Introducing LimitRange

LimitRange is another object that is similar to ResourceQuota as it is created at the namespace level. The LimitRange object is used to enforce default requests and limit values to individual containers. Even by using the ResourceQuota object, you could create one object that consumes all the available resources in the namespace, so the LimitRange object is here to prevent you from creating too small or too large containers within a namespace.

Here is a YAML file that will create LimitRange:

# ~/limitrange.yaml
apiVersion: v1
kind: LimitRange
metadata:
  name: my-limitrange
spec: 
  limits:
  - default:
      memory: 256Mi
      cpu: 500m
    defaultRequest:
      memory: 128Mi
      cpu: 250Mib
    max:
      memory: 1000Mi
