Properties

AgentVersion

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

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.

Note

You can also specify an agent version when you create or update an instance, which overrides the stack's default setting.

Required: No

Type: String

Update requires: No interruption

Attributes

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

Required: No

Type: Object of String

Update requires: Replacement

ClonePermissions

If you're cloning an AWS OpsWorks stack, indicates whether to clone the source stack's permissions.

Required: No

Type: Boolean

Update requires: Replacement

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.

Required: No

Type: StackConfigurationManager

Update requires: No interruption

Required: No

Type: Source

Update requires: No interruption

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.

Required: No

Type: Json

Update requires: No interruption

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.

Required: No

Type: String

Update requires: No interruption

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.

Required: Yes

Type: String

Update requires: No interruption

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.

The default option is the current Amazon Linux version. Not all operating systems are supported with all versions of Chef. For more information about supported operating systems, see AWS OpsWorks Stacks Operating Systems.

Required: No

Type: String

Update requires: No interruption

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 isinstance-store. For more information, see Storage for the Root Device.

Required: No

Type: String

Allowed values: ebs | instance-store

Update requires: No interruption

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.

Required: No

Type: String

Update requires: No interruption

DefaultSubnetId

The stack's default subnet ID. All instances are launched into this subnet unless you specify another subnet ID when you create the instance. This parameter is required if you specify a value for theVpcId parameter. If you also specify a value forDefaultAvailabilityZone, the subnet must be in that zone.

Required: Conditional

Type: String

Update requires: No interruption

EcsClusterArn

The Amazon Resource Name (ARN) of the Amazon Elastic Container Service (Amazon ECS) cluster to register with the AWS OpsWorks stack.

Note

If you specify a cluster that's registered with another AWS OpsWorks stack, AWS CloudFormation deregisters the existing association before registering the cluster.

Required: No

Type: String

Update requires: No interruption

ElasticIps

A list of Elastic IP addresses to register with the AWS OpsWorks stack.

Note

If you specify an IP address that's registered with another AWS OpsWorks stack, AWS CloudFormation deregisters the existing association before registering the IP address.

Required: No

Type: Array of ElasticIp

Update requires: No interruption

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:

To obtain a generated host name, call GetHostNameSuggestion, which returns a host name based on the current theme.

Required: No

Type: String

Update requires: No interruption

Name

The stack name. Stack names can be a maximum of 64 characters.

Required: Yes

Type: String

Update requires: No interruption

RdsDbInstances

The Amazon Relational Database Service (Amazon RDS) database instance to register with the AWS OpsWorks stack.

Note

If you specify a database instance that's registered with another AWS OpsWorks stack, AWS CloudFormation deregisters the existing association before registering the database instance.

Required: No

Type: Array of RdsDbInstance

Update requires: No interruption

ServiceRoleArn

The stack's 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.

Required: Yes

Type: String

Update requires: Replacement

SourceStackId

Whether the stack uses custom cookbooks.

Required: No

Type: Boolean

Update requires: No interruption

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:

For more information, see Create a New Stack.

Required: No

Type: Boolean

Update requires: No interruption

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 the VPC ID corresponds to a default VPC and you have specified either theDefaultAvailabilityZone 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:

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.

Required: No

Type: String

Update requires: Replacement

Return values

Ref

When you pass the logical ID of this resource to the intrinsic Ref function, Ref returns the resource name. For example:

{ "Ref": "_myStack_" }

For the AWS OpsWorks stack myStack, Ref returns the AWS OpsWorks stack ID.

For more information about using the Ref function, see Ref.
