Deploy Configs Across Namespaces

MediumPython

Problem

Given a configuration payload represented as a JSON string and a list of Kubernetes namespace names, write a function that returns an ordered deployment plan. Each config object contains name, version, and content. For every namespace, include one deployment action per unique (name, version) pair, keeping only the last occurrence from the input JSON while preserving the final effective order.

Constraints

  • 1 <= len(namespaces) <= 10^3
  • 0 <= number of config objects <= 10^4
  • Each config object contains string fields name, version, and content
  • Namespace names are non-empty strings
  • Invalid JSON or malformed config objects should raise ValueError

Function Signature
