Simplified Docker Installation on Ubuntu Server

This is a simplified hands-on approach. I have a GitHub script that automates this, but since it's your first time installing Docker, it's best to do it manually. Follow these steps to quickly install Docker and deploy a container on your Ubuntu Server:

1. Update Package Index

sudo apt update

2. Install Prerequisites

sudo apt install -y curl

3. Run the Official Docker Installation Script

curl -fsSL https://get.docker.com | sudo sh
  • Explanation:
    • This command downloads and runs Docker's official installation script.
    • It automatically adds the repository, GPG key, and installs the latest Docker Engine.

4. Enable and Start Docker Service

sudo systemctl enable docker
sudo systemctl start docker

5. Verify Installation

sudo docker --version

6. Add Your User to the Docker Group (Optional)

To run Docker commands without sudo:

sudo usermod -aG docker $USER

Log out and log back in for the group changes to take effect.

Benefits of This Installation Method

  1. Easy and Quick: Just a few commands cover the entire installation process.
  2. Future-Proof: The script always installs the latest stable version of Docker.
  3. Reliable: Maintained by Docker, ensuring security and up-to-date installations.

With Docker now installed, you’re ready to begin using containers to simplify your application development and deployment! 🚀
