What is Talos?
Talos is a modern OS designed to be secure, immutable, and minimal.
Its purpose is to host Kubernetes clusters, so it is tightly
integrated with Kubernetes.
Talos is based on the Linux kernel, and supports most cloud
platforms, bare metal, and most virtualization platforms. All system
management is done via an API, and there is no shell or interactive
console.
Why Talos?
Security
Talos reduces your attack surface by practicing the Principle of
Least Privilege (PoLP) and by securing the API with mutual TLS
(mTLS) authentication.
Predictability
Talos eliminates unneeded variables and reduces unknown factors in
your environment by employing immutable infrastructure ideology.
Evolvability
Talos simplifies your architecture and increases your ability to
easily accommodate future changes.
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
Talos is hardened by design and configuration:
-
We follow the
Kernel Self Protection Project
configuration recommendations.
-
We enable mutual TLS for the API.
-
We enforce the settings and configurations described in the
CIS
guidelines.
Immutable
Talos improves its security posture further by mounting the root
filesystem as read-only and removing any host-level access by
traditional means 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
We are committed to an n-1 adoption rate of upstream
Kubernetes, and the latest LTS Linux kernel will always be used.
