Example: Post-provision cloud script

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

Avant de commencer

• 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.

Pourquoi et quand exécuter cette tâche

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

Procédure

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.

      

3. Publish the virtual server resource block, and use it in a blueprint that in turn is published to a catalog item.
4. Launch a new stack to provision a VM and specify the OS profile and Compute profile that you created as a prerequisite.

Résultats

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