Ensure that a user for the container has been created

SedangLevel 1Otomatisdocker

Deskripsi

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.

Cara pemeriksaan

Metode audit: Perintah shell

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"

Output yang diharapkan: compliant

Cara perbaikan

Metode perbaikan: Panduan atau patch infrastruktur

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