- KEDA Concepts
What is KEDA? KEDA is a tool that helps Kubernetes scale applications based on real-world events It was created by Microsoft and Red Hat With KEDA, you can adjust the size of your containers automatically, depending on the workload—like the number of messages in a queue or incoming requests
- KEDA | Getting Started
Welcome to the documentation for KEDA, the Kubernetes Event-driven Autoscaler Use the navigation bar on the left to learn more about KEDA’s architecture and how to deploy and use KEDA
- Scaling Deployments, StatefulSets Custom Resources - KEDA
With KEDA you can scale any workload defined as any Custom Resource (for example ArgoRollout resource) The scaling behaves the same way as scaling for arbitrary Kubernetes Deployment or StatefulSet
- Deploying KEDA
This command installs KEDA in a dedicated namespace (keda) You can customize the installation by passing additional configuration values with --set, allowing you to adjust parameters like replica counts, scaling metrics, or logging levels
- Scalers - KEDA
KEDA External Scaler that can obtain metrics from OTel collector and use them for autoscaling
- AWS SQS Queue - KEDA
When identityOwner set to operator - the only requirement is that the KEDA operator has the correct IAM permissions on the SQS queue Additional Authentication Parameters are not required
- ScaledObject specification - KEDA
This is the interval to check each trigger on By default, KEDA will check each trigger source on every ScaledObject every 30 seconds When scaling from 0 to 1, the polling interval is controlled by KEDA For example, if this parameter is set to 60, KEDA will poll for a metric value every 60 seconds while the number of replicas is 0
- RabbitMQ Queue - KEDA
timeout - Timeout in milliseconds for this specific trigger This value will override the value defined in KEDA_HTTP_DEFAULT_TIMEOUT (Optional, Only applies to hosts that use the http protocol) excludeUnacknowledged - Set to true to specify that the QueueLength value should exclude unacknowledged messages (Ready messages only)
