Machine: Unable to run docker-machine due to SSH error

Created on 4 Jan 2016  路  34Comments  路  Source: docker/machine

Running any cmd against docker machine is failing due to an issue finding SSH keys on the machine (or so the error msg says). Regenerate certs does not fix the problem. Please see the logs attached below.

OS: OS X Yosemite
VBox: VirtualBox 5.0.6 r103037
Docker Machine: 0.5.2

Basic msg

> docker-machine env default

Error checking TLS connection: Error getting driver URL: Something went wrong running an SSH command!
command : ip addr show dev eth1
err     : exit status 255
output  : Warning: Identity file machines/default/id_rsa not accessible: No such file or directory.

I had the same issue with my Docker-Toolbox on Windows 7. I'm using docker in combination with VirtualBox.

Docker version

Client:
 Version:       18.03.0-ce
 API version:   1.35 (downgraded from 1.37)
 Go version:    go1.9.4
 Git commit:    0520e24302
 Built: Fri Mar 23 08:31:36 2018

 Experimental:  false
 Orchestrator:  swarm

 Engine:
  Version:      17.12.1-ce
  API version:  1.35 (minimum version 1.12)
  Go version:   go1.9.4

  Built:        Tue Feb 27 22:20:43 2018
  OS/Arch:      linux/amd64
  Experimental: false

Error cause

It was a missing port forwarding rule in VirtualBox which I removed accidentally

Fix

This steps fixed this issue for me:

  1. In VirtualBox manager go to your docker machine "default"
  2. Go to network settings / network adapter / advanced / port forwarding
  3. Add new port forwarding rule for SSH connection
  4. (host_port:guest_port) -> 49591 : 22
  5. You will get the right host_port if you run this command docker-machine ssh default -v

Your config file seems like it's gone sideways. My recommendation would be to upgrade to Machine 0.5.5, destroy and re-create the machine. If that doesn't work please re-open. Thanks!

nathanleclaire picture nathanleclaire on 4 Jan 2016

i have same issues, is there any solution that i don't have to delete the machine because i use it in production.

particle4dev picture particle4dev on 28 Jan 2016

@particle4dev What's the (sanitized output -- make sure not no API keys are present) of docker-machine inspect mcn?

nathanleclaire picture nathanleclaire on 29 Jan 2016

OK, there seems to be something that went sideways in a migration. That bit above where it says "StorePath": "" in the Driver object, if you edit the config.json and change it to "StorePath": "/home/dir/.docker/machine" (naturally, change /home/dir to your actual home directory), does it start working?

nathanleclaire picture nathanleclaire on 30 Jan 2016

Works like a charm. Thank you so much :). It seems like when i open kitematic app, it overwrite config files.

particle4dev picture particle4dev on 30 Jan 2016

You're welcome @particle4dev ! KM shouldn't re-write config files (especially for non-default machines) but it could potentially be a bug.

Hi @nathanleclaire , I am having a similar issue. Should I destroy and re-create the machine?

If you can, that is the simplest solution.

It worked!! awesome thanks @nathanleclaire

this happened to me twice today with docker-machine version 0.6.0, build e27fb87.
i didn't investigate the 1st incidence (just created a new machine), but 2nd time was too much.
something had overwritten the config.json without

        "SSHKeyPath": "/Users/me/.docker/machine/machines/mymac/id_rsa",
        "StorePath": "/Users/me/.docker/machine",

i added those back to the config and everything seems to be running fine again.

so, to me this sounds like a bug.

t0v picture t0v on 5 Feb 2016

same here. pretty annoying.
docker-machine version 0.6.0, build e27fb87

gregory picture gregory on 9 Feb 2016

The problem persists, even after updating Docker Machine. I'm thinking maybe we should reopen this one.

ElChupacabra26 picture ElChupacabra26 on 9 Feb 2016

I had the problem too today. As it turned out that I had two different docker-machine versions in place (one was called by a bash script which had an old docker-machine version in the path) and the old one always was overwriting the confif file whenever docker-machine ip [NAME] was used.

matlockx picture matlockx on 9 Feb 2016

@nathanleclaire - Sounds like this is definitely a bug, any plan to reopen this issue?

gregory picture gregory on 9 Feb 2016

@gregory Can you provide an end-to-end dupe? Does the issue happen with newly created machines as well?

nathanleclaire picture nathanleclaire on 9 Feb 2016

It's pretty easy to reproduce:

  • Using docker machine 0.6.0: docker-machine create -d virtualbox test
  • Using docker machine 0.4.2: docker-machine ls
  • Using docker machine 0.6.0: docker-machine ls
  • Output:

Thanks @recht -- Unfortunately 0.4.2 isn't forwards compatible and running docker-machine 0.4.2 commands after creating with 0.6.0 is destructive to the configuration file format. The recommendation is to always use the latest version of Docker Machine.

https://github.com/docker/machine/blob/master/libmachine/host/migrate.go#L65 was introduced to prevent using older Machine versions it but 0.4.2 did not contain this fix.

This happened to me right after changing the configuration of my VM's networking from NAT to Bridged. I don't see a SSHKeyPath variable (mentioned above by @t0v).

The weird thing is, I can still docker-machine start default and it'll bring it up, however, it won't connect. And I've had to hard-code the environment settings.

Should I change the networking back to NAT?

$ docker-machine --version

@GabLeRoux If possible, I'd highly suggest removing the machine and starting over from scratch (make sure to use the latest version of Docker Machine). docker-machine rm -f default && docker-machine create -d virtualbox default

Deleting this vm isn't a solution for me as I've worked on a wordpress container and I still need to figure out how to handle data inside this vm, I don't want to lose this data. At least, I got it working even tough it's complaining with the error I mentioned above. I used Kitematic app and I think kitematic updated the config and broke things.

I am now able to see wordpress but It seems to redirect me to 192.168.99.101 so maybe the machine ip changed for some reason once. I'll try to change my machine ip and see what happens. At least, I'm able to access data now so it should be alright :)

Edit: happened again using Kitematic :(
Looks like kitematic likes to break
~/.docker/machine/machines/default/config.json
It changed to a one liner json after running kitematic. I reverted to the working one, still complaining, but it works.

Getting these same errors when trying to run docker-machine --debug create --driver virtualbox default:

  • Error getting ssh command 'exit 0' : Something went wrong running an SSH command!
  • ERROR getting IP: No IP address found 4: eth1: mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
  • Error creating machine: Error checking the host: Error checking and/or regenerating the certs: There was an error validating certificates for host "192.168.99.100:2376": dial tcp 192.168.99.100:2376: i/o timeout

More Error Details: https://gist.github.com/richnsoos/8046721ec4f68951d20e

Before running the command, I:

  • added my ssh.exe folder to environment PATH variable
  • removed all VMs from VirtualBox
  • removed all Host Only Networks from the Network settings for VIrtualBox
  • removed all docker machines with docker-machine rm default

To those who might be able to help, here's my setup:

  • windows 7
  • VM VirtualBox 5.0.14
  • docker-machine version 0.6.0, build e27fb87
  • ~\.docker\machine\machines\default\config.json file does include these entries:

"SSHKeyPath": "C:\\Users\\sth787\\.docker\\machine\\machines\\default\\id_rsa", "StorePath": "C:\\Users\\sth787\\.docker\\machine",

These error are repeatable. If I delete the docker-machine and start fresh with same steps, I get the same errors. Thank you in advance!

3/7/16 Update: after re-running the same steps at work, docker was successfully up and running. I guess running these steps at home, through the VPN is what was causing problems. Thank you

This is still an issue with v0.6.0 - even if I try running docker-machine rm -f default && docker-machine create -d virtualbox default ssh tries to connect to 127.0.0.1 and exits with 255.

@jurjevic Did you try 0.7.0?

nathanleclaire picture nathanleclaire on 18 Apr 2016

I got the similar issue.

It is funny that the reason was just a file named ssh.bat in the current directory.
I removed it and everything works now for me!

then I modified config.json : add SSHKeyPath ,SSHPort, It works now.

I had the same issue with my Docker-Toolbox on Windows 7. I'm using docker in combination with VirtualBox.

Error cause

It was a missing port forwarding rule in VirtualBox which I removed accidentally

Fix

This steps fixed this issue for me:

  1. In VirtualBox manager go to your docker machine "default"
  2. Go to network settings / network adapter / advanced / port forwarding
  3. Add new port forwarding rule for SSH connection
  4. (host_port:guest_port) -> 49591 : 22
  5. You will get the right host_port if you run this command docker-machine ssh default -v

This solved it for me but the -v command showed port 22 so I mapped 22 to 22 in the port forwarding settings.

OK, there seems to be something that went sideways in a migration. That bit above where it says "StorePath": "" in the Driver object, if you edit the config.json and change it to "StorePath": "/home/dir/.docker/machine" (naturally, change /home/dir to your actual home directory), does it start working?

can you please say how to do it
