Terraform Beginner Bootcamp 2023 - Week 2

Terraform Mock Server

Running The Web Server

  • Upon initialization of our Gitpod environment, we enabled the Sinatra Web Server to start in the gitpod.yml file, Gitpod Documentation, Close workspace, Restart workspace.
  • We run the web serveer by manually by executing the command bundle exec ruby server.rb.
  • All of the code for our server is stored in the server.rb file.

Working With Ruby

Bundler

Bundler is a package manager for Ruby, it is the primary way to install Ruby packages(known as gems) for Ruby.

Install Gems

  • You need to create a Gemfile and define your gems in that file.
source "https://rubygems.org"

gem 'sinatra'
gem 'rake'
gem 'pry'
gem 'puma'
gem 'activerecord'
  • Then you run the bundle install command--(more like npm install), this will install the gems on the system globally(unlike nodejs which install packages in a node_modules directory).

Executing Ruby Scripts In the Context of Bundler

  • Use bundle exec to install future Ruby scripts, the command uses the gems we already installed.

Sinatra

  • Sinatra is a micro web-framework for Ruby to build web-apps.
  • Its great for mock or development servers/simple projects.
  • You can create a web-server in a single file.
  • Sinatra Reference.
