9.2.0 ^^^^^
New Features ************
* Added label heapster_enabled to control heapster installation in the cluster.
* Installs the metrics-server service that is replacing kubernetes deprecated heapster as a cluster wide metrics reporting service used by schedulling, HPA and others. This service is installed and configured using helm and so tiller_enabled flag must be True. The label metrics_server_chart_tag can be used to specify the stable /metrics-server chart tag to be used. The label metrics_server_enabled is used to enable disable the installation of the metrics server (default: true).
* Added custom.metrics.k8s.io API installer by means of stable /prometheus-adapter helm chart. The label prometheus_adapter_enabled (default: true) controls configuration. You can also use prometheus_adapter_chart_tag to select helm chart version, and prometheus_adapter_configmap if you would like to setup your own metrics (specifying this other than default overwrites default configurations). This feature requires the usage of label monitoring_enabled=true.
Upgrade Notes *************
* nginx-ingress-controller QoS changed from Guaranteed to Burstable. Priority class 'system-cluster-critical' or higher for nginx- ingress-controller.
Bug Fixes *********
* A regression issue about downloading images has been fixed. Now both Fedora Atomic driver and Fedora CoreOS driver can support using proxy in template to create cluster.
* nginx-ingress-controller requests.memory increased to 256MiB. This is a result of tests that showed the pod getting oom killed by the node on a relatively generic use case.
* k8s-keystone-auth now uses the upstream k8scloudprovider docker repo instead of the openstackmagnum repo.
* Fixes the next url in the list nodegroups API response.
* Bump up prometheus operator chart version to 8.2.2 so that it is compatible with k8s 1.16.x.
* Bump up traefik to 1.7.19 for compatibility with Kubernetes 1.16.x.
