SIGTERM Doesn’t Mean Stop, Reject Any Service Without O11y, GKE IP exhaustion fixed, Istio- MultiCluster MultiPrimary MultiNetwork
This newsletter is brought to you by LearnKube — build GPU platforms on Kubernetes. Learn GPU sharing, isolation, and efficiency through private, hands-on training for your team.
Hi, Dan here!
We launched a new private, instructor-led course: Building GPU Platforms on Kubernetes!
In the past 2 years, I wrote 2 books on running GPUs on Kubernetes (you can find them here). This work is now part of a four-day, hands-on course for platform engineers.
It covers how GPUs reach containers, how time-slicing and MIG differ, and how to tell GPU allocation from useful work.
You can find the full agenda here!

This tutorial teaches how to use CronJobs, RBAC, ServiceAccounts, and the Go client-go library by building a three-cronjob system that dynamically adjusts Philips Hue light schedules based on daily sunrise/sunset forecasts from OpenWeatherMap.
Your CI Pipeline Should Reject Any Service Without an Observability Contract

This case study shows how a silent 47-minute outage pushed one team to block merges in CI with an OPA policy that rejects any service without proper observability settings.
Building GPU Platforms on Kubernetes
Your GPUs are allocated. Are they doing useful work?
Our four-day private course combines Kubernetes fundamentals with hands-on GPU labs.
