Xauthority becomes an issue with newer systems. I can either discard any protection with xhost + before running my docker containers, or I can pass in a well prepared Xauthority file. Typical Xauthority files are hostname specific. With docker, each container can have a different host name (set with docker run -h), but even setting the hostname of the container identical to the host system did not help in my case.

While the IT world is embracing Containers Technology primarily for Enterprise Server Applications, There is also a huge scope of Docker Containers impacting the Desktop and Development Environment. This article introduce how to run GUI apps and Firefox with Docker for Mac, the purpose is just for fun, maybe can be used for build Website test automation with docker, you can check this. All the commands below are tested with Docker 17.03.0-ce, macOS 10.12.3 and XUbuntu 16.04.2.

Xeyes (I like this example) simply would ignore the magic cookie and pass no credentials to the server. Hence we get an error message 'No protocol specified Cannot open display' The Xauthority file can be written in a way so that the hostname does not matter. We need to set the Authentication Family to 'FamilyWild'. I am not sure, if xauth has a proper command line for this, so here is an example that combines xauth and sed to do that. We need to change the first 16 bits of the nlist output. The value of FamilyWild is 65535 or 0xffff.

Docker build -t xeyes. With docker data volumes it's very easy to expose xorg's unix domain socket inside the container. For example, with a Dockerfile like this: FROM debian RUN apt-get update RUN apt-get install -qqy x11-apps ENV DISPLAY:0 CMD xeyes You could do the following: $ docker build -t xeyes. Here's a lightweight solution that avoids having to install any X server, vnc server or sshd daemon on the container. What it gains in simplicity it loses in security and isolation. It assumes that you connect to the host machine using ssh with X11 forwarding. In the sshd configuration of the host, add the line X11UseLocalhost no So that the forwarded X server port on the host is opened on all interfaces (not just lo) and in particular on the Docker virtual interface, docker0.

Download jfsnip 1.1 for mac. The container, when run, needs access to the.Xauthority file so that it can connect to the server. In order to do that, we define a read-only volume pointing to the home directory on the host (maybe not a wise idea!) and also set the XAUTHORITY variable accordingly. Docker run -v $HOME:/hosthome:ro -e XAUTHORITY=/hosthome/.Xauthority That is not enough, we also have to pass the DISPLAY variable from the host, but substituting the hostname by the ip: -e DISPLAY=$(echo $DISPLAY sed 's/^.*:/$(hostname -i):/') We can define an alias: alias dockerX11run='docker run -v $HOME:/hosthome:ro -e XAUTHORITY=/hosthome/.Xauthority -e DISPLAY=$(echo $DISPLAY sed 's/^.*:/$(hostname -i):/')' And test it like this: dockerX11run centos xeyes. I only tried the Xfce4 and IceWM (which is in that repo). Of course the experience will be limited, for example mounting devices will not show up in the desktop (gvfs) unless you pass --device /dev/. To the docker and set necessary --cap privileges.

That defeats the purpose of containment, but you can pass through devices. With some tweaking it should be possible I believe to run GNOME/KDE under VNC. I ran multiple X in docker with nvidia cards (no VNC or Xpra), so that is certainly doable. – Jun 1 '17 at 19:39 •.

$ docker run hello-world Unable to find image 'hello-world:latest' locally latest: Pulling from library/hello-world ca4f61b1923c: Pull complete Digest: sha256:ca0eeb6fb05351dfc8759c20733c91def84cb8007aa89a5bf606bc8b315b9fc7 Status: Downloaded newer image for hello-world:latest Hello from Docker! Adobe photoshop cc free trial for mac. This message shows that your installation appears to be working correctly. • Start a Dockerized web server. Like the hello-world image above, if the image is not found locally, Docker pulls it from Docker Hub. $ docker run -d -p 80:80 --name webserver nginx • In a web browser, go to to view the nginx homepage.

Because we specified the default HTTP port, it isn’t necessary to append:80 at the end of the URL. Early beta releases used docker as the hostname to build the URL. Now, ports are exposed on the private IP addresses of the VM and forwarded to localhost with no other host name set. • View the details on the container while your web server is running (with docker container ls or docker ps): $ docker container ls CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 90 nginx 'nginx -g 'daemon off' About a minute ago Up About a minute 0.0.0.0:80->80/tcp, 443/tcp webserver • Stop and remove containers and images with the following commands. Use the “all” flag ( --all or -a) to view stopped containers. $ docker container ls $ docker container stop webserver $ docker container ls -a $ docker container rm webserver $ docker image ls $ docker image rm nginx Preferences menu Choose → Preferences from the menu bar and configure the runtime options described below. General General settings are: • Start Docker when you log in: Uncheck this option if you don’t want Docker to start when you open your session.
