handle HTTP and gRPC request into Envoy

Question

Need to convert HTTP request into gRPC using Envoy. Backend micro service is working fine and it will support gRPC, but doesn't handle Http, so I need to convert request to grpc using envoy.

So the benefit is, both http and gRPC can handle together. Is it possible with Envoy, if yes, how can I do the configuration in Envoy.

Why do you think you need to use envoy to convert HTTP to gRPC? I don't think to add Envoy complexity to you app is the best option. Is Envoy already part of your stack? You can always create a simple HTTP endpoint which will get the HTTP request and call a gRPC method. It is pretty simple. Here an example in Golang github.com/apssouza22/protobuf-api-management/blob/master/… Also, consider looking at the github.com/grpc-ecosystem/grpc-gateway — Alexsandro Souza
@AlexsandroSouza Application is running with micro framwork with 20 modules , as per your concern we need to call direclty to all module , also micro api have the ability to accept http requests and forward it to our services.. same only envoy/nginx does, but envoy/nginx have better ability to handle the request performance. I have tried both nginx and envoy as a gateway , but betting CORS issue — shufilkhan

You can see how to work with gRPC over HTTP using Envoy here: https://github.com/grpc/grpc-web. If you just need Envoy config, see one example here: https://github.com/grpc/grpc-web/blob/master/net/grpc/gateway/examples/echo/envoy.yaml
