Version: v1.4

Install Lower-Layer System

Introduction​

The lower-layer system provides the Kubernetes/KubeEdge cluster, Sedna runtime management, and EdgeMesh service communication required by Dayu. Install it on the cloud-edge cluster before starting Dayu's support services.

For the role of each component, see the architecture overview.

Companion components​

The current system uses dayu-sedna v1.1 and dayu-edgemesh v1.1. Both components must use the same minor version; do not mix minor versions.

Installation order​

  1. Prepare the nodes.
  2. Install Kubernetes on the cloud node.
  3. Install KubeEdge and join the edge nodes.
  4. Install EdgeMesh.
  5. Install Sedna.
  6. Optionally install NVIDIA GPU support.

Before continuing​

  • Confirm every required node is Ready and node clocks are synchronized.
  • Confirm Sedna GM can communicate with every LC.
  • Confirm EdgeMesh agents are healthy on the cloud and edge nodes.
  • Confirm endpoint-bearing RuntimeServices can reach Activated=True and Ready=True; a running Pod alone is not sufficient for Dayu.
  • Check FAQs for known cluster, DNS, GPU, and routing issues.
