When you create a stack group, you can specify accounts and regions for stack instances.
This way, stacks that correspond to the stack instances are automatically deployed
within the accounts in the regions. If you specify accounts and regions for the stack
instances, the stack instances are automatically created within the accounts in the
regions. You can also use other methods to create stack instances to deploy stacks.
Procedure
- Log on to the Resource Orchestration Service (ROS) console with the management account or a delegated administrator account.
Note The logon account must be the same as the account within which you create the stack
group.
- In the left-side navigation pane, click Stack Groups.
- In the upper-left corner, select the region where the stack group is deployed from
the region drop-down list.
- On the Stack Groups page, find the stack group, click
and then choose Create Stack Instance in the Actions column.
- In the Set Deployment Options step, configure the following parameters and click Next.
Parameter |
Description |
Resource Directories |
The resource directory in which you can select a folder to deploy stacks in all member
accounts in the folder.
If you select the Root folder, ROS deploys the stacks within all the member accounts
in the resource directory.
|
Regions |
The regions where you want to deploy stacks. |
Maximum Number of Concurrent Accounts |
The maximum number of accounts within which multiple stacks are deployed at a time
in each region.
For more information about how to specify Maximum Number of Concurrent Accounts, see
Stack group deployment options.
|
Fault Tolerance |
The maximum number of accounts within which stack operation failures can occur in
each region. When the value is exceeded, ROS stops the operation in the region. If
ROS stops the operation in one region, ROS stops the operation in other regions.
For more information about how to specify Fault Tolerance, see Stack group deployment options.

- In the Specify Override Settings step, select the parameters that you want to override, use one of the following methods
to reset the parameter values, and then click Next.
- Method 1: Choose to reset the parameter values.
- Method 2: Choose to reset the parameter values.
Note After the stack instances are created, you can perform the following operations to
view the reset parameter values: Log on to the ROS console with the execution account.
On the Stacks page, click the ID of the stack for which you want to view the parameter values.
On the Parameters tab, view the parameter values.
- In the Check and Confirm step, check that the stack instance parameters are valid and click Add.
What to do next
After you create the stack instances, you can perform the following operations to
view the status of the stack instances that you create within the member accounts:
On the Stack Groups page, click the name of the stack group in which the stack instances are created.
On the Instances tab, view the status of the stack instances.
When the stacks are being deployed, the stack instances are in the Expired state. After the stacks are deployed, the stack instances enter the Current state. In this case, you can log on to the ROS console with the member accounts to
view the stacks in the specified regions. For more information about how to log on
to the ROS console with member accounts, see Access a member.
