"Sidero Labs has been developing Talos Linux, an immutable operating system purpose-built exclusively for running Kubernetes, alongside Omni, a cluster lifecycle management platform. InfoQ met the Sidero team in Amsterdam during the TalosCon 2025 and had conversations about their approach to simplifying Kubernetes operations through minimalism and security-first design. The concept for Talos emerged from practical frustrations with traditional operating systems in enterprise environments."
"The team explained their philosophy: We kind of just landed on the idea that we shouldn't have to care about the operating system at all when it comes to all we want to do is run Kubernetes anyways. The idea of it being immutable kind of came out of that and just being the less stuff that can change, the less things that can go wrong."
Sidero Labs develops Talos Linux, an immutable operating system purpose-built exclusively for running Kubernetes, and Omni, a cluster lifecycle management platform. Practical frustrations with traditional enterprise operating systems and lengthy annual security audits led to the conclusion that teams should not manage full OS complexity when their goal is running Kubernetes. Talos minimizes surface area by stripping userland to just enough functionality to run the kubelet and rewriting userland in Go, increasing reliability and reducing unexpected failures. Talos provides vanilla upstream Kubernetes with full conformance testing on each release while making opinionated deployment choices beneath the Kubernetes layer. System extensions enable customized Talos variants while preserving user control over clusters.
