宿主机能够ping通荣容器吗 my_nginx_bridge: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN group default qlen 1000 b22b9@if29: <BROADCAST,MULTICAST> mtu 1500 qdisc noop master my_nginx_bridge state DOWN group default qlen 1000 我这里启动之后ping不通，ubuntu:20.4

网络能ping通了，但是端口映射不知道是否通了，无法访问nginx，这个有什么办法检查端口映射是否正确吗

iptables -t nat --list Chain PREROUTING (policy ACCEPT) target prot opt source destination
DOCKER all -- anywhere anywhere ADDRTYPE match dst-type LOCAL DNAT tcp -- anywhere anywhere tcp dpt:20020 to:172.18.0.2:80

执行一下 ufw disable或者ufw enable就好了
