**Type:** Problem & solution

## Summary

Kube AuthKit is a lightweight Python library that unifies Kubernetes and OpenShift authentication behind a single API, eliminating conditional code paths across local, pod, notebook, and CI/CD environments. It supports four strategies—kubeconfig, in-cluster, OIDC, and OpenShift OAuth—auto-detected by an AuthFactory that probes environment variables and in-cluster markers in a defined order. The library handles token lifecycle transparently, with in-memory storage by default and optional OS keyring persistence for local development to avoid repeated logins. It provides two OIDC flows: device code for headless environments and authorization code with PKCE for interactive applications, both with automatic token refresh. Kube AuthKit returns a standard Kubernetes Python client ApiClient, ensuring full compatibility with the official library, and is actively maintained by the Open Data Hub community for OpenShift AI environments.

## Context

Authentication fragmentation in Kubernetes and OpenShift Python applications: different environments (local development, pods, notebooks, CI/CD pipelines) require different authentication methods (kubeconfig, service account tokens, OIDC, OpenShift OAuth), each with its own setup and token lifecycle. The official Kubernetes Python client handles kubeconfig and in-cluster auth but leaves OIDC and OpenShift OAuth to the developer, leading to conditional code paths and duplicated token-handling logic.

## Approach / What changed

The library uses the Strategy Pattern with four authentication strategies (kubeconfig, in-cluster service account, OIDC, and OpenShift OAuth) behind a common interface. An AuthFactory auto-detects the correct strategy by probing environment variables and in-cluster markers in a defined order. Token lifecycle management is handled transparently with in-memory storage by default and optional OS keyring persistence for local development. The library returns a standard Kubernetes Python client ApiClient.

## Takeaways

- Kube AuthKit reduces authentication to a single function call, auto-detecting the environment and selecting the correct strategy from kubeconfig, in-cluster, OIDC, or OpenShift OAuth.
- It supports two OIDC flows: device code for headless environments and authorization code with PKCE for interactive applications, both with automatic token refresh.
- Token lifecycle management is handled transparently with in-memory storage by default and optional OS keyring persistence to avoid repeated logins during local development.

## FAQ

### How does Kube AuthKit handle different environments?

Kube AuthKit uses an AuthFactory that probes environment variables and in-cluster markers in a defined order: first OIDC environment variables, then a Bearer token, then in-cluster markers (KUBERNETES\_SERVICE\_HOST and mounted service account), and finally falls back to kubeconfig. This auto-detection selects the correct authentication strategy without manual configuration.

### What OIDC flows are supported?

It supports two OAuth 2.0 flows: device code flow for headless environments and CLI tools, and authorization code flow with PKCE for interactive user-facing applications. Both flows handle OIDC discovery automatically and manage token refresh.

### How does token lifecycle management work?

Tokens are stored in-memory by default, which is secure for automated CI/CD pipelines and headless environments. Optionally, tokens can be persisted in the OS keyring (macOS Keychain, GNOME Keyring, or Windows Credential Vault) to avoid repeated authentication during local development; the first run requires interactive authentication, but subsequent runs reuse the stored refresh token silently.
