data Parameter Source #

The Parameter data type.

See: newParameter smart constructor.

Constructors

Parameter'

Fields

parameterValue :: Maybe Text
The input value associated with the parameter.
resolvedValue :: Maybe Text
Read-only. The value that corresponds to a Systems Manager parameter key. This field is returned only for SSM parameter types in the template.
parameterKey :: Maybe Text
The key associated with the parameter. If you don't specify a key and value for a particular parameter, CloudFormation uses the default value that is specified in your template.
usePreviousValue :: Maybe Bool
During a stack update, use the existing parameter value that the stack is using for a given parameter key. If you specify true, do not specify a parameter value.

newParameter :: Parameter Source #

Create a value of Parameter with all optional fields omitted.

Use generic-lens or optics to modify other optional fields.

The following record fields are available, with the corresponding lenses provided for backwards compatibility:

$sel:parameterValue:Parameter', parameter_parameterValue - The input value associated with the parameter.

$sel:resolvedValue:Parameter', parameter_resolvedValue - Read-only. The value that corresponds to a Systems Manager parameter key. This field is returned only for SSM parameter types in the template.

$sel:parameterKey:Parameter', parameter_parameterKey - The key associated with the parameter. If you don't specify a key and value for a particular parameter, CloudFormation uses the default value that is specified in your template.

$sel:usePreviousValue:Parameter', parameter_usePreviousValue - During a stack update, use the existing parameter value that the stack is using for a given parameter key. If you specify true, do not specify a parameter value.

parameter_parameterValue :: Lens' Parameter (Maybe Text) Source #

The input value associated with the parameter.

parameter_resolvedValue :: Lens' Parameter (Maybe Text) Source #

Read-only. The value that corresponds to a Systems Manager parameter key. This field is returned only for SSM parameter types in the template.

parameter_parameterKey :: Lens' Parameter (Maybe Text) Source #

The key associated with the parameter. If you don't specify a key and value for a particular parameter, CloudFormation uses the default value that is specified in your template.

parameter_usePreviousValue :: Lens' Parameter (Maybe Bool) Source #

During a stack update, use the existing parameter value that the stack is using for a given parameter key. If you specify true, do not specify a parameter value.
