How to Install Docker on Different Operating Systems

Are you wondering how to get started with Docker? Do you want to learn how to install Docker on your computer? Look no further! In this article, we will guide you through the process of installing Docker on different operating systems, including Windows, macOS, and Linux.

What is Docker?

Docker is a platform that enables developers to build, ship, and run distributed applications, whether they are cloud-native or traditional. With Docker, you can containerize your applications and dependencies, making them independent of environments, operating systems, and infrastructures.

Installing Docker on Windows

Windows users can download Docker Desktop, a tool that simplifies the installation and management of Docker on Windows 10 Pro, Enterprise, and Education. Docker Desktop comes with a graphical user interface and a command-line interface, and it integrates with the Windows Subsystem for Linux (WSL) and Hyper-V.

To install Docker Desktop on Windows, follow these steps:

1. Download Docker Desktop for Windows from the Docker Hub.
2. Double-click the installer, and follow the prompts to install Docker Desktop.
3. After the installation, Docker Desktop will start automatically. You can verify that Docker is running by opening a PowerShell terminal, and running the command docker version.

Congratulations, you have installed Docker on Windows! You can now start creating and running containerized applications on your Windows machine.

Installing Docker on macOS

macOS users can also install Docker Desktop, which provides a seamless experience for running containers on macOS. Docker Desktop for Mac requires macOS El Capitan 10.11 or newer.

To install Docker Desktop on macOS, follow these steps:

1. Download Docker Desktop for Mac from the Docker Hub.
2. Double-click the downloaded .dmg file to open the Docker Desktop installer.
3. Drag the Docker icon to the Applications folder to install Docker Desktop.
4. After the installation, Docker Desktop will start automatically. You can verify that Docker is running by opening a terminal, and running the command docker version.

Great job, you have installed Docker on macOS! You can now start building and deploying containerized applications on your Mac machine.

Installing Docker on Linux

Linux users have several options for installing Docker, depending on their Linux distribution and preferences. In this section, we will cover the most common methods of installing Docker on Linux.

Installing Docker on Ubuntu

Ubuntu users can install Docker from the official Ubuntu repositories. Ubuntu 18.04 LTS and higher include the latest version of Docker, while older versions require additional steps to install Docker.

To install Docker on Ubuntu, follow these steps:

1. Open a terminal on your Ubuntu machine.
2. Update the package index and install the necessary dependencies for Docker:

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

3. Add the Docker GPG key and add the Docker repository to your system:

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

4. Update the package index again and install Docker:

sudo apt-get update
sudo apt-get install docker-ce docker-ce-cli containerd.io

5. After the installation, Docker should be running. You can verify that Docker is running by running the command sudo docker version.

Well done, you have installed Docker on Ubuntu! You can now start experimenting with containerization on your Ubuntu machine.

Installing Docker on CentOS

CentOS users can also install Docker from the official Docker repository. CentOS 7 and higher are supported by Docker, while CentOS 6 requires additional steps to install Docker.

To install Docker on CentOS, follow these steps:

1. Open a terminal on your CentOS machine.
2. Install the necessary dependencies for Docker:

sudo yum install -y yum-utils device-mapper-persistent-data lvm2

3. Add the Docker repository to your system:

sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

4. Install Docker:

sudo yum install docker-ce docker-ce-cli containerd.io

5. After the installation, Docker should be running. You can verify that Docker is running by running the command sudo docker version.

Awesome, you have installed Docker on CentOS! You can now start building and deploying containerized applications on your CentOS machine.

Conclusion

In this article, we have shown you how to install Docker on different operating systems, including Windows, macOS, Ubuntu, and CentOS.
