Namespace Creation in KubeOne

When deploying a Kubernetes cluster with KubeOne, I can specify the default namespace. Can I also declare some sort of list of namespaces that should be created once the cluster is up and running?

Hello,

In general creating such objects (or workloads in general) are up to the end user (or cluster admin who just created the cluster).

But there built-in way to share this: kubeone addons.
