The guest machine entered an invalid state while waiting for it to boot. Valid states are 'starting, running'. The machine is in the 'aborted' state. Please verify everything is configured properly and try again. If the provider you're using has a GUI that comes with it, it is often helpful to open that and watch the machine, since the GUI often has more helpful error messages than Vagrant can retrieve. For example, if you're using VirtualBox, run `vagrant up` while the VirtualBox GUI is open. The primary issue for this error is that the provider you're using is not properly configured. This is very rarely a Vagrant issue.virtual box 버전이 최신에서만 m1이 되다보니.. 안되는 거 같습니다.

안녕하세요, podman으로 환경 구성을 하던 중 질문이 있습니다.root 계정에 podman을 설치하고 이미지를 pull해와서 컨테이너를 빌드해봤습니다.그리고 나서 다른 user로 접속하여 이미지와 컨테이너를 검색해보니 아무것도 보이지 않습니다.docker에서는 docker 그룹에 user를 추가하여 사용하였는데 podman group은 없는것 같네요...?!임의로 sudo podman images 해주니까 보이긴 합니다.모든 계정에서 동일한 이미지와 컨테이너를 보려면 어떻게 해야되나요?다른 user계정에 root권한을 주지 않고 가능한 방법이 있을까요?

[질문 전 답변]1. 강의에서 다룬 내용과 관련된 질문인가요? [예 | 아니요]2. 인프런의 질문 게시판과 자주 하는 질문에 없는 내용인가요? [예 | 아니요]3. 질문 잘하기 법을 읽어보셨나요? [예 | 아니요](https://www.inflearn.com/blogs/1719)4. 잠깐! 인프런 서비스 운영 관련 문의는 1:1 문의하기를 이용해주세요.[질문 하기]안녕하세요! 조훈님 쿠버네티스 강의 너무 재밌게 듣고 있는 수강생입니다. 다름이 아니라 제가 오늘 트러블 슈팅하는 과정에서 무작정 해결은 되었지만 원인을 정확하게 알수 없어서 조훈님께 좀더 정확한 지식을 얻기 위해 질문합니다!저의 문제 상황은 이러했습니다. 강의 대로 진행을 하면서 LoadBalance로 배포를 하니 ip가 192.168.2.11 로 배포가 되더라고요. 때문에 접속이 불가능 했고, 저는 위 ip를 강의와 같이 192.168.1.11 바꾸고 싶었습니다. 때문에 조훈님 강의를 다시 반복하면서 제가 놓친 부분이 있나 보기도 하고, 강의 질문목록등을 살피면서 metallb.yaml파일을 열어 보았고 마지막 부분이 이렇게 강의와 다른 ip를 가르키고 있었습니다. data: config: | address-pools: - name: metalLB ip-range protocol: layer2 addresses: - 192.168.2.11-192.168.2.19파일을 처음 열어보았을 때 어? 이 주소가 맞나? 싶었습니다.하지만 저는 제 지식이 짧은 탓에 이 부분을 건드려도 되는지 확인해 보기 위해 조훈님 깃헙 파일과 대조해 보았고 놀랍게도 깃헙 파일은 192.168.2.11-192.168.2.19이 아닌 192.168.1.11-192.168.1.19로 되어 있더라고요. 이게 어찌된 일인지.. 저는 yaml 파일을 건드린 적이 없는데... 때문에 수정을 위와 같이 해서 강의와 같이 ip를 바꾸긴 했지만 왜 yaml 파일이 지 멋대로 수정이 되어있었는지 아직도 의문입니다. 제가 나름대로 추측(?)을 해보았는데 이 부분에서 조훈님께서 제가 어떤 부분 지식이 부족한지 방향성을 알려주실 수 있다면, 제가 놓친 부분을 더 공부하고자 합니다![추측]위와 같이 yaml 파일이 수정이 된것은 제가 virtualbox를 삭제하고 meatallb image가져오기를 반복하는 과정에서 무슨 문제가 있지 않았을까 생각합니다. (서버 재대로 끄지도 않고, 그냥 virtualbox 삭제 안되는거 강제로 삭제하고 다시 apply -f 무작정 다시 하고 그랬습니다.)

올려주신 chatapp 프론트 엔드의 migrations yaml 파일을 hasura cli migrations v3 에 맞게 수정해주실 수 있나요?git에 올려주신 migrations 파일 내용이 현재 hasura 버전과는 호환이 안되어서 테이블 생성이 안됩니다.우선 저는, hasura 이미지 버전 "hasura/graphql-engine:v1.3.4-beta.3.cli-migrations" 으로 바꾸는 방법으로 해결을 하긴했는데요, 바람직한 방법은 아니라고 생각해요.올려주신 chatapp 프론트 엔드의 migrations yaml 파일을 hasura cli migrations v3 에 맞게 수정해주실 수 있나요?시간을 들여서 수강자가 고치면 되긴하나 강의의 의도와는 멀어지기도 하고, 바꿔서 하는 것 조차 강의의 의도라고 하신다면, 최소한의 답안 정도는 있어야 한다고 생각해요.

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?

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

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
