BLOB Storing Minio Provider

BLOB Storing Minio Provider can store BLOBs in MinIO Object 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 Minio BLOB as the storage provider.


Use the ABP CLI to add Volo.Abp.BlobStoring.Minio 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.Minio package.
  • Run abp add-package Volo.Abp.BlobStoring.Minio command.

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


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

Example: Configure to use the minio storage provider by default

Configure<AbpBlobStoringOptions>(options =>
    options.Containers.ConfigureDefault(container =>
        container.UseMinio(minio =>
            minio.EndPoint = "your minio endPoint";
            minio.AccessKey = "your minio accessKey";
            minio.SecretKey = "your minio secretKey";
            minio.BucketName = "your minio bucketName";

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


  • EndPoint (string): URL to object storage service. Please refer to MinIO Client SDK for .NET:
  • AccessKey (string): Access key is the user ID that uniquely identifies your account.
  • SecretKey (string): Secret key is the password to your account.
  • BucketName (string): You can specify the bucket name in MinIO. If this is not specified, it uses the name of the BLOB container defined with the BlobContainerName attribute (see the BLOB storing document).MinIO is the defacto standard for S3 compatibility, So MinIO has some rules for naming bucket. The following rules apply for naming MinIO buckets:
    • Bucket names must be between 3 and 63 characters long.
    • Bucket names can consist only of lowercase letters, numbers, dots (.), and hyphens (-).
    • Bucket names must begin and end with a letter or number.
    • Bucket names must not be formatted as an IP address (for example,
    • Bucket names can't begin with xn-- (for buckets created after February 2020).
    • Bucket names must be unique within a partition.
    • Buckets used with Amazon S3 Transfer Acceleration can't have dots (.) in their names. For more information about transfer acceleration, see Amazon S3 Transfer Acceleration.
  • WithSSL (bool): Default value is false,Chain to MinIO Client object to use https instead of http.
  • CreateContainerIfNotExists (bool): Default value is false, If a bucket does not exist in minio, MinioBlobProvider will try to create it.

Minio Blob Name Calculator

Minio 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

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