获取Dockernetworking的主机名/ IP

我有这个：

# create network docker network create cdt-net 

我怎样才能得到这个Dockernetworking“cdt-net”的本地IP /主机名？

使用docker network inspect cdt-net ，我得到：

 [ { "Name": "cdt-net", "Id": "0c2bd01e2192a82fc5472e28b966b3692720ab902bfa99e8d4c6c825a13f8f11", "Created": "2017-05-09T23:33:52.632492853Z", "Scope": "local", "Driver": "bridge", "EnableIPv6": false, "IPAM": { "Driver": "default", "Options": {}, "Config": [ { "Subnet": "172.18.0.0/16", "Gateway": "172.18.0.1" } ] }, "Internal": false, "Attachable": false, "Containers": { "0f9dd64a2aafc95bdb9ea8cdbb2ab136d492426b421ee56780175d5710de5d32": { "Name": "cdt-selenium", "EndpointID": "ad5348e3fa445d241e0acec094c09f75c40ee8d0edcbe988f7ecbe43fb183c4a", "MacAddress": "02:42:ac:12:00:03", "IPv4Address": "172.18.0.3/16", "IPv6Address": "" }, "3c4d5394b42e444f313c3a8d2743e7564abfd65df66bf76cc22c676ca8e94861": { "Name": "cdt-mongo", "EndpointID": "5aa64d19e4eb429606b46826e616b391a27aebe794d8c945ef0af17ab34c3e57", "MacAddress": "02:42:ac:12:00:02", "IPv4Address": "172.18.0.2/16", "IPv6Address": "" }, "c9d0f5f1e5dbbe0be309ac0fa4b1620aca0b32e12b5f50027df541d6a519332b": { "Name": "cdt-server", "EndpointID": "7dbebd7e58c4c6579ebd0fcef54a86f22ae4696864fc783d3fcc9d953c949397", "MacAddress": "02:42:ac:12:00:04", "IPv4Address": "172.18.0.4/16", "IPv6Address": "" } }, "Options": {}, "Labels": {} } ] 

但是从这个angular度来看，我还不能确定如何从容器外部通过IP访问其中一个容器。 那可能吗？
