    Procedure

    1. Log on to the ROS console.

    2. In the left-side navigation pane, click Stacks.

    3. In the top navigation bar, select the region where the stack you want to update resides from the region drop-down list. For example, select China (Hangzhou).

    4. On the Stacks page, find the stack and click Update in the Actions column.

    5. In the Configure Template Parameters section of the Configure Parameters step, follow the on-screen instructions to configure the parameters.

      Note

      If you want to change the template of your stack, click Previous to go to the Select Template step. In the Prepare Template section, select Replace Current Template. After you change the template, click Next to go to the Configure Template Parameters section of the Configure Parameters step. Then, follow the on-screen instructions to configure the parameters.

    6. In the Configure Stack Settings section, follow the on-screen instructions to configure the Stack Policy, Timeout Period, RAM Role, Whether to enable replacement update, and Tags parameters based on your business requirements.

      Note

      • If you want to specify the Stack Policy parameter, you can select Input Stack Policy and enter a stack policy. This policy takes effect even if you do not configure the stack policy the next time you update the stack.

      • A stack policy is a JSON or YAML file. For more information, see Stack policies.

    7. (Optional) Click Next to go to the Check and Confirm step. In this step, check and confirm the configurations that you update.

    8. Click Confirm.
