Docker-desktop and ubuntu 12.04

(Update 26/11/13) Docker 0.6.5 has a breaking change with ports and exposed.  It does not provide a port number when you run sudo docker port $CONTAINER_ID 22 anymore. You can assign the port you expose when you do the docker run command as shown below.

To get ubuntu 12.04 to connect to the xpra on the docker-desktop you need to do a few things to get a newer version of Xpra to install.

Ubuntu 12.04 has 0.0.7.36 which is a few years old now.

Ubuntu does not give you an updated version on its packages it knows about so you have to include a new apt-get repo to find it.

Explanation

Docker-desktop uses ubuntu 12.10 which has xpra version 0.3.11.  This is acting as the server.

On your ubuntu 12.04(client) has xpra version 0.0.7.36 will never connect properly to xpra(sever) 0.3.11 it will seem to connect but never log any information about what is going wrong and what is not working.

The 12.04(client) needs to update to xpra to version 0.9.8-1.  I have not gotten versions above 0.9.8-1 to work with xpra 0.3.11(server), tt has problems with rendering the screen.

OSX and docker-desktop via vagrant

(Update 26/11/13) Docker 0.6.5 has a breaking change with ports.   It does not provide a port number when you run sudo docker port $CONTAINER_ID 22 anymore. You can assign the port you expose when you do the docker run command as shown below.

Docker-desktop needs a few tweaks to get running on OSX.  I thought the instructions were inaccurate but the Roberto via quick emails figured out what I was doing wrong.

Install a version of Xquartz to allow viewing of X11 onto  your mac ??

http://xquartz.macosforge.org/landing/.
# version 2.75 works with mavericks.

Install version 0.9.0 of xpra.

This is a version that will work with version 0.3.11 of xpra.  0.3.11 is the version installed on ubuntu 12.10 when you create the docker-desktop.

Install 0.9.0 as your Xpra osx client.  You can use earlier versions but the versions 0.10.x and above have issues with colour pixels not working and you get a white screen.

Start of Docker install instructions:

  1. install vagrant if you do not have it already http://docs.docker.io/en/latest/installation/vagrant/
  2. Clone the docker project from git hub
    git clone https://github.com/dotcloud/docker.git

no /etc/resolve.conf ubuntu 12.04

Running the following and restarting fixed this.  Accepting changes to the conf.

You have to use the tab key to the the return key to work on any of the buttons.

 sudo dpkg-reconfigure resolvconf

History:

Ran into this there is no /etc/resove.confIn Ubuntu 12.04 and above this is a symlink to /run/resolvconf/resolv.conf

This is automatically generated by ubuntu.

When I did ls /run/resolveconf

postponed-update was the only file there.
