telnet到运行zookeeper容器

我正在运行zookeeper作为一个容器，并使用zookeeper作为图像。

dockerizer@docker1:~$ docker run --name some-zookeeper --restart always -d zookeeper 3a06702276a4a0cb80fb80d66c380918e12901e1a03106b93a4e1f01d1280fd4 dockerizer@docker1:~$ docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 3a06702276a4 zookeeper "/docker-entrypoin..." 8 minutes ago Up 8 minutes 2181/tcp, 2888/tcp, 3888/tcp some-zookeeper 

正如你所看到的，容器正在运行3个暴露的端口。
该容器具有以下IP地址：

 "Containers": { "3a06702276a4a0cb80fb80d66c380918e12901e1a03106b93a4e1f01d1280fd4": { "Name": "some-zookeeper", "EndpointID": "ff7eeccb2d31e7aeb8c0784fcd972822f74fadaac4bb6e17177685a9bddbe0f1", "MacAddress": "02:42:ac:11:00:02", "IPv4Address": "172.17.0.2/16", "IPv6Address": "" } 

然后我尝试telnet它如下：

 dockerizer@docker1:~$ telnet 172.17.0.2 2181 Trying 172.17.0.2... Connected to 172.17.0.2. Escape character is '^]'. 

正如你可以，动物园pipe理员容器没有回应。 我究竟做错了什么？
