1. PRODUCTIVITY BOOSTED BY DEVOPS BUILD CHAIN OPTIMIZATION IN A SERIOUS GAME KAI-DOMINIK KUHN Saarbrücken · 13.11.2018
2. Kai-Dominik Kuhn Master of Science Computer Science Design Engineer at Centigrade (SB) since 2017
3. DevOps: Why – How – Benefits Context: Intro to the Game Continuous Pipeline Lessons Learned AGENDA
4. WHY – WHAT WILL IT HELP US WITH We want to … • understand what users really need / love • build something that brings value to the end users • get early feedback on what we do • deliver qualitative good code • deliver stable and bug free software • do the right things right • AND we want do all of this fast and efficient
5. HOW – WILL WE ACHIEVE THAT • Version control system git • Checking code quality linting • Testing unit tests, integration tests • Code reviews branching -> merge requests • Automate GitLab Runner, Jenkins, CircleCI, … • Continuously deploy CD • Deploy microservices Docker, Kubernetes
6. WHAT – ARE OUR BENEFITS • Bring continuity to software development • Bring continuity even into the user-centered processes – from user research till user feedback • Get qualitative good code and reliable solutions • Enabling developers to deploy to the customer with a simple merge • Benefit from faster cycles as well as early and valuable user feedback. https://cdn-images-1.medium.com/max/1600/1*AwvDJDfErlD34ox2QpwGoA.png

33. HOW DID IT HELP • Continuous Pipeline • get early feedback on what we do • do the right things right • build something that brings value to the end users • understand what users really need / love • Continuous review, run tests & linting • deliver qualitative good code • deliver stable and bug free software • do the right things right • GitLab + GitLab Runner (not Walker) • do all of this fast and efficient
34. LESSONS LEARNED • Get early access to the testing / staging / productive environment for every participating colleague • Test regularly in the customer’s environment • Negotiate the environment at the kick off meeting and make clear that later changes to that decision might be expensive • Throughout the project, choose a standard process for the internationalization that the customer must adhere to when delivering the languages • Standard Angular i18n approach, means one build per language (ngx-translate) • AzureAD for WebApps is not a solution, it is a pain! (Bad cookie management) • Enterprise SSO together with AzureAD for WebApps can / will lead to difficulties • Build Unity application in a docker is difficult and slow
