How to Install Docker on different platform?

To install Docker on Windows, Linux, or Mac, follow the instructions below:

Windows:

Pre-requisites:

• Before installing Docker on Windows, make sure you have Windows 10 Pro or Enterprise (64-bit) installed. Windows Home Edition does not support Docker.

• Docker Desktop for Windows includes both Docker Engine and Docker Compose. It also installs VirtualBox and creates a Linux VM to run Docker containers. During installation, you can choose whether to use the Windows Subsystem for Linux (WSL) instead of the Linux VM.

• If you have Hyper-V or another virtualization platform installed on your system, you may need to disable it before installing Docker. Docker requires exclusive access to virtualization features.

Installation:

• Download Docker Desktop for Windows from the official Docker website.

• Double-click the downloaded file to start the installation process.

• Follow the on-screen instructions to complete the installation.

• Once installed, launch Docker Desktop from the Start menu or desktop shortcut.

Post Installation:

• If you encounter issues with networking or accessing shared drives after installing Docker, make sure to adjust the Windows Firewall settings and configure Docker to use the correct network settings.

• Docker Desktop for Windows also includes a Docker CLI (command-line interface) and a Docker Compose CLI. These tools allow you to manage Docker containers and services from the command line.

Linux:

Pre-requisites:

• Visit the Docker installation page for your Linux distribution.

• Docker is available for various Linux distributions, including Ubuntu, Debian, CentOS, Fedora, and more. Make sure to follow the installation instructions specific to your distribution.

• Docker can be installed on Linux using either the package manager or a script provided by Docker. The package manager method is recommended for most users.

• Follow the instructions to add the Docker repository to your package manager.

Installation:

• Install Docker using your package manager, for example, on Ubuntu, run the command sudo apt-get install docker-ce docker-ce-cli containerd.io.

• Start the Docker daemon using the command sudo systemctl start docker.

Post Installation:

• After installing Docker, you can run a simple test to check that it's working. Open a terminal and type sudo docker run hello-world. This will download a small test image and run a container from it.

• After installing Docker on Linux, you may need to add your user to the docker group to allow it to run Docker commands without using sudo. You can do this using the command sudo usermod -aG docker <username>, where <username> is your Linux username.

• Docker on Linux can also be configured to use a specific storage driver, such as overlay2 or btrfs, depending on your system configuration and requirements.

Mac:

Pre-requisites:

• Docker Desktop for Mac requires macOS 10.13 or newer.

• Docker Desktop for Mac includes both Docker Engine and Docker Compose. It also includes a built-in Kubernetes cluster for testing.

Installation:

• Download Docker Desktop for Mac from the official Docker website.

• Double-click the downloaded file to start the installation process.

• Follow the on-screen instructions to complete the installation.

• Once installed, launch Docker Desktop from the Applications folder.

• During installation, Docker Desktop for Mac will prompt you to enable certain features, such as file sharing and access to the Docker daemon from within containers. Make sure to enable these features if you need them.

Post Installation:

• Docker Desktop for Mac integrates with macOS's native virtualization framework, called Hypervisor Framework, to run containers. It does not require a separate virtual machine like on Windows or Linux.

• Docker Desktop for Mac also includes a Kubernetes CLI, which allows you to manage Kubernetes clusters running locally on your Mac.

• To access Docker from the command line on Mac, you can use the built-in Docker CLI or configure the shell to use the Docker CLI provided by Docker Desktop.

• Docker for Mac also includes a Docker CLI (command-line interface) that allows you to manage Docker containers and services from the command line. To open the CLI, click the Docker icon in the macOS menu bar and select "Open Docker Terminal".

• Docker for Mac allows you to run both Linux and Windows containers, depending on your system configuration and requirements. However, Windows containers require a separate virtual machine to run, which can impact performance and resource utilization.

Note: Make sure that your system meets the minimum requirements for Docker installation, and that virtualization is enabled in your BIOS/UEFI settings (for Windows and Linux).
