KubeCon + CloudNative North America 2022

Feature flags have long been loved for the ease of turning on or off components running in production. They are fantastic for everything from chaos testing to market research. Open Feature, a new project in the CNCF sandbox, is dedicated to creating a ubiquitous specification for feature flags and enabling them across the entire cloud-native stack. In this talk, we look specifically at the Kubernetes native implementation of Open Feature and illustrate how multiple types of pod workloads can now leverage feature flags. Whether they are web servers, C processes or serverless functions, all can use either Kubeneters native primitives or remote configuration to enable experimentation in a new way. The speaker will walk through key project components such as FlagD and explain the design choices and usage of these services, including an overview of how this enables a complete feature flagging system; with further anecdotes of how multiple communities have collaborated on this project. This first-hand information from one of the project team maintainers will aim to excite and get people thinking about how they can implement feature flags in their own workloads.
