The latest version of Talos OS, a modern Kubernetes Stable Hosts operating system, is out since 2020! Updated versions of Kubernetes (version 1.19.3) and Linux are included in version 0.7 (5.9.3). New updates to be released in 2021. You can read this post: Kubernetes with Docker & AWS – Best Online Course Guide.
Features of Talos OS v0.7 Platform
Significant new characteristics include:
1. ARM support:
For all cloud platforms, ARM-based images are now being created. Would you like to run a Kubernetes stable cluster on AWS graviton nodes using Talos OS? They hear ya! ARM support in Talos is still a work in progress—please let us know if you have any questions or run into problems! Soon, expect to see Talos OS on devices such as the Raspberry Pi!
2. Turn to bootloader Grub (replacing syslinux):
This was important to allow ARM support, but also allowed Talos OS to use the robust boot partition xfs filesystem instead of the more fragile vfat. Remember that changing the bootloader means that this update does not have any rollback to the old partition.
3. Installation from ISO:
Talos OS is now simple to install from ISOs: a new “maintenance mode” allows Talos to be installed via ISO without having to generate a configuration file in advance. This function is not yet completely documented, but a web server that is recorded on the console will start booting from an ISO. This maintenance mode and talosctl can be used to supply the configuration to Talos at runtime and to complete the installation.
4. Configuration Update API
A new Configuration Update API that allows you to push and restart a modified node configuration without having to install a whole new node. This allows kernel settings, disk mounts, etc. to be changed on existing nodes.
5. Node configuration
Node configuration files, with several examples of various Talos features that can be allowed, are now more complete and self-documentable. (For a look at how the Talos team was able to automatically create comments from YAML, see the blog post).
6. Revamped documentation
A updated platform for documentation. Comments and reports on bugs are welcomed!
Most of all, this update contains more APIs for the operating system, lots of improvements in reliability and performance, and bug fixes.

At Talos Systems, they have a vision for Kubernetes
Talos was born out of real life Kubernetes experience – and real life problems. The founders had been working with K8s for a few years, running production clusters for SaaS companies that required operational stability and security. Running K8s on a general purpose OS such as RHEL or Ubuntu required a lot of tools to ensure security, and frequent patching and OS upgrades to address flaws in the underlying operating system and packages. These operational headaches introduced fragility into the system.
Talos Systems was born to solve this. A radically new operating system, designed purely for Kubernetes.
Talos OS is not a general-purpose operating system – it is minimal, hardened and immutable. This reduces security vulnerabilities, and makes upgrading, and migrating from one environment to another, much easier.
The Talos platform automates the installation and security of K8s out of the box. In short, it solves the real world problems the founders were running into all the time.
Talos Systems eases the work of deploying and managing bare metal, and running multiple clusters in multiple locations – all while guaranteeing and verifying security and integrity. Real life problems. Solved.
Why the name “Talos”?
Talos was an automaton created by the Greek God of the forge to protect the island of Crete. He would patrol the coast and enforce laws throughout the land. They felt it was a fitting name for a security focused operating system designed to run Kubernetes.
