koptimize

Helm chart for koptimize. Note, that while the Helm chart is open source and the Docker image is public, the code for koptimize itself is private.

koptimize aims at reducing cost of a Kubernetes cluster, going further than, for example, the cluster autoscaler.

Features

• A mutating webhook, that forces workloads (that tolerate spot instances) onto spot instances. This is helpful, to ramp up spot instance usage. Example:

apiVersion: v1
kind: Pod
metadata:
  name: my-pod
  namespace: default
spec:
  ...
  tolerations:
    - key: cloud.google.com/gke-spot
      operator: Equal
      value: "true"
      effect: NoSchedule

becomes

apiVersion: v1
kind: Pod
metadata:
  name: my-pod
  namespace: default
spec:
  ...
  affinity:
    nodeAffinity:
      requiredDuringSchedulingIgnoredDuringExecution:
        nodeSelectorTerms:
          - matchExpressions:
              - key: cloud.google.com/gke-spot
                operator: In
                values:
                  - "true"
  tolerations:
    - key: cloud.google.com/gke-spot
      operator: Equal
      value: "true"
      effect: NoSchedule
