Trigger tests & evaluation

[jetzlstorfer]

Use the slackbot to trigger tests & evaluation by Keptn and return the result of the evaluation as a result in Slack.

Potential commands:

• @keptnBot deployment-finished project service stage teststrategy deploymentURI
• or with a different start command: @keptnBot start-tests project service stage [testname] [serviceURL]

Actions the bot has to take:

1. send a deployment finished event to the keptn api endpoint
2. wait for a evaluation-done event (attention: only events with the correct keptncontext must be considered)
3. post the evaluation-done event back to slack

Example payload to send from the bot to Keptn:

{
  "type": "sh.keptn.events.deployment-finished",
  "specversion": "0.2",
  "source": "https://github.com/keptn/keptn/helm-service",
  "id": "f2b878d3-03c0-4e8f-bc3f-454bc1b3d79d",
  "time": "2019-06-07T07:02:15.64489Z",
  "contenttype": "application/json",
  "data": {
    "project": "$PROJECT",
    "stage": "$STAGE",
    "service": "$SERVICE",
    "testStrategy": "$TESTSTRATEGY",
    "tag": "0.9.1",
    "image": "docker.io/keptnexamples/carts",
    "labels": {
      "testid": "12345",
      "buildnr": "build17",
      "runby": "JohnDoe"
    },
    "deploymentURI": "http://carts.sockshop-staging.svc.cluster.local"
  }
}

Issues to clarify

1. How to retrieve the Keptn Context ID? Is this needed for a deployment-finished event?

Regarding your issue: If the cloudevent does not contain any Keptn Context ID, the API automatically generates one.

Thanks for clarification!

Some input from another project that is triggered tests in a Jenkins pipeline:
