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

• 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
