Once you create a packer template file like ami.json in the current repository .

Run the following commands to validate and build the image
    - packer validate ami.json
    - packer buil ami.json

If the above steps results in success then an aws machine image will be created in aws account for which you have provided the access to this packer script

The packer Image built with the above script "ami.json" will have nodejs already installed
