Overview ¶
Package template implements the JSONPath template format used by kubectl.
See https://kubernetes.io/docs/reference/kubectl/jsonpath/ for more information.
In some cases, it deviates slightly from the syntax accepted by kubectl's JSONPath expressions:
- The use of \ to escape the next character in identifiers is not supported.
- The use of @['x.y'] (equivalent to @.x.y) inside brackets is not supported, as it could conflict with an actual key in a JSON object.
