Chapter 3, Setting Up a Test Environment

1. While the Prometheus stack can be deployed in almost every mainstream operating system, and thus, it will most certainly run in your desktop environment, it is more reproducible to use a Vagrant-based test environment for simulating machine deployments, and minikube to do the same for Kubernetes-based production environments.
2. The defaults.sh file located in the utils directory allows the software versions to be changed for the virtual machine-based examples.
3. The default subnet is 192.168.42.0/24 in all virtual machine-based examples.
4. The steps to get a Prometheus instance up and running are as follows:
   1. Ensure that software versions match the ones recommended.
   2. Clone the code repository provided.
   3. Move into the chapter directory.
   4. Run vagrant up.
   5. When finished, run vagrant destroy -f.
