BLOB Storing Azure Provider can store BLOBs in [Azure Blob storage](https://azure.microsoft.com/en-us/services/storage/blobs/).
> Read the [BLOB Storing document](Blob-Storing.md) to understand how to use the BLOB storing system. This document only covers how to configure containers to use a Azure blob as the storage provider.

## Installation
You can use dotnet cli to install [the package](https://www.nuget.org/packages/Volo.Abp.BlobStoring.Azure).
Use the ABP CLI to add [Volo.Abp.BlobStoring.Azure](https://www.nuget.org/packages/Volo.Abp.BlobStoring.Azure) NuGet package to your project:
````bash
dotnet add package Volo.Abp.BlobStoring.Azure
````
After installation, add `DepenedsOn` attribute of the `AbpBlobStoringAzureModule` module to your [module](Module-Development-Basics.md).
* Install the [ABP CLI](https://docs.abp.io/en/abp/latest/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.Azure` package.
* Run `abp add-package Volo.Abp.BlobStoring.Azure` command.
Whenever you add a NuGet package to a project, also add the module class dependency.
If you want to do it manually, install the [Volo.Abp.BlobStoring.Azure](https://www.nuget.org/packages/Volo.Abp.BlobStoring.Azure) NuGet package to your project and add `[DependsOn(typeof(AbpBlobStoringAzureModule))]` to the [ABP module](Module-Development-Basics.md) class inside your project.
### Configuring the Containers
## Configuration
Configuration is done in the `ConfigureServices` method of your [module](Module-Development-Basics.md) class, as explained in the [BLOB Storing document](Blob-Storing.md).
> See the [BLOB Storing document](Blob-Storing.md) to learn how to configure this provider for a specific container.
## Options
### Options
* **ConnectionString** (string): A connection string includes the authorization information required for your application to access data in an Azure Storage account at runtime using Shared Key authorization. Please refer to Azure documentation: https://docs.microsoft.com/en-us/azure/storage/common/storage-configure-connection-string
* **ContainerName** (string): You can specify the container name in azure. If it is not specified, the `ContainerName` of the `BlobProviderArgs` will be used. However, please note that Azure has some rules for naming containers. A container name must be a valid DNS name, conforming to the [following naming rules](https://docs.microsoft.com/en-us/rest/api/storageservices/naming-and-referencing-containers--blobs--and-metadata#container-names).
* Container-names 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 azure, `AzureBlobProvider` will try to create it. Please refer to the naming rules mentioned above.
* **ContainerName** (string): You can specify the container name in azure. If this is not specified, it uses the name of the BLOB container defined with the `BlogContainerName` attribute (see the [BLOB storing document](Blob-Storing.md)). Please note that Azure has some **rules for naming containers**. A container name must be a valid DNS name, conforming to the [following naming rules](https://docs.microsoft.com/en-us/rest/api/storageservices/naming-and-referencing-containers--blobs--and-metadata#container-names):
* 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 azure, `AzureBlobProvider` will try to create it.

* Appends `host` string if [current tenant](Multi-Tenancy.md) is `null` (or multi-tenancy is disabled for the container - see the [BLOB Storing document](Blob-Storing.md) to learn how to disable multi-tenancy for a container).
* Appends `tenants/<tenant-id>` string if current tenant is not `null`.
* `AzureBlobProvider` is the main service that implements the Azure BLOB storage provider, if you want to override/replace it via [dependency injection](Dependency-Injection.md) (don't replace `IBlobProvider` interface, but replace `AzureBlobProvider` class).
* `IAzureBlobNameCalculator` is used to calculate the full BLOB name (that is explained above). It is implemented by the `DefaultAzureBlobNameCalculator` by default.
