Creates a new stack. For more information, see Create a New Stack.

Required Permissions: To use this action, an IAM user must have an attached policy that explicitly grants permissions. For more information about user permissions, see Managing User Permissions.

May throw ValidationException.

Parameter defaultInstanceProfileArn : The Amazon Resource Name (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 Using Identifiers.

Parameter name : The stack name.

Parameter region : The stack's AWS region, such as ap-south-1. For more information about Amazon regions, see Regions and Endpoints.

Parameter serviceRoleArn : The stack's AWS Identity and Access Management (IAM) role, which allows AWS OpsWorks Stacks to work with AWS resources on your behalf. You must set this parameter to the Amazon Resource Name (ARN) for an existing IAM role. For more information about IAM ARNs, see Using Identifiers.

Parameter agentVersion : The default AWS OpsWorks Stacks agent version. You have the following options:

  • Auto-update - Set this parameter to LATEST. AWS OpsWorks Stacks 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 Stacks then automatically installs that version on the stack's instances.
The default setting is the most recent release of the agent. 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. AgentVersion cannot be set to Chef 12.2.

Parameter attributes : One or more user-defined key-value pairs to be added to the stack attributes.

Parameter chefConfiguration : A ChefConfiguration object that specifies whether to enable Berkshelf and the Berkshelf version on Chef 11.10 stacks. For more information, see Create a New Stack.

Parameter configurationManager : The configuration manager. When you create a stack we recommend that you use the configuration manager to specify the Chef version: 12, 11.10, or 11.4 for Linux stacks, or 12.2 for Windows stacks. The default value for Linux stacks is currently 12.

Parameter customCookbooksSource : Contains the information required to retrieve an app or cookbook from a repository. For more information, see Adding Apps or Cookbooks and Recipes.

Parameter customJson : A string that contains user-defined, custom JSON. It can be used to override the corresponding default stack configuration attribute values or to pass data to recipes. The string should be in the following format:

"{"key1": "value1", "key2": "value2",...}"

For more information about custom JSON, see Use Custom JSON to Modify the Stack Configuration Attributes.

Parameter defaultAvailabilityZone : The stack's default Availability Zone, which must be in the specified region. For more information, see Regions and Endpoints. If you also specify a value for DefaultSubnetId, the subnet must be in the same zone. For more information, see the VpcId parameter description.

Parameter defaultOs : The stack's default operating system, which is installed on every instance unless you specify a different operating system when you create the instance. You can specify one of the following.

  • A supported Linux operating system: An Amazon Linux version, such as Amazon Linux 2018.03, Amazon Linux 2017.09, Amazon Linux 2017.03, Amazon Linux 2016.09, Amazon Linux 2016.03, Amazon Linux 2015.09, or Amazon Linux 2015.03.
  • A supported Ubuntu operating system, such as Ubuntu 16.04 LTS, Ubuntu 14.04 LTS, or Ubuntu 12.04 LTS.
  • CentOS Linux 7
  • Red Hat Enterprise Linux 7
  • A supported Windows operating system, such as Microsoft Windows Server 2012 R2 Base, Microsoft Windows Server 2012 R2 with SQL Server Express, Microsoft Windows Server 2012 R2 with SQL Server Standard, or Microsoft Windows Server 2012 R2 with SQL Server Web.
  • A custom AMI: Custom. You specify the custom AMI you want to use when you create instances. For more information, see Using Custom AMIs.
The default option is the current Amazon Linux version. For more information about supported operating systems, see AWS OpsWorks Stacks Operating Systems.

Parameter defaultRootDeviceType : The default root device type. This value is the default for all instances in the stack, but you can override it when you create an instance. The default option is instance-store. For more information, see Storage for the Root Device.

Parameter defaultSshKeyName : 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 Using SSH to Communicate with an Instance and Managing SSH Access. You can override this setting by specifying a different key pair, or no key pair, when you create an instance.

Parameter defaultSubnetId : 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.

Parameter hostnameTheme : The stack's 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_and_Titans
  • 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.

Parameter useCustomCookbooks : Whether the stack uses custom cookbooks.

Parameter useOpsworksSecurityGroups : Whether to associate the AWS OpsWorks Stacks built-in security groups with the stack's layers.

AWS OpsWorks Stacks provides a standard set of built-in security groups, one for each layer, which are associated with layers by default. With UseOpsworksSecurityGroups you can instead provide your own custom security groups. UseOpsworksSecurityGroups has the following settings:

  • True - AWS OpsWorks Stacks 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 Stacks 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 creation; custom security groups are required only for those layers that need custom settings.
For more information, see Create a New Stack.

Parameter vpcId : The ID of the VPC that the stack is to be launched into. The VPC must be in the stack's region. All instances are launched into this VPC. You cannot change the ID later.

  • If your account supports EC2-Classic, the default value is no VPC.
  • If your account does not support EC2-Classic, the default value is the default VPC for the specified region.
If the VPC ID corresponds to a default VPC and you have specified either the DefaultAvailabilityZone or the DefaultSubnetId parameter only, AWS OpsWorks Stacks infers the value of the other parameter. If you specify neither parameter, AWS OpsWorks Stacks sets these parameters to the first valid Availability Zone for the specified region and the corresponding default VPC subnet ID, respectively.

If you specify a nondefault VPC ID, note the following:

  • It must belong to a VPC in your account that is in the specified region.
  • You must specify a value for DefaultSubnetId.
For more information about how to use AWS OpsWorks Stacks with a VPC, see Running a Stack in a VPC. For more information about default VPC and EC2-Classic, see Supported Platforms.
