Promote your release and manage approvals

This page describes how to promote an existing Google Cloud Deploy release to the next target in a delivery pipeline progression.

Before you begin

This page assumes you have already created a release.

Promote the release

When your release is deployed into a target defined in your delivery pipeline, you can promote it to the next target:

gcloud

gcloud deploy releases promote --release=RELEASE_NAME \
                               --delivery-pipeline=PIPELINE_NAME \
                               --region=REGION

Where:

RELEASE_NAME is the name of the release you're promoting.

PIPELINE_NAME is the name of the delivery pipeline you're using to manage deployment of this release.

REGION is the name of the region in which the release was created, for example us-central1. This is required.

See the Google Cloud SDK reference for more information about the gcloud deploy releases promote command.

Console

  1. Open the Delivery pipelines page.

  2. Click your pipeline shown in the list of delivery pipelines.

    The Delivery pipeline details page shows a graphical representation of your delivery pipeline's progress.

  3. On the first target in the delivery pipeline visualization, click Promote.

    The Promote release dialog is shown. It shows the details of the target you're promoting to.

  4. Click Promote.

If the delivery pipeline or target has changed since the release was created, Google Cloud Deploy returns a message indicating a possible mismatch, and prompts you to confirm the promotion. You can respond n to the prompt and examine the differences between the pipeline versions before you proceed. If you choose to promote anyway, the release is deployed according to the delivery pipeline as it was defined when the release was created. See Pipeline instances per release for more information about pipeline mismatches.

Google Cloud Deploy creates a rollout for the release into the destination target, and the release is queued for deployment. When it's deployed, the delivery pipeline visualization shows that fact:

Manage approvals for a delivery pipeline

You can require approval for any target, and you can approve or reject releases into that target.

Approvals can be managed programmatically by integrating your workflow management system (such as ServiceNow), or other system, with Google Cloud Deploy using Pub/Sub and the Google Cloud Deploy API.

Require approval

To require approval on any target, set requireApproval to true in the target configuration:

     apiVersion: deploy.cloud.google.com/v1
     kind: Target
     metadata:
      name:
     description:
     requireApproval: true

See Delivery pipeline configuration for further details.

When a rollout is pending approval, users or systems that subscribe to the cd-approvals Pub/Sub topic receive notification and can then approve or reject the rollout.

Approve or reject a rollout

Each target can require approval before any release is deployed to it. When you promote to a target that requires approval, Google Cloud Deploy publishes a Pub/Sub message to the cd-approvals topic.

Any user or service account with the role roles/clouddeploy.approver can approve a Google Cloud Deploy rollout to a target that requires approval.

Your integrated workflow management system, having received an approval-required notification using service notifications, can approve or reject the rollout using the Google Cloud Deploy API.

Approve or reject manually

Console

  1. In the Google Cloud console, navigate to the Google Cloud Deploy Delivery pipelines page to view of list of your available delivery pipelines.

    Open the Delivery pipelines page

    The list of delivery pipelines is shown in Google Cloud console. Delivery pipelines that have been configured but not registered with the Google Cloud Deployservice are not shown.

  2. Click the name of the delivery pipeline.

    The pipeline visualization is shown. If approval is pending, and if you have the roles/clouddeploy.approver role, or equivalent permissions, the visualization includes a Review link.

  3. Click Review.

    A list is shown of rollouts pending approval.

  4. Click Review.

    The Approve rollout screen is shown.

rollout with approval pending

    The Manifest diff tab shows any changes to the rendered manifest from the currently deployed version (if any) to the one you're now approving (or rejecting).

  5. Click Approve or Reject.

    If you approve, your application is deployed into the target. If you reject, the application is not deployed, and can't be approved later unless re-promoted.

gcloud

A user with the roles/clouddeploy.approver role can manually approve or reject a rollout. To approve:

gcloud deploy rollouts approve rollout-name --delivery-pipeline=pipeline-name \
                                                                   --region=region \
                                                                   --release=release-name

To reject:

gcloud deploy rollouts reject rollout-name --delivery-pipeline=pipeline-name \
                                                                  --region=region \
                                                                  --release=release-name
