创建容器指定网络

docker run -id --name=c_centos1 --network=test-network --network-alias=centos1 centos:8
docker run -id --name=c_centos2 --network=test-network --network-alias=centos2 centos:8
docker run -id --name=c_centos3 --network=test-network --network-alias=centos3 centos:8

进入容器 ping 网络

docker exec -it c_centos1 bash
docker exec -it c_centos2 bash
docker exec -it c_centos3 bash

ping

ping c_centos1
ping c_centos2
ping c_centos3
