Kafka install timesout in the grpc.kafka.proxy example

[vordimous]

./setup.sh 
+ helm install zilla-grpc-kafka-proxy-kafka chart --namespace zilla-grpc-kafka-proxy --create-namespace --wait --timeout 2m
Error: INSTALLATION FAILED: timed out waiting for the condition

Kakfa looks to have started correctly so I manually finish the ./startup.sh commands which succeed. However the first grpcurl command just hangs.

I attempted to list the kafka topics:

kcat -b localhost:9092 -L

@vordimous I'm not able to reproduce this on main.

Zilla has been installed.

This is how to check zilla logs:
--------------------------------
$ export ZILLA_POD=$(kubectl get pods --namespace zilla-grpc-kafka-proxy --selector app.kubernetes.io/instance=zilla-grpc-kafka-proxy -o json | jq -r '.items[0].metadata.name')
$ kubectl logs --namespace zilla-grpc-kafka-proxy $ZILLA_POD

This is how to expose zilla with port-forward:
----------------------------------------------
$ export SERVICE_PORTS=$(kubectl get svc --namespace zilla-grpc-kafka-proxy zilla-grpc-kafka-proxy --template "{{ range .spec.ports }}{{.port}} {{ end }}")
$ eval "kubectl port-forward --namespace zilla-grpc-kafka-proxy service/zilla-grpc-kafka-proxy $SERVICE_PORTS" > /tmp/kubectl-zilla.log 2>&1 &

# cleanup:
$ pgrep kubectl && killall kubectl

Note that I did also execute the following command first, per the README.

docker build -t zilla-examples/grpc-echo:latest .

[vordimous]

ran again and didn't hit the timeout.

Looks good to me, too.

Bitnami only provides AMD64 images for kafka, so if you run it on an ARM64 MacBook, java/kafka will run in emulation mode, which can result in an error where kafka won't start in very rare cases (though I haven't seen this error lately at all).
