I. Git Workflows

• Optimizing your own Git workflow
  • git hooks
  • commit in advance
  • What are the options? Style guides, linting, prettier, whitespace, code analysis…
• Git workflows in the team
  • SVN/CVS workflow: The core "un-workflow" to illustrate the problem
  • github workflow (also called feature branch workflow)
  • What is the best way to use Pull Request/Merge Request?
  • Code review using the web interface
  • Who is doing the merge?
  • What to do if the pull request has premature and sudden conflicts?
  • When and why to use git rebase?
  • Repository management with the web interface – permissions, default branches etc.
  • gitflow workflow
  • Develop your own workflows – that's why it matters? Which model fits best when?
  • tags and releases
• project organization
  • Monorepo vs. Multirepo – the crucial question
  • What are the advantages and disadvantages of both solutions?
  • How do I decide which one suits me best?

2.  CI/CD & GitOps

We'll develop a minimalistic web application to illustrate the concepts.

• continuous integration
  • Introduction to Gitlab CI and the gitlab.yml file
  • Docker Basics: Images and Containers
  • Building a Docker image
  • Local development with Docker
  • Use Gitlab CI to build the Docker image
  • Gitlab runner
  • Leverage Gitlab's Docker Registry
  • Extending the CI pipeline using unit tests as an example
  • Daily/nightly builds
  • Expanding the CI pipelineusing test coverage reports as an example
• continuous deployment
  • Create release and tagged images
  • Install your own private Gitlab runners
  • Automatic deployment using private runners
  • Manual deployment at the push of a button (e.g. for staging or production)
  • Deployment options
  • Manage environment variables and passwords/keys/secrets
• Infrastructure As Code
  • What is "IAC"?
  • What does GitOps mean? (Spoilers: there is no clear definition, the term encompasses a multitude of aspects)
  • Which aspects are these, how do I use them?
  • The merge request as the linchpin
  • Outlook: cloud deployment with Kubernetes
