RUN GUI Applications In Docker Container

 

RUN GUI Applications In Docker Container 


What is Docker?

  • Docker is a containerization platform tool for building an application in which container contains packaged binary files and its library files with its required dependencies, and further these containers are easily shipped to run on other machines.          
  • Each and every application runs on separate containers and has its own set of dependencies & libraries.

What is a Docker container?

  • Docker containers are basically runtime instances of Docker images.
  •  Docker is a tool designed to make it easier to create, deploy and run applications by using containers. 


Now, let’s see how to launch GUI application in Docker -

1.  Make & Go to Directory

            mkdir dockergui
            cd dockergui




2 . Create A Dockerfile & Write Commands .

        To create Dockerfile

        vim dockerfile


 What is Dockerfile?

A Dockerfile is a text document that contains all the commands a user could call on the command line to assemble an image.
Commands:
FROM 
Use  FROM to set the base image for subsequent instructions. In every valid Dockerfile, FROM is the first instruction.
RUN
The RUN command to execute any instructions in a new layer on top of the current image. With each RUN command, we add something on top of the image and use it in subsequent 
CMD
The CMD command to provide default values of an executing container. In a Dockerfile, if we include multiple CMD commands, then only the last instruction is used. 


3. Build the Docker image using Dockerfile.

    docker build -t firefoxgui .

4.Launch the GUI Container.

        docker run -it --name guifirefox --env="DISPLAY" --net=host firefoxgui:latest



    --env="DISPLAY"
    It is used to display the firefox on the docker

    --net=host
     It is used to set up the host adapter with the container

Launch Successful :)



Thank You

Revolutionizing Industries: Solving Challenges with Ansible

Introduction In today's fast-paced and ever-evolving business landscape, industries face a multitude of challenges. From managing complex IT infrastructures to ensuring cybersecurity, optimizing workflows, and ensuring compliance, the demands on organizations are immense. Fortunately, Ansible, an open-source automation tool, has emerged as a powerful solution to address these challenges across various industries. Streamlined IT Operations One of the most significant challenges across industries is the management of complex IT infrastructures. Ansible simplifies this task by allowing organizations to automate repetitive IT operations, reducing the risk of errors and enhancing efficiency.Example: A multinational corporation uses Ansible to automate server provisioning and configuration management. This not only reduces deployment times but also ensures that each server is configured consistently, minimizing vulnerabilities and downtime. Enhanced Cybersecurity With the rising threat ...

Creating a Python Script to Capture and Process Face Photos

Image
In this tutorial, we'll learn how to use Python and OpenCV to capture a photo, detect faces, crop the face, and save it as a grayscale image.  We'll break down the process into the following steps: Step 1: Set Up Environment: Install OpenCV using pip install opencv-python. Ensure you have a camera connected to your device. Step 2: Capture a Photo: Import the necessary OpenCV library. Open a connection to the camera using cv2.VideoCapture(0). Check if the camera opened successfully. Step 3: Detect Faces: Load the cascade classifier for face detection using cv2.CascadeClassifier. Convert the captured photo to grayscale using cv2.cvtColor. Use detectMultiScale to detect faces in the grayscale image. Step 4: Crop and Save Face: If faces are detected, select the first face and extract its coordinates. Crop the face region from the original grayscale image. Save the cropped face as a grayscale image using cv2.imwrite. Step 5: Display Cropped Face: Show the cropped face using cv2.imsh...
