This talk will go over the hard obstacles we face when going through breaking API changes in ESO API. What are the available CRD versioning patterns? What are the tradeoffs we had to take? What are important aspects to consider when designing CRD versioning?

Kubernetes Operators are becoming the de facto way to create applications that need to interact with a Kubernetes Cluster. When it comes to the lifecycle of this operator, inevitably a breaking change in the API version for the CRDs will happen. Attendees will get an overview on how to design, test and deliver long-term maintainable operators.

External Secrets Operator is a community endeavor that emerged from different open source projects that all tried to solve one problem: pull secrets from a secret management API into Kubernetes. We joined our efforts in 2020 to find a common denominator across projects to build the best solution to that problem and even go beyond that.
Today, we've built a vendor-neutral community around the project and provide a consistent custom resource API across different cloud vendors and secret management APIs.
