You know the drill. We'll move into the directory with the vfarcic/k8s-specs (https://github.com/vfarcic/k8s-specs) repository, we'll pull the latest version of the code just in case I pushed something recently, and we'll create a new cluster unless you already have one at hand.
All the commands from this chapter are available in the 07-logging.sh (https://gist.github.com/vfarcic/74774240545e638b6cf0e01460894f34) Gist.
1 cd k8s-specs 2
