Spec score 8.0 #11 of 23 in Local Kubernetes Tools

What it is

Talos Linux is an operating system designed for Kubernetes, with machine state set declaratively and node management handled through a secured gRPC API using mutual TLS. It has no SSH, shell, or package manager. The system contains fewer than 50 binaries and has a 100MB footprint. Operating system and Kubernetes upgrades are delivered together in an atomic image that supports rollback. Security capabilities include CIS hardening, SELinux, and trusted boot; Talos itself does not collect telemetry. It runs on cloud platforms, bare metal, virtualized systems, single-board computers, and local Docker or QEMU environments, on amd64 and arm64 architectures. Talos Omni manages cluster provisioning, upgrades, configuration, and backups, and is available as SaaS or self-hosted. The open-source Talos Linux plan is free. Talos Enterprise Linux costs $1,000 a year, billed per node, with a 10-node minimum. That plan includes Omni, 24/7/365 support, and FIPS 140-3 builds.
