kedacore/keda

KEDA is a Kubernetes-based event-driven autoscaling component written in Go that enables fine-grained autoscaling of containerized workloads based on external events. KEDA operates as a Kubernetes Metrics Server and uses custom resource definitions to define autoscaling rules, making it suitable for both cloud and edge deployments. The project is a Cloud Native Computing Foundation graduated project, indicating its maturity and production readiness within the cloud-native ecosystem.

The repository supports a wide range of event sources and scalers, including AWS SQS, Azure Blob Storage, RabbitMQ, Kafka, and Azure Storage Queues, among others. This extensibility allows users to trigger autoscaling based on virtually any external event source relevant to their workloads. The project provides multiple deployment options including Helm charts, Operator Hub, and direct YAML file deployment, making it accessible to different Kubernetes environments and deployment preferences.

Community engagement around KEDA is substantial and well-organized. The project maintains active communication channels through the Kubernetes Slack workspace in the dedicated KEDA channel and hosts regular community meetings.

The codebase demonstrates quality standards through continuous integration with main build and nightly end-to-end testing workflows. The project maintains security and best practices certifications, including FOSSA compliance tracking and OpenSSF scorecard ratings. Documentation is comprehensive, with resources available at keda.sh covering deployment, configuration, and usage patterns. The project includes multiple quickstart samples demonstrating integration with different event sources and platforms, such as RabbitMQ with Go, Azure Functions with Queues, and Kafka on OpenShift.

KEDA's governance structure is documented separately in a dedicated governance repository, and the project maintains a clear roadmap using GitHub issues for backlog management. The project actively seeks production users and maintains a list of adopters on its website. Contributing guidelines and local build instructions are provided in the repository, along with detailed testing strategy documentation, facilitating community contributions and local development workflows.
