Ingress-nginx: Feature Request: support gRPC over plaintext (non-TLS)

Created on 15 Mar 2019 · 11Comments · Source: kubernetes/ingress-nginx

Since NGINX does support gRPC over plaintext (non-TLS), and why ingress-nginx does not support it? Ingress-nginx can listen on a new http2 port, and proxy grpc requests to grpc backend services.

That said, we could add a new annotation where we enable http2 in the listen section of port 80 but that means all the ingresses/paths for that server will not be available for HTTP/1.x clients

NGINX does not support HTTP/1.x and HTTP/2 at the same time on a cleartext (non-TLS) port.
Because of that we cannot support gRPC over port 80. ~~Closing.~~

I know that NGINX does not support HTTP/1.x and HTTP/2 at the same time on a cleartext (non-TLS) port, and it would be great if we can listen on a new port (e.g. 8080).

Sorry but no, Ingress is about port 80 and 443. If we add this feature it will be as described in the previous comment.

@aledbf This would be a good compromise. We'd like to be able to use http2 non-tls ingress and have no need for 1.1.

Has there been any development here? We would also like to support both GRPC (HTTP/2) and HTTP/1.1 plaintext on the same port.
