Run a node with the image you created, there is a problem with the connection

Create an image with the container ubuntublock, where Daocloud.io/ubuntu is the mirror used when making the container

Docker commit Ubuntublock   Daocloud.io/ubuntu/ubuntublock

Then run two containers with our own image, Node1, Node2

Docker run-it--name node1 daocloud.io/ubuntu/ubuntublock/bin/bash
Docker run-it--name node2 daocloud.io/ubuntu/u Buntublock/bin/bash

When created, you can do it yourself.
