Kata Containers with virtio-fs

Introduction

Container deployments utilize explicit or implicit file sharing between host filesystem and containers. From a trust perspective, avoiding a shared file-system between the trusted host and untrusted container is recommended. This is not always feasible. In Kata Containers, block-based volumes are preferred as they allow usage of either device pass through or virtio-blk for access within the virtual machine.

As of the 2.0 release of Kata Containers, virtio-fs is the default filesystem sharing mechanism.

virtio-fs support works out of the box for cloud-hypervisor and qemu, when Kata Containers is deployed using kata-deploy. Learn more about kata-deploy and how to use kata-deploy in Kubernetes here.
