Resource quota

Limited vCluster Tenancy Configuration Support

This feature is only available when using the following worker node types:

Host Nodes

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"]
