Is Platform Engineering the new DevOps? Why do you need a platform? Why building a platform is so hard? In this talk we will cover the usual pitfalls when building a platform, patterns and anti-patterns. What works, what should work but does not and what can we do to minimise the many bumps on the road. We will see how Docker helps to build and run a platform. How do we use Docker at Docker to build a Platform and how it could help eve more... but fear not, this is not a sales pitch. This talk is a lessons learned while building platforms. There will be YAML, failed tests, broken infra and misconfigured GitOps. Also, the presentation might contain a fair amount of GIFs.
