Preparing a lab environment for Kubernetes testing
In an organization, planning a roll-out of an entire Kubernetes cluster can be fairly involved—you may have to purchase hardware and also analyze your existing environment and understand how containerization will fit in. It's possible that some applications you want to run aren't a good fit for containers; some don't support running in a container at all. Assuming you've already checked the documentation for the applications you are wanting to run in containers and came to the conclusion that such a technology is supported, the next step is procuring the hardware (if you don't already have a place to run it) and then setting up the cluster.
Specific to us in this book, we don't need to contact a server vendor and submit a purchase order to simply test out the technology. If you are actually involved with the rollout of container orchestration at your organization, then it's a fun project...
