GUI container on the Docker

Here i am running gui software firefox on docker container centos and launching a jupyter notebook on firefox .

I created a directory called sample and created a Dockerfile inside it using the command

#vim Dockerfile

when #vim Dockerfile run a new window is opened.

Press i to insert the data

FROM centos:

RUN yum install firefox -y

CMD ["usr/bin/firefox"]

to save it press esc+:wq+enter

To build an image run # docker build -t firefox .

To verify whether firefox is installed or not run #docker images.

Even though firefox is installed it will not launch successfully because docker container does not have a gui screen to run the firefox. So we need a environmental variable DISPLAY to use the host system's gui screen.run

#docker run -it --env="DISPLAY" --net =host firefox

Here we used --net=host ,when container is launched it provide us the firefox software in gui window, whatever we search in this window needs to go to the docker container via host .

firefox window is popped out on the screen.

GUI firefox is launched successfully.

Run # jupyter notebook --allow-root to launch the jupyter notebook on firefox.

Automatically it(jupyter notebook --allow-root) redirects to a firefox browser .

jupyter notebook is launched on firefox browser.
