This repository contains the implementation of Kata remote hypervisor. The remote hypervisor concept is currently work in progress. The primary purpose of remote hypervisor support is to create Kata VMs alongside the Kubernetes worker node VMs, without requiring any nested virtualization support.
- Accept requests from Kata shim to create/delete Kata VM instances without requiring nested virtualization support.
- Manage VM instances in the cloud to run PODs using cloud (virtualization) provider APIs
- Forward communication between kata shim on a worker node VM and kata agent on a pod VM
- Provide a mechanism to establish a network tunnel between a worker and pod VMs to Kubernetes pod network
The high level architecture is described in the picture below
- Cloud API adaptor (cmd/cloud-api-adaptor) -
cloud-api-adator
implements the remote hypervisor support. - Agent protocol forwarder (cmd/agent-protocol-forwarder)
- A modified version of Kata containers to support remote hypervisor based on CCv0 branch (not included in this repository)
