SunCertPathBuilderException when running HonoExampleApplication

Question

I was following the steps in https://www.eclipse.org/hono/docs/dev-guide/java_client_consumer/ to start the example Hono client. From the hono-client-examples folder I ran this command -

    mvn exec:java -Dexec.mainClass=org.eclipse.hono.vertx.example.HonoExampleApplication

But I get an error that it can't connect to AMQP 1.0 container... Failed to create an SSL connection. The log is here - [https://docdro.id/GOlMORV] Please let know how to fix this.

updated with more details

This is the output from minikube start

C:\WINDOWS\system32>minikube start --cpus 2 --memory 4192 * minikube v1.12.3 on Microsoft Windows 10 Home Single Language 10.0.18363 Build 18363 * Using the virtualbox driver based on existing profile * Starting control plane node minikube in cluster minikube * Updating the running virtualbox "minikube" VM ... * Found network options: - NO_PROXY=192.168.99.100,192.168.99.108 - no_proxy=192.168.99.100,192.168.99.108 * Preparing Kubernetes v1.18.3 on Docker 19.03.12 ... - env NO_PROXY=192.168.99.100,192.168.99.108 * Verifying Kubernetes components... * Enabled addons: default-storageclass, storage-provisioner * Done! kubectl is now configured to use "minikube"

and the output from minikube tunnel is here -

Status: machine: minikube pid: 11672 route: 10.96.0.0/12 -> 192.168.99.106 minikube: Running services: [eclipse-hono-adapter-amqp-vertx, eclipse-hono-adapter-http-vertx, eclipse-hono-adapter-mqtt-vertx, eclipse-hono-dispatch-router-ext, eclipse-hono-service-device-registry-ext] errors: minikube: no errors router: no errors loadbalancer emulator: no errors

what Hono instance are your trying to connect to? If you are not connecting to an instance running on localhost then you need to provide the host and port that you want to connect to, e.g. `mvn exec:java -Dexec.mainClass=org.eclipse.hono.vertx.example.HonoExampleApplication -Dconsumer.host=192.168.99.100 -Dconsumer.port=15671` — Kai Hudalla, Aug 21 '20 at 13:40
How do I find out which is the ipaddress and port of the hono instance? I have updated the ticket with more details. I tried with the address:port from echo $DOCKER_HOST command, I tried with the ip address from minikube start - 192.168.99.106 , it was the same error. Now I edited the file honoexampleconstants with 192.168.99.100 as consumer host and 15671 as port , there is no certificate error anymore but it still cannot connect o the AMQP network. here is the latest log - https://docdro.id/oRQTUx2 — nina, Aug 21 '20 at 14:26

Assuming that you are running Hono on a local minikube cluster with minikube tunnel running, you can determine the IP address and port of Hono's northbound API as follows (replace hono with the namespace that you have installed Hono to):

kubectl get service -n hono

The output should look something like

NAME                               TYPE           CLUSTER-IP       EXTERNAL-IP      PORT(S)                           AGE

The northbound API's IP address is the one listed for the hono-dispatch-router-ext in column EXTERNAL-IP. The TLS protected port (AMQPS) is 15671.
