Lazybone Dropwizard Turbo template

Turbo charge your Dropwizard 0.8.0 Microservice using this lazybones template, inspired by KyleBoon's Lazybones Template for Dropwizard 0.7.0

For more instructions on lazybones( Project Creation tool) and how to build this project refer to: Lazy Bones and Template developer guide

Purpose

There are many Dropwizard Modules available to extend from. However sometimes it may be difficult for all modules to play well together. This templates aims to pull together various essential modules we came across in our day to day projects and present them as a stable integrated bundle together with unit/integration tests.

The resultant project is tailored towards the following usages (see Tech Stack below for more details):

• dependency injection - use Guice auto config to avoid boilerplate code.
• containerised deployment - Docker or Heroku containers: single port and ENV variables available during runtime only
• continuous delivery - application version is not hardcoded but passed in at build time via gradle property: -Papp_version
• Java8 - lambdas, Optional and LocalDate.

The result project will also mark certain modules and dependencies as optional, they can be deleted based on your needs.

Usage

Install lazybones using gvm

gvm install lazybones

Update lazybones config to point to trunkplatform lazybones repository:

lazybones config set bintrayRepositories "pledbrook/lazybones-templates", "trunkplatform/lazybones"
