SrednjaNivo 1Automatskadocker

Opis

Overlay network traffic between swarm nodes is unencrypted by default. On an active swarm node every overlay network must have the encrypted option; compliant when swarm mode is inactive.

Kako se proverava

Metod provere: Komanda ljuske

shell

st=$(docker info --format '{{.Swarm.LocalNodeState}}') || exit 1; [ "$st" = active ] || { echo compliant; exit 0; }; ns=$(docker network ls --filter driver=overlay --quiet) || exit 1; [ -z "$ns" ] && { echo compliant; exit 0; }; out=$(docker network inspect --format '{{.Name}} {{index .Options "encrypted"}}' $ns) || exit 1; bad=$(printf '%s\n' "$out" | awk 'NF<2 {print $1}'); [ -z "$bad" ] && echo compliant || printf 'unencrypted overlay: %s\n' $bad

Očekivani izlaz: compliant

Kako se ispravlja

Metod ispravke: Smernica ili zakrpa infrastrukture

Create overlay networks with --opt encrypted (docker network create -d overlay --opt encrypted <name>) and move services onto them.
