JSONpath

JSONpath is an expression language used to filter JSON Data. It is also used within Kubernetes (kubectl) to filter the output when using the “-o=jsonpath” option.

To get some real practice, I highly suggest following the free course by KodeKloud. Most of the information listed here is lifted from the course.

This is a quick primer on some JSON terms.

{
  "danse_macabre": {
    "manufacturer": "Intamin",
    "type": "Dynamic Motion Stage"
  }
}

To get for example the type of danse_macabre here, you would use the jsonpath $.danse_macabre.type.
