Example: Post-provision cloud script

This example shows a cloud script that runs after a user provisions a virtual machine.

Before you begin

• Role required: cloud_admin
• OS resource profile that is mapped to an image template. The user provisions a resource using the profile. You must add basic authentication credentials to the image.
• Compute resource profile that is mapped to a hardware type.

About this task

In this example, you create a cloud init script, customize a resource block, and provision a VM from the Cloud User Portal.

Procedure

1. Create a cloud script template and a cloud script that refers to the template.

2. Open the virtual server resource block, and then follow these steps:

   1. Set the Draft/Published switch to Draft.

2.  On the **Operations** tab, select **Virtual Server Interface** from the **Interface** list.

3.  In the **Operation** field, verify that these operations exist:

    -   **Block Until Ready**
    -   **Execute Script**: This operation tells the blueprint to run a script.

4.  Click the **Input Parameters** tab to view the inputs for each operation.

5.  On the **Steps** tab, add steps as needed.

6.  For the **Script** parameter on each step, clear the **Script** check box and change the expression in the **Mapping** column to the following text: `$(CloudScript.scripts.scriptname)`, where `scriptname` is the name of the script, not the script template, that you created earlier.

1. Publish the virtual server resource block, and use it in a blueprint that in turn is published to a catalog item.

2. Launch a new stack to provision a VM and specify the OS profile and Compute profile that you created as a prerequisite.

Result

The Stack Status page runs through the CreateNode, BlockUntilReady, and ExecuteShellScript operations. The last operation kicked off the script you created.
