I am trying to run nginx on docker swarm platform using default ingress network. I have created 3 replicas on 5 node cluster. I can access nginx from first 3 node where replica is running, but I can’t access nginx(curl) from other nodes where replica is not running, looks like docker iptables issue to me, but not able to figure it out what changes are needed. I can see ingress has opened the published 8080 port on all the nodes, but can’t access nginx via curl.
Further, I checked the firewalld logs and found below related log lines.
