Talos Linux is an ultra-minimal, security-focused, and fully immutable Linux distribution built from the ground up for Kubernetes. Instead of relying on traditional package managers or SSH, Talos exposes a gRPC-based API for node administration, enabling fully automated, declarative, and reproducible cluster operations. The OS removes unnecessary components such as shell access and mutable system state, significantly reducing the attack surface and operational complexity.

Talos tightly integrates with Kubernetes by managing kubelet, container runtime, and system services as part of a unified, API-driven control plane. Its immutable design ensures consistent behavior across nodes, eliminates configuration drift, and simplifies upgrades through atomic, transactional updates. Talos is widely adopted in production clusters, edge deployments, home labs, and hardened environments where reliability and security are critical.
