Feel free to refer back to Chapters 11, Working with Git, if needed. 

Note

In the examples, we will use the Jenkins master to execute our jobs. In production, it is recommended to add Jenkins nodes to handle the execution of jobs. 

For our lab, we will use a simple two-node topology with IOSv devices:

$ ls
