How to make changes istio-ingressgateway when using GKE Istio Addon?

Question

I have google cloud gke cluster installed with istio via addon. I need to change the istio-ingressgateway to NodePort. the problem is that the addon manager is always reverting my changes. Is there a way to disable it from reverting to the original ingressgateway?

Thanks

You can't make any changes to the istio pods when using the istio on GKE addon. All of the resources in the istio-system namespace are managed and include the label "addonmanager.kubernetes.io/mode: Reconcile" which causes any changes you do to be reverted.

The general consensus is that the istio addon is meant more to be a demo, advanced users should install istio manually and use the unamanaged version

Thanks. I know, but isn't there a way to install addon with EnsureExists instead of reconcile? – Uri Aflalo Jul 04 '19 at 20:39
yes, they could do it, but that would have to be modified by the istio team at Google. Your best bet would be to file a feature request through the Google Issue Tracker – Patrick W Jul 08 '19 at 16:40
Got it. Thanks a lot! – Uri Aflalo Jul 09 '19 at 17:05
