This is the story of how we upgraded our fleet of 1200+ MySQL hosts to 8.0. Upgrading the fleet with no impact to our Service Level Objectives (SLO) was no small feat–planning, testing and the upgrade itself took over a year and collaboration across multiple teams within GitHub.

https://questdb.io/blog/questdb-cloud-kubernetes-operator/

The article from QuestDB discusses their transition to a Kubernetes Operator for their cloud operations. The switch involves moving from a provisioner-based system to a Kubernetes Operator, which manages complex operations and orchestrates features like automatic node failure recovery, High Availability, and Cold Storage. This new system simplifies provisioning by reducing code complexity and improving unit testing. It also offers benefits like auto-healing, easier upgrades, and improved control plane locality. The operator is designed to be a drop-in replacement for their current system, ensuring seamless transition and enhanced automation capabilities.

https://povilasv.me/how-to-monitor-kubelet/

The article on Povilas Versockas' blog provides a comprehensive guide on monitoring Kubelet, a key component in Kubernetes. It explains Kubelet's role in managing pods and nodes, details its operation, and discusses how to monitor it effectively using methods like the RED approach. The article also outlines the Kubernetes Service Level Objectives for Kubelet and introduces the Kubernetes Monitoring Mixin, which includes a dashboard and alerts for monitoring Kubelet. This resource is particularly useful for those looking to understand and improve their monitoring of Kubelet in a Kubernetes environment.

Define sleep & wake up cycles for your Kubernetes resources. Automatically schedule to shutdown Deployments, CronJobs, StatefulSets and HorizontalPodAutoscalers that occupy resources in your cluster and wake them up only when you need them, reducing that way the overall power consumption.
