AWS의 Opsworks에서 새로운 instances를 만들다가 만난 에러를 정리해둡니다.
AWS의 Opsworks 는 인스턴스를 새로 생성하면 등록되어있는 Chef Recipe 들을 자동으로 실행해주는 툴입니다.
이번에 Instance 한개를 추가로 생성하고, 그 Instance에 하나의 App 을 배포하려고 기존 Layer에서 추가로 Instance 를 생성하게 되었습니다.
그런데 갑자기 에러가 발생해서 로그를 봤더니 이런 로그가 있었습니다.

해서 검색을 시작했습니다.
저는 OpsWorks나 Docker에 서툴러서 뭔 실수를 했나 싶었는데 결과는…
그냥 단순히 서버 다운… OTL.
p80.pool.sks-keyservers.net: Host not found
gpgkeys: HTTP fetch error 7: couldn’t connect: Success
그냥 저 서버가 죽은거 였네요.
저 서버가 Docker설치시 기본으로 바로보는 PGP key server인 듯..
아래 링크가 이 에러와 관련된 Thread입니다.
Key server down for get.docker.com · Issue #13555 · moby/moby · GitHub
여기 가보면 kris라는 사람이
기존 Docker가 사용하는 서버주소를
From,
p80.pool.sks-keyservers.net
To,
hkp://keyserver.ubuntu.com:80
로 변경해주라고 답을 달아놨더군요.
결론
아무튼 이 버그의 결론은,
잠시뒤에 다시 시도 해본다;;;;
서버가 살아날 시간을 주는 것입니다;;
