Kubernetes Access MVP

Kubernetes Access MVP is about cutting to the essentials—only what you need to protect, provision, and scale access in a live environment. No tangled RBAC diagrams that grow stale before they’re deployed. No sprawling IAM configs that collapse under their own weight. Just the minimum viable setup that still passes audits, ships fast, and holds under pressure.

Start with RBAC as the foundation. Create role definitions that are scoped to the smallest possible set of actions. Bind them tightly to specific service accounts, not to large groups. Automate these mappings so they don’t drift.

Limit cluster-wide roles to a short, reviewed list. Push everything else down to namespace-level permissions. Namespaces give you natural isolation and clear boundaries. Enforce these boundaries with admission controllers that block cross-namespace access unless explicitly allowed.

Use Kubernetes-native tools first. Avoid third-party access layers unless they solve a real constraint. Core Kubernetes API verbs—get, list, watch, create, update, delete—are your building blocks. Strip roles of unused verbs.

Audit access continuously. Kubernetes API server logs are the raw truth. Feed them into a log aggregation system. Review permissions monthly, cut unused accounts instantly. Rotate credentials aggressively.

With the MVP in place, expansion is methodical. Add permissions for new services one at a time. Test each before merging. Keep changes small so rollbacks are quick.

Kubernetes Access MVP is not a theory. It is code, configs, and policies you can apply now. Minimal attack surface. Maximum control.
