-- | The ARN of an IAM profile that is the default profile for all of the
-- stack\'s EC2 instances. For more information about IAM ARNs, see
-- <http://docs.aws.amazon.com/IAM/latest/UserGuide/Using_Identifiers.html Using Identifiers>.
usDefaultInstanceProfileARN :: Lens' UpdateStack (Maybe Text)
usDefaultInstanceProfileARN = lens _usDefaultInstanceProfileARN (\ s a -> s{_usDefaultInstanceProfileARN = a});

-- | Do not use this parameter. You cannot update a stack\'s service role.
usServiceRoleARN :: Lens' UpdateStack (Maybe Text)
usServiceRoleARN = lens _usServiceRoleARN (\ s a -> s{_usServiceRoleARN = a});

-- | The default root device type. This value is used by default for all
-- instances in the stack, but you can override it when you create an
-- instance. For more information, see
-- <http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ComponentsAMIs.html#storage-for-the-root-device Storage for the Root Device>.
usDefaultRootDeviceType :: Lens' UpdateStack (Maybe RootDeviceType)
usDefaultRootDeviceType = lens _usDefaultRootDeviceType (\ s a -> s{_usDefaultRootDeviceType = a});

-- | A 'ChefConfiguration' object that specifies whether to enable Berkshelf
-- and the Berkshelf version on Chef 11.10 stacks. For more information,
-- see
-- <http://docs.aws.amazon.com/opsworks/latest/userguide/workingstacks-creating.html Create a New Stack>.
usChefConfiguration :: Lens' UpdateStack (Maybe ChefConfiguration)
usChefConfiguration = lens _usChefConfiguration (\ s a -> s{_usChefConfiguration = a});

-- | The default AWS OpsWorks agent version. You have the following options:
--
-- -   Auto-update - Set this parameter to 'LATEST'. AWS OpsWorks
--     automatically installs new agent versions on the stack\'s instances
--     as soon as they are available.
-- -   Fixed version - Set this parameter to your preferred agent version.
--     To update the agent version, you must edit the stack configuration
--     and specify a new version. AWS OpsWorks then automatically installs
--     that version on the stack\'s instances.
--
-- The default setting is 'LATEST'. To specify an agent version, you must
-- use the complete version number, not the abbreviated number shown on the
-- console. For a list of available agent version numbers, call
-- DescribeAgentVersions.
--
-- You can also specify an agent version when you create or update an
-- instance, which overrides the stack\'s default setting.
usAgentVersion :: Lens' UpdateStack (Maybe Text)
usAgentVersion = lens _usAgentVersion (\ s a -> s{_usAgentVersion = a});

-- | A default Amazon EC2 key-pair name. The default value is 'none'. If you
-- specify a key-pair name, AWS OpsWorks installs the public key on the
-- instance and you can use the private key with an SSH client to log in to
-- the instance. For more information, see
-- <http://docs.aws.amazon.com/opsworks/latest/userguide/workinginstances-ssh.html Using SSH to Communicate with an Instance>
-- and
-- <http://docs.aws.amazon.com/opsworks/latest/userguide/security-ssh-access.html Managing SSH Access>.
-- You can override this setting by specifying a different key pair, or no
-- key pair, when you
-- <http://docs.aws.amazon.com/opsworks/latest/userguide/workinginstances-add.html create an instance>.
usDefaultSSHKeyName :: Lens' UpdateStack (Maybe Text)

-- | A string that contains user-defined, custom JSON. It can be used to
-- override the corresponding default stack configuration JSON values or to
-- pass data to recipes. The string should be in the following format and
-- escape characters such as \'\"\':
--
-- '\"{\\\"key1\\\": \\\"value1\\\", \\\"key2\\\": \\\"value2\\\",...}\"'
--
-- For more information on custom JSON, see
-- <http://docs.aws.amazon.com/opsworks/latest/userguide/workingstacks-json.html Use Custom JSON to Modify the Stack Configuration Attributes>.
usCustomJSON :: Lens' UpdateStack (Maybe Text)
usCustomJSON = lens _usCustomJSON (\ s a -> s{_usCustomJSON = a});

-- | Undocumented member.
usCustomCookbooksSource :: Lens' UpdateStack (Maybe Source)
usCustomCookbooksSource = lens _usCustomCookbooksSource (\ s a -> s{_usCustomCookbooksSource = a});

-- | The stack\'s default Availability Zone, which must be in the stack\'s
-- region. For more information, see
-- <http://docs.aws.amazon.com/general/latest/gr/rande.html Regions and Endpoints>.
-- If you also specify a value for 'DefaultSubnetId', the subnet must be in
-- the same zone. For more information, see CreateStack.
usDefaultAvailabilityZone :: Lens' UpdateStack (Maybe Text)
usDefaultAvailabilityZone = lens _usDefaultAvailabilityZone (\ s a -> s{_usDefaultAvailabilityZone = a});

-- | The stack\'s new name.
usName :: Lens' UpdateStack (Maybe Text)
usName = lens _usName (\ s a -> s{_usName = a});

-- | Whether to associate the AWS OpsWorks built-in security groups with the
-- stack\'s layers.
--
-- AWS OpsWorks provides a standard set of built-in security groups, one
-- for each layer, which are associated with layers by default.
-- 'UseOpsworksSecurityGroups' allows you to provide your own custom
-- security groups instead of using the built-in groups.
-- 'UseOpsworksSecurityGroups' has the following settings:
--
-- -   True - AWS OpsWorks automatically associates the appropriate
--     built-in security group with each layer (default setting). You can
--     associate additional security groups with a layer after you create
--     it, but you cannot delete the built-in security group.
-- -   False - AWS OpsWorks does not associate built-in security groups
--     with layers. You must create appropriate EC2 security groups and
--     associate a security group with each layer that you create. However,
--     you can still manually associate a built-in security group with a
--     layer on. Custom security groups are required only for those layers
--     that need custom settings.
--
-- For more information, see
-- <http://docs.aws.amazon.com/opsworks/latest/userguide/workingstacks-creating.html Create a New Stack>.
usUseOpsworksSecurityGroups :: Lens' UpdateStack (Maybe Bool)
usUseOpsworksSecurityGroups = lens _usUseOpsworksSecurityGroups (\ s a -> s{_usUseOpsworksSecurityGroups = a});

-- | The stack\'s operating system, which must be set to one of the
-- following:
--
-- -   A supported Linux operating system: An Amazon Linux version, such as
--     'Amazon Linux 2015.03', 'Red Hat Enterprise Linux 7',
--     'Ubuntu 12.04 LTS', or 'Ubuntu 14.04 LTS'.
-- -   'Microsoft Windows Server 2012 R2 Base'.
-- -   A custom AMI: 'Custom'. You specify the custom AMI you want to use
--     when you create instances. For more information on how to use custom
--     AMIs with OpsWorks, see
--     <http://docs.aws.amazon.com/opsworks/latest/userguide/workinginstances-custom-ami.html Using Custom AMIs>.
--
-- The default option is the stack\'s current operating system. For more
-- information on the supported operating systems, see
-- <http://docs.aws.amazon.com/opsworks/latest/userguide/workinginstances-os.html AWS OpsWorks Operating Systems>.
usDefaultOS :: Lens' UpdateStack (Maybe Text)
usDefaultOS = lens _usDefaultOS (\ s a -> s{_usDefaultOS = a});

-- | One or more user-defined key-value pairs to be added to the stack
-- attributes.
usAttributes :: Lens' UpdateStack (HashMap StackAttributesKeys Text)
usAttributes = lens _usAttributes (\ s a -> s{_usAttributes = a}) . _Default . _Map;

-- | Whether the stack uses custom cookbooks.
usUseCustomCookbooks :: Lens' UpdateStack (Maybe Bool)
usUseCustomCookbooks = lens _usUseCustomCookbooks (\ s a -> s{_usUseCustomCookbooks = a});

-- | The stack\'s default VPC subnet ID. This parameter is required if you
-- specify a value for the 'VpcId' parameter. All instances are launched
-- into this subnet unless you specify otherwise when you create the
-- instance. If you also specify a value for 'DefaultAvailabilityZone', the
-- subnet must be in that zone. For information on default values and when
-- this parameter is required, see the 'VpcId' parameter description.
usDefaultSubnetId :: Lens' UpdateStack (Maybe Text)
usDefaultSubnetId = lens _usDefaultSubnetId (\ s a -> s{_usDefaultSubnetId = a});

-- | The configuration manager. When you clone a stack, we recommend that you
-- use the configuration manager to specify the Chef version: 0.9, 11.4, or
-- 11.10. The default value is currently 11.4.
usConfigurationManager :: Lens' UpdateStack (Maybe StackConfigurationManager)
usConfigurationManager = lens _usConfigurationManager (\ s a -> s{_usConfigurationManager = a});

-- | The stack\'s new host name theme, with spaces replaced by underscores.
-- The theme is used to generate host names for the stack\'s instances. By
-- default, 'HostnameTheme' is set to 'Layer_Dependent', which creates host
-- names by appending integers to the layer\'s short name. The other themes
-- are:
--
-- -   'Baked_Goods'
-- -   'Clouds'
-- -   'Europe_Cities'
-- -   'Fruits'
-- -   'Greek_Deities'
-- -   'Legendary_creatures_from_Japan'
-- -   'Planets_and_Moons'
-- -   'Roman_Deities'
-- -   'Scottish_Islands'
-- -   'US_Cities'
-- -   'Wild_Cats'
--
-- To obtain a generated host name, call 'GetHostNameSuggestion', which
-- returns a host name based on the current theme.
usHostnameTheme :: Lens' UpdateStack (Maybe Text)
usHostnameTheme = lens _usHostnameTheme (\ s a -> s{_usHostnameTheme = a});

-- | The stack ID.
