Ensure that the memory usage for containers is limited

SrednjaNivo 1Automatskadocker

Opis

Without a memory limit a single container can exhaust host memory (denial of service). Flags containers with HostConfig.Memory = 0. 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.Memory}}' $ids) || exit 1; bad=$(printf '%s\n' "$out" | awk '$2=="0"{print $1}'); [ -z "$bad" ] && echo compliant || printf '%s\n' "$bad"

Očekivani izlaz: compliant

Kako se ispravlja

Metod ispravke: Smernica ili zakrpa infrastrukture

Redeploy with a memory limit (docker run --memory=512m ...; compose: deploy.resources.limits.memory / mem_limit).
