Compose: docker-compose의 일관되지 않은 환경 해석

이 명령으로 tomcat의 공식 이미지를 실행하는 경우:

도커 실행 -d -e JAVA_OPTS="-Xms5000m -Xmx10000m" 바람둥이:8
바람둥이 성공적으로 시작

하지만 이 콘텐츠로 docker-compose.yml을 만들면

tomcat:
  image: tomcat:8
  environment:
    - JAVA_OPTS="-Xms5000m -Xmx10000m"

그런 다음 실행합니다.

docker-compose up

나는이 출력을 얻는다 :

Recreating temp_tomcat_1...
Attaching to temp_tomcat_1
tomcat_1 | Invalid initial heap size: -Xms5000m -Xmx10000m
tomcat_1 | Error: Could not create the Java Virtual Machine.
tomcat_1 | Error: A fatal exception has occurred. Program will exit.
temp_tomcat_1 exited with code 1
Gracefully stopping... (press Ctrl+C again to force)

어떤 아이디어가 잘못 되었습니까?
