I installed docker on centos 7.9 cloudimage and docker0 rule is missing on iptables

I used a standard centos 7.9 cloudimage to run a group of docker containers. But I do miss the docker 0 rule
-A INPUT -i docker0 -m comment --comment “Docker0 interface” -j ACCEPT
which was created on 7.7 automatically

Is this done by intention or a failure of the installation dependend on the centOs base ?
