Constraints

Before deploying Kunpeng TAP, ensure that the server, Kubernetes, and Docker (or containerd) versions meet the requirements described in this document to fully utilize this plugin. Theoretically, the plugin can also run properly in later versions.

For servers with Kunpeng 920 series processors, Kunpeng TAP supports NUMA affinity optimization for Kubernetes clusters. Table 1 lists the verified software versions.

• Kunpeng TAP depends on the Kubernetes cluster and a container runtime (Docker or containerd). In the Docker scenario, use Dockershim as the communication component. Before deployment, ensure that the network configuration of the Kubernetes cluster is correct and container instances can be deployed and run properly.
• Kunpeng TAP is incompatible with the open source Kubernetes topology manager. Before deploying the plugin, ensure that the open source Kubernetes topology manager is disabled (disabled by default). You can check that --topology-manager-policy is disabled in the kubelet command line.
