Vertical Pod Autoscaler

Giant Swarm offers a Vertical Pod Autoscaler managed app which can be installed in workload clusters. Here we define the chart with its templates and default configuration.

Additional reading can be found in our public documentation.

Example

You can create a VerticalPodAutoscaler resource that will monitor and update other resources in the same namespace:

apiVersion: autoscaling.k8s.io/v1
kind: VerticalPodAutoscaler
metadata:
  name: fluent-logshipping
  namespace: monitoring
spec:
  targetRef:
    apiVersion: apps/v1
    kind: DaemonSet
    name: fluent-logshipping
  resourcePolicy:
    containerPolicies:
    - containerName: fluent-bit
      controlledResources:
      - memory
      mode: Auto
      minAllowed:
        memory: 100Mi
      maxAllowed:
        memory: 500Mi
  updatePolicy:
    updateMode: Auto

This will look for fluent-bit containers of the fluent-logshipping DaemonSet and manage their memory requests. It will automatically adjust it between 100Mi and 500Mi.
