Kata releases 1.11.0-alpha0, 1.10.1 and 1.9.5 available
by Shinde, Archana M 26 Feb '20

26 Feb '20

Hi All, Kata alpha release 1.11.0-alpha0 is out. With this alpha release, we introduced several features including support for kernel stable version 5.4.15. We added support for ipv6 with integration tests added to verify ipv6 with Docker. The "newstore" feature has been an experimental feature for a long time. This feature has now transitioned to a formal feature. The newstore feature guarantees better compatibility between different versions of Kata components. We now support Firecracker version 0.20.0 and Cloud Hypervisor v0.5.x stable branch with this release. Several improvements were made for rootless support including fixing rootless for net=none, leveraging the libcontainer API for rootless functionalities and supporting "--rootless" runtime flag. Stable releases 1.10.1 and 1.9.5 are also available now. Thanks, Archana

kata in non-baremetal environments
by Ralf Haferkamp 14 Feb '20

14 Feb '20

Hi, it seems that nowadays a large chunk of k8s deployments being run in virtualized enviroments (i.e. some form of public/private IaaS system). So using kata-containers in such an enviroment means that the VMs spawned by kata are running nested inside the VMs of the k8s cluster. Given that nested virtualization adds quite a bit of overhead (in certain cases I believe) and that it still seems to be considered experimental [0]. Is that really the way to go or is kata-containers really more just aiming for baremetal k8s deployments? regards, Ralf [0] https://www.linux-kvm.org/page/Nested_Guests

Training session on Bitergia dashboard, Feb 17
by Thierry Carrez 13 Feb '20

13 Feb '20

Hi Kata-kats, Since last year, the Kata Containers community dashboard is available at katacontainers.biterg.io. It shows a series of pre-defined dashboards that let you extract metrics from GitHub, git and ML data. However the real power of the Bitergia toolkit is when you go to the next level and drill down and filter for more relevant data, or when you build your own analysis and visualization. In order to present those features and answer community questions, we've set up a video training session with Bitergia which will happen on Jitsi Meet[1] Monday, February 17 at 1600 UTC[2]. Please sign up on: https://etherpad.openstack.org/p/bitergia-training-Feb2020 All details for connection will be posted there. Also if you have examples of changes in existing dashboards that you'd like to see, or of visualizations you'd like to build, please add to the suggestions in the etherpad. We'll collect suggestions to build the final training contents. See you there!

Kata Architecture Committee candidacy for Xu Wang
by Xu Wang 12 Feb '20

12 Feb '20

Name: Xu Wang Email: xu(a)hyper.sh, gnawux(a)antfin.com Background: I am a senior staff engineer of Ant Financial, a related company of Alibaba Group (BABA). I am leading the secure container development team in Ant Financial currently and working for the Cloud-Native open-source of Alibaba as a member of the Ali Open Source TOC. Our team has been working on not only contributing upstream, but also deploying Kata Containers in the productions since we joined Ant Financial. Before joining Ant Financial, Our team, the hyper.sh, had been kept contributing to Kata Containers and related communities since day 0 of Kata. It was my great honor to involve the creating of the Kata Containers project and became an initial member of the Architecture Committee together with Samual Ortiz. In the past months, we celebrated the two year anniversary of Kata. Look back at the past two years, we have improved the isolation in the container world at the expense of some overhead. We believe the container world needs a better isolation solution without hurts on the application-centric nature of Cloud-Native. In 2020, I expect we could developing the virtualization technologies for Cloud Native in the 2.0 development cycle. -- Xu Wang (@gnawux) Senior Staff Engineer at Ant Financial A Member of Kata Containers Architecture Committee

Kata Architecture Committee candidacy for Samuel Ortiz
by Samuel Ortiz 11 Feb '20

11 Feb '20

Name: Samuel Ortiz Email: sameo(a)linux.intel.com Background: I am a Principal Software Engineer working for Intel, where I work on several projects related to virtualization and containers: Kata Containers, rust-vmm and Cloud Hypervisor. My journey with the Kata Containers project started back when I initially lead the Clear Containers project at Intel, a few years ago. Since then I have contributed to many different areas of the project, from core components like the virtcontainers package to integration work with the CRI-O and containerd projects. I was part of the initial Clear Container and RunV engineering efforts to merge the two projects and have been on the Kata Containers Architecture Committee since then. Over the past few months we've seen Kata Containers being deployed in several very large production environments, showing how strong and scalable the project has become. Such large deployments also bring new requirements for security, density and performance that we, as a community, need to look at and meet. I believe this can only be achieved with Kata supporting new security models and virtualization technologies, losing a few abstraction layers and features, and being more tightly integrated with the Cloud Native ecosystem. This is what I want to help push through Kata Containers 2.0, and this is why I'd like to renew my seat on the Kata Architecture Committee. Samuel.

Kata Containers byline: help us out!
by Robert Cathey 08 Feb '20

08 Feb '20

Hi everyone. I'm working on a byline article about Kata to pitch to a publication like The New Stack or ZDNet. It'll be about the status of Kata Containers and where the project is headed next (in very general terms). Our game plan is to start with existing source material like the white paper <https://katacontainers.io/collateral/ApplicationOfKataContainersInBaiduAICl…> and Medium blog <https://medium.com/kata-containers/kata-baidu-whitepaper-16ad04a5302>. We'd love to get input from the AC or anyone else in the community, including quotes and answering a question or two that we might have. If you're interested in collaborating, just raise your hand. We'll be working on the draft over the next couple of weeks. NOTE: We don't necessarily need you to be quoted or attributed if that's problematic for you or your organization. Thanks! -- *Robert Cathey* Cathey.co <http://cathey.co/> +1 865-386-6118 @robertcathey <http://www.twitter.com/robertcathey>

Elections for Kata Architecture Committee: Dave Gilbert
by Dr. David Alan Gilbert 05 Feb '20

05 Feb '20

Name: David Alan Gilbert Email: dgilbert(a)redhat.com Introduction: I'm a Principal Software Engineer working for Red Hat in our virtualization team. I've been working on QEMU for the past 6 years, mostly in live migration but more recently working on the virtiofs project. I'm a QEMU maintainer for live migration, virtiofs and the HMP monitor. My previous work with Kata has mainly been in relation to virtiofs and helping debug CI issues on Red Hat/CentOS and Fedora. My primary interest is ensuring that hypervisors (QEMU included) provide the necessary features to enable Kata to operate securely and efficiently. I'm keen to understand the real-world uses of Kata, how virtiofs is used in practice and resolving any usage difficulties in those deployments. I look forward to promoting the wider usage of Kata and pushing its usage in the general enterprise and more specialist areas such as telecommunication systems.

Firecracker deprecation of API call
by Catangiu, Adrian Costin 22 Jan '20

22 Jan '20

Hi kata, I’m sending this email as a heads-up that we plan to deprecate the “BlockDeviceRescan” API action<https://github.com/firecracker-microvm/firecracker/blob/ebc15f2eacaa4c26782…> in the next Firecracker release. The block device rescan already happens as part of patching a block device with a new host file path, so this API call is redundant. Looking at your code, I see that you’re only using it here<https://github.com/kata-containers/runtime/blob/c3629d37c412a97bd8704ea28d6…> after patching a drive path. You should simply remove that block of code since Firecracker already internally initiates a rescan on the patched block device if there is a guest running. Please let me know if you have other use-cases for the `BlockDeviceRescan` action that I have missed, or any other concerns. Thanks, Adrian. Amazon Development Center (Romania) S.R.L. registered office: 27A Sf. Lazar Street, UBC5, floor 2, Iasi, Iasi County, 700045, Romania. Registered in Romania. Registration number J22/2621/2005.
