# docker run -ti -rm -e DISPLAY=$DISPLAY -v /tmp/.X11-unix:/tmp/.X11-unix firefox Conclusion. Running GUI Apps in a Docker Container is really an awesome experience which will never harm/use your host Filesystem. It is fully dependent on your Docker Container. In this tutorial, we tried Firefox in our CentOS 7 Docker Image with Firefox installed. We can use many more GUI Apps with this technology. Already using Docker containers? How about run your GUI apps with it? That’s right, i’m talking about running your browser, text editor, games, etc. X11 running at Docker seems complicated. That’s quite easy (at least easier than most people think) and it gives you an astounding control over the application. BWC: GUI apps in Docker on OSX Running GUI apps inside Docker containers on your Mac, just because we can. This blog shows you how it works, what doesn’t work, and how to do it. February 12, 2016 docker. Perhaps slightly inspired by this blog by Jessica Frazelle I started putting some of the apps that I like to run on my Mac inside a. Docker run -dt redis. This creates a new Redis container. From the Docker menu, select Dashboard to see the new Redis container. Start a sample application. Let’s start a sample application. Download the Example voting app from the Docker samples page. The example voting app is a distributed application that runs across multiple Docker. Docker does not provide a display server that would allow to run applications with a graphical user interface. X11docker fills the gap. It runs an X display server on the host system and provides it to Docker containers. Additionally x11docker does some security setup to enhance container isolation and to avoid X security leaks.
Ok so here is the scenario:
You just got a nice new MacBook 15' Retina computer thinking it would work as nicely for Linux as your 13' MacBook did and then you discover that the hybrid Intel/Nvidia card support in Linux is a show stopper and the WebCam does not work under Linux.
Well that is what happened to me, so I decided to give working with OSX a try on this laptop with the help of docker for running all those essential apps that I use for development. One thing I was curious about was whether it would be possible to run native GUI (X11) applications from inside docker and have them show up on my OSX desktop. I turns out that it is fairly easy to do this - here is what I did:
Overview
- Install brew
- Install socat
- Install XQuartz
- Install Docker (I used Kitematic beta)
- Grab a docker image that has a gui app you want to run (I used my the QGIS Desktop image published by Kartoza on the docker hub)
- Run it forwarding the display to your OSX host
Digging In
Ok first install brew (an apt-like package manager for OSX).
Now install socat - a command line tool that lets you redirect sockets in unix like OS's - thankfully it runs in OSX too as it is a really neat tool!
Next we are going to install XQuartz - which basically gives you an X11 display client on your OSX desktop. Just grab the package at http://xquartz.macosforge.org/landing/ and do the usual OSX procedure for installing it.
Unfortunately docker does not run natively on OSX, and the whole boot2docker setup is probably quite difficult to explain to people. However there is a very nice (currently beta) docker client being developed for OSX called kinematic. I installed kinematic and then simply hit shift-command-t in order to get a bash shell with docker available in it.
Now grab my QGIS desktop image for docker:
How to view all the apps downloaded on mac. Once the image is downloaded we are done with the basic setup and can kick over to running our Linux GUI application (obviously QGIS in this example).
Running QGIS
Ok so there are four steps we need to do to run our Linux app:
- Start socat (in my testing it had to be done first)
- Start XQuartz
- Start Kinematic
- Start QGIS
I started socat like this:
It will run in the foreground waiting for connections and then pass them over to XQuartz.
Next I started XQuartz (you can close the XTerm window that opens by default). In X11 preferences in XQuartz, in the security tab, check both boxes:
Next I started kinematic, and pressed SHIFT-COMMAND-T to open a docker terminal.
Lastly I ran the QGIS docker container like this:

How to see all running apps on mac. How do I see a list of all running processes/tasks on macOS/OS X? Stack Exchange Network Stack Exchange network consists of 176 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. View the open processes on your Macbook in the 'Process Name' column. Click the 'All Processes' drop-down box near the top of the Activity Monitor window and select 'Windowed Processes' to view. Why to See All Running Apps and Processes on Mac. In case you are coming from a Windows computer, you must be used to opening the Task Manager on your Windows computer, in order to take a look at all the running apps and processes on your computer. In the case of a Mac, there are multiple ways to see all the Running Apps and Programs, ranging.
You can mix in any standard docker options there - in this case I created shared volume between my OSX home directory and a /home/timlinux directory in the container. You need to determine the IP address of your OSX machine and use it instead of the IP address listed after DISPLAY in the above command. Here is a nice picture of QGIS (from a Linux container) running on my OSX desktop:
This same technique should work nicely with any other GUI application under Linux - I will mostly use if for running tests of QGIS based plugins and for using QGIS in my docker orchestrated environments.
I recently run the OS X Server app on Yosemite. Now each time I shutdown or restart my mac, it asking for administrator password. I don't want to run my MacBook Pro as a server. I ran this app just to test something, now I want to reset to the previous state. Reinstall OS X Yosemite. The Mac maintenance and security app called Combo Cleaner is a one-stop tool to detect and remove OS X El Capitan virus. This technique has substantial benefits over manual cleanup, because the utility gets hourly virus definition updates and can accurately spot even the newest Mac. Uninstall apps mac os x yosemite.
This is a short guide explaining how to run GUI applications from within Docker on Mac. This uses XQuartz to enable to set the
DISPLAY
variable within the container.Install XQuartz
You can install XQuartz using homebrew with
brew cask install xquartz
or directly from the website here. At the time of writing, I had 2.7.11
installed on my machine with OSX El Capitan. After installing XQuartz restart your machine.Install Docker for Mac
Install docker using
brew cask install docker
or directly from the website here.Run XQuartz
Start XQuartz from command line using
open -a XQuartz
. In the XQuartz preferences, go to the “Security” tab and make sure you’ve got “Allow connections from network clients” ticked:Host Machine IP
IP=$(ifconfig en0 | grep inet | awk '$1'inet' {print $2}')
should set the IP
variable as the ip of your local machine. If you’re on wifi you may want to use en1
instead of en0
, check the value of the variable using echo $IP
.Now add the IP using Xhost with
xhost + $IP
. If the xhost command is not found check /usr/X11/bin/xhost
as that might not be in your path.Running a container
You can now try running firefox in your container with:

or run octave using:
