⁠[IMPORTANT]

• For all the CLI commands to work as it is, deploy OpenWhisk to a OpenShift Project called openwhisk ====

== Build and Deploy

[[create-package]] === Create Package

⁠wsk -i package create --shared yes redhatdevelopers <1>

<1> this could be anything, if you change it please update link:./pom.xml[pom.xml] openwhisk.package property

⁠[[create-feed-action]] === Create Feed Action [code,sh]

mvn clean package <1>

⁠wsk action update -a feed true
--main org.jboss.fuse.openwhisk.camel.CamelFeedAction
redhatdevelopers/camel-feed
camel-feed-action/target/camel-feed-action-*.jar

<1> if you have https://github.com/apache/incubator-openwhisk-cli[WSK⁠ CLI] installed, post package

==== Create Trigger, Action and Rule

⁠[code,sh]

wsk trigger create camelTrigger
--feed redhatdevelopers/camel-feed
-p mapping '{ date: "header[CamelTimerFiredTime]", counter: "header[CamelTimerCounter]" }'
-p routeUrl 'timer://foo?fixedRate=true&period=10000'

wsk action create camelTriggerAction camel-feed-action/src/handler.js

⁠wsk rule create camelEntryRule camelTrigger camelTriggerAction

<1> Create a camel route <4> Create a dummy action just to see what parameters are sent via the event source <5> Associate the Trigger with Action via a rule

⁠wsk activation list --limit 1 camelTriggerAction <1> wsk activation result <2>

<1> Check if the camelTriggerAction action is triggered as a result of cache entry addition <2> Check what payload the camelTriggerAction has recevied
