When your Kubernetes fleet can’t drift, upgrades stop being a gamble. (SPONSOR) Kubernetes upgrades have a way of sliding to next quarter, because one drifted node is enough to derail a routine upgrade. Talos Linux is immutable, so every node runs from the same image and can’t drift apart. Talos Omni upgrades the OS and Kubernetes together, one cluster at a time across the fleet, so the upgrade you dreaded turns into a non-event. 93% of teams have already hit an AI-caused infrastructure incident, but only 30% have a policy. Spacelift surveyed 406 leaders on who’s actually ready for AI. Download the report to see what the most advanced teams do differently, and watch the event where we unpacked the data. (SPONSOR) Building a Custom Metrics Exporter for Kubernetes (8 minute read) A hands-on tutorial for writing your own Prometheus exporter in Go, packaging it as a container, and wiring it into a cluster so you can autoscale on real signals like queue depth instead of just CPU and memory. Counters, gauges, histograms, naming conventions, and HorizontalPodAutoscaler integration, all in one walkthrough. ...

With Talos, most CVEs never apply, and patching the rest won’t break the fleet. Patching a CVE means knowing whether it applies to you, then getting the fix to every node without missing one. Talos Linux ships fewer than 50 binaries, because that’s all it takes to run Kubernetes, so most CVEs never apply. Omni rolls out the ones that do, staged and health-checked, with automatic rollback if a node fails. Designing IaC Interfaces That Work for Humans, AI Agents, and Whatever Comes Next (SPONSOR) AI agents are changing who, or what, uses your Terraform modules. Join Jinger Meilani, Senior DevOps Engineer at MNTN, to learn how to design reusable, self-service IaC interfaces that reduce misuse and work for humans, AI agents, and whatever comes next. Announcing etcd v3.7.0 (11 minute read) SIG etcd ships v3.7.0 with a new RangeStream API for streaming large result sets, keys-only range and faster lease optimizations, plus removal of the legacy v2 store. The quiet workhorse under every Kubernetes cluster gets a meaningful tune-up. ...
