chained-function-serving benchmark error when running ./test-client -addr <HOSTNAME>:<PORT>

[rjclemens]

Describe the bug
Below are our kn services currently running (specifically producer and consumer):

When we run the command ./test-client -addr producer.default.192.168.1.240.sslip.io:80 we get the error
could not greet: rpc error: code = Unimplemented desc = unknown service helloworld.Greeter

We also get a similar error when running make invoker
When invoking the producer function with ./invoker -port 50051 -dbg -time 60 -rps 0.016667 we get the following error:

DEBU[2022-09-18T16:29:54.773560018-06:00] Debug logging is enabled INFO[2022-09-18T16:29:54.773674012-06:00] Reading the endpoints from the file: endpoints.json DEBU[2022-09-18T16:29:54.773823436-06:00] Invoking: producer.default.192.168.1.240.sslip.io:80 WARN[2022-09-18T16:29:56.486666637-06:00] Failed to invoke producer.default.192.168.1.240.sslip.io:80, err=rpc error: code = Unimplemented desc = unknown service helloworld.Greeter DEBU[2022-09-18T16:29:56.486812565-06:00] Invoked producer.default.192.168.1.240.sslip.io in 1712988 usec

To Reproduce
Follow commands underneath https://github.com/ease-lab/vSwarm/blob/main/docs/running_benchmarks.md, specifically step 2. We tried both ./invoker and the alternative ./test-client

Expected behavior
We expected not to see any errors so we could advance to the next step (tracing)

Logs
Our service-producer and service-consumer files were as follows:

service-producer.yaml:
apiVersion: serving.knative.dev/v1 kind: Service metadata: name: producer namespace: default spec: template: spec: containers: - image: docker.io/vhiveease/chained-functions-serving-producer:latest imagePullPolicy: Always args: ["-addr", "consumer.default.svc.cluster.local"] ports: # For h2c, see https://knative.tips/networking/http2/ - name: h2c containerPort: 80 env: - name: GUEST_PORT # Port on which the firecracker-containerd container is accepting requests value: "50051" - name: GUEST_IMAGE # Container image to use for firecracker-containerd container value: "docker.io/vhiveease/fibonacci-python:latest"

service-consumer.yaml:
apiVersion: serving.knative.dev/v1 kind: Service metadata: name: consumer namespace: default spec: template: spec: containers: - image: docker.io/vhiveease/chained-functions-serving-consumer:latest imagePullPolicy: Always ports: # For h2c, see https://knative.tips/networking/http2/ - name: h2c containerPort: 80 env: - name: GUEST_PORT # Port on which the firecracker-containerd container is accepting requests value: "50051" - name: GUEST_IMAGE # Container image to use for firecracker-containerd container value: "docker.io/vhiveease/fibonacci-python:latest"

When we attempted to run the test-client alternative since make invoker was not working, we tried every combination of 50051, 80 in containerPort and GUEST_PORT. Specifically, the combination above (80/50051) returned the error Could not invoke gRPC function: rpc error: code = Unimplemented desc =” while all other combinations resulted in either a stalling error or a no connection error.

@dhschall any updates on that?

Ok this is weird. Why is the "docker.io/vhiveease/fibonacci-python:latest" in service-consumer.yaml?
It's a completely different function.
