Scaling an AKS (Azure Kubernetes Services) cluster explained in plain English

This is the super simplified video animated explanation on everything you ever wanted to know about scaling in the context of an AKS cluster (Azure Kubernetes Services). We will cover the following topics :
1. Manually scale a pod in or our an AKS cluster - how to and demo
2. Automatically scale pod in or out in an AKS cluster using horizontal pod autoscaler (hpa) - how to and demo
3. Manually scale a node in or out an AKS cluster - how to and demo
4. Automatically scale a node in or out an AKS clusters - the gotchas, how to and demo

nicely done. Good job describing the scaling events and timings. I could listen to you instruct on how to make a baloney sandwich!

Before going to automatic scale for worker nodes, we want to install the metric server in the AKS cluster have been, right...?

[@hitmanvivek]

How do i specify limits on a cluster autoscale or how cluster autoscale knows at what condition it should scale

[@cloud-monk]

you can use this to configure granular details for autoscaler configuration docs.microsoft.com/en-us/azure/aks/cluster-autoscaler#using-the-autoscaler-profile

[@JenaTofan]

If you want to configure pod autoscaller , you need to specify the targetCPU utilization in your deployment manifest. And you need create a object kind autoscaller, in this manifest you can specify the minimum pod count and maximium pod count .

@@cloud-monk from reading the doc what I understood is for scale-down, we can use `scale-down-utilization-threshold` , but for scale-up there is no such config, if there are any unschedulable pods then it tries to scale-up, cmiiw

just get to the point.
