Function code type. Options: inline: inline code zip: ZIP file obs: function code stored in an OBS bucket jar: JAR file, mainly for Java functions Custom-Image-Swr: The function code comes from the SWR custom image.

Enumeration values:

• inline
• zip
• obs
• jar
• Custom-Image-Swr

image_name

String

Internal identifier of a function version.

xrole

String

Agency used by the function. You need to create an agency on the IAM console. This field is mandatory when a function needs to access other services. After specifying a function execution agency, you can use the context method in the function handler to obtain a token, an AK, and an SK for accessing other cloud services. No agency is required if FunctionGraph does not access any cloud services.

app_xrole

String

Execution agency. You can optimize performance by configuring a separate agency for function execution, otherwise, the same agency is used for both execution and configuration.
