After docker installation inside openstack instance and creation of conatiners and deployment of a system inside the container.

I need to manage docker containers resides on the openstack instance. But i don't know how can process that.

I installed docker library and i tried to access the instance using python API using this code:

import paramiko, sys, getpass

hostname = '192.168.x.x'

username = 'ubuntu'

password = 'password'

ssh = paramiko.SSHClient()

ssh.connect(hostname=hostname, username=username, password=password)

I failed to connect to the instance

2018-12-13 04:49:59 -0600 commented answer Openstack private cloud

my nodes are not connected using a physical switch. I think they are connected with virtual switches.

If i am using a switch, should i change anything in the OpenStack configuration (e.g., mangement interface, provider interface, etc) ?
