Hi Team, I'm working alongside @viacheslav-fomin-main. I would like to
provide some context for this issue to help you reproduce if needed.
## The Proto File
Our `.proto` file looks something like this (we package it in
`com.sample.compute:compute-proto:1.0.0-SNAPSHOT`):
```
syntax = "proto3";
package com.sample.compute;
option java_package = "com.sample.compute";
option java_multiple_files = true;
message ComputeRequest {
Script script = 1;
Payload payload = 2;
map<string, string> context = 3;
map<string, string> system_context = 4;
}
message Payload {
bytes payload = 1;
}
message Script {
string type = 1;
string version = 2;
string script = 3;
}
message ComputeResponse {
Payload payload = 1;
map<string, string> context = 2;
map<string, string> system_context = 3;
}
service ComputeService {
rpc Compute(ComputeRequest) returns (ComputeResponse);
rpc ComputeStream(stream ComputeRequest) returns (stream ComputeResponse);
}
```
## The Java Route
Our `SampleGrpcCamelRoute.java` route looks like this:
```
package com.sample.compute.service.grpc;
import com.google.protobuf.ByteString;
import com.sample.compute.ComputeRequest;
import com.sample.compute.ComputeResponse;
import com.sample.compute.Payload;
import org.apache.camel.Message;
import org.apache.camel.builder.RouteBuilder;
import java.nio.charset.StandardCharsets;
public class SampleGrpcCamelRoute extends RouteBuilder {
@Override
public void configure() throws Exception {
fromF("grpc://localhost:9000/com.sample.compute.ComputeService?synchronous=true")
.process(exchange -> {
final Message message = exchange.getMessage();
final ComputeRequest request =
message.getBody(ComputeRequest.class);
final String scriptOutputBody = "Hello World!";
final Payload responsePayload = Payload.newBuilder()
.setPayload(ByteString.copyFrom(scriptOutputBody.getBytes(StandardCharsets.UTF_8)))
.build();
final ComputeResponse response =
ComputeResponse.newBuilder()
.setPayload(responsePayload)
.build();
message.setBody(response);
});
}
}
```
We have verified this route works locally using java unit tests and Apache
Camel ContextTestSupport `org.apache.camel.ContextTestSupport`.
## Running using `kamel` CLI
We run the integration using the following command:
```
kamel run --dev \
-d mvn:com.sample.compute:compute-proto:1.0.0-SNAPSHOT \
-d mvn:org.apache.camel:camel-grpc:3.9.0 \
-d mvn:org.apache.camel:camel-componentdsl:3.9.0 \
SampleGrpcCamelRoute.java
```
Using `kubectl port-forward` on the integration pod we are able to verify
the grpc route is working using the same tests we had run locally.
We tried a plethora of camel-k `trait`s including:
```
--trait container.service-port=9000 \
--trait container.expose=true \
--trait knative.enabled=true \
--trait knative-service.enabled=true \
--trait
knative-service.autoscaling-class=kpa.autoscaling.knative.dev \
--trait knative-service.min-scale=1 \
--trait knative-service.max-scale=1 \
```
Thank you for the support!
