jq

jq is a command-line JSON processor. It works like sed for JSON data; you can use it to filter, parse, and transform structured data with the same ease that sed, awk, or grep let you do with raw text. Jq is available on GitHub at https://stedolan.github.io/jq/. The installation is very simple; it's just a single binary, available for Windows, macOS, and Linux. Just download it and copy it into the folder available on your system PATH to be able to run it from the shell or command-line.

Assuming we have all the tools installed before we start using kops, we will need to configure our AWS account first. This will be creating an administrative user and then, using the aws command-line tool, creating the user for running kops.
