Description

See: http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/parameters-section-structure.html

You can use the optional Parameters section to pass values into your template when you create a stack. With parameters, you can create templates that are customized each time you create a stack. Each parameter must contain a value when you create a stack. You can specify a default value to make the parameter optional. For more information about creating stacks, see Working with Stacks.

Parameter

Fields

_parameterName :: Text
_parameterType' :: Text
The data type for the parameter.
_parameterDefault' :: Maybe Value
A value of the appropriate type for the template to use if no value is specified when a stack is created. If you define constraints for the parameter, you must specify a value that adheres to those constraints.
_parameterNoEcho :: Maybe Bool'
Whether to mask the parameter value whenever anyone makes a call that describes the stack. If you set the value to true, the parameter value is masked with asterisks (*****).
_parameterAllowedValues :: Maybe Array
An array containing the list of values allowed for the parameter.
_parameterAllowedPattern :: Maybe Text
A regular expression that represents the patterns you want to allow for String types.
_parameterMaxLength :: Maybe Integer
An integer value that determines the largest number of characters you want to allow for String types.
_parameterMinLength :: Maybe Integer
An integer value that determines the smallest number of characters you want to allow for String types.
_parameterMaxValue :: Maybe Integer
A numeric value that determines the largest numeric value you want to allow for Number types.
_parameterMinValue :: Maybe Integer
A numeric value that determines the smallest numeric value you want to allow for Number types.
_parameterDescription :: Maybe Text
A string of up to 4000 characters that describes the parameter.
_parameterConstraintDescription :: Maybe Text
A string that explains the constraint when the constraint is violated.
