slack/message
Cluster UUID that created the alert
JSON formatted data for Slack Webhook postings.
Must be formatting in Slack acceptable JSON.
Uses .ParamExpand so that operators can insert information into the message
without having to customize the task. This allows you to dynamically embed Params
into Slack messages.
For example, using a Trigger with MergeDataIntoParams: true
exposes properties from the Object causing the Event. If that Event is an Alert,
then you can include the Level and Name of the Alert in your Slack message:
{"text":"{{.Param "Level"}} Alert {{.Param "Name"}} from Digital Rebar at {{.ApiURL }}"}
