GUI Application on Docker

Running a GUI program in Docker can be a useful technique when you’re evaluating a new piece of software. You can install the software in a clean container, instead of having to pollute your host with new packages.

Here we will know how to run gui application like Firefox , Jupyter Notebook in our Docker container.

Steps:

• Install docker

Firstly, Install the Docker and start and check it. For this part refer to the following blog.

Configuring HTTPD Server and running Python code on Docker Container

• Now let’s install a GUI application like firefox inside the container.

yum install firefox -y

• After the installation let’s start firefox.

It is showing Error

It gives some error saying that no display environment variable specified. So we require some display environment to run GUI applications.

• Now launch one more container with env $DISPLAY, and install firefox.

docker run -it — net=host — env=”DISPLAY” centos

Here I am using — net = host, because I want to use network of host system. So everything for connecting and networking we will use our host system for it.

• Again run firefox.

Now it Works Perfectly.

• Now Let’s install jupyter notebook.
• For intalling Jupyter Notebook, first we have to install python3.

yum install python3 -y

• Then install Jupyter

pip3 install jupyter

• After installation is complete launch jupyter notebook

jupyter notebook — allow-root

Jupyter Notebook is Successfully launched on Docker Container!!
