Features 10

Notable capabilities this provider offers.

Dynamic Device Discovery

Automatically discovers heterogeneous leaf devices (IP cameras, USB devices, industrial sensors) across Kubernetes cluster nodes using protocol-specific Discovery Handlers.

ONVIF Discovery Handler

Discovers IP cameras via ONVIF standards and RTSP streams, with filtering by IP address, MAC address, ONVIF scopes, and device UUIDs.

OPC UA Discovery Handler

Discovers industrial automation servers and Local Discovery Servers via OPC UA protocol, supporting x509 certificate authentication for secure connections.

udev Discovery Handler

Discovers locally attached hardware (USB devices, cameras, microphones) on Linux nodes using udev rules with kernel device name and capability filtering.

Automatic Workload Scheduling

Automatically schedules broker Pods or Jobs per discovered device based on Akri Configuration specifications, managing the full workload lifecycle.

High Availability

Multiple nodes can access a single leaf device, ensuring service continuity if a node fails. Supports multi-node device reservation.

Kubernetes Custom Resources

Two CRDs: configurations.akri.sh for discovery specification and instances.akri.sh representing each discovered device as a Kubernetes resource.

Extensible Discovery Handler Framework

Community can implement custom Discovery Handlers as DaemonSets using the akri-discovery-handler-template, enabling support for any device protocol.

Prometheus Metrics

Built-in Prometheus metrics on port 8080 for instance count, discovery response results, discovery latency, and broker pod count, with Grafana visualization support.

Multi-Architecture Support

Supports Linux nodes on amd64, arm64v8, and arm32v7 architectures with Kubernetes v1.16+, K3s, and MicroK8s distributions.
