AMQ Broker / MQTT / Camel-Quarkus(JMS)

This has been tested on OpenShift 4.9

Install Operators

First, install the AMQ Broker operator. You can do this through the OpenShift UI as an admin, or by executing the following command using the oc cli as a cluster-admin.

oc apply -k manifests/operators

Generate Certificates

For convenience, you can use the cert.sh script to generate certificates and add them to a Secret. It assumes you are logged in ahead of time with the oc cli so that it can get the apps router url from your cluster.

From a Mac or Linux terminal, run:

./cert.sh mypassword

Where mypassword is any password you would like to use for the keystore. This will use the Java keytool to generate a keystore and trustore, then encode them in a secret that will get added to the manifests/broker directory. This secret is already added to the .gitignore file, so it will not be pushed to your git repo.

Broker Instance

Once the operator is installed and you have generated your certificates/secret, you can create a Broker instance and the Topic.

oc apply -k manifests/broker

Build and Run MQTT Consumer and Producer Application

Once the broker is up and running, you can build and run the "client-mqtt" application in dev mode.

cd client-mqtt
mvn clean quarkus:dev -Dcamel.component.paho.broker-url=$YOUR_AMQ_ROUTE_URL

Build and Run JMS Consumer and Producer Application

Once the broker is up and running, you can build and run the "client-activemq" application in dev mode.

cd client-activemq
mvn clean quarkus:dev -Dcamel.component.activemq.broker-url=$YOUR_AMQ_ROUTE_URL
