  • OPNFV Hunter Delivers Test Tools, CI/CD Framework to Enable Common NFVI for Verifying VNFs

    LF Networking (LFN), which facilitates collaboration and operational excellence across open networking projects, today announced the availability of OPNFV ?Hunter,? the platform?s eighth release. Hunter advances OPNFV?s system level integration, deployment, and testing to collaboratively build a common industry Network Functions Virtualization Infrastructure (NFVI) that will reduce Communication Service Provider (CSP) and Virtual Network Function (VNF) vendor efforts to verify VNFs against different NFVI platforms.

    Open Platform for NFV (OPNFV) is a project and community that facilitates a common NFVI, continuous integration (CI) with upstream projects, stand-alone testing toolsets, and a compliance and verification program for industry-wide testing and integration to accelerate the transformation of enterprise and service provider networks.  

    ?The latest OPNFV release sets the stage for a real turning point in the maturity of the platform,? said Heather Kirksey, vice president, Community & Ecosystem Development, the Linux Foundation. ?With continued evolution in areas of testing, verification, and CI/CD, OPNFV is on its way to enable a common NFVI stack that will meet the needs of operators. We are working  in collaboration with both global operators as well as the GSMA, and I am incredibly excited to see the community work to provide the resources needed to accelerate network transformation across the ecosystem.?

  • Glusterfs vs. Ceph: Which Wins the Storage War?

    Storing data at scale isn?t like saving a file on your hard drive. It requires a software manager to keep track of all the bits that make up your company?s files. That?s where distributed storage management packages like Ceph and Gluster come into place.

    Ceph and Gluster are both systems used for managing distributed storage. Both are considered software-defined storage, meaning they?re largely hardware-agnostic. They organize the bits that make up your data using their own underlying infrastructure, which is what defines this choice: what underlying framework do you want supporting your data?

    That?s a decision you want to make based on the type of data you?re storing, how that data is accessed, and where that data lives. Ceph and GlusterFS are both good choices, but their ideal applications are subtly different.

  • Developing Kubernetes API Extensions And Operators - Kubebuilder Vs Operator Kit Vs Metacontroller

    As more teams adopt Kubernetes in production, specific use cases and needs have emerged that build on the core feature set of the project. Rather than attempt to fit every requirement in Kubernetes itself, the community has worked towards building an extension framework to enable developers to build support for these different scenarios. Examples of customizing Kubernetes include configuring different network or storage plugins, restricting what container images can be run inside Pods and other admission policies, or creating API extensions for automating common cluster operations. Let?s take a deeper look at the latter type of extension.

Red Hat's OpenShift and Fedora's Latest

  • Enhanced OpenShift Red Hat AMQ Broker container image for monitoring
    Previously, I blogged about how to enhance your JBoss AMQ 6 container image for production: I explained how to externalise configuration and add Prometheus monitoring. While I already covered the topic well, I had to deal with this topic for version 7.2 of Red Hat AMQ Broker recently, and as things have slightly changed for this new release, I think it deserves an updated blog post! This post is a walk-through on how to enhance the base Red Hat AMQ Broker container image to add monitoring. This time we’ll see how much easier it is to provide customizations, even without writing a new Dockerfile. We will even go a step further by providing a Grafana dashboard sample for visualising the broker metrics.

  • New Style Signal/Slot Connection
    Yes, I know. The last post on the assistants is rather boring. And yet these days I have been working on the snapshot docker, though it still seems a little (just a little, you see) unfinished as Dmitry is said to experience a relatively high delay when switching between snapshots. However this is not what I can reproduce on my older laptop, so I am really waiting for his test results in order to further investigate the problem. But there is something interesting happening just when I am randomly testing things. From Krita’s debug output, I saw QObject::connect() complaining about the arguments I passed, saying it is expecting parenthesis. “Okay,” I thought, “then there have to be something wrong with the code I wrote.” And that was quite confusing. I remember having used member function pointers in those places, got a compile-time error since KisSignalAutoConnectionsStore did not support the new syntax, then switched back to the SINGAL() and SLOT() macros. KisSignalAutoConnectionsStore is a helper class to quickly (dis)connect a group of connections. One can use the addConnection() method to add a connection, and use clear() to remove all connections made before. Well, everything good, apart from the fact that I missed the parenthesis, which I did not discover until I looked into the debug output. So I asked Dmitry why not add the new syntax to KisSignalAutoConnectionsStore, and he said we should.
