Chef Bootstrapping an EC2 instance immediately and handsfree using cloud-init user-data

user-data.txt

#cloud-config
#
# This is an example file to automatically install chef-client and run a
# list of recipes when the instance boots for the first time.
# Make sure that this file is valid yaml before starting instances.
# It should be passed as user-data when starting the instance.
#
# This example assumes the instance is 16.04 (xenial)


# The default is to install from packages.

# Key from https://packages.chef.io/chef.asc
