MONAI Deploy Storage

The MONAI Deploy Storage library for MONAI Deploy clinical data pipelines system enables users to extend the system to external storage services by implementing the IStorageService API, which allows the users to plug in any other storage services, such as AWS S3 and Azure Blob Storage.

Currently supported storage services:

• MinIO*
• Amazon S3

* Services provided may not be free or requires special license agreements. Please refer to the service providers' website for additional terms and conditions.

If you would like to use a storage service provider not listed above, please file an issue and contribute to the repository.

Installation

1. Configure the Service

To use the MONAI Deploy Storage library, install the NuGet.Org package and call the AddMonaiDeployStorageService(...) method to register the dependencies:

Host.CreateDefaultBuilder(args)
    .ConfigureServices((hostContext, services) =>
    {
        ...
        services.AddMonaiDeployStorageService(hostContext.Configuration.GetSection("InformaticsGateway:storage:serviceAssemblyName").Value);
        ...
    });

2. Install the Plug-in

1. Create a subdirectory named plug-ins in the directory where your main application is installed.
2. Download the zipped plug-in of your choice and extract the files to the plug-ins directory.
3. Update appsettings.json and set the serviceAssemblyName, e.g.:

    "storage": {
      "serviceAssemblyName": "Monai.Deploy.Storage.MinIo.MinIoStorageService, Monai.Deploy.Storage.MinIO"
    }

3. Restrict Access to the Plug-ins Directory

To avoid tampering of the plug-ins, it is recommended to set access rights to the plug-ins directory.

Writing Your Plug-in

To extend MONAI Deploy with your custom storage service provider, you must implement the IStorageService interface and extend the ServiceRegistrationBase base class.

• The IStorageService interface provides a set of methods required to interact with the storage layer.
• The ServiceRegistrationBase base class provides an abstract method Configure() to configure service dependencies based on .NET Dependency injection. The derived instance is dynamically activated during runtime based on the ServiceAssemblyName value defined in the StorageServiceConfiguration.
