Hi @LuBingtan. Thanks for your PR.

I'm waiting for a kubernetes-sigs member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

This looks a little tricky. Is the k8s_external plugin enabled by default? or is there any chance the actual external_ip field will be needed in vc (I know we did not upward synchronization it right now) ?

The bottom line is that if we want to play the trick in the syncer, we need a feature switch for sure. @christopherhein, will this help in your case?

As far as I know, the k8s_external plugin is not enabled by default.

As for the question whether the actual external_ip field is needed in vc. According this doc (https://kubernetes.io/docs/concepts/services-networking/service/#external-ips), this field is used for exposing the service on a specific node. That means it is usually set by users on purpose. We can add an if and leave this field unchanged in this case.

And I agree with you that we need a feature switch.

christopherhein commented 1 year ago

Agree about the feature switch.

Does this work with DualStacked services too? For us, we're going the route of actually making the services routable to the tenant. This might may be useful for some folks though, the patch is kind of messy.

Already add a feature gate. PTAL 😄

As for dual-stack services, I'll give it a try and see if this works.
