Ensure Docker is allowed to make changes to iptables

中级别 1自动化docker

说明

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.

检查方式

审计方法: Shell 命令

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

预期输出: compliant

修复方式

修复方法: 操作指南或基础设施补丁

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