Known Issues

No Filesystem retention on VM restart except for /mnt/sda1 affects saving PVC mounts

/dev/sda1       127380716    1441984 118582372   2% /mnt/sda1
$ ls /mnt/sda1
_16g  data  hostpath-provisioner  hostpath_pv  lost+found  var

/tmp is mounted into /dev/sda1 - so it is saved
$ findmnt | grep provisioner
| `-/tmp/hostpath-provisioner                                                                                                        /dev/sda1[/hostpath-provisioner] ext4             rw,relatime

Therefore if the default mountpath of /tmp/hostpath-provisioner is used as in https://github.com/kubernetes/minikube/blob/v0.30.0/pkg/storage/storage_provisioner.go#L49 we will loose the files after a minikube stop/start. It would be advisable to modify the storageclass post VM start without going through a 2nd mount to /dev/sda1 - see https://github.com/kubernetes/minikube/issues/3318

Proxy Minikube Docker in Host

There is a need to build a docker image or pre-pull docker images into the minikube vm. We can use the docker instance from the osx host by following https://github.com/kubernetes/minikube/blob/0c616a6b42b28a1aab8397f5a9061f8ebbd9f3d9/README.md#reusing-the-docker-daemon

before we get docker desktop
