openyurtio/node-resource-manager

English | 简体中文

Node-resource-manager manages local node resources of OpenYurt cluster in a unified manner.

It currently manages:

• LVM built on top of block device or pmem device.
• QuotaPath built on top of block device or pmem device.
• Memory built on top of pmem device.

The majority function consists of:

• Initialize local resources on edge node.
• Update local resources on edge node.

You can define the spec of local resources by simply modifying the pre-defined ConfigMap.

Node-resource-manager has the following advantages in terms of compatibility and usability.

• Easily to use. Initialization and modification of local resources are easily done by editing the ConfigMap.
• Easily to integrate. Node-resource-manager can work together with csi driver, to perform local storage lifecycle management.
• Platform free. Node-resource-manager can be running in any kubernetes clusters.

Architecture

The component consists of two parts, the first part is the ConfigMap named node-resource-topo in kube-system namespace, and the second is the node-resource-manager DaemonSet deployed in kube-system namespace. Node-resource-manager on each node mounts and reads the node-resource-topo ConfigMap to managed local resources.

Getting started

1. Create node-resource-topo ConfigMap in kube-system namespace. ConfigMap example is in configmap.md.

   kubectl apply -f deploy/configmap.yaml

2. Deploy node-resource-manager DaemonSet.

kubectl apply -f deploy/nrm.yaml
