List Entry

The listentry template is designed to let you perform list check operationswith the list adapter.

Example config:

apiVersion: "config.istio.io/v1alpha2"
kind: instance
metadata:
  name: appversion
  namespace: istio-system
spec:
  compiledTemplate: listentry
  params:
    value: source.labels["version"]

Template

The listentry template is used to verify the presence/absence of a stringwithin a list.

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