Spotlight on OpenStack Stein

Congrats to the 1,400 contributors from more than 150 organizations that contributed to Stein, the 19th release of OpenStack that launched this week!

Check out a full list of features and contributors and download the OpenStack Stein release here.

Among the dozens of enhancements in Stein, highlights include:

Delivering core functionality for Kubernetes users

Kubernetes is the number one container orchestration framework running on OpenStack, with 61% of OpenStack deployments indicating they integrate the two platforms, according to the 2018 OpenStack User Survey.

In Stein, OpenStack continues to deliver the core infrastructure management features delivering the bare metal and network functionality that containers need:

  • OpenStack Magnum, a Certified Kubernetes installer, improved Kubernetes cluster launch time significantly—down from 10-12 minutes per node to five minutes regardless of the number of nodes.
  • With the OpenStack cloud provider, you can now launch a fully integrated Kubernetes cluster with support from the Manila, Cinder and Keystone services to take full advantage of the OpenStack cloud it’s created on.
  • Neutron, OpenStack’s networking service, has faster bulk port creation, targeting container use cases, where ports are created in groups.
  • Ironic, the bare metal provisioning service, continues to improve deployment templates for standalone users to request allocations of bare metal nodes and submit configuration data as opposed to pre-formed configuration drives.

Networking enhancements for 5G, edge computing and NFV use cases

  • Within Neutron, Network Segment Range Management enables cloud administrators to manage segment type ranges dynamically via a new API extension, as opposed to the previous approach of editing configuration files. This feature benefits StarlingX and edge use cases, where ease of management is critical.
  • For network-heavy applications, it is crucial to have a minimum amount of network bandwidth available. Work began during the Rocky cycle to provide scheduling based on minimum bandwidth requirements, and the feature was delivered in Stein. As part of the enhancements, Neutron treats bandwidth as a resource and works with the OpenStack Nova compute service to schedule the instance to a host where the requested amount is available.
  • API improvements boost flexibility, adding support for aliases to Quality of Service (QoS) policy rules that enable callers to execute the requests to delete, show and update QoS rules more efficiently.
