Talos System OS v0.5, the advanced Kubernetes operating system, has just been launched and they’re excited to share the new features they’ve added. Talos Systems: Secure, Stable Kubernetes everywhere to host Kubernetes clusters, and running a flexible and powerful API-driven OS for kubernetes. Their page is talos-systems/talos is a modern OS for Kubernetes.
Now, lets walk you through a Guide to best Linux Operating Systems for Kubernetes. But, while you read about the Kubernetes operating system, move on to look up this Container 101 Tutorial on Kubernetes for Beginners and MasterClass.
They (Talos systems) also added three new big APIs to this version of Talos: control plane recovery, control plane bootstrapping, and a new event subsystem that can be used at the OS level for sophisticated automation.
We have refactored the init framework as part of this update, which has made it much simpler to introduce new APIs.
The risk of losing the control plane is an inherent risk in operating a self-hosted control plane. I’m not going to go into the specifics of a self-hosted control plane here, but we have included an API to recover a lost control plane in this release of Talos. Configure talosctl to point at any control plane node to recover the control plane and execute:
It is as easy as that. We have found it incredibly difficult in practice to get into a condition that would require recovery, but if you need to, the control plane can be easily recovered.
They had to depend on the configuration file in areas where we would eventually like to see an API, as they have developed the foundation of their next generation OS.
The bootstrap API eliminates the need for a specific form of configuration to be handled for bootstrapping of etcd and Kubernetes.
In update and recovery situations, this special configuration requires careful handling, and can present edge cases that enable the user to be aware of implementation specifics.
Talos aim is to automate all these processes so that the node becomes less and less of a “thing” that you have to handle, and gradually fades into the background. The bootstrap API takes users away from configuration management and in the direction of a higher degree of automation.
Spin up any number of control planes to bootstrap a cluster and execute the following against any of them:
The cluster will be bootstrapped and ready for workloads within just a few minutes.
To reiterate, Talos goal is to bring about an unparalleled level of automation at the level of the host OS. A great example of the ways they work to link low-level operating system functionality into a modern API is the latest Events API.
Events at the level of the operating system open up some very fascinating opportunities that have not been really explored. Therefore, imagine having access to network events such as configuration updates, security events, or boot development, programmatically and automation-driven.
However, based on these new APIs, we are very excited about the possibilities for interesting features. For a more stable update controller, they say that they already have plans to use events.
We plan to extend the Events API in the future, so that the list of features can be dynamically extended, and so that Talos users can publish events without any help. According to them, they’d love your feedback on what kinds of activities at the OS level you’d like to see. So, you can help them form what the Linux distributions of the next generation look like, and let them know via their website!
For this update, Talos put in some work that should make navigating documentation much simpler.
The Path to 1.0
You may have observed that this update arrived sooner than previous releases after 0.4. They’ve changed their model and are now going to introduce new versions of Talos more frequently. Their previous cycle lasted approximately 12 weeks, and the current cycle will last 6 weeks. This will encourage everyone to iterate more quickly and get their users latest features out quicker.
Notice that, in this version of Talos, the APIs released are still called alpha. It can break stuff, and the API is subject to change.
The organization plans to see an increased pace of added functionality beyond the basics they have been working on for so long with some of the work completed in this release of Talos. While Talos is ready for development, it is not complete, and they promise to concentrate on getting to something that they believe is worth calling 1.0 this year.
Talos 0.4, v0.5, v0,6, v0.7 Released!

About Talos Organization
Talos was born from the experience of Kubernetes in real life and from real life problems. For a few years, the founders worked with K8s, operating production clusters for SaaS businesses that needed operational stability and protection.
A variety of tools were needed to run K8s on a general purpose OS such as RHEL or Ubuntu to ensure stability, and regular patching and OS updates to fix bugs in the underlying operating system and packages. Fragility was introduced into the system by these operational headaches.
To solve this, Talos Systems was born. A fundamentally new system of service, designed specifically for Kubernetes.
Talos OS is not an operating system for general purposes; it is minimal, hardened, and immutable. Additionally, this removes security vulnerabilities, which makes it much simpler to update and switch from one environment to another.
The Talos platform automates K8s out of the box for installation and security. In short, it addresses the problems of the modern world the founders have been running into all the time.
In conclusion, Talos Systems makes it simple to deploy and manage bare metal and operate multiple clusters in multiple locations, all while maintaining protection and integrity and checking them. Finally, they solve true issues with life. Solved. Resolved.
