JMS Feed Provider

This project acts as Provider Service that helps in implementing OpenWhisk Feeds via Connections

In this demo provider service registers JMS Listeners to make JMS Destinations Queues/Topics a event source to OpenWhisk triggers. When ever a message is sent to the JMS Destination this Feed will fire all the associated Triggers with event data as payload.

Note	This demo assumes are messages are sent as JSON string.

Refer to the following links for more information on Triggers, Rules and Feeds

• Triggers and Rules

• Feeds

Pre-requisite

• Deploy https://activemq.apache.org/artemis to OpenShift using link:./artemis/artemis.yml

• Deploy OpenWhisk on Minishift

• Apache CouchDB will be used to persist the trigger data

Important

For all the CLI commands to work as it is, deploy OpenWhisk to a OpenShift Project called openwhisk Deploy applications infinispan and infinispan-feed-provider to myproject workspace make user developer as admin for both these projects via oc adm policy add-role-to-user admin developer -n openwhisk

• Enable the anyuid and admin-user addons, anyuid is required for CouchDB to run as user with anyuid

Build and Deploy

Database

As described in Pre-requisite section this application uses Apache CouchDB to persist the provider trigger data. The following command shows how to deploy CouchDB:

oc apply -f couchdb/couchdb.yaml (1)

1. Deploys CouchDB in OpenShift and sets up the CouchDB for Single Node Environment as said in http://docs.couchdb.org/en/2.1.1/install/setup.html#install-setup

Note	OpenWhisk Deployment already has CouchDB deployed, if you wish to use it you can alter the spring.couchbase.bootstrap-hosts in link:./src/main/resources/application.yaml. Just for sake of clarity and to prevent any mess with OpenWhisk data its recommened to deploy seperate.

Message Broker

As described in Pre-requisite section this application uses https://activemq.apache.org/artemis as the Message Broker. The following command shows how to deploy Apache Artemis:

oc apply -f artemis/artemis.yml (1)

1. Deploys Apache Artemis in OpenShift

Warning

Currently the Apache Artemis Console is not accessible via nip.io ip in Minishift, hence the dpeloyment has defined node ports for enabling access outside cluster

mvn clean package fabric8:deploy
