I’m currently experimenting with my raspberry pi cluster and HA. What happens when I point the DNS A record of mycoolwebsite.com to node1 (192.168.1.100). When all of the nodes in the picture are running the ingress network from docker swarm will handle the request to the node with the container on it. But what happens if node1 goes down. The DNS record no longer works because nothing is listening on that ip.
I couldn’t find good documentation on this issue. Or is it an assumption that people running a docker swarm have a reverse proxy like nginx, HAProxy or traefik? I think treafik looked really cool, but that would run on a manager node, when that manager node goes offline. Your still left with nothing?
