Parameters

  • FunctionName <~String> - existing Lambda function name whose code you want to replace.

  • S3Bucket <~String> - Amazon S3 bucket name where the .zip file containing your deployment package is stored.

  • S3Key <~String> - Amazon S3 object (the deployment package) key name you want to upload.

  • S3ObjectVersion <~String> - Amazon S3 object (the deployment package) version you want to upload.

  • ZipFile <~String> - Based64-encoded .zip file containing your packaged source code.

Returns

  • response<~Excon::Response>:

    • body<~Hash>:

      • ‘CodeSize’ <~Integer> - size, in bytes, of the function .zip file you uploaded.

      • ‘FunctionArn’ <~String> - Amazon Resource Name (ARN) assigned to the function.

      • ‘FunctionName’ <~String> - name of the function.

      • ‘Handler’ <~String> - function Lambda calls to begin executing your function.

      • ‘LastModified’ <~Time> - timestamp of the last time you updated the function.

      • ‘Memorysize’ <~String> - memory size, in MB, you configured for the function.

      • ‘Role’ <~String> - ARN of the IAM role that Lambda assumes when it executes your function to access any other AWS resources.

      • ‘Runtime’ <~String> - runtime environment for the Lambda function.

      • ‘Timeout’ <~Integer> - function execution time at which Lambda should terminate the function.
