minikube hostpath mount permissions

[slashdottir]

Is this a BUG REPORT or FEATURE REQUEST? (choose one): BUG

Please provide the following details:

Environment:

minikube version: v0.33.1
OS macOS 10.13.6
VM driver: virtualbox
ISO Version: Boot2DockerURL: file://Users/foo/.minikube/cache/iso/minikube-v0.33.1.iso
Kubernetes: v1.10.11

What happened:
I'm trying to mount a local directory to be used by a container in kubernetes, but getting this error:

$ kubectl logs mysql-pd

chown: changing ownership of '/var/lib/mysql/': Input/output error

What you expected to happen:

I should be able to maintain a persistent volume for the mysql database that survives the container shutting down

How to reproduce it (as minimally and precisely as possible):

I'm starting up minikube with mounted directory:

minikube start --mount-string /Users/foo/mysql_data:/mysql_data --mount

deployment.yml

apiVersion: v1
kind: Pod
metadata:
  name: mysql-pd
spec:
  containers:
  - image: mysql:5.7
    name: mysql-container
    env:
    - name: MYSQL_ROOT_PASSWORD
      value: ""
    - name: MYSQL_ALLOW_EMPTY_PASSWORD
      value: "yes"
    ports:
      - containerPort: 3306
    volumeMounts:
    - mountPath: "/var/lib/mysql"
      name: host-mount
  volumes:
  - name: host-mount
    hostPath:
      path: "/mysql_data"

I suspect this may be a duplicate of #2290, but won't close this until I have more evidence that this is the case.

I believe this issue was resolved in the v1.1.0 release. Please try upgrading to the latest release of minikube, and if the same issue occurs, please re-open this bug. Thank you opening this bug report, and for your patience!

Same problem. When i try to mount a local directory to be used by a container in kubernetes, i get this error: Can't change data directory owner. But not after 90d of inactivity, but when i try to start it for the first time.
