From Empty Cluster to Production-Ready#

This is the definitive operational plan for taking a fresh Kubernetes cluster and making it production-ready. Each phase builds on the previous one, with verification steps between phases and rollback notes where applicable. An agent should be able to follow this sequence end-to-end.

Estimated timeline: 5 days for a single operator. Phases 1-2 are blocking prerequisites. Phases 3-6 can partially overlap.

Phase 1 – Foundation (Day 1)#

Everything else depends on a healthy cluster with proper namespacing and storage. Do not proceed until every verification step passes.

Prompt Engineering for Infrastructure Operations#

Infrastructure prompts differ from general-purpose prompts in one critical way: the output often drives real actions on real systems. A hallucinated filename in a creative writing task is harmless. A hallucinated resource name in a Kubernetes delete command causes an outage. Every prompt pattern here is designed with that asymmetry in mind – prioritizing correctness and safety over cleverness.

Structured Output for Infrastructure Data#

Infrastructure operations produce structured data: IP addresses, resource names, status codes, configuration values. Free-form text responses create parsing fragility. Force structured output from the start.
