v0.11.0

[v0.11.0] - 2022-07-23

Changed

• See the migration guide from v0.10.0 here.
• BREAKING CHANGE: Major rewrite converting this project from a Custom Pod Autoscaler to have its own dedicated CRD
  and operator.
  • Configuration and deployment has changed completely, no longer need to install the Custom Pod Autoscaler Operator,
    instead you need to install the Predictive Horizontal Pod Autoscaler as an operator.
  • No longer deployed as CustomPodAutoscaler custom resources, now deployed as PredictiveHorizontalPodAutoscaler
    custom resources.
• BREAKING CHANGES: Several configuration options renamed for clarity.
  • LinearModel -> storedValues renamed to LinearModel -> historySize
  • Model -> perInterval renamed to Model -> perSyncPeriod
• BREAKING CHANGES: perSyncPeriod behaviour changed slightly, now it will no longer calculate the prediction, but
  it will still update the replica history available to make a prediction with and prune the replica history if needed.
• Holt-Winters runtime hooks format changed:
  • evaluations renamed to replicaHistory.
  • Format change for replicaHistory, now in the format [{"time": "<timestamp>", "replicas": <replica count>}].
• Upgrade to Go v1.18.
• No longer SQLite based storage, instead using Kubernetes configmaps which give persistent storage by default with
  resiliency when the autoscaler operator restarts.
