kubectl apply -f dryrun-manifests.yaml
kubectl argo rollouts get rollout dryrun-rollout --watch

In another terminal, cause rollout to happen by updating the rollout image

kubectl argo rollouts set image dryrun-rollout helloworld=hashicorp/http-echo:0.2.3

Notice that the Job completes successfully with exit code 0, but the AnalysisRun never finishes and gets stuck in the Running state.

Cleanup:

kubectl delete rollout dryrun-rollout; kubectl delete service dryrun-service dryrun-service-preview; kubectl delete analysistemplate dryrun-analysis-success dryrun-analysis-failure
