This topic describes how to use Resource Orchestration Service (ROS) to update a stack.

Prerequisites

A stack is created. For more information about how to create a stack, see Create a stack.

Background information

  • To modify only the current template and configurations of a specified stack while leaving the region unchanged, you must update the stack.
  • To modify the current template and configurations of a specified stack and the region where the stack resides, you must recreate the stack. For more information, see Recreate a stack.

Procedure

  1. Log on to the ROS console.
  2. In the left-side navigation pane, click Stacks.
  3. In the upper-left corner, select the region where the target stack resides from the drop-down list.
  4. On the Stacks page, find the stack you want to update and click Update in the Actions column.
  5. In the Configure Template Parameters step of the Edit Stack wizard, set Parameters.
    Note
    • When you update parameters of resources in the stack, ensure that these parameters can be updated. For more information, see the corresponding documentation about parameters of each resource type.
    • If you want to modify the template parameters without modifying the stack policy, click Confirm to update the stack.
  6. Click Next.
  7. In the Configure Stack step of the Edit Stack wizard, set Stack Policy, Rollback on Failure, Deletion Protection and Timeout Period.
  8. Click Confirm.
    To confirm the update configuration, click Next. After you confirm that the configuration is correct, click Confirm to update the stack.
