Backend Protocol

使用 backend-protocol 注解可以配置 Nginx 使用哪种协议转发给 backend service

有效值: HTTP, HTTPS, GRPC, GRPCS, AJP and FCGI

Nginx 默认使用 HTTP。

Example:

nginx.ingress.kubernetes.io/backend-protocol: "HTTPS"

yaml example

因为 k8s-dashboard 默认使用 https 协议，所以需要使用

nginx.ingress.kubernetes.io/backend-protocol: "HTTPS"
