Version 0.7.1

Controller and Applier

Added

• Support for reducing the resources used by a cluster

  If you have many applications (for example, upwards of a couple hundred) and apply recommendations conservatively (for example, every few days), you can set FF_PATCHER="true" in the extraEnvVar section of your Helm chart. This consolidates and simplifies the cluster component stack and does not negatively affect cluster performance.

• Support for persisting patches to ConfigMaps

  When you set FF_PATCHER="true", you can now have the Controller write a patch to a ConfigMap by setting FF_PERSIST_PATCH="true". Writing a patch to a ConfigMap is useful for troubleshooting cluster resource use.

• Improved HPA logging

  If no HPA targets are discovered, this information is now logged at the info level. Previously, it was logged at the error level.

Workaround

• No recommendations in an HPA setup

  In some HPA setups, the Recommender might not discover HPA targets and therefore cannot generate recommendations. Sometimes this scenario occurs because the Kubernetes version and kube-state-metrics version are not compatible.

  Workaround: Try downgrading your kube-state-metrics version.
