Delivery Assistant

If you would like to extend the delivery sequence with the capabilities of the delivery assistant, just add the approval task to a sequence in your shipyard, as shown by the example of the delivery sequence in the staging stage:

- name: "staging"
  sequences:
    - name: "delivery"
      triggeredOn:
        - event: "dev.delivery.finished"
      tasks:
        - name: "approval"
          properties:
            pass: "manual"
            warning: "manual"
        - name: "deployment"
          properties:
            deploymentstrategy: "blue_green_service"
        - name: "test"
          properties:
            teststrategy: "performance"
        - name: "evaluation"
        - name: "release"

If this task is in place, you can control how to proceed with the delivery depending on the evaluation result from the previous stage. You have the options to configure this as follows:

Evaluation result Option: manual Option: automatic
If evaluation returned is pass manual - the user has to manually approve/decline it. automatic- Keptn automatically approves it.
If evaluation returned is warning manual - the user has to manually approve/decline it. automatic - Keptn automatically approves it.

Example - Regardless of the evaluation result, the user must approve or decline it:

- name: "approval"
  properties:
    pass: "manual"
    warning: "manual"

Example - Automatically continue when result pass, but ask for approval when a warning is returned:

- name: "approval"
  properties:
    pass: "automatic"
    warning: "manual"

Approve or decline an open approval with Keptn Bridge

  • To approve/decline an approval, open the Environment view and click on the stage that has a pending approval. When there are pending approvals for a service available, the service tile is expanded automatically. Additionally, you can filter the services to see only services with pending approvals by clicking on the blue icon.

  • By clicking on the green checkmark, the deployment will be approved. You can also decline by clicking on the red abort button.

Approve or decline an open approval with Keptn CLI

  • To fetch a list of open approvals, Keptn CLI provides the keptn get event approval.triggered command:

    $ keptn get event approval.triggered --project=sockshop --stage=production
    Starting to get approval.triggered events
    {
        "contenttype": "application/json",
        "data": {
            "deploymentstrategy": "blue_green_service",
            "image": "docker.io/keptnexamples/carts",
            "labels": null,
            "project": "sockshop",
            "result": "warning",
            "service": "carts",
            "stage": "production",
            "tag": "0.13.2",
            "teststrategy": "performance"
        },
        "id": "5bf26759-4afa-4045-8ccf-81bc398c2fcd",

        "type": "sh.keptn.event.approval.triggered"
    }
    
  • In addition, by using the command keptn send-event approval.finished the CLI prints a list of open approvals and allows you to choose which one you want to approve/decline:

    $ keptn send event approval.finished --project=ck-sockshop --stage=production --service=carts
    Starting to send approval.finished event
