Study the different kinds of autoscaling in Kubernetes: Pod, Cluster, DNS Service, other? Do we have the right topics? Are they positioned correctly in the table of contents? Should topics on the different kinds of autoscaling be isolated from each other, or should the be part of a coherent set? Put all autoscaling topics into the appropriate templates: Concept, Task, or Tutorial. Edit to comply with our style guide. Check for accuracy. Here are some of the existing topics:
Horizontal Pod Autoscaling Walkthrough
Horizontal Pod Autoscaling
Autoscale the DNS Service in a Cluster
Cluster Management
