Ensure that a user for the container has been created

보통레벨 1자동docker

설명

Containers should run as a non-root user defined in the image (USER) or at run time (--user). Flags containers whose configured user (Config.User) is empty, root or 0; processes that start as root and drop privileges themselves are reported too and need review. The audit inspects every running container (docker ps -q) and prints the offending names; a host with no running containers is compliant.

점검 방법

감사 방식: 셸 명령

shell

ids=$(docker ps -q) || exit 1; [ -z "$ids" ] && { echo compliant; exit 0; }; out=$(docker inspect --format '{{.Name}} [{{.Config.User}}]' $ids) || exit 1; bad=$(printf '%s\n' "$out" | awk '$2=="[]" || $2 ~ /^\[(root|0)(:.*)?\]$/ {print $1}'); [ -z "$bad" ] && echo compliant || printf '%s\n' "$bad"

예상 출력: compliant

조치 방법

조치 방식: 가이드 또는 인프라 패치

Add a USER instruction to the Dockerfile (RUN useradd -r app && ... USER app) or run the container with --user <uid>:<gid>.
