I have been trying to follow the instructions on https://learning-continuous-deployment.github.io/docker/images/dockerfile/2015/04/22/docker-gui-osx/ about running GUI apps in a docker container inside a MacBookPro host (using Docker tools).
I created a simple docker container using Fedora 23 and with firefox installed.
I try to run firefox and after about a minute I get the following error:
Unable to init server: Broadway display type not supported: 192.168.57.3:0
Error: cannot open display: 192.168.57.3:0
Does anyone have a clue what the error means and/or how to fix it?
This allows your container to use the X Server you already have. GUI applications running in the container would then appear on your existing desktop. Why Run GUI Apps in Docker? Running a GUI program in Docker can be a useful technique when you’re evaluating a new piece of software.
But did you know that you can just as well run applications with a graphical user interfaces, like Chrome, Firefox, Tor Browser, Gimp, etc… with Docker… on OS X! This article serves as transcript to our hands-on demo and as a quick refresher on how to run these kind of applications on a Mac in 5 minutes or less.
Also if you has the pre-configured Docker Image then you can launch your entire OS with the running server in it in just few seconds. Container is like an isolated environment to run your application.
The “ commit” command is used to create an image from your running container. To run a new docker container from your created os image in which you already install some GUI applications and env displays the environment that it received from its parent (base os), and set image name and version as you mentioned in the previous command.
On a Mac you may find the following steps useful:
open -a XQuartz
)xhost + $IP
(see note 1)Note 1: Here's a neat trick toget your ip address:
export IP=$(ifconfig en0 | grep inet | awk '$1=="inet" {print $2}')
Note 2: And an example docker run command to start firefox
docker run -it -e DISPLAY=$IP:0 -v /tmp/.X11-unix:/tmp/.X11-unix <image> firefox
