How to Install Docker on Linux Mint
Linux Mint, known for its user-friendly interface and robust performance, is a popular choice among Linux enthusiasts. If you're looking to enhance your Linux Mint experience by incorporating Docker, a powerful platform for containerization, you're in the right place. In this guide, we'll walk you through the step-by-step process of installing Docker on Linux Mint, enabling you to leverage the benefits of containerized applications.
Before diving into the installation process, let's ensure your system meets the necessary prerequisites. Docker relies on a 64-bit version of Linux Mint and a compatible kernel. To check your system's architecture, open a terminal and enter the following command:
Ensure that the output is 'x86_64' for a 64-bit system.
- Update Package Lists:
It's good practice to ensure your system's package lists are up to date before installing any new software. Execute the following commands in the terminal:
sudo apt update
sudo apt upgrade
- Install Dependencies:
Docker requires some dependencies to be installed. Ensure these dependencies are present by executing the following command:
sudo apt install apt-transport-https ca-certificates curl software-properties-common
- Add Docker GPG Key:
Add Docker's GPG key to ensure the authenticity of the software packages during installation:
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg
- Set Up Docker Repository:
Next, add the Docker repository to your system's software sources:
echo "deb [signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
- Install Docker Engine:
With the repository added, update the package lists again and install the Docker Engine:
sudo apt update
sudo apt install docker-ce docker-ce-cli containerd.io
- Verify Docker Installation:
Confirm that Docker has been successfully installed by running a simple test:
sudo docker run hello-world
If everything is set up correctly, you'll see a welcome message indicating that your Docker installation is working.
- Manage Docker as a Non-root User (Optional):
To avoid using
sudoeach time you run a Docker command, add your user to the 'docker' group:
sudo usermod -aG docker $USER
Log out and log back in or restart your system for the changes to take effect.
