# Java Application Container Image with Hot-Reloading # Java Application Container Image with Hot-Reloading
This project creates a Docker image that has uses both the [Trava DCEVM](http://dcevm.github.io/) and [Hotswap Agent](http://hotswapagent.org/) and the Java JDWP debugger. The combination of these utilities allows for the hot-reloading of Java resources and classes to enable rapid application development and debugging capabilties. As a Docker image, containers can be started to facilitate development without requiring complicated installations on developer workstations. This project creates a Docker image that has uses both the [Jetbrains JDK](https://github.com/JetBrains/JetBrainsRuntime) and [Hotswap Agent](http://hotswapagent.org/) and the Java JDWP debugger. The combination of these utilities allows for the hot-reloading of Java resources and classes to enable rapid application development and debugging capabilties. As a Docker image, containers can be started to facilitate development without requiring complicated installations on developer workstations.
It is expected that containers are configured in Maven using the Fabric8 or Spotify Docker plugins. These configurations should expose the 8000 (debugger) port and any other port that the application may open. Most importantly, it should mount/bind the source code to the following possible paths.
