容器之间通信方式
1、–link
2、查看现有网络
docker network ls
居于现有网络创建容器
docker run -d -P --name t1 --net bridge busybox
docker run -d -P --name t2 --net bridge busybox
然后t1就可以ping t2 了。但是需要使用 t2 Ip 。使用别名不通
3、自己创建网络
docker network create mynet
然后运行容器
docker run -d -P --name t3 --net mynet busybox
docker run -d -P --name t4 --net mynet busybox
这样就可以使用别名ping 通
docker exec -it t3 tping t4
运行结果如下：
