In this article, we will guide you through the process of installing Docker on Kali Linux, a popular operating system used for penetration testing and ethical hacking.

Docker is a popular containerization platform used for deploying and running applications in a portable and efficient manner.

Docker is a powerful tool for containerization, enabling developers to deploy applications in a portable and efficient manner.

Kali Linux is a popular operating system used for penetration testing and ethical hacking.

By installing Docker on Kali Linux, you can take advantage of the benefits of containerization to streamline your development process and enhance your security testing capabilities.

Step 1: Update and Upgrade Kali Linux

Before installing Docker on Kali Linux, it is important to update and upgrade your system to ensure that you have the latest packages and security patches installed.

Open a terminal window and enter the following commands:

rfs@kali:~$ sudo apt update

Step 2: Install Docker

Once your system is up-to-date, you can install Docker using the following command:

rfs@kali:~$ sudo apt install -y docker.io

This will download and install the Docker package, along with any dependencies.

Step 3: Verify Docker Installation

To verify that Docker is installed and running correctly, you can use the following command:

rfs@kali:~$ sudo systemctl status docker

rfs@kali:~$ sudo systemctl enable docker --now

This will display the status of the Docker service and indicate whether it is running.

Step 4: Add User to Docker Group

By default, Docker can only be run by the root user. To allow other users to run Docker commands, you can add them to the Docker group using the following command:

rfs@kali:~$ sudo usermod -aG docker $USER
printf '%s\n' "deb https://download.docker.com/linux/debian bullseye stable" |
  sudo tee /etc/apt/sources.list.d/docker-ce.list
rfs@kali:~$  curl -fsSL https://download.docker.com/linux/debian/gpg |
  sudo gpg --dearmor -o /etc/apt/trusted.gpg.d/docker-ce-archive-keyring.gpg
rfs@kali:~$ sudo apt update
rfs@kali:~$ sudo apt install -y docker-ce docker-ce-cli containerd.io

By following these steps, you can easily install Docker on Kali Linux and take advantage of the benefits of containerization for your development and security testing needs.

Docker provides a lightweight and efficient way to deploy and run applications, making it an essential tool for developers and security professionals alike.
