Multi-stage delivery

Declare a multi-stage delivery sequence in shipyard

The definition of a multi-stage delivery manifests in a so-called Shipyard file. It can hold multiple stages with dedicated and opinionated delivery tasks to execute.

Example: Simple shipyard file with a delivery sequence in the two stages dev and production, whereas dev uses a direct deployment and prod uses blue-green deployment:

apiVersion: spec.keptn.sh/0.2.3
kind: "Shipyard"
metadata:
  name: "shipyard-sockshop"
spec:
  stages:
    - name: "dev"
      sequences:
      - name: "delivery"
        tasks: 
        - name: "deployment"
          properties:
            deploymentstrategy: "direct"
        - name: "release"

    - name: "production"
      sequences:
      - name: "delivery"
        triggeredOn:
          - event: "dev.delivery.finished"
        tasks: 
        - name: "deployment"
          properties:
            deploymentstrategy: "blue_green_service"
        - name: "release"

Example: Extended shipyard with a delivery sequence in three stages dev, hardening and production in combination with tests:

apiVersion: spec.keptn.sh/0.2.3
kind: "Shipyard"
metadata:
  name: "shipyard-sockshop"
spec:
  stages:
    - name: "dev"
      sequences:
      - name: "delivery"
        tasks: 
        - name: "deployment"
          properties:
            deploymentstrategy: "direct"
        - name: "test"
          properties:
            teststrategy: "functional"
        - name: "evaluation"
        - name: "release"

    - name: "hardening"
      sequences:
      - name: "delivery"
        triggeredOn:
          - event: "dev.delivery.finished"
        tasks: 
        - name: "deployment"
          properties:
            deploymentstrategy: "blue_green_service"
        - name: "test"
          properties:
            teststrategy: "functional"
        - name: "evaluation"
        - name: "release"

    - name: "production"
      sequences:
      - name: "delivery"
        triggeredOn:
          - event: "hardening.delivery.finished"
        tasks: 
        - name: "deployment"
          properties:
            deploymentstrategy: "blue_green_service"
        - name: "release"

Example: Extended shipyard with two delivery sequence with varying deployment strategies (e.g., delivery is used for a Java-service, whereas delivery-direct is used for a database):

apiVersion: spec.keptn.sh/0.2.3
kind: "Shipyard"
metadata:
  name: "shipyard-sockshop"
spec:
  stages:
    - name: "production"
      sequences:
        - name: "delivery"
          tasks:
            - name: "deployment"
              properties:
                deploymentstrategy: "blue_green_service"
            - name: "release"

        - name: "delivery-direct"
          tasks:
            - name: "deployment"
              properties:
                deploymentstrategy: "direct"
            - name: "release"

Create project with multi-stage delivery

After declaring the delivery for a project in a shipyard, you are ready to create a Keptn project as explained in create a project.

Trigger a multi-stage delivery

After creating a project and creating your service(s), you can trigger a delivery using the Keptn CLI or API.

Use the command keptn trigger delivery:

keptn trigger delivery --project=$PROJECTNAME --service=$SERVICENAME --image=$IMAGE --tag=$TAG

Specify a valid Keptn CloudEvent of type sh.keptn.event.[STAGENAME].delivery.triggered and store it as JSON file, e.g., trigger_delivery.json

{
  "contenttype": "application/json",
  "data": {
    "project": "[PROJECTNAME]",
    "service": "[SERVICENAME]",
    "stage": "[STAGENAME]",
    "configurationChange": {
      "values": {
        "image": "keptn-examples/carts:0.11.3"
      }
    }
  },
  "source": "https://github.com/keptn/keptn/cli",
  "specversion": "1.0",
  "type": "sh.keptn.event.[STAGENAME].delivery.triggered"
}

Trigger a delivery with a POST request on /event:

curl -X POST "${KEPTN_ENDPOINT}/v1/event" \
-H "accept: application/json; charset=utf-8" \
-H "x-token: ${KEPTN_API_TOKEN}" \
-H "Content-Type: application/json; charset=utf-8" \
-d @./trigger_delivery.json
