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.

You're reading from The DevOps 2.5 Toolkit
Viktor Farcic is a senior consultant at CloudBees, a member of the Docker Captains group, and an author.
He codes using a plethora of languages starting with Pascal (yes, he is old), Basic (before it got the Visual prefix), ASP (before it got the .NET suffix), C, C++, Perl, Python, ASP.NET, Visual Basic, C#, JavaScript, Java, Scala, and so on. He never worked with Fortran. His current favorite is Go.
Viktor's big passions are Microservices, Continuous Deployment, and Test-Driven Development (TDD).
He often speaks at community gatherings and conferences. Viktor wrote Test-Driven Java Development by Packt Publishing, and The DevOps 2.0 Toolkit. His random thoughts and tutorials can be found in his blog—Technology Conversations
