octave-docker

What

octave docker setup to work in my mac os x machine in order to follow the machine learning coursera course

Prerequisistes

This was tested in macOS Sierra 10.12.4

Docker

Figure out how to install docker in your system.

Socat

brew install socat

XQuartz

brew cask install xquartz

Comands

Build docker image

In the same directory as the Dockerfile run:

docker build -t octave .

Open XQuartz

After the build run this command:

open -a XQuartz

This will open x11 application.

Go to the XQuartz preferences,then select the “Security” tab and enable the option “Allow connections from network clients”

Run Socat

Now, in another terminal window, run the following command:

socat TCP-LISTEN:6000,reuseaddr,fork UNIX-CLIENT:\"$DISPLAY\"

Enable connection

Run the following commands so you can figure out what is the ip that you can connect the docker image with the XQuartz display:

ip=$(ifconfig en0 | grep inet | awk '$1=="inet" {print $2}')

and then

xhost + $ip

this will output something like this:

192.168.25.6 being added to access control list

grab the ip address and use in the next command

Run the docker image

Finally, run:

docker run --rm -it -e DISPLAY=192.168.25.6:0 -v $(pwd):/source octave

run :

plot(eye(5))

and see if a window with the plot appears, if so then everything is probably working fine.

The commands are basically from here

And the Dockerfile is forked from here
