Installing Docker on Ubuntu

Introduction: Docker is a powerful tool for containerization. In this guide, we will walk you through the steps to install Docker on an Ubuntu system. Let's get started!

Prerequisites:

1. An Ubuntu instance.

Step 1: Update the Package Index

To begin, update the package index to ensure you have the latest package information:

sudo apt update

Step 2: Install Required Packages

Install necessary packages to allow APT to use repositories over HTTPS:

sudo apt install -y apt-transport-https ca-certificates curl software-properties-common

Step 3: Add the Docker Repository's GPG Key

Add the Docker repository's GPG key to your system:

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

Step 4: Add the Docker Repository to APT Sources

Add the Docker repository to APT sources:

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

Step 5: Update the Package Index Again

Update the package index once more to recognize the new Docker repository:

sudo apt update

Step 6: Install Docker

Finally, install Docker on your Ubuntu system:

sudo apt install -y docker-ce

Step 7: Start and Enable Docker

Start the Docker service and enable it to start on boot:

sudo systemctl start docker

sudo systemctl enable docker

Conclusion:

Congratulations! You have successfully installed Docker on your Ubuntu. You can now use Docker for your containerized applications and projects. If you encountered any issues during the installation process, please double-check the steps or consult the Docker documentation for troubleshooting.

That's it for this tutorial. Thank you for reading, and happy containerizing!
