  • user_data (string) - User data to apply when launching the instance. Note that you need to be careful about escaping characters due to the templates being JSON. It is often more convenient to use user_data_file, instead. Packer will not automatically wait for a user script to finish before shutting down the instance this must be handled in a provisioner.

  • user_data_file (string) - Path to a file that will be used for the user data when launching the instance.

  • vpc_cidr_block (string) - Value options: 192.168.0.0/16 and 172.16.0.0/16. When not specified, the default value is 172.16.0.0/16.
