Omni Infrastructure Provider for KubeVirt

Can be used to automatically provision Talos nodes in a KubeVirt cluster.

Running Infrastructure Provider

First you need to create a service account for the infrastructure provider.

$ omnictl serviceaccount create --role=InfraProvider kubevirt

Set the following environment variables to use the service account:
OMNI_ENDPOINT=https://<account-name>.omni.siderolabs.io/
OMNI_SERVICE_ACCOUNT_KEY=<service-account-key>

Note: Store the service account key securely, it will not be displayed again

Create a service account kubeconfig for your KubeVirt cluster. Store it in kubeconfig file.

If you are using --data-volume-mode=Filesystem (which is the default), make sure to enable the ExpandDisks featuregate in KubeVirt, e.g.:

apiVersion: kubevirt.io/v1
kind: KubeVirt
spec:
  configuration:
    developerConfiguration:
      featureGates:
        - ExpandDisks

By default VMs will use the bridge network binding mode. In IPv6 environments you might want to use passt instead. Make sure to set the provider configuration in your MachineClass accordingly.

Using Docker

docker run -it -d -v ./kubeconfig:/kubeconfig ghcr.io/siderolabs/omni-infra-provider-kubevirt --kubeconfig /kubeconfig --kubeconfig kubeconfig --omni-api-endpoint https://<account-name>.omni.siderolabs.io/ --key <service-account-key>

Using Executable

Build the project (should have docker and buildx installed):

make omni-infra-provider-linux-amd64

Run the executable:

_out/omni-infra-provider-linux-amd64 --kubeconfig kubeconfig --omni-api-endpoint https://<account-name>.omni.siderolabs.io/ --key <service-account-key>
