How can you install and configure Docker on Linux?

Installing and configuring Docker on Linux is a straightforward process. Follow these steps to set up Docker on your Linux system:

1. Install Docker

1. Update your package manager: sudo apt update

2. Install necessary dependencies: sudo apt install apt-transport-https ca-certificates curl software-properties-common

3. Add Docker's official GPG key: curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

4. Add the Docker repository: sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"

5. Update the package database once again: sudo apt update

6. Install Docker: sudo apt install docker-ce

2. Configure Docker

1. Start and enable the Docker service: sudo systemctl start docker and sudo systemctl enable docker

2. Add your user to the Docker group to run Docker commands without using sudo: sudo usermod -aG docker $USER

3. Log out and back in or restart your system to apply the group changes

Now Docker is installed and configured on your Linux system. You can start using Docker to containerize your applications and services efficiently.
