Error message

rendering manifests: %w

What it means

Wraps a failure from Runner.Render during `skaffold delete`. After building, delete renders the manifests to determine which resources to clean up; render failures (manifest templating, kustomize/kpt errors, hydration problems) abort the cleanup. The wrapped errR/err carries the renderer-specific cause.

Solutions

1. Read the wrapped error for the renderer-specific cause (kustomize/kpt/helm) and fix the manifest source
2. Restore the manifest files/config to the state used at deploy time
3. Fall back to manual cleanup: kubectl delete on the deployed resources or `kubectl delete all -l <app-label>`
4. Run `skaffold render` standalone to debug the render pipeline

Example fix

// before: kustomization.yml references missing secret-generator
// after
rm -rf overlays/dev/secret-generator.yaml  # or restore the file
skaffold render   # confirm render succeeds before delete

# validate manifests render before relying on delete
skaffold render --output /tmp/check.yaml && echo "render OK"

if err := run(); err != nil {
    if strings.Contains(err.Error(), "rendering manifests:") {
        // fall back to kubectl-based cleanup using stored manifests
    }
}

When it happens

Trigger: `skaffold delete` reaches r.Render and the renderer fails: bad kustomize overlay, kpt/helm templating error, missing remote base, or invalid manifests in skaffold.yaml.

Common situations: Kustomize patches referencing files that no longer exist; helm values changed; kpt function failing; user edited manifests after deploy so they no longer render.
