This article is meant to assist Cloud Application Manager customers who want to create and manage boxes.

It explains how to use the Script box. The Script box is the type you most commonly use to define deployments. It accepts commands in Bash, PowerShell, Salt, Ansible, Chef, or Puppet. Cloud Application Manager provides Chef and Puppet public boxes to install and run recipes or manifests locally.


Cloud Application Manager Users using Application Lifecycle Management (ALM) features.


  • Access to Applications site (Application Lifecycle Management module) of Cloud Application Manager as an authorized user.

  • A provider already configured in Cloud Application Manager. See administering providers.

Creating Your First Script Box

On the Boxes page, click New > Script. Enter a name, optionally a description and other metadata.

Save to continue. Configure the deployment using events and variables.

When ready to test the configuration, click Deploy. Under the Deployment Box, search or select a deployment policy. Policies whose claims match the script box requirements will appear here.

Can not find the one you need? Then click on Create a new deployment policy box.

The easiest way to understand script boxes is to build one. Follow this tutorial to build a simple box that says Hello World.

Attach script-events to Script Box

Script boxes allow you to include scripts attached to the different lifecycle events (install, configure, start, stop, dispose). These scripts can be edited using UI editor. You can use any scripting language you prefer, as long as it is supported by the underlying instance you deploy the box to.

Script editor

you have finished editing and have saved your script, you can specify a custom timeout value in minutes for the script execution. Once you reach this value, it will trigger the abort action of the script execution. You can specify a timeout value for any script to add to the box.

Add custom timeout

Once defined, the timeout values will be propagated to all instances deployed through this box. Values in the instance can be later modified through the Lifecycle editor without affecting the box used to deploy it.

Adding Child Script Boxes

Let’s build on top of the Hello World box as an example. To set up full-scale application deployments, you need to stitch components or micro components together. You do that by stacking child boxes within a parent. In this example, we’ll stack the Hello World box within another box.

Create a new Script box and call it Greeting. Tag that it needs Linux. To learn more, see requirements and auto updates under Box Basics.

New Script Box

Now, in the code section, add a new variable of type Box. This allows the greeting box to consume the services of another. Click New in the variable section and add a box variable as shown. Set the variable name to GREETER and for the value, select the Hello World box.

New box type varible

Now that Hello World is nested in the Greeting box, we can replace Hello World box variables with values we want. To do this, expand the GREETER variable and edit (click the pencil icon) the GREETING sub variable.

Box Management page code section

Edit this to say hello to someone else.

Editing a variable

We have overwritten the original value of the GREETING variable from the Hello World box. To go back to its original value, we can click the trash can icon at the right of the pencil icon.

Note: You can quickly tell which variables values are overridden because they change from italicized to regular text.

Changed variables in Box management code view

See what we did? We consumed a box configuration and changed deployment values of the child box within the context of the parent. Remember that the original child box definition of Hello World, in this case, is not affected. When you deploy the Greeting box in this example, it also deploys the Hello World box in the same instance.

Contacting Cloud Application Manager Support

We’re sorry you’re having an issue in Cloud Application Manager. Please review the troubleshooting tips, or contact Cloud Application Manager support with details and screenshots where possible.

For issues related to API calls, send the request body along with details related to the issue.

In the case of a box error, share the box in the workspace that your organization and Cloud Application Manager can access and attach the logs.

  • Linux: SSH and locate the log at /var/log/elasticbox/elasticbox-agent.log
  • Windows: RDP into the instance to locate the log at \ProgramData\ElasticBox\Logs\elasticbox-agent.log
