Debian – Docker/Kubernetes (Minikube) boot time – mount: unknown filesystem type ‘glusterfs’

I'm trying to set up a kubernetes/docker container (using Minikube) with a glusterfs volume mounted, but every time I try to start the service/pods I get "mount: unknown filesystem type 'glusterfs'" in the error logs.

However when I start the container without the volumes setup in the kubernetes configuration, add an entry for the server to /etc/hosts, create a mount point and then mount it manually it works fine. Additionally the persistent volume is shown as claimed despite erroring out.
