When you create a Kubernetes cluster in Google Distributed Cloud (GDC) air-gapped, you create node pools that are responsible for running your container workloads in the cluster. You provision nodes based on your container workload requirements, and can update them as your requirements evolve.
GDC provides predefined machine types for your worker nodes that are selectable when you add a node pool. There are also multiple ways to partition separate GPU instances using the Multi-Instance GPU (MIG) feature.
This document is for application developers within the application operator group and IT administrators within the platform administrator group who are responsible for managing Kubernetes clusters within their organization. For more information, see Audiences for GDC air-gapped documentation.
Reference the following sections for available machine types and GPU support.
Available machine types
GDC defines machine types with some parameters
for a Kubernetes cluster node, which include CPU, memory, and GPU.
GDC has various machine types for different purposes.
For example, clusters use n2-standard-4-gdc for general purpose container
workloads. If you plan to run artificial intelligence (AI) and
machine learning (ML) notebooks, you must provision GPU machines, such as
a2-highgpu-1g-gdc.
The following is a list of all GDC predefined machine types available for Kubernetes cluster worker nodes:
| Name | vCPUs | Memory | GPU |

Supported MIG profiles
This section defines the supported partitioning schemes of MIG profiles on
supported GPUs. You can define a partitioning scheme for a node pool in your
Cluster custom resource.
For more information on how to apply a GPU partitioning scheme, see Add a node pool.
