curl 설치

안녕하세요 우선 좋은 강의 감사합니다!

현재 namespace 강의를 듣고 있는 중이고,

한 namespace 내 pod에서 다른 namespace의 pod ip로 curl 명령치는 테스트 실습해보고 있는데요

curl 명령어를 찾을 수 없다는 에러가 뜨는데, curl을 직접 설치하고자 apt update 부터 했는데요

아래와 같이 404 not found가 떠서요... 이런식으로 curl 설치하는게 아닌가요?

root@pod-1:/# apt update

Ign:1 http://deb.debian.org/debian stretch InRelease

Ign:2 http://deb.debian.org/debian stretch-updates InRelease

Err:3 http://deb.debian.org/debian stretch Release

404 Not Found [IP: 151.101.2.132 80]
