Lately I’m looking more and more into Python, with respect to automation implementations useful for network engineers. In the learning process I’ve used different materials, like the excellent video trainings Python Programming for Network Engineers from David Bombal which are available free on Youtube.
This training in particular relies on a Ubuntu Docker image in order to support Python learning following interaction with Cisco devices in GNS3. Everything is great, just that the image doesn’t contain all necessary tools (like Paramiko, Netmiko, Ansible…). As you can guess, whenever you close / open the Project in GNS3, all the installed packages installed in the Ubuntu Docker image are gone.
Since we’re talking automation, I got bored to install the necessary tools everytime I wanted to start a new project or I had to close GNS3 for some reason. I’ve tried to find a Docker image that suits my needs, but I couldn’t (please point me to one if you know it).
So, I’ve build a Docker image, based on Ubuntu 16.04, which contains the necessary tools to start learning Python programming oriented for network engineers:
- Net-tools (ifconfig..)
- IPutils (ping, arping, traceroute…)
- Python 2
- Python 3
- Paramiko (python ssh support)
- Netmiko (python ssh support)
- Ansible (automation)
The above list can be extended, but I would like to keep it to the minimum necessary (I want to keep the image size at decent level).
If you’re interested, please find the image at: https://hub.docker.com/r/yotis/ubuntu1604-pfne/, or you can download it:
$ docker pull yotis/ubuntu1604-pfne
I’ve tested the image for couple of days and it works fine. However if something doesn’t work as expected, please let me know and I’ll try to fix it.
For those using GNS3 is possible to import the image above directly into GNS3 using the PFNE Appliance.

Very nice! Me too would love to jump into network automation and thought your work would be perfect to start with but had a problem to complete pulling image in the GNS3. It kept saying “Waiting for http://127.0.0.1:3080” and kept trying forever. I’m using GNS3 2.1.9 for the try.
