The listentry
template is designed to let you perform list check operations
with 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"]
The listentry
template is used to verify the presence/absence of a string
within a list.
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.policy.v1beta1.Value, then the expression’s inferred type must match the datatype of the field.
