This document discusses deploying Java EE applications to Heroku using WildFly Swarm. It provides an overview of Heroku and WildFly Swarm, demonstrates deploying a sample application, and outlines the steps to deploy a Java application to Heroku via Git including creating a Heroku account, adding a buildpack and database, and using the Heroku CLI or Drone CI/CD.

- 3. Heroku • Cloud application platform • Cedar stack (Heroku managed OS image) • Ubuntu 14.04 LTS • Process model implemented via dyno manager • Dyno = Linux container • Configurations: web (HTTP only, must bind to PORT or be killed), worker (anything, except HTTP), one-off (“heroku run” command) • Types: free, hobby, standard, performance, enterprise • A process is declared in a Procfile: “<process_type>: <command>” • Heroku Elements (add-ons, buttons, buildpacks) • Different languages (Java, PHP, Python, Ruby, etc.) • Different databases • Relational: MySQL, PostgreSQL, SQLite, etc. • NoSQL: Mongo DB, Redis, etc. • Much more • Heroku CLI • Java • Different deployment models, including git and WAR • No Java EE support • Run Java processes via: java –jar *.jar General Information
- 4. WildFly Swarm • Just-enough-appserver • Construction toolkit for minimalistic Java EE runtimes based on WildFly 10.1.0 Final application server • Uberjar • Run Java EE applications via: java –jar *-swarm.jar General Information
- 5. Demo • Source code: https://github.com/satrapu/iquest-keyboards-and-mice-brasov- 2016 • CI/CD: https://drone.io/github.com/satrapu/iquest-keyboards-and-mice- brasov-2016/latest • Live application: https://iq-kam-brasov-2016.herokuapp.com/demo Deploying JEE to Heroku
- 6. Demo • On Heroku side • Create a free account • Add a new application • Add a PostgreSQL database • Setup Java specific config vars • Add Java buildpack • On developer machine • Install Heroku CLI • Install Git • Clone repo • Setup Heroku Git remote • Deploy via Git command: “git push heroku master” • Optionally, on drone.io side (replaces “git push …”) • Create a free account • Setup build with Heroku deployment • Upload SSH key to Heroku account • Click the “Build Now” button Steps
