When dealing with Kubernetes, you will inevitably have to deal with config and data that is in JSON format. jq is a cool tool to handle this, but while the man page is complete, it is also very dry. A nice tutorial can be found at The Programming Historian, which uses some real world use cases. My personal use case is Converting JSON to CSV , and the inverse of that . There also is a mildly interesting FAQ . Learning jq takes about one quiet afternoon of time.
