Auto scaling in Kubernetes (Part 2)

Using linkerd for auto scaling
Posted 2021-08-07

In the first part of this post, we visited auto scaling using the metrics server. In part two, we will look at using custom metrics, specifically those from linkerd and ingress-nginx to perform auto scaling based on latency and requests per second.

Using auto scaling in Kubernetes (Part 1)

Taking a look at autoscaling on Kubernetes in practice
Posted 2021-08-07

One of the many useful features within Kubernetes, is the concept of horizontal autoscaling your deployments. In this post, we will take a closer look at how to configure this, and some things to watch out for. This post about auto scaling has been split into 2 parts. The first is about auto scaling using CPU and memory metrics. Part 2 focusses on auto scaling with ingress-nginx and linkerd.

The past few months I’ve heavily invested into learning Kubernetes. So far, I’ve loved every part of it. At work I am constraint at the environments we run our systems in. We’re not able to move to the public cloud for various reasons, and do not have any persistent storage available through an API that can be easily mounted and controlled using a storage plugin / driver.
