I have a docker swarm with three manager nodes on which I deployed the jordan/icinga2 image using the ingress network. I can reach the icingaweb site well but the other direction does not work, i.e. I cannot reach anything in the outer world from within the container. When I ping an external computer, this server receives the ping packages with a source address of 172.19.0.3.
Any advice what I have forgotten?
The docker create command I use is
docker service create --name icinga2 -p 5665:5665 -p 443:443 -p 80:80 \ [ommitting several mounts] --hostname "icinga.example.com" \ --dns 192.168.56.25 \ jordan/icinga2:latest
Many thanks, Cord
