Current Series Release Notes¶

New Features¶

• Deploy kubelet in master nodes for the k8s_fedora_atomic driver. Previously it was done only for calico, now kubelet will run in all cases. Really useful, for monitoing the master nodes (eg deploy fluentd) or run the kubernetes control-plance self-hosted.

• Add ‘grafana_tag’ and ‘prometheus_tag’ labels for the k8s_fedora_atomic driver. Grafana defaults to 5.1.5 and Prometheus defaults to v1.8.2.

Deprecation Notes¶

• Currently, Magnum is running periodic tasks to collect k8s cluster metrics to message bus. Unfortunately, it’s collecting pods info only from “default” namespace which makes this function useless. What’s more, even Magnum can get all pods from all namespaces, it doesn’t make much sense to keep this function in Magnum. Because operators only care about the health of cluster nodes. If they want to know the status of pods, they can use heapster or other tools to get that. So the feauture is being deprecated now and will be removed in Stein release. And the default value is changed to False, which means won’t send the metrics.

Bug Fixes¶

• Add a new label service_cluster_ip_range for kubernetes so that user can set the IP range for service portals to avoid conflicts with pod IP range.
