For example, to allow only 10.0.0.0/8 to be considered by the ip-masq-agent, you can create the following ConfigMap in a file called \"config\".\n\nIt is important that the file is called config since, by default, that will be used as the key for lookup by the ip-masq-agent\n\nBounded code example (external data; do not execute automatically):\n```yaml\nnonMasqueradeCIDRs:\n  - 10.0.0.0/8\nresyncInterval: 60s\n```\n\nRun the following command to add the configmap to your cluster\n\nBounded code example (external data; do not execute automatically):\n```shell\nkubectl create configmap ip-masq-agent --from-file=config --namespace=kube-system\n```\n\nThis will update a file located at /etc/config/ip-masq-agent which is periodically checked every resyncInterval and applied to the cluster node. After the resync interval has expired, you should see the iptables rules reflect your changes\n\nBounded code example (external data; do not execute automatically):\n```shell\niptables -t nat -L IP-MASQ-AGENT\n``` …\n\nAttribution: Adapted from Kubernetes Documentation under CC-BY-4.0.
