API versioning

Kubernetes grows continuously. Its features change and this results in the API changing as well. To deal with those changes and to not break compatibility with existing clients over an extended period of time, Kubernetes supports multiple API versions, each with a different API path, such as /api/v1 or /apis/extensions/v1beta1. There are three API levels in the Kubernetes API specification: alpha, beta, and stable. Let's get to know the difference.
