Problem when I create a docker-machine on Debian 8

Archive Machine

Hi everyone,

I have a problem when I’m creating a docker-machine on my Debian 8 server.

When I’m running :

docker-machine -D create --driver virtualbox test

I have that error :

STDOUT: Waiting for VM "test" to power on...
VM "test" has been successfully started.

STDERR:
Starting VM...
Getting to WaitForSSH function...
Testing TCP connection to: localhost:60640
Using SSH client type: external

&{/usr/bin/ssh [/usr/bin/ssh -o PasswordAuthentication=no -o IdentitiesOnly=yes -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null -o LogLevel=quiet -o ConnectionAttempts=3 -o ConnectTimeout=10 -i /root/.docker/machine/machines/test/id_rsa -p 60640 docker@localhost exit 0] []  <nil> <nil> <nil> [] <nil> <nil> <nil> <nil> false [] [] [] [] <nil>}
SSH cmd err, output: exit status 255:
Error getting ssh command 'exit 0' : exit status 255
Getting to WaitForSSH function...
Testing TCP connection to: localhost:60640
Using SSH client type: external
About to run SSH command:
exit 0

When I’m trying to list my docker machine I have that :

$ docker-machine ls
error getting URL for host test: exit status 255
error getting URL for host test: exit status 255
error determining if host is active for host test: exit status 255
NAME   ACTIVE   DRIVER       STATE     URL   SWARM
test            virtualbox   Running

I’m running :

$ VBoxManage -v
5.0.6r103037

$ docker -v
Docker version 1.8.2, build 0a8c2e3

$ docker-machine -v
docker-machine version 0.4.1 (e2c88d6)

this is interesting , is there any other errors , it seem that it did build
the “test” docker host that you wanted it to

can you ssh into the “test” docker host?

No, I can’t :

$ docker-machine -D ssh test

Hi,

Are you sure you have SSH client installed in your machine?

Hi ranjandas,

an SSH client is installed on my machine :

$ ssh -V
OpenSSH_6.7p1 Debian-5, OpenSSL 1.0.1k 8 Jan 2015

Maybe this can help :

Okay Guys,
I found something…

the config.json have a wrong SSHPort and My SSH client tried to connect and return an error.

My solution :

vi /root/.docker/machine/machines/test/config.json

And add the SSH port for example :

ssh -o PasswordAuthentication=no -o IdentitiesOnly=yes -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null -o LogLevel=quiet -o ConnectionAttempts=3 -o ConnectTimeout=10 -i /root/.docker/machine/machines/test/id_rsa -p 60640 docker@localhost

I have to put in the config.json :

"SSHPort":60640

But I have the same error every time I create a docker-machine. I have to do the same thing. After that, I can connect to my machine with :

docker-machine ssh test
