첫 번째 Docker 실행에서는 파일이 누락되었지만 두 번째 실행에서는 사용할 수 있는 이유는 무엇입니까?

첫 번째 Docker 실행에서는 파일이 누락되었지만 두 번째 실행에서는 사용할 수 있는 이유는 무엇입니까?

이것은 매우 이상한 상황입니다. Travis CI에서 알파인 기반 도커 컨테이너를 실행합니다. 그런 다음 다음과 같이 실행합니다 ls.

docker exec $CONTAINER_NAME ls -la specific/directory
docker exec $CONTAINER_NAME ls -la specific/directory

첫 번째 명령은 파일 목록을 표시하지만 있어야 할 일부 파일이 누락되었습니다(이미지 빌드의 일부이며 다른 플랫폼에서 조사할 때 이미지 내부에 존재함).

출력 예: 다음의 숫자를 기록해 두십시오.file_#

.또한 첫 번째 명령이 및 디렉토리를 표시하지 않는 것으로 나타났습니다 ...

왜 이런 일이 발생합니까? 그리고 그것을 피하는 방법은 무엇입니까?

참고: 이는 그냥 발생하는 것이 아닙니다 ls. 애플리케이션 코드가 처음으로 파일 목록을 표시하려고 하면 축소된 목록이 표시됩니다. 하지만 다시 나열하면 전체 목록이 표시됩니다!
