Exercise 2 - Introduction

The goal of this exercise is to automate the whole release and release publishing process of the project-automation chatbot application that you developed in the last course exercise as a class.

What You learn

• Build a docker image for your application
• Publish docker images to dockerhub
• Automate building and releasing a docker image with gradle
• Automatically calculate your application's version using gradle and git
• Integrate the automated release into your jenkins pipelines
• Push-button-Release: Let the Pipeline do the tagging of a clean release for you
• Test your released docker images with Play-with-Docker.com

How to Work

• Pair Programming rocks! It is proven to be more efficient when done right. Therefore we recommend to work in pairs.
• Start from latest version of the develop branch with all the bots we integrated there the last time
• Create your own feature branch to work on! Give it a unique name.
• Follow the instructions in the exercise sheets carefully, there are some hints
• Ask the teachers if you need help

Getting Ready

• Go to the exercise directory where you cloned the repository
• pick a cool feature branch name, something like: feature/bonnie-and-clydes-release-automation
• Run the following commands:

   git checkout develop
   git pull
   git checkout -b feature/<your-feature-branch-name>
   ./gradlew build
  

• You should see BUILD SUCCESSFUL when done
• Go to IntelliJ
• Refresh the project by choosing Synchronize on the project folder (in left hand side project tree)
• Run gradle refresh of your gradle project from right hand side gradle tab (project-automation/Refresh gradle project)
