Error message

rendering manifests: %w

What it means

Wraps a failure from Runner.Render during `skaffold deploy`. Deploy builds the artifacts, renders the manifests, then deploys; when rendering fails the deploy aborts before touching the cluster. The wrapped errR contains the renderer's own message (kustomize, helm, or kpt failure).

Solutions

1. Read the wrapped renderer error and fix the offending manifest/chart/overlay
2. Run `skaffold render` alone to reproduce and debug rendering in isolation
3. Pin or update kustomize/kubectl versions (skaffold uses its own kustomize; check `skaffold version` compatibility)
4. Verify remote bases and helm repos are reachable

Example fix

// before: skaffold.yaml points at a removed overlay
// skaffold.yaml: kustomize: { paths: ["overlays/staging"] }  # gone
// after: restore or correct the path
 kustomize:
   paths: ["overlays/dev"]

# catch render issues before deploy
skaffold render --output /tmp/rendered.yaml || echo "fix manifests first"
kustomize build overlays/dev >/dev/null && echo "kustomize OK"

if err := deploy(); err != nil {
    if strings.Contains(err.Error(), "rendering manifests:") {
        // drop to `skaffold render` for the detailed renderer error
    }
}

When it happens

Trigger: `skaffold deploy` (or run/dev reaching deploy) invokes r.Render after a successful build and the renderer returns an error — broken kustomize overlay, helm chart error, kpt failure, or unresolvable remote bases.

Common situations: Deleted or renamed kustomize bases/patches; helm chart values invalid; network failure fetching remote manifests; kustomize/kubectl version mismatch with the manifests.
