기본적으로 다운로드되는 Ubuntu Docker 이미지를 사용합니다. 나는 원해요해당 컨테이너에서 네트워크 인터페이스와 IP 주소를 찾습니다., 그래서 포함된 패키지를 설치하고 싶은데 ifconfig왜 실패합니까? 감사해요.

각docker run이 명령은 별도의 컨테이너를 실행하므로 명령의 효과가 다음 컨테이너에 지속되지 않습니다 docker run.
새 컨테이너에서 프로세스를 실행합니다.
docker run자체 파일 시스템, 자체 네트워크 및 자체 독립 프로세스 트리를 사용하여 프로세스를 시작합니다.
모든 명령을 결합해야 합니다.
docker run -it ubuntu /bin/sh -c 'apt update && apt upgrade -y && apt install -y net-tools'
여기에서 실행하려는 명령을 추가하세요 net-tools.
하나 를 쓸 가치 가 있을 수도 있습니다 Dockerfile.
