Best Way to Install Docker on Kali Linux

INTRODUCTION

Are you finding it difficult to install Docker on your Linux machine?
Docker is a powerful platform that enables developers to build, ship, and run applications in containers. Installing Docker on Kali can be tasking. Running docker Linux is a straightforward process, and in this guide, we'll walk you through each step, explaining the command line scripts along the way. Let's get started.

PREREQUISITES

Before installing docker. it is important to get have the following prerequisites:

1. A kali Linux Machine (ensure it is up-to-date)
2. Access to the terminal with sudo privileges
3. Basic understanding of command line.

sudo apt update

output:

Step 2: Install Docker

Once the package lists are successfully installed, install Docker using the following command:

sudo apt install docker.io

output:

Step 3: Enable and Start Docker Services

Docker requires a service to be running in the background. This steps enables and start the docker service with the following commands:

sudo systemctl enable docker --now

output:

This command not only enables Docker to start on boot but also starts the service immediately.

Step 4: Check Docker Service Status

sudo reboot

Step 7: Verify Docker Installation

Confirm that Docker is successfully installed by checking its version:

docker --version

output:

This command displays the installed Docker version, confirming that the installation was successful.

CONCLUSION

Congratulations on successfully navigating through the installation of Docker on your Kali Linux machine! Docker brings a new level of flexibility and efficiency to your development and deployment workflows. With containers, you can ensure consistency across different environments, making your life as a developer much smoother. Feel free to explore Docker's vast capabilities and revolutionize the way you package and deploy applications.
Happy coding!
