--- Comment #17 from Marek Goldmann  ---
Please use this scratch build:

https://koji.fedoraproject.org/koji/taskinfo?taskID=6231502

I've added this to the docker.service:

[Unit]
...
Requires=firewalld.service
After=firewalld.service

To make sure the iptables rules are executed after the firewalld is actually
running (if available) to prevent seeing network connectivity issues after
boot.
