Resource quota

You can control vCluster resource consumption by configuring a ResourceQuota. vCluster creates the ResourceQuota in the same namespace as vCluster itself. Resource quotas apply to all resources synced to the host cluster.

Example

If you would normally deploy the following ResourceQuota:

apiVersion: v1
  kind: ResourceQuota
  metadata:
    name: pods-medium
  spec:
    hard:
      cpu: "10"
      memory: 20Gi
      pods: "10"
    scopeSelector:
      matchExpressions:
      - operator : In
        scopeName: PriorityClass
        values: ["medium"]

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

policies:
  resourceQuota:
    enabled: true
    quota:
      cpu: "10"
      memory: 20Gi
      pods: "10"
    scopeSelector:
      matchExpressions:
        - operator : In
          scopeName: PriorityClass
          values: ["medium"]

Config reference

resourceQuota required object

ResourceQuota specifies resource quota options.

enabled required string|boolean auto

Enabled defines if the resource quota should be enabled. "auto" means that if limitRange is enabled, the resourceQuota will be enabled as well.

quota required object map[count/configmaps:100 count/endpoints:40 count/persistentvolumeclaims:20 count/pods:20 count/secrets:100 count/services:20 limits.cpu:20 limits.ephemeral-storage:160Gi limits.memory:40Gi requests.cpu:10 requests.ephemeral-storage:60Gi requests.memory:20Gi requests.storage:100Gi services.loadbalancers:1 services.nodeports:0]

Quota are the quota options

scopeSelector required object map[matchExpressions:[]]

ScopeSelector is the resource quota scope selector

scopes required string[] []

Scopes are the resource quota scopes

annotations required object {}

Annotations are extra annotations for this resource.

labels required object {}
