This is a qemu-vm inside a docker container, for use with my Kubernetes cluster at home.
The entrypoint script sets up the necessary tap interfaces and bridges for each network interface you specify (defaults to eth0). Additionally, you can use --passthrough-first-nic to attempt to have the VM configured with the pod network (this generates some configuration based on routes, assigned IP address and DNS configuration).
The helm charts provided assume you have persistent storage working within your cluster. The default StorageClass is cephfs. Currently the requested PV size is not functional.
