DELL ThinOS 10.x App Builder User Guide

Overview of App Builder

App Builder is a specialized feature for Dell ThinOS 10.x devices that allows IT administrators and developers to create, customize, and deploy Customer-Installed (CI) application packages. This tool provides a secure environment for integrating third-party or custom software into the ThinOS ecosystem. It operates exclusively in Enhanced Mode, which unlocks advanced security and customization capabilities.

Deployment Modes

App Builder supports two primary deployment modes to manage how applications interact with the operating system:

• Isolated Mode (Recommended): Runs applications in a secure, containerized environment. This approach ensures system stability and prevents conflicts with the base ThinOS operating system.
• Native Mode: Executes applications directly on the ThinOS OS. This mode provides full system access but carries a higher risk of dependency conflicts and security exposure. It is intended only for trusted, production-ready applications that have undergone Dell whitelisting.

Environment Setup

Before using App Builder, the environment must be properly configured. This involves enabling Enhanced Mode on the ThinOS device, which is a prerequisite for all App Builder functions. Administrators must also install the CI Software Enabler and the App Builder package using Wyse Management Suite (WMS) or the Admin Policy Tool (APT). Ensure that the device meets the minimum hardware requirements, including at least 4 GB of RAM and 32 GB of secondary storage.

Application Packaging and Deployment

The packaging process involves defining application details, resolving dependencies, and setting specific permissions for peripherals such as webcams, microphones, and USB devices. Once the package is built, it must be signed with a valid certificate to ensure secure deployment. After signing, the package can be deployed across managed devices using WMS or APT. The system also provides tools for certificate management, allowing users to generate SSL certificates and private keys using OpenSSL or IIS.

Maintenance and Troubleshooting

If issues arise during deployment, administrators can use the built-in logs and reports within App Builder to identify errors. Common problems often relate to missing dependencies or incorrect peripheral permissions. If an application fails to run, it is recommended to verify the deployment mode and reconfigure permissions. For complete removal of CI applications, administrators can perform a Soft Reset to clear packages while retaining user settings, or a Hard Reset to restore the device to its factory state.
