linux-harbour

Docker image that allows running Linux apps on the Mac desktop

Prerequesites

XQuartz

Install XQuartz, an X11 server that will be used for display output:

brew install Caskroom/cask/xquartz

Need to change the security preferences:

• Open XQuartz, open the Preferences
• Go to the Security tab
• Ensure Authenticate Connections and Allow connections from network clients are both checked

Socat

Install socat, to tunnel from an open X11 port through to the local Unix socket where XQuartz is listening for connections

brew install socat

Docker Usage

Building the image

docker build -t harbour .

Running the Container

First, use socat to create a tunnel:

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

Spin up a container:

docker run -e DISPLAY=<IP ADDR>:0 --name harbour -d harbour

Where IP ADDR is the current IP address of your machine

Usage

Start XQuartz.

Build the harbour image:

sh build.sh

In a separate terminal tab, start the tunnel:

sh tunnel.sh

Spin up the container:

sh run.sh

This will open an XQuartz Chrome window.

Close the window to stop the container.

Use

sh run.sh <IP ADDR> rm

to automatically remove the image when it shutsdown.

To Do

• Implement automatic tunnel creation (+destruction)
