failed to deploy: %w

Error message

failed to deploy: %w

What it means

This error wraps any failure from the deploy phase of `skaffold run`. After builds and rendering succeed, r.DeployAndLog applies the manifests to the Kubernetes cluster; any deploy error (kubectl/helm failure, cluster unreachable) is wrapped here.

Solutions

  1. Read the wrapped cause after 'failed to deploy:' for the kubectl/helm error
  2. Verify cluster connectivity: kubectl cluster-info and kubectl config current-context
  3. Run `skaffold deploy` (after a successful build) to isolate the deploy step
  4. Fix the underlying cause: correct kubecontext, create missing namespaces, or fix rejected manifests

Example fix

// before
kubectl config use-context prod-cluster // cluster unreachable
// after
kubectl config use-context dev-cluster && skaffold run
Defensive patterns

Strategy: try-catch

Validate before calling

kubectl cluster-info --context $(kubectl config current-context) >/dev/null && echo 'cluster reachable'

Try / catch

err := r.DeployAndLog(ctx, out, bRes, manifestList)
if err != nil {
	if errors.Is(err, context.DeadlineExceeded) {
		// retry or increase timeout
	}
	return fmt.Errorf("failed to deploy: %w", err)
}

Prevention

When it happens

Trigger: Running `skaffold run` when DeployAndLog fails: kubectl apply errors, cluster connection refused, namespace missing, image pull failures, or helm deploy failures.

Common situations: kubectl context points to a nonexistent cluster; RBAC denies apply; invalid manifest rejected by API server; wrong kubeconfig in CI.
