Constructor Details

#initialize(options = {}, &block) ⇒ Azure::Storage::Common::Client

Public: Creates an instance of [Azure::Storage::Common::Client]

Attributes

  • options - Hash. Optional parameters.

Options

Accepted key/value pairs in options parameter are:

  • :use_development_storage - TrueClass|FalseClass. Whether to use storage emulator.

  • :development_storage_proxy_uri - String. Used with :use_development_storage if emulator is hosted other than localhost.

  • :storage_connection_string - String. The storage connection string.

  • :storage_account_name - String. The name of the storage account.

  • :storage_access_key - Base64 String. The access key of the storage account.

  • :storage_sas_token - String. The signed access signature for the storage account or one of its service.

  • :storage_blob_host - String. Specified Blob serivce endpoint or hostname

  • :storage_table_host - String. Specified Table serivce endpoint or hostname

  • :storage_queue_host - String. Specified Queue serivce endpoint or hostname

  • :storage_dns_suffix - String. The suffix of a regional Storage Serivce, to

  • :default_endpoints_protocol - String. http or https

  • :use_path_style_uri - String. Whether use path style URI for specified endpoints

  • :ca_file - String. File path of the CA file if having issue with SSL

  • :user_agent_prefix - String. The user agent prefix that can identify the application calls the library

The valid set of options include:

  • Storage Emulator: :use_development_storage required, :development_storage_proxy_uri optionally

  • Storage account name and key: :storage_account_name and :storage_access_key required, set :storage_dns_suffix necessarily

  • Storage account name and SAS token: :storage_account_name and :storage_sas_token required, set :storage_dns_suffix necessarily

  • Specified hosts and SAS token: At least one of the service host and SAS token. It’s up to user to ensure the SAS token is suitable for the serivce

  • Anonymous Blob: only :storage_blob_host, if it is to only access blobs within a container

Additional notes:

  • Specified hosts can be set when use account name with access key or sas token

  • :default_endpoints_protocol can be set if the scheme is not specified in hosts

  • Storage emulator always use path style URI

  • :ca_file is independent.

When empty options are given, it will try to read settings from Environment Variables. Refer to [Azure::Storage::Common::ClientOptions.env_vars_mapping] for the mapping relationship
