  • :storage_connection_string - String. The storage connection string.

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

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

  • Azure::Storage::Common::Client: The common client used to initalize the service. This client can be initalized and used repeatedly.

  • Anonymous Table: only :storage_table_host, if it is to only access tables 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
