Migration to Kata 2.0, and support timeline for 1.x
by Eric Ernst 11 May '21

11 May '21

Hey kata folk -- With 2.0 out now, we are focusing continued development and improvements on the 2.0 code base. As a result, in a prior architecture committee meeting discussion, we made the decision on a 6 month window (from release of 1.12) before stopping regular support of the 1.x (1.11 and 1.12 currently) branches. Based on this, here's a first heads up! We plan to deprecate support for 1.x on May 12th 2021. Thanks! Eric

New groups have been created to help with triage and investigation of CI failures
by Fabiano Fidêncio 30 Nov '20

30 Nov '20

Ahoy Kata citizens, We've created two new groups, one called kata-containers/redhat, and one called kata-containers/power, in order to help triaging, debugging, and solving CI issues. The "power" group should be pinged for CI failures (and other generic questions) related to PowerPC. The "redhat" group should be pinged for CI failures (and other generic questions) that are related to Red Hat products, such as: CentOS, CRI-O, Fedora, OpenShift, Podman, RHEL, VirtioFS. Please, do not hesitate in looping in those groups! Best Regards, -- Fabiano Fidêncio

Adding labels to issues
by Ariel Adam 17 Nov '20

17 Nov '20

Hi everyone. At the kata upstream meeting today we discussed the idea of adding labels to issues for splitting them into categories of expertise. The idea is to use the existing *"area/*"* set of labels with the following values: *area/api, area/cli, area/config, area/documentation, area/logging, area/networking, area/performance, area/storage, area/tracing* Please let us know if you think we should use a different approach or add/remove/modify these categories. Thanks.

kata-agent getting OOM-killed
by Christophe de Dinechin 16 Nov '20

16 Nov '20

Hey team, What are the trade-offs between running agent as init and running it under systemd. There is this interesting bug: https://bugzilla.redhat.com/show_bug.cgi?id=1890681 where the agent gets OOM-killed. That manifests itself with somewhat hard-to-diagnose symptoms. I opened https://github.com/kata-containers/kata-containers/issues/1111. The solution Qian suggested was to set oom_score_adjust. I investigate that. But that made me wonder about the trade-off between using systemd and agent-as-init. Do we have this documented somewhere? Thanks Christophe

Kata Releases 1.12.0 and 1.11.5
by Shinde, Archana M 13 Nov '20

13 Nov '20

Hi All, We released Kata 1.12.0 this week. This release brings in several exciting features including: * Support for getOOMEvent GRPC agent API so OOM events can be retrieved from the agent. * We now detect and support static ARP entries that may be created by a network plugin. * Added support to hotplug block and vfio devices in cloud hypervisor. * Fixes were made to make sure systemd cgroups are detected and handled correctly. * OpenShift CI enabled on runtime repository. * A debug-only capability was added to allow a debug container to run in the agent PID namespace. * Host cpuset support added for cpuset.cpus and cpuset.mems Kata 1.12.0 release also includes following security fixes. Users are highly encouraged to upgrade. * Readonly bind-mounts are now mounted read-only on the host. With this fix, mounts are protected at VM boundary not just the guest kernel. If a container escape were to occur, one would be able to write to a directory or file that was mounted read-only prior to this fix. * Certain annotations in kata can be used to execute pre-exiting binaries. This could be used to execute arbitrary binaries with the onus of validating these paths left to the stack about Kata. In this release, we added appropriate validations so that an admin can configure a list of file system paths that can be used to filter annotations that represent valid file names. Additionally, we made a patch release 1.11.5 with the above security fixes included with additional bug fixes. Please refer to the release notes for more details: https://github.com/kata-containers/runtime/releases Thanks, Archana Shinde
