In my previous article I discussed Resource Quotas and gave an example of how and why someone may want to consider using them on their cluster. You might have be thinking to yourself in the last article “Well that’s nice you can limit a namespaces resources but what happens if someone creates a pod that just takes it all up at once?”. Well that’s where Limit Ranges come into play.
Limit Ranges in K8s are similar in concept to Resource Quotas in the sense that they are objects and they are used specifically to control resources within namespaces. Limit Range objects purpose is to power you up with the ability to control how resources are consumed by other resources such as pods, containers and even though I have not discussed it in these articles, storage requests.
