Configure a custom BLOB provider

1 min

Custom BLOB providers let you direct binary storage to your preferred backend, such as Azure or AWS, instead of the default file system.

Add a BlobProviders section in appsettings.json under the episerver/cms element to define a custom provider:

{
  "EPiServer": {
    "Cms": {
      "BlobProviders": {
        "DefaultProvider": "Custom",
        "Providers": {
          "Custom": "CustomProvider, Customassembly",
          "Another": "Another_CustomProvider, Customassembly"
        }
      }
    }
  }
}

Add the BLOB provider programmatically during the site configuration phase by using IServiceCollection or by configuring the BlobProvidersOptions class directly.

public void ConfigureServices(IServiceCollection services) {
  // This provider will be added as the default
  services.AddFileBlobProvider("myFileBlobProvider", @ "c:\path\to\file\blobs");
  services.AddBlobProvider<MyCustomBlobProvider>("myCustomBlobProvider", defaultProvider: false);
  services.Configure<BlobProvidersOptions>(o => {
    o.AddProvider<MyCustomBlobProvider>("anotherCustomBlobProvider");
    o.DefaultProvider = "anotherCustomBlobProvider";
  });
}
