YAML Crash Course

JSON to YAML Converter

  • YAML and JSON both work for CF
    • JSON is horrible, YAML is awsome
  • Key-Value Pairs
    • Delimited by a colon ‘:’
    • Key: Value
      • Values with colons ‘:’ must be enclosed by quotes.
        • “AWS::S3::Bucket”
      • Empty sets noted with Open/Closed curly brackets
        • Tags: {}
  • Nested objects (arrays) signified by tabs (similar to Perl)
    • bill-to:
      • last-name: Roberts
      • first-name: Thomas
  • Support Arrays
    • Delimited by a minus ‘-‘ sign
  • Multi-line strings
    • Delimited by a pipe ‘|’
    • Will display ‘as is’ (auto <br/>??)
    • JSON does not include multi-line strings
  • Can include comments!
    • Delimited by the hash tag ‘#’
    • JSON does not include comments!!
