node-resource-manager automates compute and storage resource management on nodes in ACK edge Kubernetes clusters. It uses Logical Volume Manager (LVM) to provision storage automatically: it reads the spec configuration you define, creates volume groups (VGs) and persistent volumes (PVs), and makes them available to persistent volume claims (PVCs), so you don't manage local disk topology manually.
How it works
node-resource-manager watches the node-level spec configuration and automatically:
-
Creates LVM volume groups from the local disks on each node
-
Provisions PVs and makes them available for PVCs
Prerequisites
Before using node-resource-manager, confirm the following:
-
You have defined the local disk topology in the node
specconfiguration
Use LVM to manage local storage
For step-by-step instructions on defining disk topology, creating storage classes, and binding PVCs to workloads, see Use LVM to manage local storage.
