描述

When using a local cluster like minikube, where the built images are loaded directly into the cluster's container runtime, a user will encounter see a deployment failure should they specify an imagePullPolicy: Always. Skaffold should transform the manifests and either remove such pull-policies or possibly transform them to imagePullPolicy: Never.

研究方向
Investigate how Skaffold currently handles manifest transformation in deploy steps, likely in `pkg/skaffold/deploy/`. Consider adding a flag or automatic detection of local cluster (e.g., minikube) to rewrite imagePullPolicy to Never or remove it. Review existing code for similar manifest mutations, such as adding labels or namespaces, and follow that pattern. Check comments in the issue for any specific implementation hints.
