Description

Is this a BUG REPORT or FEATURE REQUEST? Feature request/query

Minikube version (use minikube version): v0.30.0

  • OS: Arch Linux
  • VM Driver: None

The minikube docs list a number of locations that Minikube can provision persistent volumes, as well as sample config for a PV, but there doesn't seem to be any way to configure the storage-provisioner to provision volumes anywhere but /tmp/hostpath-provisioner. Unless I'm misunderstanding the source, it looks like the path in tmp is fixed and unparameterised. Is there some way of providing a patched storage-provisioner to minikube with a path of the user's choice? Our use case involves persisting a lot of large data files, for which a tmpfs-based PV quickly becomes impractical.

Research direction
The issue requests a configurable mount path for PVs in minikube. The current implementation in `pkg/storage/storage provisioner.go` hardcodes `/tmp/hostpath provisioner`. A new flag or environment variable should be added to allow users to set the default path. The relevant documentation is in `docs/persistent volumes.md`. Contributors should review the storage provisioner code and the minikube configuration handling to implement this feature.
