Intent-Based Automation & Kubernetes Operators
 

🔹Understanding Intent-Based Automation

• Declarative vs. Imperative Approach

  • Focus on what you want (desired state) instead of how to get there.

  • Example: “Ensure the system always reaches and maintains State B.”

  • Driven by reconciliation loops:

    • Observe desired state

    • Compare with live state

    • Take actions to reach the desired state
