Embark on a journey exploring Keptn with the maintainers. This user guide presents Keptn's philosophy, features, and its latest innovations, showcasing how it empowers your organization to enforce good DevOps/SRE practices. We will show a unified way to collect DORA metrics out of the box, add tests or security checks, and validate Service Level Objectives (SLO) as part of the deployment, all done in a cloud-native way. Finally, we will demonstrate how Keptn automates and controls the promotion of artifacts across stages while providing and linking traces of your deployments. Keptn leverages OpenTelemetry, Grafana, and existing Kubernetes primitives such as Custom Resources to support an observable delivery of your applications. Join the Keptn community to contribute and shape the project's future.
