Spotlight on…Kata Containers turns one!

Kata Containers is an open source pilot project supported by the OpenStack Foundation. The Kata Containers community is building a standard implementation of extremely lightweight VMs that feel and perform like containers, but provide the workload isolation and security advantages of adding a virtual machine layer. The Kata project is led by Architecture Committee members Eric Ernst (Intel) and Jon Olson (Google), Samuel Ortiz (Intel), Xu Wang (Hyper) and Wei Zhang (Huawei).

Since launching Kata in December 2017, the community has achieved several milestones including the 1.0 release in May followed by several point releases, joining the Open Container Initiative (OCI) and holding the first Architecture Committee elections.

Kata’s 1.0 release completed the merger of Intel’s Clear Containers and Hyper’s runV technologies and delivered an OCI compatible runtime with seamless integration for container ecosystem technologies like Docker and Kubernetes.

Most recently the project has made rapid advancements with the 1.4.0 release which offers better logging, ipvlan/macvlan support through TC mirroring, and NEMU hypervisor support. Since its launch, Kata Containers has scaled to include support for major architectures, including AMD64, ARM and IBM p-series. The 1.5 release is currently planned for mid January 2019, and will offer support for containerd v2 shim among other features. The team is also collaborating and exploring opportunities to support the new Firecracker micro VM alongside NEMU and QEMU.

A recap of Kata’s first year activities can be found in this Superuser post. View the Kata Containers talks from the 2018 KubeCon/CloudNativeCon events here and the 2018 OpenStack Summits here. Looking ahead to 2019 the Kata community plans to focus on growing and supporting it’s users, leading the way for open collaboration around container security efforts and better defining its value within the greater container landscape.

OSF Project Updates



  • The Airship team is currently working away at their 1.0 release due in early 2019. The work in progress for the Airship 1.0 release included improvements across the following areas: Airship will be adding support for Ironic as a bare-metal deployment platform. This work is currently in the proof-of-concept phase. If you’re interested in helping to design the bare-metal interface to the Ironic driver, please join the team for their weekly design meetings. Details for each meeting can be found in the airship-discuss mailing list.


  • The community is actively planning for the contributor meetup on January 15-16, 2019
  • The TSC finalized the initial project governance which is available on the governance page documentation website
