Syntax

To declare this entity in your AWS CloudFormation template, use the following syntax:

JSON

{ "Type" : "AWS::OpsWorks::Stack", "Properties" : { "AgentVersion" : String, "Attributes" : {Key : Value, ...}, "ChefConfiguration" : ChefConfiguration, "CloneAppIds" : [ String, ... ], "ClonePermissions" : Boolean, "ConfigurationManager" : StackConfigurationManager, "CustomCookbooksSource" : Source, "CustomJson" : Json, "DefaultAvailabilityZone" : String, "DefaultInstanceProfileArn" : String, "DefaultOs" : String, "DefaultRootDeviceType" : String, "DefaultSshKeyName" : String, "DefaultSubnetId" : String, "EcsClusterArn" : String, "ElasticIps" : [ ElasticIp, ... ], "HostnameTheme" : String, "Name" : String, "RdsDbInstances" : [ RdsDbInstance, ... ], "ServiceRoleArn" : String, "SourceStackId" : String, "Tags" : [ Tag, ... ], "UseCustomCookbooks" : Boolean, "UseOpsworksSecurityGroups" : Boolean, "VpcId" : String } }

Properties

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.

Note

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

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 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: List 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:

Type: String

Update requires: No interruption

RdsDbInstances

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

Required: No

Type: List of RdsDbInstance

Update requires: No interruption

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.

Required: Yes

Type: String

Update requires: Replacement

SourceStackId

If you're cloning an AWS OpsWorks stack, the stack ID of the source AWS OpsWorks stack to clone.

Required: No

Tags

A map that contains tag keys and tag values that are attached to a stack or layer.

  • The key cannot be empty.

  • The key can be a maximum of 127 characters, and can contain only Unicode letters, numbers, or separators, or the following special characters: + - = . _ : /

  • The value can be a maximum 255 characters, and contain only Unicode letters, numbers, or separators, or the following special characters: + - = . _ : /

  • Leading and trailing white spaces are trimmed from both the key and value.

  • A maximum of 40 tags is allowed for any resource.

Required: No

Type: List of Tag

Update requires: No interruption

UseCustomCookbooks

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:

  • 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.

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 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.

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.

Examples
