Database deployments are often the bottleneck in CI/CD pipelines—especially when zero downtime is required. With CloudNativePG and Kubernetes Operators, you can implement an elegant Blue/Green deployment strategy for PostgreSQL that minimizes downtime and simplifies rollbacks. In this talk, I’ll show how to implement this approach, what pitfalls to avoid, and how to integrate it into existing pipelines. A live demo will demonstrate what zero-downtime releases and fast rollbacks look like in practice.
