unable to get kubernetes config: %w

Error message

unable to get kubernetes config: %w

What it means

getCurrentContext loads the full kubeconfig via kubectx.CurrentConfig() to resolve the Cluster associated with i.kubeContext. This error wraps a failure to read or parse the Kubernetes client configuration — missing, malformed, or unreadable kubeconfig files, or client-go config loading errors.

Solutions

1. Run `kubectl config view` with the same environment to see the parse error
2. Validate KUBECONFIG points at an existing, readable file: `echo $KUBECONFIG && ls -l $KUBECONFIG`
3. Regenerate the kubeconfig from your provider (e.g. `kind get kubeconfig-path`, `gcloud container clusters get-credentials`, `k3d kubeconfig get`)
4. Check YAML syntax of the kubeconfig if it was hand-edited; remove broken entries from merged KUBECONFIG lists

Example fix

// before: KUBECONFIG points to a missing file
export KUBECONFIG=~/.kube/nonexistent
// after
unset KUBECONFIG  # or export KUBECONFIG=~/.kube/config

// Validate kubeconfig exists and parses before invoking the loader
path := os.Getenv("KUBECONFIG")
if path == "" { path = filepath.Join(homedir.Get(), ".kube", "config") }
data, err := os.ReadFile(path)
if err != nil {
    return fmt.Errorf("kubeconfig unreadable: %w", err)
}
var cfg map[string]interface{}
if err := yaml.Unmarshal(data, &cfg); err != nil {
    return fmt.Errorf("kubeconfig malformed: %w", err)
}

err := loader.LoadImages(ctx, out, artifacts)
if err != nil {
    if strings.Contains(err.Error(), "unable to get kubernetes config") {
        return fmt.Errorf("fix KUBECONFIG/kubeconfig file first: %w", err)
    }
    return err
}

When it happens

Trigger: LoadImages calls getCurrentContext before loading into a kind/k3d cluster; kubectx.CurrentConfig() fails because no kubeconfig exists, KUBECONFIG points to an invalid path, or a kubeconfig file contains invalid YAML/schema.

Common situations: Fresh machine with no ~/.kube/config; KUBECONFIG env var referencing a nonexistent or syntactically broken file; permissions issue on the kubeconfig; a partially written kubeconfig after an interrupted cluster provisioning; malformed entries merged from multiple KUBECONFIG files.
