Limit range

Supported Configurations

Running the control plane as a container with:

• Shared Nodes

You can create a LimitRange policy to constrain tenant 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:

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

Config reference

limitRange object

LimitRange specifies limit range options.

enabled string|boolean auto

Enabled defines if the limit range should be deployed by vCluster. "auto" means that if resourceQuota is enabled, the limitRange will be enabled as well.

default object map[cpu:1 ephemeral-storage:8Gi memory:512Mi]

Default are the default limits for the limit range

defaultRequest object map[cpu:100m ephemeral-storage:3Gi memory:128Mi]

DefaultRequest are the default request options for the limit range

max object {}

Max are the max limits for the limit range

min object {}

Min are the min limits for the limit range

annotations object {}

Annotations are extra annotations for this resource.

labels object {}

Labels are extra labels for this resource.
