Quota

The quota template represents a piece of data to check Quota for.

When writing the configuration, the value for the fields associated with this template can either be a literal or an expression. Please note that if the datatype of a field is not istio.mixer.adapter.model.v1beta1.Value, then the expression’s inferred type must match the datatype of the field.

Example config:

apiVersion: "config.istio.io/v1alpha2"
kind: quota
metadata:
  name: requestcount
  namespace: istio-system
spec:
  dimensions:
    source: source.labels["app"] | source.service | "unknown"
    sourceVersion: source.labels["version"] | "unknown"
    destination: destination.labels["app"] | destination.service | "unknown"
    destinationVersion: destination.labels["version"] | "unknown"

Value is used inside templates for fields that have dynamic types. The actual datatype of the field depends on the datatype of the expression used in the operator configuration.
