": "2024-05-23T00:13:12.752000+09:00" } ] } // ADDRESS VALIDATION // Every 2.0s: kubectl get pod,svc,ingress,pv,pvc -n monitoring NAME CLASS HOSTS ADDRESS PORTS AGE ingress.networking.k8s.io/kube-prometheus-stack-grafana alb grafana.example.net myeks-ingress-al b-123456789.ap-northeast-2.elb.amazonaws.com 80 20m ingress.networking.k8s.io/kube-prometheus-stack-prometheus alb prometheus.example.net myeks-ingress-al b-123456789.ap-northeast-2.elb.amazonaws.com 80 20m

안녕하세요 섹션9의 프론트 소스코드를 보고싶은데 강의자료에는 안 올라와 있어서 이렇게 질문으로 남겼습니다,,,

문제 3번 풀던 중 생긴 오류를 잡으면서 생긴 의문입니다. DTO에 List를 만들어서 JSON 배열을 POST형식의 body로 받는 문제였습니다.아래는 변수를 final로 선언했을 때 생기는 오류입니다.ERROR 8512 --- [nio-8080-exec-1] o.a.c.c.C.[.[.[/].[dispatcherServlet] : Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is org.springframework.http.converter.HttpMessageConversionException: Type definition error 선언하는 방식에 문제가 없다고 여겨 수정해보다가 final과 constructor를 지우고 다시 요청을 날려보니 정상적인 값의 출력을 확인했습니다.이 final과 constructor 이 무슨 역할을 하고 있는지, 왜 final로 선언되었을 때는 오류가 났는지, 언제 사용되어야 하는지 등 검색을 해보지만 잘 이해가 되지 않아서 질문 남깁니다. 

ECS FARGATE 생성시 ALB 생성에서 자꾸 에러가 발생해서 질문드립니다. 로그를 타고 들어가보니 서버동작은 올바르게 되는 것으로 보이는데, 로드밸런서의 타겟그룹이 unhealthy가 되네요. vpc는 자동생성 마법사로 생성한 것으로 가용역역 a,b에 각각 private/public 서브넷이 한개씩 존재하는 형태입니다.검색을 해보니 이 형태로는 alb 부착이 안되는 것 같아서 Nat게이트웨이를 연결해서 private 서브넷으로 시도 해봤는데 차도가 없네요.vpc와 서브넷에 대한 이해가 부족하여 질문드립니다. 혹시 alb 부착을 위한 간단한 가이드라인을 주실 수 있을까요?이미 완성되어 있는 프로젝트를 배포하는 거라 redis cloud를 사용중인데 이 경우 redis service는 하지 않아도 되는지 궁금합니다. 일단 cicd는 제쳐두고 dockerfile 환경변수를 직접 정의해 놓아 github에 올리지 않은 상태입니다.

 안녕하세요! Spring Security 적용하는 강의를 보면서 제가 사용하는 스프링 버전에 맞춰서 진행을 하고 있는데 defaultSuccessUrl 설정하는 부분에서 오류가 발생하여 해결을 하긴 했으나, 이상한 것 같아서 질문 드립니다. 기본적으로 SecurityConfig.java 코드는 다음과 같이 동일하게 작성해주었습니다. @Bean public SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception { return http .csrf(AbstractHttpConfigurer::disable) .authorizeHttpRequests(registry -> registry .requestMatchers("/auth/login").permitAll() .anyRequest().authenticated()) .formLogin(configurer -> configurer .loginPage("/auth/login") .loginProcessingUrl("/auth/login") .usernameParameter("username") .passwordParameter("password") .defaultSuccessUrl("/")) .userDetailsService(userDetailsService()) .build(); } 다음과 같이 Bean 등록을 통해 로그인을 성공하였을 경우, "/" 경로의 Controller를 호출하게 될 줄 알았습니다. 하지만, 다음과 같이 405 에러가 발생했습니다. 이상해서 로그를 살펴보니 Request received for POST '/' ... 라는 로그가 보입니다.그렇다보니, 제가 작성한 MainController에 있는 @GetMapping("/")이 요청을 처리하지 않아요.@RestController public class MainController { @GetMapping("/") public String main() { return "This is Main Page!!"; } } @PostMapping 으로 변경하여 진행을 하였을 경우 정상적으로 반환이 되기는 합니다.하지만 호돌맨님 강의에서는 Get 요청으로 받았고 정상적으로 처리가 되었지만, Post로 받아야 하는지 모르겠어서 질문 남깁니다.. 혹시 제가 잘못한 부분이 있다면 알려주시면 감사하겠습니다! 깃허브 주소는 아래에 남겨두겠습니다.깃허브 repository : https://github.com/f1v3-log/f1v3-back
