You're performing an operation over default zone ('public'),
but your connections/interfaces are in zone 'docker' (see --get-active-zones)
You most likely need to use --zone=docker option.

public
  target: default
  icmp-block-inversion: no

解决方案：

systemctl start firewalld
systemctl enable firewalld
