getting pods for namespace %q: %w

Error message

getting pods for namespace %q: %w

What it means

After obtaining a client, containerHook.run lists pods in each configured namespace with client.CoreV1().Pods(ns).List. If the API list call fails, the error is wrapped as 'getting pods for namespace %q: %w'.

Solutions

  1. Verify the namespace exists in the target context: kubectl get ns
  2. Check connectivity/auth: kubectl --context <ctx> -n <ns> get pods
  3. Fix the namespaces list in the skaffold.yaml container hook (typos, wrong context)
  4. Grant RBAC: create a rolebinding allowing 'list' on 'pods' in that namespace

Example fix

// before
namespaces: ["stagging"]  // typo
// after
namespaces: ["staging"]
Defensive patterns

Strategy: retry

Validate before calling

for _, ns := range namespaces {
    if err := exec.Command("kubectl", "--context", ctxName, "get", "ns", ns).Run(); err != nil {
        return fmt.Errorf("namespace %q missing or inaccessible", ns)
    }
}

Try / catch

err := hook.Run(ctx, out)
if err != nil && strings.Contains(err.Error(), "getting pods for namespace") {
    // transient API server errors: retry with backoff
    return retry.Do(func() error { return hook.Run(ctx, out) }, retry.Attempts(3))
}

Prevention

When it happens

Trigger: run iterating h.namespaces where a Pods List call fails — namespace doesn't exist, API server unreachable, or the caller lacks RBAC permission to list pods in that namespace.

Common situations: Hook configured with a namespace not present on the cluster (typo or wrong context); disconnected VPN/offline cluster; service account without 'list pods' RBAC in the namespace; cluster API server temporarily down.
