Implement a minikube disk-usage command so users can see how much space minikube is using

[spowelljr]

There have been some comments by users that they find minikube uses a lot of disk space and there's no easy way to see how much it's using.

We should implement a command so users can easily view the disk space usage. This will include things like preloads and image caching and output the usage categorically.

• status: show guest VM health (cpu/ram/disk) #3574

But (also) needs to show the host disk usage, since it can vary greatly (GB) to what the VM is seeing...

Something similar to du -hs ~/.minikube/cache/*/ ~/.minikube/machines/*/, but probably done in Go ?

338M    /home/anders/.minikube/cache/images/
226M    /home/anders/.minikube/cache/iso/
205M    /home/anders/.minikube/cache/linux/
502M    /home/anders/.minikube/cache/preloaded-tarball/
4,4G    /home/anders/.minikube/machines/minikube/

In my case here, the biggest problem is the "rawdisk" of the libvirt driver. It causes the file to balloon.

Filesystem      Size  Used Avail Use% Mounted on
/dev/vda1        17G  1.7G   15G  11% /mnt/vda1

After compaction (qemu-img convert), the file is back to 1.7G again. Other drivers could have similar ?

This is also relative.

Minikube does consume a lot of disk space, compared to previous solutions like docker-machine and localkube.

174M /home/anders/docker-machine-minikube-install/localkube/

784M /home/anders/.docker/machine/machines/default/

But it should consume a comparable amount, when compared to something like vagrant and plain kubeadm ?

A couple of GiB is "expected".

• The minikube ISO is approximately half (250M), compared to the various ISO for cloud* (500M)

* https://cloud-images.ubuntu.com/focal/current/*.img

• The minikube binaries (uncompresssed) are something like double, compared to the deb packages.

• The minikube preload is approximately double (500M), compared to the images tarball* (250M)

* kubeadm config images list | xargs docker save | pigz

• The minikube preload also includes the size of the storage provisioner and kubernetetes dashboard.

I agree with the fucntionatliy be useful, how about adding a generic command called
that could later add more stuff in addition to disk usage.

"minikube info"
