Talos Linux
What Talos Linux is
Talos Linux is an immutable, API-driven operating system purpose-built for Kubernetes. It has no SSH, shell, or package manager; node interaction instead uses a secured gRPC API with mutual TLS. The system has a 100MB footprint and fewer than 50 binaries. Machine state is declared in configuration, and operating system and Kubernetes upgrades are delivered together as an atomic image with rollback safety. Security capabilities include CIS hardening, mutual TLS, SELinux, and trusted boot. Talos runs on cloud platforms, bare metal, virtualized platforms, single-board computers, and local Docker or QEMU environments, on amd64 and arm64 architectures. The operating system is free and open source under MPL-2.0 and does not collect telemetry. Talos Omni manages provisioning, upgrades, configuration, and backups across clusters, with SaaS and self-hosted options. The free Talos Linux plan includes community support. Talos Enterprise Linux costs $1,000 a year, billed per node, with a 10-node minimum; Omni, 24/7/365 support, and FIPS 140-3 builds are included. Sidero also lists support with SLA-backed response times, Kubernetes control-plane coverage, and guidance for Cilium, MetalLB, and Rook-Ceph.
