The wildcard / egress gateway config described at https://istio.io/docs/tasks/traffic-management/egress/wildcard-egress-hosts/#wildcard-configuration-for-arbitrary-domains only talks about egress using a gateway to https://some-host:443 . The config for this use case is fairly complex (I got it to work though).
What about if we need to expand the use case to include for example:
- Applications hosted at other ports eg https://another-host:1443
- Non-http ports eg JMS , AMQP etc … hosted outside the cluster
What would need to be added to the config?
I’m trying to decide if it’s worth pursuing an egress gateway w/ wildcard support for the expanded use case or just use the ALLOW_ANY egress policy
