create_instance_with_privateip.sh

###############################################################
## Script needs the below 2 parameters
## param 1 - instance_count - count of 'n' number of instances 
## param 2 - AWS account profile name - "default" or "account2"

## Example: 
## ./create_instance_with_privateip.sh 1 default
## ./create_instance_with_privateip.sh 1 account2

##
## This script can be used to create instances attached with 1 privateIP
## Script considers two AWS accounts 
## Those accounts configured with corresponding profile names "default" and "account2"
