Question

Your team uses Google Cloud Deploy to deploy a customer-facing service to GKE. Product management wants each production release to shift traffic gradually: first 10%, then 25%, then 50%, and finally 100%, pausing at each step so operators can observe dashboards before the next phase advances. You must configure this behavior in the delivery pipeline. Which approach meets the requirement with the least custom scripting?

Accepted Answer

Define a canary deployment strategy on the production stage with a canaryDeployment block listing the percentages [10, 25, 50], relying on Cloud Deploy to add the final 100% phase automatically.

Answer

Use a standard (rolling) strategy and write a Cloud Build step after each deploy that manually edits the Kubernetes Service weights before promoting.

Answer

Configure a blue-green strategy with routeUpdateWaitTime set to progressively longer values so traffic bleeds over in increasing increments.

Answer

Define a canary strategy but list every percentage including [10, 25, 50, 100] in the canaryDeployment percentages field to control all four phases explicitly.
