example) and gateway • access to one or more DNS servers NOTE: If you're running systemd-resolved on Ubuntu, ensure that /etc/resolv.conf is linked to /run/systemd/resolve/resolv.conf, and not to /run/systemd/resolve/stub- including root SSH access • NTP (must be chrony) The cluster nodes in our examples are running Ubuntu. c. If you're planning on running with a DPDK data plane, prepare each cluster node that is running resolving. Check the domain name server configuration to make sure it's correct. For example, in a Ubuntu system running systemd resolved, check that /etc/resolv.conf is linked to /run/systemd/resolve/resolv
