Demo application using Vert.x and GraalVM

Vertx Graal Native Image Demo Application

This is a project which uses GraalVM to build a native image of a basic Vert.x application.

For comparison, the application can also be containerized by using Jib.

The Application

This repository contains the source code for running a basic Vert.x application with as few Verticles as possible. The idea is to provide configuration examples to illustrate various aspects of configuring the application.

What is illustrated in this application?

• Basic Vert.x application.
• Logging configuration via Logback.
• External Override of Logback configuration.
• External and Dyanmic configuration file reload.
• Native executable binary.
• Containerization

What is not included in this application?

• Setting Gabage collector
  • G1 collector is not yet supported on MacOS arm64.

What is the catch?

• No cross-compile support.
  • Have to use machines with different OS and platforms to build the native image for each OS/platform.
