질문 답변을 제공하지만, 강의 비용에는 Q&A는 포함되어 있지 않습니다.
다만 실습이 안되거나, 잘못된 내용의 경우는 알려주시면 가능한 빠르게 조치하겠습니다!
[질문 전 답변]
1. 강의에서 다룬 내용과 관련된 질문인가요? [예]
2. 인프런의 질문 게시판과 자주 하는 질문에 없는 내용인가요? [예]
3. 질문 잘하기 법을 읽어보셨나요? [예]
(https://www.inflearn.com/blogs/1719)
4. 잠깐! 인프런 서비스 운영 관련 문의는 1:1 문의하기를 이용해주세요.
5. vagrant up
에서 발생하는 문제는 주로 호스트 시스템(Windows, MacOS)과 연관된 다양한 조건에 의해 발생합니다. 따라서 이를 모두 제가 파악할 수 없어서 해결이 어렵습니다. vagrant up으로 진행이 어렵다면 제공해 드리는 가상 머신(VM) 이미지를 import해서 진행하시기 바랍니다.

[질문 하기]
안녕하세요 예전에 강의를 들을 때에는 당장 쓸 일이 없어서 듣고 까먹었다가 이제 쓸 일이 생겨서 다시 공부 중인데 따라서 진행하다가 막혀서 질문드립니다.
`6.2 쿠버네티스 기본 오브젝트`강의의 8분 지점에서
root@cp-k8s:pwd
/root/_Lecture_k8s_starter.kit/ch6/6.2
root@cp-k8s:~/_Lecture_k8s_starter.kit/ch6/6.2# k apply -f ./dpy-chk-log.yaml
# 위의 명령어를 수행
root@cp-k8s:~/_Lecture_k8s_starter.kit/ch6/6.2# k get pods

dpy-chk-log-6b765b4569-rrj9p 0/1 ContainerCreating 0 70m
위와 같이 1시간이 지나도 생성이 안되는 문제 발생.
이전까지의 강의를 다시 들으면서 했을 때 다른 deployment는 apply로 했을 때 정상적으로 생성이 되었습니다.
혹시 강의가 업데이트 되면서 따로 수정해야 하는 사항이 있었을까요?

위와 같이 이전에 실행해야하는 스크립트는 수행했습니다.
아래 현재 상황을 추가 작성합니다.

이런 에러가 있는데 어떻게 처리해야할 지 모르겠어서 질문드립니다. 감사합니다.

안녕하세요...
아...우분투로 변경되면서 CentOS와 명령어 구성 및 권한 설정이 약간 틀려졌습니다.
그래서 nfs-exporter.sh 를 nfs_exporter.sh로 변경했는데... 여기에는 적용이 안된거 같습니다.
번거로움을 드려서 양해 말씀드립니다. ㅠ ㅠ
rerepo를 하셔서 다시 실행해 보시면 문제 없이 진행이 가능하실 겁니다. ㅠㅠ
혹시 변경된 파일의 비교를 원하시면 다음의 내용을 참조 부탁드립니다.
아하 클론 내려온지 얼마 안 지났어서 다 최신 내용일 줄 알았는데 그 뒤로도 수정되었군요!
강의 및 자료 업데이트해주셔서 항상 감사합니다!
