Machine: v0.6.0 Error creating machine: Error detecting OS: Too many retries waiting for SSH to be available.

[aharpervc]

Windows 10 x64 (version 1511, build 10586.63)

> docker-machine --version
docker-machine.exe version 0.6.0, build e27fb87

the machine appears to being creating ok, but then I see a series of retried ssh connections ending in failure:

> docker-machine -D create --driver=hyperv test

The machine exists but with a problem:

> docker-machine ls

And, I confirmed that C:\Users\user\.docker\machine\machines\test\server.pem does not exist. The folder does & there's other stuff in there as expected, but no pem.

Hm, I'm not really sure it's supposed to be going to IPv6 by default. Our SSH code might not handle that exactly properly.

Struggling with the same thing. Looks like the problem is here:

Judging from error message it is the space in un-escaped C:Program Files (x86)Gowbinssh.bat path. Is there a way to make it use a different SSH? Or somehow configure the SSH command to be used?

[dbarvitsky]

A bit of an update - got it working on Windows 10 x64 + Hyper-V. Bruteforce hack for now - install mingw64 into a folder that does not have spaces (e.g. C:Tools) and then re-run docker -D provision . The Gow did not work for me because it actually uses plink for SSH, and plink does not understand -o options.

For poor souls who have to run on Windows it would be very helpful to have some sort of config file where dependent tools for docker-machine are listed and configured.

[alixandru]

Indeed Gow is the culprit (more exactly the ssh alias it makes which points to plink). You could get it working by taking Gow out of your PATH (if you can live with that) or using Git Bash instead of cmd. See also #3152

Hopefully this will be solved in docker-machine itself. @nathanleclaire what do you think?

[nathanleclaire]

Hm, we probably should verify that it's actually OpenSSH we're detecting with os.LookPath("ssh"). You should be able to use --native-ssh to get around this in create for now. I do think a configuration file for Machine would be nice but is a bit large in scope.

Re @nathanleclaire suggestion on --native-ssh, that's an option for docker-machine itself, not for the create, this worked for me:

docker-machine --native-ssh create foo-vm --driver hyperv
[...]
docker-machine --native-ssh ssh foo-vm

where as this docker-machine create foo-vm --driver hyperv as mentioned before goes on timeout with Error creating machine: Error detecting OS: Too many retries waiting for SSH to be available. Last error: Maximum number of retries (60) exceeded, and this docker-machine ssh foo-vm gives exit status 255.
