지금은 pickle에서 장고 모델 지원되는거 같습니다!! json은 여전히 Not Serializable 에러 뜹니다신기해서 공유드립니다

윈도우11 home을 사용하고있고 C:\html 경로에서 docker run 명렁어를 입력하였습니다.혹시 틀린 부분이 있을까요?  위 방법으로 해결은 되었습니다. 다만 무슨차이가 있는것이고 왜 문제가 발생한지 모르겠어요 그리고 또하나 질문이 있습니다. docker run으로 실행하였을때 위에 이미지 처럼 뜨게되는데 이 상태에서 컨트롤 + c / 컨트롤 + d를 입력해도 명령이 종료가 되지않는데 어떻게 종료할 수 있을까요?

자꾸 데이터베이스가 에러 나는데 뭐 때문인지 도무지 알 수가 없습니다...

안녕하세요,로컬에서 테스트 마치고 도커로 프로비저닝 작업하고 있는 중에 이슈가 생겨 문의드립니다.// Docker image build docker build --tag msa-api-gateway:1.0 . // Docker container run docker run -d -p 8000:8000 --network msa-network \ -e "spring.cloud.config.uri=http://config-server:8888" \ -e "spring.rabbitmq.host=rabbitmq" \ -e "eureka.client.serviceUrl.defaultZone=http://service-discovery:8761/" \ --name api-gateway \ msa-api-gateway:1.0위 커맨드로 api-gateway 도커 이미지 빌드 후 실행시 로그를 보니 connection failed 이슈가 발생해서 원인을 확인했는데요,-e 옵션으로 준eureka.client.serviceUrl.defaultZone=http://service-discovery:8761/이 반영이 안되고 기존 application.yml에 정의되어 있는 localhost:8761/eureka가 호출되어 문제가 되는 것으로 확인됩니다.(application.yml 내에서 직접 defaultZone 수정하니깐 정상 동작됩니다. 또 확인차 application.yml에선 service-discovery로 하고 -e 옵션으로 localhost로 설정하여 의도적으로 에러를 발생시키려고 했는데, 역시나 반영이 안되고 정상적으로 동작되었습니다.)참고로 application.yml은 별도 github에 정의되어 있고 config server로 가져오고 있는데요, 우선순위같은게 있을까요? 도움 부탁드립니다.(추가)기존에 application.yml에 spring.rabbitmq.host:127.0.0.1 로 되어있는 것에 -e 옵션으로 rabbitmq로 실행할 때도 반영이 안되네욥ㅠ application.yml에서 직접 rabbitmq로 수정해줘야 동작합니다.Config github 내에서 관리하는 api-gateway-server.yml 입니다.server: port: 8000 eureka: client: register-with-eureka: true fetch-registry: true service-url: defaultZone: http://service-discovery:8761/eureka # http://localhost:8761/eureka spring: application: name: api-gateway-server rabbitmq: # Spring Cloud Bus 적용을 위한 RabbitMQ host: rabbitmq #127.0.0.1 port: 5672 # rabbitmq admin port는 15672 username: guest password: guest cloud: gateway: default-filters: - name: GlobalFilter args: baseMessage: Spring Cloud Gateway Global Filter preLogger: true postLogger: true routes: - id: user-service uri: lb://USER-SERVICE predicates: - Path=/user-service/login # 로그인 - Method=POST filters: - RemoveRequestHeader=Cookie - RewritePath=/user-service/(?<segment>.*), /$\{segment} - id: user-service uri: lb://USER-SERVICE predicates: - Path=/user-service/users # 회원가입 - Method=POST filters: - RemoveRequestHeader=Cookie - RewritePath=/user-service/(?<segment>.*), /$\{segment} - id: user-service uri: lb://USER-SERVICE predicates: - Path=/user-service/actuator/** - Method=GET, POST filters: - RemoveRequestHeader=Cookie - RewritePath=/user-service/(?<segment>.*), /$\{segment} - id: user-service uri: lb://USER-SERVICE predicates: - Path=/user-service/** - Method=GET filters: - RemoveRequestHeader=Cookie - RewritePath=/user-service/(?<segment>.*), /$\{segment} - AuthorizationHeaderFilter - id: order-service uri: lb://ORDER-SERVICE predicates: - Path=/order-service/** - Method=GET,POST filters: - RemoveRequestHeader=Cookie - RewritePath=/order-service/(?<segment>.*), /$\{segment} - id: catalog-service uri: lb://CATALOG-SERVICE predicates: - Path=/catalog-service/** - Method=GET,POST filters: - RemoveRequestHeader=Cookie - RewritePath=/catalog-service/(?<segment>.*), /$\{segment} management: # springboot actuator(운영중인 어플리케이션 모니터링 기능) 옵션 설정 endpoints: web: exposure: include: refresh, health, beans, httptrace, info, busrefresh token: # User-service Spring Security 인증토큰 expiration_time: 86400000 secret: userTokenForMSASkeletonTemplateHS256LongerThan256Bytes  혹시 몰라 도커 에러 메세지 남깁니다. . ____ _ __ _ _ /\\ / ___'_ __ _ _(_)_ __ __ _ \ \ \ \ ( ( )\___ | '_ | '_| | '_ \/ _` | \ \ \ \ \\/ ___)| |_)| | | | | || (_| | ) ) ) ) ' |____| .__|_| |_|_| |_\__, | / / / / =========|_|==============|___/=/_/_/_/ :: Spring Boot :: (v2.7.5) 2022-12-28 20:50:19.284 INFO 1 --- [ main] c.c.c.ConfigServicePropertySourceLocator : Fetching config from server at : http://config-server:8888 2022-12-28 20:50:19.697 INFO 1 --- [ main] c.c.c.ConfigServicePropertySourceLocator : Located environment: name=api-gateway-server, profiles=[default], label=null, version=32b9a3dfd58bb8bb5ef5e7a412b2433fc2d94791, state=null 2022-12-28 20:50:19.699 INFO 1 --- [ main] b.c.PropertySourceBootstrapConfiguration : Located property source: [BootstrapPropertySource {name='bootstrapProperties-configClient'}, BootstrapPropertySource {name='bootstrapProperties-https://github.daumkakao.com/ch-svc-dev2/template-cloud-config/api-gateway-server/api-gateway-server.yml'}] 2022-12-28 20:50:19.708 INFO 1 --- [ main] c.a.ApiGatewayApplication : No active profile set, falling back to 1 default profile: "default" 2022-12-28 20:50:20.482 INFO 1 --- [ main] faultConfiguringBeanFactoryPostProcessor : No bean named 'errorChannel' has been explicitly defined.

antd 디자인 홈페이지에서도 똑같이 from 'antd'에서 가져오는데 최신버전이라 안먹히는것인지 Comment가 안불러와지네요. 자동완성도 지원이 안되고요

강사님 안녕하세요강의 항상 잘 보고 있습니다.강의 중에 궁금한 부분이 있어서 질문드립니다.HPA 기능을 사용하기 위해서 Metric Server를 설치하는데 이전 수업에서kube-scheduler 설명할때는kube-scheduler가 api-server에 watch를 걸어놓고 모든 node의 cpu/mem등의 리소스 상황을 파악하여파드생성등의 요청이 있을때 목적지를 선정해주는 역할이라고 들었습니다. 그럼 metric server를 설치를 안해도 api-server를 통해 cpu/mem 정보를 알수 있지 않나 싶은데HPA를 사용하기 위해서 metric server를 설치하는 이유가 있을까요?HPA에서 metric api를 사용한다는 것은 알고 있는데kube-scheduler처럼 metric server를 통하지 않아도 cpu/mem 정보를 얻을수 있지 않을까싶어서 여쭤봅니다.

강사님 블로그 글이 있어서 자답합니다.ㅎㅎ

강사님 안녕하세요동일 클러스터 내에 worker node에서master node의 /root/.kube/config 파일내용을확인할 수 있는 방법이 있을까요?

 안녕하세요 선생님첫화면엔 커넥션 리퓨즈 뜨고회원가입 누르면 이러한 오류가 뜹니다 넘어가질 않고 오류가 계속나오는데 왜이런걸까요?..무엇이 문제인지 궁금합니다:4000 으로 계속 찍히는거 보면 cors가 안되는것일까요강의보고 다 제대로 따라했는데 ㅠㅠ도와주시면 감사하겠습니다

제가 이해한게 맞는지 확인 부탁드립니다.가상머신이나 컨테이너가 큰 기술적 개념이라고 생각하는데요도커라는 말은 제품명이라고 이해하면 될까요?예를들어서 저는 가상머신이 기술적 개념이라면 이를 제품화한게 Virtual Box, VMware라고 생각합니다

선생님 포스트 나 댓글 삭제기능은 어떤식으로 해야될까요 따로 강의는 없겟죠? ㅠ

안녕하세요 선생님post 타이틀을 한글로 쓰면 경로이동이 안됩니다 영어로 쓰면 라우터대로 경로가 이동하는데 한글로 쓰면 이동이 안되네요... 왜이럴까요 한글타이틀 도 영어타이틀 처럼 잘 이동될순 없을까요  

강사님 안녕하세요 궁금한 부분이 있어서 질문 드립니다.Logging 챕터에 cAdvisor에 대한 설명과 프로메테우스등의 솔루션 내용이 나오는데요Daemonset을 통해서 프로메테우스 파드들이 각 노드에 설치되는 것을 확인했습니다.그런데 matrics server를 설치하면각 노드의 kubelet이 matrics 정보를 API 서버로 주기 때문에 master 노드에서도kubectl top 명령으로 성능 정보를 확인할 수가 있다고 본거 같은데요그러면 Daemonset으로 모든 노드들에 파드들을 배포할 필요 없이master 노드에서만 Agent를 설치하여 모든 노드들의 성능정보를 수집하는 것이 가능할까요?왜 데몬셋을 통해 모든 노드에 Agent를 배포해야 하는지 궁금합니다.또 프로메테우스에서 데몬셋으로 노드별로 파드를 배포하는데노드의 matrics 정보가 아닌 클러스터 구성정보(노드 수, 네임스페이스, 파드 수)는 API Server를 통해서 수집을 하게 되는건가요?그럼 노드마다 배포된 파드에서 API Server를 통해 정보를 수집하게 되면(1번노드에서 수집, 2번노드에서 수집) 구성정보는 중복 수집이 될텐데API Server로부터 구성정보를 수집하는 파드가 별도로 있을까요?

배포하기 전에 커뮤니티, 포스트, comment 삭제하고 다시작성하고 싶은데 어떻게해야될까요?

docker-compose up이후에 build는 다 되서 메인페이지는 열리지만 이렇게 에러가 납니다. 제가 한게 이상한가 싶어서 깃허브에 있는 코드로 docker-compose up해도 저런 오류가 나는데 무슨 문제인지 궁금합니다..!

DetailVIew 및 ListView 에서as_view() 할때 model, template_name_field, template_name 등등 상속으로 받은 클래스 변수를 초기화 해줍니다.여기서 질문은제가 클래스를 만들어 위 내용에 동일한 클래스 변수 생성하여 다중 상속하고 classmethod를 선언하여 메소드에 상속 된 변수를 선언할려고 하는데 코어에 as_view() 처럼 무엇이 상속되었는지 표시가 나오지 않습니다. 해당 내용에 대한 해결 방법에 대해 질문드립니다.아래 내용은 스크린샷 입니다.코어에서 as_view()제가 만든 함수  

안녕하세요. 강의 잘 듣고 있습니다!배포 후 AWS에서 에러난 것을 수정 해주신 코드 보며 잘 해결했습니다.궁금한 점이 docker-compose.yml 내부 코드를 수정하고 나서 다시 터미널에 docker-compose up --build를 해서 컨테이너를 만들고 깃허브에 푸쉬를 해야 하는 지 아니면 바로 깃허브에 푸쉬하면 되는 것인지 궁금합니다.이번에는 혹시 몰라서 빌드를 하고 푸쉬하니 배포는 잘 됐습니다!

TypeError: dispatch is not a functionat handleSubmit (login.tsx?11e1:23:13) 에러나는 부분은login파일의 dispatch("LOGIN",res.data?.user); 에서 에러가 납니다. 이 강의 듣는 몇몇분들도 동일하게 나타나는 증상같은데.. 확인 한번 부탁드립니다.

nginx 웹서버 설정 이해1 4분43초nginx 설치를 위하여 아래와 같은 명령어 실행 ->apt-get install nginx=1.18.0-0ubuntu1해당 명령어 실행 후, E: Version '1.18.0-0ubuntu1' for 'nginx' was not found식으로 찾을 수 없다라는게 뜬다면아래와 같이 코드를 변경 요망. apt-cache policy nginx명령어를 치시면 Installed: 1.18.0-0ubuntu1.4식으로 나오는데, 해당 위 버전으로 변경해 줘야합니다.apt-get install nginx=1.18.0-0ubuntu1.4으로..해당 버전은 계속 변경되고있는 부분이라.혹 안되는 분 있을까봐 공유드립니다. 이상입니다.ps.좋은강의입니다.듣고있는데 너무 친절하시네요, 완강까지 다들 화이팅 입니다.
