 ===== Execute GUI programs =====
+You can create a Dockerfile where you install a Firefox, a Visual Studio Code... Whatever. Then, as the X11 Linux programs work like client\server you only need to bind the socket. \\
+For example, a Dockerfile could be this:
+<code>
+FROM ubuntu:14.04
+RUN apt-get update && apt-get install -y firefox
+RUN export uid=1000 gid=1000 && \
+    mkdir -p /home/developer && \
+    echo "developer:x:${uid}:${gid}:Developer,,,:/home/developer:/bin/bash" >> /etc/passwd && \
+    echo "developer:x:${uid}:" >> /etc/group && \
+    echo "developer ALL=(ALL) NOPASSWD: ALL" > /etc/sudoers.d/developer && \
+    chmod 0440 /etc/sudoers.d/developer && \
+    chown ${uid}:${gid} -R /home/developer
+USER developer
+ENV HOME /home/developer
+CMD /usr/bin/firefox
+</code>
+Then you only need to buid it:
+<code>
+docker build -t firefox .
+</code>
+And launch it using your x11 socket:
+<code>
+docker run -ti --rm \
+       -e DISPLAY=$DISPLAY \
+       -v /tmp/.X11-unix:/tmp/.X11-unix \
+       firefox
+</code>
+You could also use the run with the cmd as parameter, in this way you could install several programs and launch them with this.
+==== Launch them from SSH ====
+As it says here [[https://docs.docker.com/engine/examples/running_ssh_service/]] you can create a Dockerfile with...
+<code>
+FROM ubuntu:16.04
+RUN apt-get update && apt-get install -y openssh-server
+RUN mkdir /var/run/sshd
+RUN echo 'root:THEPASSWORDYOUCREATED' | chpasswd
+RUN sed -i 's/PermitRootLogin prohibit-password/PermitRootLogin yes/' /etc/ssh/sshd_config
+# SSH login fix. Otherwise user is kicked off after login
+RUN sed 's@session\s*required\s*pam_loginuid.so@session optional pam_loginuid.so@g' -i /etc/pam.d/sshd
+ENV NOTVISIBLE "in users profile"
+RUN echo "export VISIBLE=now" >> /etc/profile
+EXPOSE 22
+CMD ["/usr/sbin/sshd", "-D"]
+</code>
+... for an ssh server.
+This one will be prepared for launching a remote firefox in your local machine if you connect to it via ssh and launch it.
+<code>
+FROM ubuntu:14.04
+RUN apt-get update && apt-get install -y firefox openssh-server
+RUN mkdir /var/run/sshd
+RUN echo 'root:train' | chpasswd
+RUN sed -i 's/PermitRootLogin without-password/PermitRootLogin yes/' /etc/ssh/sshd_config
+# SSH login fix. Otherwise user is kicked off after login
+RUN sed 's@session\s*required\s*pam_loginuid.so@session optional pam_loginuid.so@g' -i /etc/pam.d/sshd
+ENV NOTVISIBLE "in users profile"
+RUN echo "export VISIBLE=now" >> /etc/profile
+RUN echo "X11UseLocalhost no" >> /etc/ssh/sshd_config
+EXPOSE 22
+CMD ["/usr/sbin/sshd", "-D"]
+# CMD tail -f /dev/null
+</code>
