Set proxy-buffer-size on Istio Ingressgateway just like on Nginx Ingress Gateway

Hi All,

I am currently migrating nginx ingress gateway annotations to the istio ingress.

I have not found on the documentation or Google, how to set the annotation nginx.ingress.kubernetes.io/proxy-buffer-size on the Istio ingress gateway.

Does anyone have an idea how to do this?

Best regards,
rforberger

I’m also interested to know, how I set the

nginx.ingress.kubernetes.io/proxy-read-timeout
and
nginx.ingress.kubernetes.io/proxy-send-timeout
and the
nginx.ingress.kubernetes.io/proxy-body-size

annotations on the Istio ingress gateway.
