안녕하세요, 강사님강의 복습중입니다.한 가지 궁굼한 점이 있습니다.강의 외적인 부분인데iterm 세팅을 어떻게 하고 계신가요?커서 옮길때 매우 빠른(?) 속도를 갖고 계시던데테마 등 정보 공유 부탁드리겠습니다!아참,5월에 테라폼 강의 준비해주신다고 하셨는데...테라폼이 아닌, aws강의를 준비하셔서 조금 섭섭하네요.. ㅋㅋ

안녕하세요 스프링으로 개발하고 있는 뉴비인데, 최근에 golang에 흥미가 생겨서 강의를 듣게 되었습니다.이제 강의를 다 수강하고, gorm을 사용해서 db연결까지 해보려고 하는데, 궁금증이 생겨서, 강의의 범위를 벗어나지만 질문드리려고 합니다스프링에서는 서비스 계층에 트랜잭션을 선언후 그 안에서 벌어지는 db관련 로직들을 원자적으로 실행할 수 있습니다. 트랜잭션의 전파를 통해, 서비스에서 다른 서비스를 호출해도 하나의 트랜잭션으로 묶을 수 있고요. gin에서 동일한 결과를 내고 싶은데, 제가 찾은 방법 2가지가 있습니다 DB 객체를 서비스에서 필드로 보관하면서 repository를 호출할때마다 인자로 DB에 트랜잭션을 적용해 를넘겨준다 (또는 트랜잭션을 받는 wrapper function을 사용한다) => 코드작성량이 ㄷㄷrepository에 임시적인 WithTransaction(tx)메서드를사용해, repository의 DB가 임시로 트랜잭션을 바라보게한다. =>싱글톤에서 말도 안되는 방법인거 같은데 gpt가 강추함컨텍스트에 트랜잭션 DB객체를 담아 모든 곳에서 꺼내 사용한다 => gpt, google 모두 권장되지 않는 방법이라고 함3줄요약전부다 다 뭔가 이상한거 같아서, 실무에서 golang을 사용하면 서비스에서 다수의 DB접근이 필요하고, 이를 하나의 트랜잭션으로 관리해야될 때 어떻게 트랜잭션을 처리하는지 궁금합니다!!   

spring: datasource: url: "jdbc:mysql://localhost/library" username: "root" password: "비밀번호" driver-class-name: com.mysql.cj.jdbc.Driver위와 같이 application.yml 파일을 작성했는데, 사용자 등록을 하면 서버 내부 오류라고 뜨면서 아무것도 안되더라구요.개발자 도구로도 봤는데 뭐가 문제인지 잘 모르겠어서 구글을 찾아보다가 jpa: database: mysql hibernate.ddl-auto: update show-sql: trueapplication.yml 파일에 추가로 이걸 입력하니까 정상적으로 작동하네요.. 혹시 이렇게 두고 실행해도 괜찮은건지 여쭤보고싶었습니다!   

6월말 시험 신청했는데 강의 연장 부탁드리겠습니다

일부 event는 디폴트 브랜치에서만 동작한다고 하셨는데 디폴트 브랜치를 pr-test로 바꾸면 pr-test가 디폴트 브랜치니까 issue 생성 시 event가 일어나야 하는 것 아닌가요? 제가 잘못 이해한 걸 까요..?

강의연장부탁드려도될까요 6월 한달간 다 듣는 걸 목표로 하겠습니다 급하게 따야할 일이 생겼는데 미루다 이제 듣기 시작했네요부탁드리겠습니다..!! 감사합니다.

- 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?

불합을 해서 한번만 더 연장 부탁드립니다 감사합니다

deploy.yml github action 성공 했습니다, 그리고 main branch에 merge까지 완료했습니다 , 그리고 곧 바로 static ip : 4000 번 해서 들어가려 하면 들어가지지 않네요, AWS 들어가서 SSH키고 npm run start를 쳐야지 접속이 됩니다 , 이거 문제 있는거 맞죠 ? , 이러면 자동배포가 아니지 않나요 ?
