Kata Containers is an open source project and community working to build a secure container runtime with lightweight virtual machines that feel and perform like containers, but provide stronger workload isolation by taking advantage of hardware virtualization technology as an additional layer of defense.
Collecting metrics in Kubernetes for Kata Containers sandboxes poses unique challenges: direct inspection of the container workloads is impossible from outside the virtual machine and the hypervisor and guest OS used in the sandboxes can only be monitored through the usage of custom metrics.
After a quick introduction to Kata Containers, we will describe how the collection of container metrics works in Kubernetes for traditional (runc) and Kata Containers runtimes. We will then show how to enable the collection of the extra Kata Containers custom metrics on a Kubernetes cluster, describing the architecture and the involved actors required to make this possible.
