Tutorial EC2: lono new ec2

The first command we’ll walk through is the lono new command. Here’s the command with some output to focus on learning.

$ lono new ec2
=> Creating new project called ec2.
      create  ec2
      create  ec2/.gitignore
      create  ec2/Gemfile
      create  ec2/Guardfile
      create  ec2/README.md
      create  ec2/app/definitions/base.rb
      create  ec2/config/settings.yml
      create  ec2/welcome.txt
      create  ec2/app/helpers
      create  ec2/app/partials
      create  ec2/app/scripts
      create  ec2/app/templates
      create  ec2/app/user_data
      create  ec2/config/params
      create  ec2/config/variables
      create  ec2/output

Congrats 🎉 You have successfully created a lono project.

Cd into your project and check things out:

  cd ec2

Add and edit templates for your project.  When you are ready to launch a CloudFormation stack run:

  lono cfn create STACK_NAME

You can also get started quickly by importing other CloudFormation templates into lono.  For example:

  lono import https://s3-us-west-2.amazonaws.com/cloudformation-templates-us-west-2/EC2InstanceWithSecurityGroupSample.template --name ec2

To re-generate your templates without launching a stack, you can run:

  lono generate

The generated CloudFormation templates are in the output/templates folder.
The generated stack parameters are in the output/params folder.  Here's the command with some output filtered to focus on learning.

The new command does a few things:

  1. Generates a starter lono project structure
  2. Installs the project’s dependencies
  3. Initialized a git repository
  4. Displays a welcome message and provides some guidance on what to do next

Let’s focus on the project structure since this might be your first time looking at a lono.
