Managing a Stack
================

Stack management consists of two aspects. One is lifecycle management of created stacks, including deleting and changing. The other is viewing stack details to obtain their running statuses.

Modifying a Stack
-----------------

After a stack is created successfully (that is, in the normal status), you can change the parameters of the stack as needed.

#. Log in to the RFS console.

#. In the navigation pane on the left, click **Stacks**.

#. In the stack list, click the stack to be changed.

#. On the stack details page, click **Update Template/Parameter**.

#. Change the template version or input parameters, and click **Next**.

#. Confirm the configurations and then click **Create Execution Plan**.

#. On the **Execution Plans** tab page of the stack details page, select the created execution plan and click **Deploy** in the **Operation** column.

   On the **Events** tab page, you can view the detailed operation events related to stack changes.

Deleting a Stack
----------------

Deleted stacks cannot be restored. Exercise caution when deleting a stack.

#. Log in to the RFS console.

#. In the navigation pane on the left, click **Stacks**.

#. In the stack list, select the stack to be deleted and click **Delete** in the **Operation** column.

#. In the dialog box displayed, enter **Delete** and click **OK**.

   Check the stack name carefully. The deletion cannot be revoked.

   On the **Events** tab page, you can view the detailed operation events related to stack deletion.

Viewing Stack Details
---------------------

After a stack is created, you can view its data and resources on the stack details page.

-  Resources

   Elements of a stack, such as applications and cloud services

-  Outputs

   Output parameters and their values in the stack template

-  Template

   Details of the template used to create the stack

-  Events

   You can view stack events to monitor the stack operation progress. For example, when you create a stack, all important steps during the stack creation are displayed on the **Events** tab page. The events are sorted in chronological order with the latest event being displayed at the top.
