OpenShift Vert.x cartridge

This project provides a cartridge for OpenShift v2 to deploy and run Vert.x 3 applications. It simplifies the deployment process by using a fat JAR approach, where the application and its dependencies are bundled into a single executable JAR file. The cartridge handles environment-specific configurations, scaling, and clustering for Vert.x applications on the OpenShift platform.

Key Features

• Fat JAR Deployment — Applications are deployed as self-contained fat JARs, embedding all dependencies.
• OpenShift Integration — Configures Vert.x to bind to OpenShift-provided HTTP ports and addresses automatically.
• Scalability Support — Enables horizontal scaling of application instances through OpenShift's scaling features.
• Clustering — Supports Hazelcast-based clustering for scaled applications, with customizable cluster configuration.
• Environment Configuration — Allows customization of JVM parameters, Vert.x run options, and logging via environment files.
• WebSocket Handling — Manages WebSocket connections on separate ports (8000/8433) as required by OpenShift's routing.

Philosophy

The cartridge is designed to provide a seamless deployment experience for Vert.x applications on OpenShift, abstracting away platform-specific complexities while offering flexibility for advanced configurations.
