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.
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.
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.
Talos runs in memory from a SquashFS, and persists nothing, leaving the primary disk entirely to Kubernetes.
We are committed to staying current with the latest stable versions of Kubernetes, and Linux.
