integration with firewalld for docker
Integration with firewalld
If you are running Docker with the iptables option set to true, and firewalld
is enabled on your system, Docker automatically creates a firewalld zone called docker, with target ACCEPT.
All network interfaces created by Docker (for example, docker0) are inserted into the docker zone.
Docker also creates a forwarding policy called docker-forwarding that allows forwarding from ANY zone to the docker zone.
