What is Talos Linux?

Talos Linux is Linux designed for Kubernetes – secure, immutable, and minimal.

Talos Linux supports cloud platforms, bare metal, and virtualization platforms. All system management is done via an API: there is no ssh, shell or interactive console.

Talos Linux is production ready, and supports some of the largest Kubernetes clusters in the world.

It only takes 3 minutes to launch a Talos cluster on your laptop inside Docker.

Why Talos Linux?

Security

Talos reduces your attack surface. It's minimal, hardened and immutable. All API access is secured with mutual TLS (mTLS) authentication.

Predictability

Talos eliminates configuration drift, reduces unknown factors by employing immutable infrastructure ideology, and delivers atomic updates.

Evolvability

Talos simplifies your architecture, increases your agility, and makes always delivers current stable Kubernetes and Linux versions.

API Driven

Built with Modern Technology

Features

Minimal

Talos consists of only a handful of binaries and shared libraries: just enough to run containerd and a small set of system services.

This aligns with NIST's recommendation in the Application Container Security Guide.

Hardened

Hardened by design:

  • Built with the Kernel Self Protection Project configuration recommendations.
  • All access to the API is secured with Mutual TLS.
  • Settings and configuration described in the CIS guidelines are applied by default.

Immutable

Talos improves security further by mounting the root filesystem as read-only and removing any host-level such as a shell and SSH.

Ephemeral

Talos runs in memory from a SquashFS, and persists nothing, leaving the primary disk entirely to Kubernetes.

Current

Delivers the latest stable versions of Kubernetes and Linux.
