인프런 커뮤니티 질문&답변

현재 docker toolbox를 이용중입니다..

docker toolbox는 가상머신에 서버를 뛰우기에

디폴트 ip인 192.168.99.100 으로 이전 강의(jpa, postgre 등)에서 application.properites에 설정하여

정상적으로 작동하였습니다. redis사용할 때도 설정이 필요한지 질문드립니다. 

우선 아무설정없이 실행하면 아래에러가 뜨는데 이 설정이 없어서 나는 문제인지 알고싶습니다.

강의를 듣다가 막혀서 진도가 안나가 질문드립니다.

아래 에러메시지를 나열하였습니다.  감사합니다.
