PowerShell Package Management - Repository vs Provider vs Source












1















I am trying to understand package management in PowerShell, and I am getting an incomplete picture. When I look at the objects PSRepository, PackageProvider, and PackageSource, they all seem to have the following relationships:




  • A PSRepository can provide zero or more PowerShell modules. A PSRepository must have one, and only one, PackageProvider. An example of a repository is PSGallery.

  • A PackageProvider can serve zero or more PSRepository objects. A PackageProvider must have one or more PackageSource objects. A PackageProvider is sometimes referred to as a "Package Manager". Some examples of package providers include NuGet, Chocolatey, or PowerShellGet.

  • A PackageSource must serve one and only one PackageProvider. Some examples of package sources include nuget.org, MyCustomVSTSFeed, or PSGallery.


I've looked at the following links, but it still doesn't provide a clear picture of how they are related.

  1. Why does a PSRepository have a
    property called PackageManagementProvider of type string
    instead of type PackageProvider?

  2. Why does a PSRepository have its own SourceLocation property, if it already has a source reference through its provider?

  3. Why is PSGallery both a PackageSource and a PSRepository?

  4. Why is PowerShellGet both the name of a module that provides access to the gallery, and the name of a PackageProvider?

  • Maybe a repository is a combination of provider and source? And sources only have a provider property because sources only work with certain providers?

  • And why does Find-Package not work with PackageSources but PSRepository locations?
