commands operate as follows: See if the host has a br0 bridge and it does not exist; Add a NIC named Eth1 to the test01 and configure the IP172.18.18.36/24; If there is already a default route in test01, delete it and set 172.18.18.1 as the default route L Connect the test01 container to the br0 on the previously created bridge; This process is similar to the previous process of using IP command configuration, pipework is actually code written in Shell.Pipework in fact
