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
-
Create node-resource-topo ConfigMap in kube-system namespace. ConfigMap example is in configmap.md.
kubectl apply -f deploy/configmap.yaml -
Deploy node-resource-manager DaemonSet.
kubectl apply -f deploy/nrm.yamlDeveloper guide
