How to connect docker container via ssh?

I use the tutorial in this： https://docs.docker.com/examples/running_ssh_service/ and I have finish above step, and I use the docker ps to find the port ,and assume my port is 32769 when I input this command:

ssh [email protected] -p 32769

it just show me :

ssh root@localhost -p 32769 ssh: connect to host localhost port 32769: Connection refused

this is information about command that "docker ps":

bash-3.2$ docker ps
CONTAINER ID        IMAGE               COMMAND                CREATED             STATUS              PORTS                    NAMES
5e22e16a7742        liuxin/centos:ssh   "/bin/sh -c '/usr/sb   40 minutes ago      Up 40 minutes       0.0.0.0:32769->22/tcp    c_ssh_centos        
eaa412773bb2        registry            "docker-registry"      2 hours ago         Up 2 hours          0.0.0.0:5000->5000/tcp   registry

I use the Mac OS X and have opened remote login. I don't know how to make connect successed. Thanks

If ssh is telling you that it's trying to connect to localhost, then that's your problem. Docker doesn't run natively on the Mac. Instead, it runs in a VM which has its own IP address and that's what you need to connect to.

Assuming you're using docker-machine, you can do this:

$ docker-machine ls
NAME   ACTIVE   DRIVER         STATE     URL                          SWARM
dev    *        vmwarefusion   Running   tcp://192.168.201.162:2376

That shows that I have an active VM named "dev" as my Docker machine. Then I can run

ssh root@$(docker-machine ip dev) -p 32769

To ssh to the appropriate IP address.
