@zjj2wry please use the existing approach to parse annotations https://github.com/kubernetes/ingress/tree/master/core/pkg/ingress/annotations

[aledbf]

Also change the name to something like proxy-stream-timeout

I set it up like this and restarted all the pods, and found that it hasn't changed. It's still the default 600s.

try use ingress.kubernetes.io/proxy-stream-timeout.

Is it solved?
annotations:
ingress.kubernetes.io/proxyTimeout: 1h in tcp service config map but it's still the default 600s
