我怎麼才能刪除這31個iptables? grep 之後我應該添加什麼刪除命令,以便該iptables -S命令不顯示cali-iptables ?

刪除 calico-Iptables:

使用印花布政策並在腳本末尾添加以下行:

echo "Flush remaining calico iptables"
iptables-save | grep -i cali | iptables -F

echo "Delete remaining calico iptables"
iptables-save | grep -i cali | iptables -X

當您檢查時,這將刪除所有 calico iptablesiptables -S

筆記:僅在卸載 K3S 後執行此腳本。

刪除 calicoctl:

只需運行sudo rm $(which calicoctl)命令,它就會找到並刪除 calicoctl。
