Alarm package test

Create a alarm trigger every-20 by the following command:

wsk trigger create every-20 --feed /whisk.system/alarms/alarm --param cron "*/20 * * * * *" -i

Check activation log to see every-20 is triggered every 20 seconds.

wsk activation poll -i

Kafka package test

Create a kafka package binding:

wsk package bind /whisk.system/messaging myKafkaPkg -p brokers "[\"kafka_host1:9093\", \"kafka_host2:9093\"]" -i

Create a trigger:

wsk trigger create MyKafkaTrigger -f myKafkaPkg/kafkaFeed -p topic in-topic -i

Send a message to kafka topic by invoking the action kafkaProduce:

wsk action invoke myKafkaPkg/kafkaProduce -p topic in-topic -p value "this is a message" -i

Check activation log to see MyKafkaTrigger is triggered when a new message is sent.

wsk activation poll -i
