Overview
Active Storage Azure Storage Service
Wraps the Microsoft Azure Storage Blob ::ActiveStorage::Service
as an Active Storage service. See ::ActiveStorage::Service
for the generic API documentation that applies to all services.
Class Method Summary
- .new(storage_account_name:, storage_access_key:, container:, public: false, **options) ⇒ AzureStorageService constructor
::ActiveStorage::Service
- Inherited
.configure | Configure an Active Storage service by name from a set of configurations, typically loaded from a YAML file. |
.build | Override in subclasses that stitch together multiple services and hence need to build additional services using the configurator. |
