# File 'lib/lono/cfn/help.rb', line 3 def create <<-EOL Examples: Provided that you are in a lono project and have a `my-stack` lono template definition. To create a stack you can simply run: $ lono cfn create my-stack The above command will generate and use the template in output/my-stack.json and parameters in params/my-stack.txt. The template by convention defaults to the name of the stack. In turn, the params by convention defaults to the name of the template. Here are examples of overriding the template and params name conventions. $ lono cfn create my-stack --template different1 The template used is output/different1.json and the parameters used is output/params/prod/different1.json. $ lono cfn create my-stack --params different2 The template used is output/my-stack.json and the parameters used is output/params/prod/different2.json. $ lono cfn create my-stack --template different3 --params different4 The template used is output/different3.json and the parameters used is output/params/prod/different4.json.
