Externally Access Swarm Cluster Application Running in an Overlay Network

Hi everyone,

I’m running CentOS 7 Server with docker container “A” running over port 8443 in swarm overlay network. Want to provide external access to container over port 443 on the Centos 7 server. I’ve been working with firewall-cmd to see if I could forward port 443 to the [docker_gwbridge] ip address and port 8443. However, this doesn’t seem to be working. Any ideas on how to do this?

Thanks for your time.
