BLOB Storing Google Provider

BLOB Storing Google Provider can store BLOBs in Google Cloud Storage.

Read the BLOB Storing document to understand how to use the BLOB storing system. This document only covers how to configure containers to use a Google Cloud Storage as the storage provider.

Installation

Use the ABP CLI to add Volo.Abp.BlobStoring.Google NuGet package to your project:

  • Install the ABP CLI if you haven't installed before.
  • Open a command line (terminal) in the directory of the .csproj file you want to add the Volo.Abp.BlobStoring.Google package.
  • Run abp add-package Volo.Abp.BlobStoring.Google command.

If you want to do it manually, install the Volo.Abp.BlobStoring.Google NuGet package to your project and add [DependsOn(typeof(AbpBlobStoringGoogleModule))] to the ABP module class inside your project.

Configuration

Configuration is done in the ConfigureServices method of your module class, as explained in the BLOB Storing document.

Example: Configure to use the Google storage provider by default

Configure<AbpBlobStoringOptions>(options =>
{
    options.Containers.ConfigureDefault(container =>
    {
        container.UseGoogle(google =>
        {
            google.ClientEmail = "your coogle client email";
            google.ProjectId = "your coogle project id";
            google.PrivateKey = "your coogle private key";
            google.Scopes = "your coogle scopes";
            google.ContainerName = "your coogle container name";
            google.CreateContainerIfNotExists = true;
            //google.UseApplicationDefaultCredentials = true; // If you want to use application default credentials
        });
    });
});

See the BLOB Storing document to learn how to configure this provider for a specific container.

Options

  • ClientEmail (string): The client email of the Google service account. You can create a service account and get the client email. Please refer to Google documentation: https://cloud.google.com/iam/docs/service-account-overview
  • ProjectId (string): The project ID of the Google service account.
  • PrivateKey (string): The private key of the Google service account. You can create a service account and get the private key. Please refer to Google documentation: https://cloud.google.com/iam/docs/keys-create-delete
  • Scopes (string): The scopes of the Google service account.
  • UseApplicationDefaultCredentials (bool): If true, it uses the application default credentials(ADC). Default value is false. Please refer to Google documentation: https://cloud.google.com/docs/authentication/provide-credentials-adc
  • ContainerName (string): You can specify the container name in Google. If this is not specified, it uses the name of the BLOB container defined with the BlobContainerName attribute (see the BLOB storing document). Please note that Google has some rules for naming containers. A container name must be a valid DNS name, conforming to the following naming rules:
    • Container names must start or end with a letter or number, and can contain only letters, numbers, and the dash (-) character.
    • Every dash (-) character must be immediately preceded and followed by a letter or number; consecutive dashes are not permitted in container names.
    • All letters in a container name must be lowercase.
    • Container names must be from 3 through 63 characters long.
  • CreateContainerIfNotExists (bool): Default value is false, If a container does not exist in Google, GoogleBlobProvider will try to create it.

Google Blob Name Calculator

Google Blob Provider organizes BLOB name and implements some conventions. The full name of a BLOB is determined by the following rules by default:

  • Appends host string if current tenant is null (or multi-tenancy is disabled for the container - see the BLOB Storing document to learn how to disable multi-tenancy for a container).
  • Appends tenants/<tenant-id> string if current tenant is not null.
  • Appends the BLOB name.

Other Services

  • GoogleBlobProvider is the main service that implements the Google BLOB storage provider, if you want to override/replace it via dependency injection (don't replace IBlobProvider interface, but replace GoogleBlobProvider class).
  • IGoogleBlobNameCalculator is used to calculate the full BLOB name (that is explained above). It is implemented by the DefaultGoogleBlobNameCalculator by default.
