update-function

Description

Updates a CloudFront function.

You can update a function’s code or the comment that describes the function. You cannot update a function’s name.

To update a function, you provide the function’s name and version (ETag value) along with the updated function code. To get the name and version, you can use ListFunctions and DescribeFunction .

See also: AWS API Documentation

See ‘aws help’ for descriptions of global parameters.

Synopsis

  update-function
--name <value>
--if-match <value>
--function-config <value>
--function-code <value>
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options

--name (string)

The name of the function that you are updating.

--if-match (string)

The current version (ETag value) of the function that you are updating, which you can get using DescribeFunction .

--function-config (structure)

Configuration information about the function.

Comment -> (string)

A comment to describe the function.

Runtime -> (string)

The function’s runtime environment. The only valid value is cloudfront-js-1.0 .

Shorthand Syntax:

Comment=string,Runtime=string

JSON Syntax:

{
  "Comment": "string",
  "Runtime": "cloudfront-js-1.0"
}

--function-code (blob)

The function code. For more information about writing a CloudFront function, see Writing function code for CloudFront Functions in the Amazon CloudFront Developer Guide .

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See ‘aws help’ for descriptions of global parameters.
