Machine: docker-machine can't remove machine

[jeanlaurent]

with the docker-machine 0.6.0 when you try to remove a machine in a weird state like this :

 Directory of C:\Users\docker\.docker\machine\machines\default
02/04/2016  03:11 PM        33,554,432 boot2docker.iso
02/04/2016  03:11 PM    <DIR>          default
02/04/2016  07:36 PM        88,195,072 disk.vhd
               2 File(s)    121,749,504 bytes

it fails :

C:\Users\docker>docker-machine rm -f default
About to remove default
Error removing host "default": open C:\Users\docker\.docker\machine\machines\default\config.json: The system cannot find the file specified.
Can't remove "default"

Just bumped into this on my Win 10 box as well. Are there any obvious workarounds or fixes?

Just managed to fix this! Follow the path that it's trying to access through Explorer: in my case, I had deleted those files manually in an attempt to remove the machine, because I couldn't remove it through docker-machine rm for some reason I can't remember , so I just created the missing folder and file:

1. Open Explorer
2. Go to C:\Users\your_user.docker\machine\machines
3. Create a folder named default
4. Open folder default
5. Create empty file config.json
6. Open Powershell
7. Run docker-machine rm -f default

PS E:\workspace\hubbles\sources> docker-machine rm -f default
About to remove default
WARNING: This action will delete both local reference and remote instance.
Error removing host "default": Error getting migrated host: unexpected end of JSON input
Successfully removed default
PS E:\workspace\hubbles\sources> docker-machine ls

Thanks for your reply! I was having this exact same issue.

I already tried what you said, but it wasn't working. But thanks to you I looked into it again.

For others having this issue, but still can't delete the machine when they add the config.json file:
Check if VBoxHeadless.exe is running (using task manager), this is probably using a file in the machine folder.
Kill it, make sure you have the config.json file and remove ->
Successfully removed default

Same issue on Windows 10 pro. I have not been able to fix this with either solution. VBoxHeadless.exe was not running.

Thanks @rdhaese , it worked for me!

I am using docker toolbox in a Windows 7 machine, uninstalling and installing the docker toolbox again fixed this issue for me. :)

Deleting C:\Users\\.docker folder worked for me

restart worked for me virtualbox 6.1
