Help with TIG stack from Nick Russo, error.

Juan Gerardo Hernandez — Fri, 03 Jun 2022 14:16:12 GMT

Hi Guys,

I am doing the lab from Nick Russo of Cisco MDT IOS XE and the TIG Stack from Pluralsight

https://app.pluralsight.com/player?course=provisioning-managing-networks-common-automation-tools&author=nick-russo&name=b3f9182e-5d99-4134-a408-148e0b9b1278&clip=0

I am configuring the routers using the netconf_mdt.py

https://github.com/nickrusso42518/pluralsight/tree/master/enauto1/m6/scripts

I can get to the part in which I can enable MDT subscriptions in the router.

end

but when it is time to install Nick's TIG stack I get this error.

This is what I am doing to set up the image,

I download the Nick Russo docker image and then issue a docker compose up.

https://github.com/nickrusso42518/tig-stack.git

#!/bin/bash
# Clone the tig-stack forked repository and change into directory
git clone https://github.com/nickrusso42518/tig-stack.git
cd tig-stack/

# Start the TIG stack in the background
docker-compose up --detach

# Check to see that TCP ports 42518, 3000, 8083, and 8086 are open
ss -tna

All the ports are fine:

but there is the error of above,

The TCP packets from my router are going to the my Ubunti Box, and even if the ports are listening, the machine does not respond.

can someone try to clone Nick's TIG image, and help me see why it is giving me those errors? and why telegraph is reseting the packeds it gets from the routers?

Thank you very much.

Juan

Hello @Juan Gerardo Hernandez,

I see Nick Russo forked that GitHub repo. Maybe you can raise an Issue with the originator:

https://github.com/matisku/tig-stack/issues

I never was able to make it work, I tried the matisku git, it didn't work... everything fails when I try to load the plugin of the Cisco Telemetry for 1000v.

If someone make it work, please share your discoveries.
