Pengwin: WLinux Docker for Windows secure bridge has unexpected behaviour

Created on 21 Nov 2018  Â·  21Comments  Â·  Source: WhitewaterFoundry/Pengwin

Describe the bug
Docker support inside WLinux does not behave as expected.

To Reproduce
Steps to reproduce the behavior:

  1. WLinux distribution installed
  2. Install a secure bridge to Docker for Windows (WLinux support)
  3. Start Docker for Windows in background
  4. Open cmd.exe
  5. Run command docker ps -a, command works as expected
  6. Run command docker images, command works as expected
  7. Open wlinux (or if WLinux is default distro wsl also works)
  8. Run docker ps -a
  9. See error:
    sh error during connect: Get http://%2Fvar%2Frun%2Fdocker.sock/v1.38/containers/json?all=1: EOF
  10. Run docker images
  11. See error:
    sh error during connect: Get http://%2Fvar%2Frun%2Fdocker.sock/v1.38/images/json: EOF

Expected behavior
Docker commands should be supported considering the Docker support is installed inside WLinux with wlinux-setup

Basic Troubleshooting Checklist

[x] I have searched Google for the error message.
[x] I have checked official WSL troubleshooting documentation: https://docs.microsoft.com/en-us/windows/wsl/troubleshooting#confirm-wsl-is-enabled.
[x] I have searched the official Microsoft WSL issues page: https://github.com/Microsoft/WSL/issues.
[x] I have searched the WLinux issues page: https://github.com/WhitewaterFoundry/WLinux/issues.
[x] I have reset WLinux: Settings->Apps->Apps & features->WLinux->Advanced Options->Reset.
[x] I have disabled and re-enabled WSL in Windows Features.
[x] I have run Windows 10 updates and restarted.

I suspect the culprit is wslpath -- specifically, wHome=$(wslpath -u ${wHomeWinPath}) on line 739 of setup in function dockerinstall_build_relay.
It looks like this step is performed before the root is changed from /mnt to /, and so C: is mounted at /mnt/c at that time.

Hello,

Please run wlinux-setup again and be sure you select yes to the upgrade setup prompt. We just pushed a fix for it, and tell us.

Regards,
Carlos

I've update the upgrade script just now, the result are unexpected:

  1. Setup selection:
    [*] DOCKER Install a secure bridge to Docker for Windows
  2. Further install step:
    Please go to Docker for Windows -> Settings -> General and enable 'Expose daemon on tcp://localhost:2375 without TLS' or upgrade your Windows version and run this script again.
  3. We can already notice that step 1. and step 2. are mutually exclusive, there is no "secure bridge" anymore ?
  4. OS version is latest ?
    OS Version: 10.0.18282 N/A Build 18282
  5. Additionally after this steps:
    /usr/bin/wslsys: line 82: /mnt/c/Windows/System32/reg.exe: No such file or directory /etc/setup: line 858: [[: Build:: syntax error in expression (error token is ":")
  6. Worth mentioning in a previous setup step (while trying to install Docker support in WLinux)
    [automount] root=/ enabled = true
  7. One could see that the root folder changed from root=/mnt/ to root=/ but the script expects /mnt/c... ??

I will skip the Expose daemon on tcp://localhost:2375 without TLS even though that one works.

I observed this behaviour too (error during connect: Get http://%2Fvar%2Frun%2Fdocker.sock/v1.38/containers/json?all=1: EOF error), immediately after a WLinux setup where I selected the Docker option. It seems as though the symlink to npiperelay.exe is incorrectly created -- as @n3rd4i observes above, the root for DrvFs mounts is set to / (which I agreed to during the setup), but the symlink is: /usr/local/bin/npiperelay.exe -> /mnt/c/Users/<username>/go/bin/npiperelay.exe, correcting the /mnt/c to /c made docker work for me.

Ok, let's try to solve it. Probably you have Windows 1809. The version is good no problem with that and the bridge without opening the port should work. Stay tuned I will try to reproduce, them and submit a patch

crramirez picture crramirez on 21 Nov 2018

@n3rd4i please paste here the result of: echo $PATH
@imgrant I am improving the symlink creation

And what happens if you execute: reg.exe query
'HKLM\Software\Microsoft\Windows NT\CurrentVersion' /v BuildLabEx directly
in your WLinux terminal?

I am a little blind because I don't have this insider version that you have
also in your path your windows folder is all caps "WINDOWS" instead of
"Windows" probably this is part of the problem

I found the error is with the version 1.9 of wslu. I don't understand why they hardcoded the path. I will be working on get rid of wslsys of dockerinstaller

crramirez picture crramirez on 22 Nov 2018

And what happens if you execute: reg.exe query 'HKLM\Software\Microsoft\Windows NT\CurrentVersion' /v BuildLabEx directly in your WLinux terminal?

Nothing, there is no printout.

If I run similar command in cmd.exe and I get this:

> reg.exe query "HKLM\Software\Microsoft\Windows NT\CurrentVersion" /v BuildLabEx

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion

I installed docker support with freshly updated setup and now I have more positive results. The only thing that could be ironed out later is that somehow, sometimes when I run docker comands within WLinux says that docker server is not running. In rest it looks fine

Hello,

Did you try closing and reopening WLinux after the installation?
Also did you use the latests wlinux-setup?

I had the same issue yesterday. Now after restart and stuff the issue is even weirder.

I can only use the docker bridge with zsh if I have the bash opened - else it doesn't work.
Not quite sure if it's still related to this one.

Hello @Morgy93,

This is a completely different issue related to using zsh instead of bash.
Can you file a bug for this please?

Closed because issues are devolving.

Please run wlinux-setup to get the latest version of the script and try again.

If you are having issues with zsh please open a separate issue.

Thank you.

For users with spaces in their user directory (e.g.: C:\Users\Aaron Friel), the script does not work and the symptoms are exactly as reported above. I've submitted PR #233 to handle exactly this case.
