Want to get more done with OpenStack? We've got you covered.
We've put together some of the best how-tos, guides, tutorials, and tips published over the past month into this handy collection. And if you need more help, the official documentation for OpenStack is always a great place to turn.
- Our first guide this month takes you through, in two parts, how to configure guest CPU topology in OpenStack. A new feature of the Juno release, CPU topology essentially allows you to express the sockets, cores per socket, and threads per core that each guest virtual machine has access to.
- Up next, a look at some considerations when splitting a Swift cluster. In order to replicate data across multiple locations, you'll want to proceed carefully to prepare properly, monitor the transfer, ensure date integrity, and limit the amount of data to be moved.
- Tim Bell takes us through some of the steps taken at CERN to allow for single sign-on through Kerberos within OpenStack, a feature which will hopefully make it to upstream OpenStack soon.
- Container orchestration and management have been a hot topic for a while now, and Kubernetes is one potential solution. Here's a look at how to set up a Kubernetes cluster on OpenStack with Heat.
- When working with OpenStack, sometimes the IP address of individual nodes change for a variety of reasons; how do you get OpenStack to recognize these changes? Symantec has a quick guide to changing the endpoint IP addresses after OpenStack installation with DevStack.
- While there are lots of reasons you might want to put two virtual instances on the same host, perhaps for speeding up communications, there are plenty of reasons for separating them as well, like resiliency. Since Icehouse, OpenStack has had affinity and anti-affinity controls for enforcing these policies. Here's how to use them.
- Do you wish that allowing users to create public images in Glance was easy? Turns out, it is! Just a quick configuration change and a restart will get you going.
- Our final tip is a little trick for OpenStack developers who are on the road with less-than-ideal internet connections which only allow traffic along a few ports. Aaron Rosen found himself in the situation, and found a way to still be able to push patches to Gerrit over https. It's incredibly simple, but undoubtedly will make someone's life easier.
That's it for this month. Check out our past OpenStack tutorials collection for more great guides and hints. And if we missed your favorite new guide or resource, let us know in the comments!
