= JMS Feed Provider

This project acts as Provider Service that helps in implementing OpenWhisk Feeds via https://github.com/apache/incubator-openwhisk/blob/master/docs/feeds.md#implementing-feeds-via-connections[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

• https://github.com/apache/incubator-openwhisk/blob/master/docs/triggers_rules.md[Triggers and Rules]
• https://github.com/apache/incubator-openwhisk/blob/master/docs/feeds.md[Feeds]

[[pre-req]] = Pre-requisite

• Deploy https://activemq.apache.org/artemis to OpenShift using link:./artemis/artemis.yml
• Deploy https://github.com/projectodd/openwhisk-openshift#installing-on-minishift[OpenWhisk on Minishift]
• http://couchdb.apache.org/[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 [code,sh]

---

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]] == Build and Deploy

=== Database

As described in <> section this application uses http://couchdb.apache.org/[Apache CouchDB] to persist the provider trigger data. The following command shows how to deploy CouchDB:

[code,sh]

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 <> section this application uses https://activemq.apache.org/artemis as the Message Broker. The following command shows how to deploy Apache Artemis:

[code,sh]

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

=== Application

[code,sh]

mvn clean package fabric8:deploy

=== Testing
