  Welcome to the official Kubernetes Examples repository! This curated collection,
  stewarded by SIG Apps, provides high-quality, educational examples for running a
  diverse range of applications and workloads on Kubernetes.
  Our goal is to offer a central hub where you can:
  Discover
  practical implementations for various use cases.
  Learn
  common patterns and best practices for deploying applications on Kubernetes.
  Explore
  configurations for general-purpose applications as well as specialized
  ones like AI/ML workloads and platforms.
  Browse Examples
  We encourage you to explore the subdirectories to find examples relevant to your needs.
  Examples are organized into categories, such as:
  ai
  : Demonstrations of AI/ML model training, serving, end-to-end platform
  reference manifests, and MLOps toolchains.
  ... (and more as the collection grows!)
  Each example includes its own detailed
  README.md
  file covering:
  Purpose and learning objectives
  Prerequisites (including Kubernetes version and hardware if applicable)
  Step-by-step deployment instructions
  Verification and cleanup commands
  Key Kubernetes concepts used
