RegisterPSRepository

Register-PSRepository is a PowerShell cmdlet used to register a software repository for PowerShellGet and PackageManagement. By registering a repository, users enable discovery, installation, and updating of modules from that repository in addition to the default sources.

A repository is identified by a Name and a SourceLocation URL. Optional attributes commonly provided include PublishLocation, which points to the location where packages are published, and InstallationPolicy, which indicates whether modules from the repository are treated as Trusted or Untrusted by default. The cmdlet can also accept credentials if the repository requires authentication, and it integrates with the broader PowerShellGet workflow for module management.

Typical usage involves specifying the repository’s name and source location. For example:

Register-PSRepository -Name 'MyRepo' -SourceLocation 'https://myrepo.example.com/api/v2' -PublishLocation 'https://myrepo.example.com/api/v2/package' -InstallationPolicy Trusted

After registration, modules can be discovered and installed from the repository using commands such as Find-Module and Install-Module with the -Repository parameter, for instance Find-Module -Repository MyRepo and Install-Module -Repository MyRepo.

If a repository with the same name already exists, Register-PSRepository updates its settings or may prompt for confirmation, depending on the invocation and any -Force usage. Repositories registered with this cmdlet are listed and managed through Get-PSRepository and can be removed with Unregister-PSRepository.
