Please note that we used autoscaling/v2beta1 version of HorizontalPodAutoscaler. At the time of this writing (November 2018), only v1 is stable and production-ready. However, v1 is so limited (it can use only CPU metrics) that it's almost useless. Kubernetes community worked on new (v2) HPA for a while and, in my experience, it works reasonably well. The main problem is not stability but potential changes in the API that might not be backward compatible. A short while ago, autoscaling/v2beta2 was released, and it uses a different API. I did not include it in the book because (at the time of this writing) most Kubernetes clusters do not yet support it. If you're running Kubernetes 1.11+, you might want to switch to v2beta2. If you do so, remember that you'll need to make a few changes to the HPA definitions we explored. The logic is still the same, and...

Overview of this book
Building on The DevOps 2.3 Toolkit: Kubernetes, and The DevOps 2.4 Toolkit: Continuous Deployment to Kubernetes, Viktor Farcic brings his latest exploration of the Docker technology as he records his journey to monitoring, logging, and autoscaling Kubernetes.
The DevOps 2.5 Toolkit: Monitoring, Logging, and Auto-Scaling Kubernetes: Making Resilient, Self-Adaptive, And Autonomous Kubernetes Clusters is the latest book in Viktor Farcic’s series that helps you build a full DevOps Toolkit. This book helps readers develop the necessary skillsets needed to be able to operate Kubernetes clusters, with a focus on metrics gathering and alerting with the goal of making clusters and applications inside them autonomous through self-healing and self-adaptation.
Work with Viktor and dive into the creation of self-adaptive and self-healing systems within Kubernetes.
