Opis

NetworkMode=host gives the container full access to host network interfaces and services bound to localhost. The audit inspects every running container (docker ps -q) and prints the offending names; a host with no running containers is compliant.

Kako se proverava

Metod provere: Komanda ljuske

shell

ids=$(docker ps -q) || exit 1; [ -z "$ids" ] && { echo compliant; exit 0; }; out=$(docker inspect --format '{{.Name}} {{.HostConfig.NetworkMode}}' $ids) || exit 1; bad=$(printf '%s\n' "$out" | awk '$2=="host"{print $1}'); [ -z "$bad" ] && echo compliant || printf '%s\n' "$bad"

Očekivani izlaz: compliant

Kako se ispravlja

Metod ispravke: Smernica ili zakrpa infrastrukture

Redeploy without --network=host (compose: remove 'network_mode: host'); publish only the required ports.
