Ensure a separate partition for containers has been created

SedangLevel 1Otomatisdocker

Deskripsi

Docker stores images and container data under its root directory (default /var/lib/docker); a separate partition stops containers filling the host root filesystem. The audit reads DockerRootDir from docker info and checks it is a mount point (mountpoint -q).

Cara pemeriksaan

Metode audit: Perintah shell

shell

d=$(docker info --format '{{ .DockerRootDir }}') || exit 1; [ -n "$d" ] || exit 1; if mountpoint -q -- "$d"; then echo compliant; else echo "not a separate mount: $d"; fi

Output yang diharapkan: compliant

Cara perbaikan

Metode perbaikan: Panduan atau patch infrastruktur

For new installations, you should create a separate partition for the /var/lib/docker mount point. For systems which have already been installed, you should use the Logical Volume Manager (LVM) within Linux to create a new partition.
