To specify the container ip when creating the container, create a new bridge network bridge1 by yourself, and create a subnet when creating the bridge1, you can specify the network as bridge1 and ip when creating the container.

When starting the docker container, using the default network does not support assigning a fixed IP, so create a custom network and set a fixed IP.

Docker is a commercially successful open source software that has been so popular since 2013 that it has become a benchmark for people to think of containers.

Compared with KVM, the most obvious feature of docker is that it starts quickly and takes up less resources.
