建立HOST主機橋接網路

brctl addbr br0 brctl addif br0 enp0s3 ifconfig enp0s3 0.0.0.0 dhclient br0

設定固定IP的 Bridge 網路

sudo cp /etc/netplan/50-cloud-init.yaml /etc/netplan/50-cloud-init.yamlbak

sudo vi /etc/netplan/50-cloud-init.yaml

network:
  version: 2
  renderer: networkd

    enp0s3:
      dhcp4: false 
      dhcp6: false

接著我們可以把HOST機同往段的網路設定，使用pipework 加入 container
