userdata 인스턴스 시작시 실행할 루비 스크립트가 잘못된 루비 버전을 사용합니다

Question

시작할 때 사용자 스크립트를 실행하고 싶은 인스턴스가 있습니다. 그래서

그래서 유저 데이터의 범위를 벗어난다 확인하기로 결정 :이 얻을 로그에 그러나

: 그래서 유저 데이터에서이 코드를 삽입 스크립트 내에서 "sudo gem install"이라고 부르더라도 잘못된 루비 버전의 보석을 설치합니다. 이것은 RVM이 없다. 어떤 루비 버전 (1.93 이상)이 실행되는지 신경 쓰지 않고, aws-sdk 젬을 사용해야합니다. 아이디어?

감사합니다. 예비 단계에서 설치

이 해결 :

runcmd를 : - "sudo는 보석 AWS-SDK를 설치"
