[AlexandrePieroux]

Steps to reproduce the issue:

1. install minikube on macOS Big Sur 11.2.3 (minikube: stable 1.20.0 (bottled), HEAD) using: brew install minikube
2. create a new cluster using this command: minikube start --cpus 6 --memory 12288 --disk-size=50GB --vm=true
3. try to mount a folder using: minikube mount --uid 1000 --gid 1000 ./:/efs --v=10

I'm struggling with this on a fresh install of Minikube on OS X. It seems that the userspace file server fail to bind to the ip. I tried to set different IP but with no success.

I managed to make it work by specifying the ip manually. I don't know why Minikube was failing to determine the ip range in my case. The range my cluster was operating in was 192.168.65.0/8 but the mount operation was trying to bind to 192.168.64.0/8 (as it can be seen in the logs I posted).

By specifying '--ip 192.168.65.1' at the end of the command, it successfully bind and mount the volume.

[oleg-andreyev]

For reference

#!/bin/bash

set -x

minikube --v=9 --logtostderr mount $(pwd):/mnt/foo --ip=$(ifconfig en0 | grep "inet\b" | awk '{ print $2 }')

$(ifconfig en0 | grep "inet\b" | awk '{ print $2 }'

will return current IP of MacOS
