The 7 Deadly Sins of GitOps

GitOps promises simplicity, consistency, and automation, but without discipline, it can just as easily invite drift, outages, and operational pain. GitOps is not a "set it and forget it" solution; it's a living, breathing system that requires ongoing maintenance and nurturing over time.

In this talk, you will learn about the pitfalls of not caring about best practices in GitOps through real-world examples and lessons learned. Whether you're new to GitOps or scaling an enterprise platform, this talk will help you spot warning signs early, avoid painful mistakes, and strengthen your GitOps practices with confidence.


We will cover sins such as pride (ignoring drift), envy (Blindly copying other GitOps setups), sloth (ignoring reconciliation errors), and others, as well as practical fixes and patterns that teams can apply to build more resilient and sustainable workflows.
