해당 스프링부트 코드 해석 좀 부탁드립니다..

api의 첫번째 호출 이후부터 antd Button 렌더링 안되는 이슈가 있습니다.

```jsx import { Popover, Modal, Button, Image, Result } from "antd"; const [prevImg, setPrevImg] = useState(["any"]); const [loading, setLoading] = useState(false); const [removeImgFiles, setRemoveImgFiles] = useState([]); const combinePrevImages = (prevImages, newImages) => { const combinedImages = [...prevImages, ...newImages]; return combinedImages; }; useEffect(() => { const postSeg = async () => { try { const res = await axios.post( "apiurl", { filepath: filePath, clips: sortableList.map(list => `${list.seg.start}-${list.seg.end}`), frame: frameValue }, { proxy: false } ); return res.data; } catch (error) { console.error("Error posting segments:", error); return []; } finally { setLoading(false); } }; const postSegments = async () => { if (segments[0]?.start === 0 && segments[0]?.end === 0) return; if (sortableList && filePath) { setLoading(true); const res = await postSeg(); const combinedPrevImg = combinePrevImages(prevImg, res.results); setPrevImg(combinedPrevImg); console.log("Post Request Success"); } }; postSegments(); }, [filePath, segments, frameValue]); const handleModalOpen = useCallback(() => setModalOpen(true), []); const handleModalClose = useCallback(() => { setRemoveImgFiles([]); setModalOpen(false); }, []); const handleDeleteButtonClick = async () => { if (removeImgFiles.length > 0) { setPrevImg([...removeImgFiles]); setRemoveImgFiles([]); } else { const result = await showSwal({ title: "Are you sure delete?", showCancelButton: true, confirmButtonText: "Confirm", cancelButtonText: "Cancel", confirmButtonColor: "#3085d6", cancelButtonColor: "#d33" }); if (result.isConfirmed) { setRemoveImgFiles([...prevImg]); setPrevImg([]); } const success = await Promise.all(removeImgFiles.map(deleteFiles)); return success; } } const handleRemoveFinish = async () => { if (removeImgFiles) { for (const filePath of removeImgFiles) { try { await removeFile(filePath); } catch (e) { console.log("File Remove Error", e); } } } setRemoveImgFiles([]); handleModalClose(); }; return ( <motion.div initial={{ x: width }} animate={{ x: 0 }} exit={{ x: width }} transition={mySpring} > <div style={{ fontSize: 12, padding: "0 5px", color: "var(--gray12)", display: "flex", justifyContent: "space-between", alignItems: "center" }} > <FaAngleRight title={t("Close sidebar")} size={20} className="angle-right" role="button" onClick={toggleSegmentsList} /> {header} <FaExpandArrowsAlt title={t("Image Inspection")} size={18} className="expand-arrow-alt" style={{ cursor: "pointer" }} role="button" onClick={!loading ? handleModalOpen : handleModalClose} /> <Modal title={t("Image Inspection")} centered onCancel={handleModalClose} open={modalOpen} footer={[]} width="100%" > <div className="imagecontainer"> <Button danger className="toggle-remove" onClick={handleDeleteButtonClick}> {removeImgFiles.length > 0 ? "Add" : "Remove"} </Button> {prevImg?.length > 10 && prevImg.map(img => ( <Popover key={img}> {removeImgFiles?.includes(img) ? ( <span> <Result className="result" icon={<FaSmile />} subTitle="delete" /> </span> ) : <Image key={uuidv4()} src={img} preview={{ src: img }} alt={uuidv4()} /> )} </Popover> ))} </div> <Button block onClick={handleRemoveFinish}> Finish </Button> </Modal> </div> ) ``` api 호출을 통해 frameValue 개수(여기서는 12개씩) 만큼 이미지를 렌더링 하고 있는데 두번째 호출부터는 Button이 렌더링되지 않아서 어디가 잘못됐는지 알고싶습니다.. 필요한 부분이 imagecontainer 클래스네임인 div를 렌더링 해야합니다.

AWS Beanstalk 배포 하기 전에 신경써줘야 할 것이 있나요 ?

현재 nodejs로 백엔드를 구성하고 EB에 배포하는데 몇 가지 오류가 생겨서 질문 드립니다. 프로젝트 구조는 다음과 같습니다. -customer └ .gitignore └ .dockerignore └ src ( 백엔드 코드 ) └ .gitignore └ Dockerfile └ Package.json -product └ customer 와 동일 -shopping └ customer 와 동일 -proxy └ Dockerfile docker-compose.yaml 리전 ap-northeast-2(seoul region) 로컬에서 빌드하고 작동하는 거 확인 후 위 코드를 모두 압축해서 EB에 올렸습니다. EB에 올리기전에 vpc , igw, 등등 미리 생성해줘야 할 게 있나요? 추가로 .gitignore 같은 파일도 같이 올려도 되나요 ? ( 초보라서 질문의 질이 떨어질 수 있지만 고수분들의 너그러운 양해를 부탁드립니다 .ㅠㅠ ) 에러 로그를 보면 1. ELB Fail -> VPC has no internet gateway 2. Stack named 'awseb-e-33wucpgpey-stack' aborted operation. Current state: 'CREATE_FAILED' Reason: The following resource(s) failed to create: [AWSEBV2LoadBalancer, AWSEBInstanceLaunchWaitCondition] 3.

mediasoup를 ELB 환경에 적용하여 배

안녕하세요 mediasoup를 이용해서 웹개발 프로젝트를 진행중인 백엔드 개발자 (초보자/갓 배우는중) 입니다. 말그대로 1:N 화상채팅이 포함된 기능을 구현중인데, mediasoup가 ELB배포환경에서 작동하고 있지않아서 여기에 질문올려봅니다ㅜㅠ 아래, 시도해본것과 상황 등을 정리해본 내용을 첨부합니다! 제가 뭘 더 확인해볼수있을까요ㅜㅠㅠ?? 답변주시면 정말감사합니다!! (현재 nodejs로 express이용해서 백서버 구성하고있습니다!) -------------------------------------------------------------------------------- [상황] -> 1:N 화상통화 구현을 위하여 mediasoup를 이용 -> local에서 잘 작동 -> docker 로 local에서 돌리면 잘 작동 (announceIP를 도커 기본 IP "127.17.0.1"로 작동) -> front-vercel배포, server-local 잘 작동 -> server에서 비디오와 오디오를 보내주고 있지 않는 상황 [예상하고있는 문제] -> mediasoup는 연결이 완료되면 2000-2020 포트로 video를 보내주는데, 이부분 포트가 안열리는게 아닐까? -> announceIP에 적절한 IP를 넣지 않아서 안열리는게 아닐까? [배포환경] alb application loadbalance + docker [열어본 port 2000-2100; 2000-2100/udp] - EC2 - Elastic beanstalk 리스너 - proxy (nginx) - docker [시도해본 예상 announce Ip] - EC2 publicIP - dockerIp [mediasoup 공식문서] https://mediasoup.org/documentation/ [참고한 mediasoup영상 및 깃헙] => 유트브 https://www.youtube.com/watch?v=oCzq82xVnkU => 깃허브 https://github.com/jamalag/mediasoup3 [현재 깃허브] https://github.com/4simsimhae/Back - mediasoup4 branch 입니다!

React EC2배포 시 nginx, pm2 궁금합니다 !

안녕하세요 ! React 프로젝트를 AWS EC2 통해서 배포하고있는데 궁금한 사항이 생겨 이렇게 글 남깁니다 ! 현재 구조는 ELb에서 http 80포트는 https 443포트로 리디렉션, 그리고 https 443 포트는 EC2 nginx가 있는 80포트로 보내주면 nginx는 React 3000 포트로 포트포워딩해서 보여주게 됩니다 ! 여기서 혹시 ELb 쪽에서 요청이 들어왔을때 EC2 nginx가 있는 80포트가 아닌 React가 있는 3000번 포트로 바로 보내주고, pm2를 통해서 React 프로젝트를 관리할경우 nginx의 역할이 사라지는거 같은데… 1. 혹시 저러한 구조로 변경할경우 nginx의 역할 혹은 사용시 이점이 따로 있을까요?! 2. 저러한 구조에서 ELB 를 사용하지 않고 http 80, https 443 요청을 nginx 쪽에서 핸들링해서 https 요청을 적용하는것도 가능한지 궁금합니다 ! 질문이 약간 혼란스러운거 같아서 죄송합니다 ㅜㅜ

이런것도 AWS 신입 포폴로 사용할 수 있을까요?

우선 제 글을 읽어주셔서 감사하다는 말씀부터 올립니다. 일종의 시나리오를 구상해서 그것에 관한 보고서를 작성하는 것인데요 고가용성 환경의 웹사이트를 구축하고 (인스턴스, ELB, AMI, 배치그룹, VPC, 오토스케일링, CloudWatch 사용) 일부러 여러 강도의 부하를 줘서 오토스케일링과 로드밸런서의 변화에 대한 보고서를 작성한다던지 Elastic beanstalk 을 사용함에 있어 v1 사이트를 배포 후 v2 사이트로 변경 하는 과정에서 문제가 발생해 다시 v1으로 변경하는 시나리오를 작성한것과 같은 보고서 형식을 AWS 포트폴리오로 사용할 수 있을까요?
