Variable Expansion

Notice how some config options are patterns. Like:

Ufo.configure do |config|
  config.names.stack = ":APP-:ROLE-:ENV"
  config.names.task_definition = ":APP-:ROLE-:ENV"

UFO takes the patterns and expands them to specific values. Example:

:APP-:ROLE-:ENV => demo-web-dev

Here are the available variables

Name Description
APP UFO app name. Configured by or UFO_APP
ROLE UFO role. Configured by UFO_APP. The default is web
ENV UFO env. Configured by UFO_ENV. The default is dev
REGION The current AWS_REGION, set by env var, ~/.aws/config, etc. The default is us-east-1 when it cannot be discovered.
