Meridian

Meridian is a Kubernetes-native platform lifecycle controller for management clusters.

It manages the lifecycle of a Kubernetes fleet: provisioning, identity management, upgrade, and decommission. Cluster API is the provisioning engine beneath it, while Meridian defines deterministic fleet identity and replacement semantics on top.

Scope

• Declarative cluster roles and platform profiles.
• Provider overlays and environment-aware fleet topology.
• Blue/green lifecycle orchestration for cluster replacement.
• Health-gated rollout progression with Fathom integration.

Design boundary

Meridian coordinates fleet lifecycle state. It does not replace Kubernetes, act as a package manager, or become a GitOps engine.
