Resource Allocation

Steps to Configure Overrides

To apply custom resource allocations for system applications like the rafay-connector, follow the steps below:

Step 1: Create an Override Using rctl

./rctl create cluster-override -f <override.yamlfile>

Example of v3 override yaml file (Recommended)

apiVersion: infra.k8smgmt.io/v3
kind: AddonOverride
metadata:
  labels:
    rafay.dev/overrideScope: clusterLabels
    rafay.dev/overrideType: valuesFile
  name: connector-override
  project: defaultproject
spec:
  placement:
    labels:
    - key: rafay.dev/clusterName
      value: cluster-1
  resource:
    selector:
      selector: rafay.dev/system=true,rafay.dev/component=v2-infra
    type: Addon
  type: Helm
  valuesPath:
    name: file://connector_override_values.yaml

File named connector_override_values.yaml with the following content to specify the resource requests and limits:

connector:
  resources:
    requests:
      cpu: 100m
      memory: 128Mi
    limits:
      memory: 1024Mi
      cpu: 1000m

• resourceSelector must remain unchanged, as it targets values in v2-infra for override
• clusterSelector can include any label key-value pair, for example: venus=flytrap

Example of v2 override yaml file (Deprecated)

kind: ClusterOverride
apiVersion: config.rafay.dev/v2
metadata:
  name: connector-override
spec:
  clusterSelector: venus=flytrap
  resourceSelector: rafay.dev/system=true,rafay.dev/component=v2-infra
  type: ClusterOverrideTypeAddon
  overrideValues: |
    connector:
      resources:
        requests:
          cpu: 100m
          memory: 128Mi
        limits:
          memory: 1024Mi
          cpu: 1000m
  clusterPlacement:
    placementType: ClusterSelector
    clusterSelector: venus=flytrap
    driftAction: DriftReconcillationActionNotSet
    clusterLabels: []

Step 2: Republish the blueprint

• The v2-infra add-on should succeed and apply the updated resource values.

Note: It is not necessary to provide all the overrideValues parameters.

For a list of resource override specifications for other system applications, refer to the Override Examples.
