어플리케이션 실행시 에러

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.

Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.
