Managing Node Groups

What is a Node Group?

A Node Group is a logical collection of Kubernetes nodes that share common hardware characteristics, such as CPU and GPU manufacturer/model. Node groups enable administrators to:

• Target Workloads: Schedule specific applications (e.g., GPU-intensive AI jobs) to nodes with compatible hardware.
• Simplify Management: Apply policies, quotas, or updates to groups of nodes collectively.
• Optimize Costs: Isolate workloads to nodes with cost-effective hardware for their requirements.

Key Features

• Resource Allocation: Reserve nodes for critical workloads or teams.
• Scalability: Dynamically add/remove nodes as demand changes.

Node Group Operations

• Create a Node Group:
  • Create a new node group to organize nodes with shared attributes (e.g., GPU type, memory capacity).
• Delete a Node Group:
  • Remove a node group when it’s no longer needed. This does not delete the nodes themselves.
• Edit a Node Group:
  • Modify group properties, such as adding or removing nodes from the node group, etc.
