Hey there, Gurus! Welcome to the lab. Here’s the scenario! You are an admin working at the ZLand BioTech firm where you are in charge of creating early screening software that is going to revolutionize the industry for tracking symptoms of the dreaded Virus Z-19. This software is vital to the early warning system and tracking of the virus. Your job is to assist the developers in managing and creating the applications that make up the screening and tracking software. You are being asked to create a new project called Snowball. The developers are wanting a Ruby environment with a Postgresql database to create a micro-service for the tracking app. They would like you to create the environment by using the “rails-postgresql-example” template. The lead on this gave you the database and user info for the database. Create a parameters file with the database information and pass it through to the command when using the template to create the objects in your project. Let’s begin!
>**Note:** This lab is meant to be run on your local environment. This will not work in our Playground or Lab environment currently.
