Create a netplan configuration file under /etc/netplan/50-cloud-init.yml.\n\nThe following example configuration file is a starting point. Adjust it to match the interfaces you want to un-manage. Incorrect configuration can lead to network connectivity issues.\n\nBounded code example (external data; do not execute automatically):\n```yamltitleetcnetplan50-cl\n   network:\n     ethernets:\n       all:\n         dhcp4: true\n         dhcp6: true\n         match:\n           # edit this filter to match whatever makes sense for your system\n           name: en*\n     renderer: networkd\n     version: 2\n```\n\nApply the new Netplan configuration.\n\nBounded code example (external data; do not execute automatically):\n```console\n   $ sudo netplan apply\n```\n\nRestart the Docker daemon\n\nBounded code example (external data; do not execute automatically):\n```console\n   $ sudo systemctl restart docker\n```\n\nVerify that the Docker interfaces have the unmanaged state.\n\nBounded code example (external data; do not execute automatically):\n```console\n   $ networkctl\n```\n\nAttribution: Adapted from Docker Documentation under Apache-2.0.
