issue with ssh docker-desktop #7

Closed riverhuang1107 closed 11 years ago

riverhuang1107 commented 11 years ago

my test enviroment is: the win7 notebook. I installed virtual box on win7. And I installed ubuntu 12.04 on virutal box(I also installed xpra in the ubuntu).

when I execute the following command:

river@ubuntu:~$ sudo ssh docker@192.168.59.101 -p 49153 ./docker-desktop -s 800x600 -d 10

shows the following error:

hi @riverhuang82,

Could you please check your docker version by typing docker version ?

Also, I have updated the documentation according to the new run command behavior since docker version 0.6.6

You should run like this: CONTAINER_ID=$(docker run -d -P [username]/docker-desktop) Now we need to use the flag -P

riverhuang1107 commented 11 years ago

I haved updated the docker. Now the version is 0.7. And I run the docker run plus -P. But the error is the same. Is it possible that the issue is about the ubuntu running in virutalbox not in bare metal？

rogaha commented 11 years ago

No. It seems to be a problem with the xpra session inside of the container. Let's check step by step:

1) Show me output of this command: sudo ssh docker@192.168.59.101 -p 49153 ./docker-desktop -s 800x600 -d 10 It should ask your password and after you type it some messages should show up.

It's strange. Try to ssh the container only with ssh docker@192.168.59.101 -p 49153

rogaha commented 11 years ago

Show me the output of the ls command inside of the container.

Thanks

riverhuang1107 commented 11 years ago

ssh docker@192.168.59.101 -p 49153 runs O.K. I could login in the container. And in the container, I run ./docker-desktop, it shows the same output.

I think you have changed the dockerfile. For some reason fluxbox is not installed.

riverhuang1107 commented 11 years ago

The dockerfile I used was the old version... Now when I run river@ubuntu:~$ ssh docker@192.168.59.101 -p 49153 ./docker-desktop -s 800*600 -d 10, I entered the password, and just wait, no output code.

rogaha commented 11 years ago

Alright. Try with 800x600 instead of 800*600 and let me know how it goes

riverhuang1107 commented 11 years ago

Awesome! Now you can open the virtual desktop with xpra --ssh="ssh -p 49154" attach ssh:docker@192.168.59.101:10 from your host machine.

I ran xpra command in DOS, and the virtual desktop was not be opened yet. v 66pm 2 tvz t9v g7b3lw

Alright. I tested here and the problem is that the latest version of the Windows Xpra has some issues and it doesn't work. In order to make it works follow this steps:

1) Run on linux ssh docker@192.168.59.101 -p 49154 ./docker-desktop -s 800x600 -d 10 2) Install this version on windows https://www.xpra.org/dists/windows/Xpra_Setup_0.9.7-r3885.exe 3) Run on windws Xpra_cmd.exe --ssh="plink -P 49154" attach ssh:docker@192.168.59.101:10

It's capital P plink -P

Let me know how it goes!

I've updated the README file to reflect that version requirement! :)

Awesome!

From linux i would be possible only with you have a real Linux VM with a GUI. I saw that you were trying to do it from a terminal, but it's not possible because you don't have a GUI on Linux to support the virtual desktop.

You can download one Linux Distro, install it with VirtualBox in your Windows and it should work! :)
