Global config

Overview

The Global Configuration Card empowers you to define a centralized JSON configuration object. This object is readily accessible by all applications running on your edge node, regardless of their origin (native, Docker container, or marketplace app). More importantly, updates to this configuration are applied instantaneously, eliminating the need to restart or rebuild your applications.

Here's what this means for you:

• Simplified Configuration Management: Manage configuration settings for all your edge applications from a single, centralized location.
• Dynamic Updates: Make configuration changes on the fly without interrupting your applications.
• Improved Efficiency: Save time and resources by avoiding application restarts or rebuilds for configuration updates.

This article will delve deeper into how to utilize the Global Configuration Card to streamline your edge application development and deployment.
