Description
Describe the feature request
Having port range or port wildcard in configurations and rules.
Context:
-
Configure external service (Apache ActiceMQ server in particular) for Istio Service Mesh
-
External services like Apache ActiceMQ, they have a few standards ports but then also use a random port to communicate with established clients (via JMS etc.). So to whitelist them, it would be useful that port range/wildcard can be defined like the below.
For example, defining a ServiceEntry
apiVersion: networking.istio.io/v1alpha3
kind: ServiceEntry
metadata:
name: "activemq"
spec:
hosts:
- activemq.external
location: MESH_EXTERNAL
resolution: DNS
ports:
- name: "all-ports-activemq"
number: *
protocol: TCP
