Limit Range

You can create a LimitRange policy to constrain virtual cluster resource allocation. vCluster creates the LimitRange on the host in the same namespace as vCluster itself. LimitRange only applies to synced resources, such as pods.

Example​

If you would normally deploy the following LimitRange:

apiVersion: v1
kind: LimitRange
metadata:
  name: vcluster-limit-range
spec:
  limits:
  - default:
      memory: 512Mi
      cpu: "1"
    defaultRequest:
      memory: 128Mi
      cpu: 100m
    type: Container

Instead configure the LimitRange in your vcluster.yaml config file like this:

limitRange:
  enabled: true
  default:
    memory: 512Mi
    cpu: "1"
  defaultRequest:
    memory: 128Mi
    cpu: 100m
