這裡是 OpenSUSE 15.3 用戶。我打破了 docker 在 iptables 上創建的預設規則，並且不知道如何修復它。我已經嘗試重新安裝 docker 了。發生的情況如下：
vm-dev:~ # systemctl start docker
vm-dev:~ # tail /var/log/messages | grep firewalld
2022-04-21T00:53:25.607359-04:00 vm-dev firewalld[19494]: WARNING: COMMAND_FAILED: '/usr/sbin/iptables -w10 -t nat -D OUTPUT -m addrtype --dst-type LOCAL -j DOCKER' failed: iptables: No chain/target/match by that name.

然後，每次我這樣做firewall-cmd --reload，我都會得到：
2022-04-21T00:53:35.536326-04:00 vm-dev firewalld[19494]: WARNING: COMMAND_FAILED: '/usr/sbin/iptables -w10 -D FORWARD -i docker0 -o docker0 -j DROP' failed: iptables: Bad rule (does a matching rule exist in that chain?).
以下是評論中的一些附加資訊：

我目前沒有正在運行的 docker。事實上，我卸載了docker，/var/lib/docker完全刪除，然後重新安裝，錯誤仍然存在。此docker0介面位於docker中的區域firewalld。我沒看到裡面有什麼特別的。我需要做什麼來修復這些錯誤？任何幫助，將不勝感激。
