Simple NetDevOps CI with GitHub, Jenkins, pytest, and Webex
In this video, we define NetDevOps, what it can accomplish, and what bold, but worth it, changes it requires. Then, we will demonstrate a simple but effective NetDevOps CI pipeline that utilizes a GitHub repo and webhook, the Jenkins continuous integration tool, the pytest testing framework, and Webex for alerting. All of this technology is currently free.
The code used in this demo can be found on the Cisco Code Exchange at: http://cs.co/simple-netdevops-ci
We will build upon the work we did in the previous DevOps Shop, Intro to Ansible for Automation, where we used Ansible for automating the creation, updating, and deleting of ACLs on Cisco routers.
