Prerequisites

On your local computer

• Java 16: programming language used for this tutorial
• Maven 3: classical build and dependencies tools for Java
• Git: version control system for collaborative coding
• Docker: container framework used to create turn-key applications
• Heroku CLI tools: to manually deploy to Heroku

On external services

• GitHub account: https://github.com/join
  • to host our code and execute the CI/CD pipeline
• Docker Hub account: https://hub.docker.com/signup
  • to store our Docker image publicly (release)
• Heroku account: https://signup.heroku.com/
  • to host our running aplication (deployment)

Tutorial Outline

• Act I: Building the Technical Environment
• Act II: Creating Acceptance Scenarios
• Act III: Containerizing the application as a REST service
• Act IV: Continuous Integration & Deployment
• Act V: Pipeline in Action

Disclaimer

• The objective of this tutorial is to focus onn acceptance scenarios & technical pipeline. Thus, we took some liberty with a "proper" object orientation of REST good practices.
• DevOps is way much more than acceptance testing and CI/CD. We only had today a quick overview focused on what is possible at the technical level. The other side of DevOps, more human-centered, cannot fit in a half-day workshop.
