publishFunction

Publishes a CloudFront function by copying the function code from the DEVELOPMENT stage to LIVE. This automatically updates all cache behaviors that are using this function to use the newly published copy in the LIVE stage.

When a function is published to the LIVE stage, you can attach the function to a distribution's cache behavior, using the function's Amazon Resource Name (ARN).

To publish a function, you must provide the function's name and version (ETag value). To get these values, you can use ListFunctions and DescribeFunction.
