Firewalld for Docker Containers
https://github.com/aceberg/my-dockerfiles/tree/main/firewalld

Create firewalld container

IMPORTANT: --cap-add=NET_ADMIN needed for this to work!

docker run --name firewalld \
    -v $DOCKERDATAPATH/firewalld:/etc/firewalld \
    --cap-add=NET_ADMIN \
aceberg/firewalld

Firewall configuration will be saved in /etc/firewalld

Create any client container

docker run --name ubuntu        \
--network='container:firewalld'  \
ubuntu

Now this ubuntu container will be using network through firewalld
