List Entry
The listentry template is designed to let you perform list check operations
with the list adapter.
Example config:
apiVersion: "config.istio.io/v1alpha2"

spec:
compiledTemplate: listentry

Template
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.
| Field | Type | Description | Required |
|---|---|---|---|
value | Value | Specifies the entry to verify in the list. This value can either be a string or an IP address. | No |
