Integrating Kubernetes with OAuth providers such as Google streamlines user authentication by eliminating the need for separate user databases specific to Kubernetes, which can be a security risk and management challenge. This process involves setting up OAuth credentials in Google Cloud, configuring Minikube with these credentials to accept Google logins, and utilizing tools like k8s-oidc-helper to facilitate the generation of authentication tokens. The integration allows users to authenticate through a familiar web interface and leverages existing account providers, while tools ensure that kubectl can be used effectively to manage Kubernetes resources. However, access control is maintained by defining ClusterRoles and ClusterRoleBindings to prevent unauthorized actions by users who generate OAuth codes.
