Question

Your team uses Cloud Deploy to release a payments microservice to GKE. The delivery pipeline defines a canary strategy with three phases (10%, 50%, 100%). Compliance requires that a smoke test runs against every phase's canary before that phase's traffic percentage is applied, and the release must automatically halt if any smoke test fails. Which Cloud Deploy configuration meets these requirements?

Accepted Answer

Add a `verify` phase to the canary strategy and enable verification on each phase; Cloud Deploy runs the Skaffold-defined verify job after deploying each canary percentage and fails the rollout if it returns non-zero.

Answer

Add a `predeploy` action hook that runs the smoke tests before deploying, and configure a retry policy so failed tests reroll automatically.

Answer

Configure a Cloud Build trigger that runs smoke tests on a schedule and stops the Cloud Deploy release through the API if tests fail.

Answer

Use a `postdeploy` hook only on the final 100% phase to run all smoke tests at once, ensuring the fully deployed service is validated before promotion.
