Description: Install-ModuleFromGallery is a cmdlet in Windows PowerShell that allows users to install modules directly from the PowerShell Gallery, an online repository that hosts a wide variety of modules and scripts created by the community and Microsoft. This cmdlet simplifies the module management process, making it easier to search for, install, and update components that extend PowerShell’s capabilities. By using this cmdlet, administrators and developers can access additional tools and functionalities that can be crucial for task automation, system administration, and script development. The cmdlet’s syntax is intuitive, allowing users to specify the name of the module they wish to install, as well as additional options to customize the installation. The ability to install modules from the PowerShell Gallery has transformed how users interact with PowerShell, fostering a more dynamic and collaborative ecosystem where resources are easily accessible and updatable.
History: The PowerShell Gallery was launched in 2014 as part of an effort to improve module management in PowerShell. Since its inception, it has evolved into an essential resource for system administrators and developers, enabling efficient distribution and sharing of modules. Over the years, significant improvements have been made to the functionality of the Install-Module cmdlet, including the ability to handle module dependencies and versions, further facilitating its use in production environments.
Uses: The Install-ModuleFromGallery cmdlet is primarily used to install modules that extend PowerShell’s capabilities. This includes modules for system administration, task automation, and development tools. System administrators use it to quickly deploy new functionalities without the need to manually download and install each module, saving time and reducing errors.
Examples: A practical example of using Install-ModuleFromGallery is installing the ‘AzureRM’ module, which allows management of resources in cloud environments. An administrator can run the command ‘Install-Module -Name AzureRM’ to install it directly from the PowerShell Gallery, facilitating cloud service management. Another example is installing the ‘Pester’ module, which is used for testing PowerShell scripts, improving code quality.
