Adding Nodes to a Node Group

Function

Adds nodes to a node group. During this process, the system checks whether the remaining resources of the current node are sufficient for running all containerized applications deployed in the target node group. If the remaining resources do not meet the requirements, nodes fail to be added to the node group.

MindEdge Framework checks the CPU, memory, and NPU resources of nodes based on the requirements of containerized applications. You need to ensure that other types of container resources are sufficient.

The resource restrictions of MindEdge Framework take effect only on nodes in the ready state.
