PATCH API don't work on Google Cloud Run instance

Asked 2021-Sep-16 at 11:08

I have cloud run services hosting GO OSB application implementing gRpc but exposing the http REST api's via grpc-gateway which uses cloud sql (mysql) as a DB. All the CRUD API's are responding fine except the PATCH one.

It's throwing the below error with http response code 503:

This is fixed now !

Facing the due to handling of multiple protocols on the same port and one of the protocol matchers was causing the issue with PATCH API by returning Empty reply from server. So, done changes to the matchers and it worked.

RCA : Cmux HTTP1Fast Matcher only matches the methods in the HTTP request. This matcher is very optimistic: if it returns true, it does not mean that the request is a valid HTTP response. A correct but slower HTTP1 matcher, used "HTTP1" instead which scan the whole request up-to 4096 bytes but its bit slow.

QUESTION

Handle REST requests in golang GRPC server

Asked 2021-Apr-03 at 14:05

Is it possible for a GRPC server written in golang to also handle REST requests?

I've found the grpc-gateway which enables turning an existing proto schema into a rest endpoint but I don't think that suits my needs.

I've written a GRPC server but I need to also serve webhook requests from an external service (like Github or Stripe). I'm thinking of writing a second REST based server to accept these webhooks (and possibly translate/forward them to the GRPC server) but that seems like a code-smell.

Ideally, I'd like for my GRPC server to also be able to, for example, handle REST requests at an endpoint like /webhook or /event but I'm not sure if that's possible and if it is how to configure it.

How to connect to the gRPC service inside k8s cluster from outside gRPC client

Asked 2021-Mar-21 at 07:12

I have a gRPC server running on port 9000 with gRPC-gateway running on port 9080. I can make request to my service with postman using the following link: ```http://cluster1.example.com/api/v1/namespaces/default/services/my-service:9080/proxy

How can I connect to my service from gRPC client (on my local machine, which is outside of the cluster) using grpc.Dial()?

Example:

ANSWER

Answered 2021-Mar-19 at 23:52

You should be able to connect to services in your k8s cluster from local with port forwarding:

kubectl port-forward --context -n svc/my-service 9000:9000

And then you just pass the gRPC target into Dial with localhost and no scheme:

GRPC-gateway default healthCheck support

Asked 2021-Mar-16 at 10:06

I'm using gRPC-gateway that works perfectly fine. But I need to have HealthCheck. I enabled DefaultHealthCheck and it works perfectly. TO make it possible, to check state over HTTP1.1 I found this solution https://github.com/salrashid123/grpc_health_proxy. ANd it works as well. But it's not the best solution to maintain 2 "gateways" + server by it self. So, my qestion is - if there is possible to enable defaultHealthCheck proxying in gRPC gateway? BEcause I don't understand how to implement this solution from docs https://grpc-ecosystem.github.io/grpc-gateway/docs/operations/health_check/

...

ANSWER

Answered 2021-Mar-16 at 10:06

So, the easiest way is to implement HealthCheck protocol procedures that basically return healthy state(200) and regenerate stubs with it, also gateway should be generated with it. Works perfectly fine for ALB AWS.

protoc generated grpc files and gateway files end up in different paths?

Asked 2021-Feb-15 at 19:33

I'm a bit baffled about this. File structure:

...

ANSWER

Answered 2021-Feb-15 at 19:33

As per the comments you were using the module option (--go_opt=module=${module} & --go-grpc_opt=module=${module}) when generating the protobuf & gRPC files. The option you were using when generating the gateway files (--grpc-gateway_opt paths=source_relative) uses a different algorithm to work out where to store the files; the fix being to use the module option - --grpc-gateway_opt module=${module}.

Here is what the docs have to say about the three options (these specific options are for protobuf generation; the other generators have the same functionality but replace go_ with go-grpc_/grpc-gateway_):

By default, the output file is placed in a directory named after the Go package's import path. For example, a file protos/foo.proto with the above go_package option results in a file named example.com/foo/bar/foo.pb.go.
If the --go_opt=module=$PREFIX flag is given to protoc, the specified directory prefix is removed from the output filename. For example, a file protos/foo.proto with the go_package option "example.com/foo/bar" and the flag --go_opt=module=example.com/foo results in a file named bar/foo.pb.go.
If the --go_opt=paths=source_relative flag is given to protoc, the output file is placed in the same relative directory as the input file. For example, the file protos/foo.proto results in a file named protos/foo.pb.go.

gRPC GO Single Generic Service Handler

Asked 2021-Jan-13 at 09:29

I have used protoreflect to write http-to-gRPC-gateway. But I don't see any easy option to do the reverse - gRPC-to-HTTP-gateway. One of the idea is to expose GRPC to outside but use a custom gateway to invoke internal microservices via MessageQ to avoid loadbalancing, discovery service and may be convert GRPC streaming durable or use reflection to invoke method instead of using generated server stub

Below is what I got so far
