Amounts to the same thing but no. Promox servers with two bridged interfaces. One interface has a public IP, the other a 10.0.10.0/24 etc. Multiple baremetal servers are connected by wireguard and have access to each other's private subnets. Like one other might be the 10.0.20.0/24. Setup the routes and good to go. Firewall to taste. My private LAN is all open.
This is not just for docker. There are other vms and lxc containers too.
