Ensure Docker is allowed to make changes to iptables

SedangLevel 1Otomatisdocker

Deskripsi

Docker must manage iptables so that container networking rules stay consistent with the daemon configuration. Compliant unless iptables is explicitly set to false. The audit reads the running dockerd command line (ps) together with /etc/docker/daemon.json.

Cara pemeriksaan

Metode audit: Perintah shell

shell

args=$(ps -eo args 2>/dev/null) || exit 1; s=$(printf '%s\n' "$args" | grep '[d]ockerd'; cat /etc/docker/daemon.json 2>/dev/null); printf '%s\n' "$s" | grep -Eq -e '--iptables[= ]+false|"iptables"[[:space:]]*:[[:space:]]*false' && echo noncompliant || echo compliant

Output yang diharapkan: compliant

Cara perbaikan

Metode perbaikan: Panduan atau patch infrastruktur

Remove "iptables": false from /etc/docker/daemon.json and --iptables=false from the dockerd start-up flags, then restart the Docker daemon.
