Docker is an open-source project that automates the deployment of applications inside software containers. These application containers are similar to lightweight virtual machines, as they can be run in isolation from each other and the running host.

Docker is an open-source containerization engine, which automates the packaging, shipping, and deployment of any software applications that are presented as lightweight, portable, and self-sufficient containers, that will run virtually anywhere. A Docker container is a software bucket comprising everything necessary to run the software independently. There can be multiple Docker containers in a single machine and containers are completely isolated from one another as well as from the host machines

Dockerfiles:

Dockerfiles are files used to programmatically build Docker images. They allow you to quickly and reproducibly create a Docker image, and so are useful for collaborating. Dockerfiles contain instructions for building a Docker image by using the docker build commands

Dockerfiles are of the form:

# This is a comment INSTRUCTION arguments

Instructions are upper case only
The first instruction of a Dockerfile must be FROM to specify the base image

Now you have learned some basics terminologies let’s start with the demonstration

Launch Graphical User Interface Inside Docker Container

Step 1: Create a directory

Create one directory where code will be saved here dockergui is a directory inside that we create a Dockerfile

Step 2: Write a code to create a Dockerfile

Step 3: Build the image

-t 👉 terminal
firefox_gui 👉Give any name

Step 5: Check the Build image

Step 5: Run the Command
docker run -it - -env= “DISPLAY” - -net=host - -name<give any name of your choice> <image name>
--net = for using host’s network
--env = for using environmet varibale (DISPLAY)
Step 6: Firefox will launch Successfully
