192.168.56.11 上面
docker network create -d overlay --subnet 192.168.1.0/24 ov_net1 #192.168.56.12 上面默认就有了 不用创建了

192.168.56.11测试
docker run -it --rm --net=ov_net1 busybox
192.168.56.12测试
docker run -it --rm --net=ov_net1 busybox
查看两个容器的IP地址互相ping下 可以ping通
docker run -it --rm --net=ov_net1 --ip=192.168.1.10 busybox #指定IP地址
