Prereqs

Ensure that the following tools are installed for this exercise (each of the keywords below contains a link to the installation web page for the referenced product):

• Docker Desktop - The easiest way to get going with Docker is to install Docker Desktop. Docker is a container toolset and runtime used to build KubeFox Component OCI images and run a local Kubernetes Cluster via kind. Click the link corresponding to the OS you wish you use.
  • MacOS - Install Docker Desktop on Mac.
  • Windows - Install Docker Desktop on Windows.
  • Linux - Install Docker Desktop on Linux.
• Fox - A CLI for communicating with the KubeFox Platform.
• Git - A distributed version control system. If this is the first time you're installing git, go through the steps to ensure that your identity is established (see "Your Identity" on the next page).
• Helm - Package manager for Kubernetes used to install the KubeFox Operator on Kubernetes.
• kind - kind is Kuberentes in Docker. kind is a tool for running local Kubernetes Clusters using Docker container "nodes", hence Docker must be running before you use kind to create your Kubernetes cluster.
• Kubectl - CLI for communicating with a Kubernetes Cluster's control plane, using the Kubernetes API.

Here are a few optional but recommended tools:

• Go - A programming language. The hello-world example App is written in Go, but Fox is able to compile it even without Go installed.
• VS Code - A lightweight but powerful source code editor. Helpful if you want to explore the hello-world app.
• Azure CLI - CLI for communicating with the Azure control plane.
• k9s - A terminal based UI to interact with your Kubernetes clusters. You can use native kubectl commands to accomplish the same things, but k9s is a nice convenience and we use it here. By the way, the k9s homepage is probably the cleverest of any company in the k8s space, succeeding in that endeavor at many levels.
