Welcome to our comprehensive guide on installing Docker in a different partition on Windows! In this post, we'll show you how to overcome the default installation limitations and effectively redirect Docker directories to another drive. By following these steps, you can optimize your system's storage and performance.

📋 Standard Installation
For a standard installation, follow the steps provided in the official Docker documentation, available here. This guide offers detailed instructions for various platforms, including Windows, macOS, and Linux.
🛠 Installation in a Different Directory (Windows)
🚧 Challenge Faced
In a Windows environment, as of the date of this document, the default Docker configuration does not allow direct selection of the installation directory during the installation process. This necessitated exploring alternatives to bypass this limitation.
Several approaches were investigated to resolve this issue. One involved creating symbolic links using commands like:
mklink /D "C:\ProgramData\Docker" "D:\Docker\ProgramData"
mklink /D "C:\ProgramData\DockerDesktop" "D:\Docker\ProgramDockerDesktop"
mklink /D "C:\Users\User\AppData\Local\Docker" "D:\Docker\AppData"
💡 Solution Found
However, none of these strategies proved effective in redirecting the directories as desired.
The approach that proved efficient was running Docker Desktop through the command prompt (cmd) and adding specific flags during the installation process, as shown in the example below:
start /w "" "Docker Desktop Installer.exe" install --installation-dir=D:\Docker\installation --wsl-default-data-root="D:\Docker\Dados\WSL"
Using this method, it was possible to redirect not only the main installation directory but also other directories associated with Docker to the desired paths.
📌 Note
It is important to note that the steps may vary depending on the versions of Docker or the operating system. Therefore, consult the official documentation or support forums for updated information or alternative solutions.
