The solution around this is 2 fold:
Either use a front end load balancer that sends to the swarm nodes OR Configure the swarm nodes with like KeepaliveD to have a virtual IP address, and then point your DNS to that.
I'm personally using the second one for the past 4 years very happily.
When I'm interviewing people for any entry level, or even low level sysadmin positions, discussion of a homelab is always on my list of questions. I'm looking for not only the fact it exists, but also the passion you have talking about it. I can work on tech skills, but I can't teach passion.
Would be interested in this . We're using netbox but is this like a plugin
