Hi all,
Now we're very close to the milestone-2 of Train release. I'd like to take this opportunity to update the project status of Magnum.
So far, we have done some great work in this cycle which make Magnum to achieve to a higher level. The first feature I'd like to highlight is the k8s version rolling upgrade. With this feature, user can upgrade their k8s version with zero downtime for their application. Another one is auto scaling, now Magnum can support k8s cluster auto scaling by leveraging the Cluster Autoscaler (there is a OpenStack Magnum driver contributed by CERN team). Besides, Magnum now can support auto repair, aka auto healing, by using a combination of Draino, Cluster Autoscaler and Node Problem Detector.
Except above work we have done, there are still a lot of cool features coming:
1. The first one I'd like to mention is the boot volume support. With this feature, user can boot k8s cluster node from volume and user can even set the volume type which is super useful if the cloud provider can support high performance storage, e.g. NVME. And a new useful label named "etcd_volume_type" will be introduced by the way so that user can set the volume type for etcd volume to get a great performance for etcd cluster.
2. Private cluster. With this feature, user can set the network, subnet and floating IP when creating cluster with a public cluster template, which is very handy when user want to use public templates but still want to create the cluster in their existing network.
3. Another super fancy feature is introducing a new auto healing controller except the Draino+CA+NPD combination. Recently, we (Catalyst Cloud) contributed our Magnum auto healer[1] to Cloud-Provider-Openstack repo and we're trying to introduce it to Magnum as another auto healing controller, it would be also very useful for end user to get a zero downtime k8s cluster.
As you can see, there are quite a lot of exciting features are being introduced into Magnum, however all of them are done by such a small team. What a cool team! As you know, Kubernetes is still evolving very fast, so we're very keen to get more help from the community. We're working hard to add some new core members to our existing team, but we do need more.
In short, if you're interested in provisioning Kubernetes on OpenStack, please try Magnum and feel free to pop up on #openstack-containers for any question. Cheers.
