Node Pools

Create Node Pool for GCE in the DuploCloud Portal

GCP Node Pools are useful when you need to schedule Pods requiring more resources than others, such as more memory or local disk space. Node Pools can be created for the DuploCloud Infrastructure with GKE Standard Cluster only.


Add a Tenant, specifying the DuploCloud Plan corresponding to a GKE Standard Cluster.

Adding a Node Pool

  1. In the DuploCloud Portal, navigate to Kubernetes -> Nodes.

  2. Click the Node Pool tab.

  3. Click Add. The Add Node Pools page displays.

  4. Provide Name, Availability Zone, Instance Type, and Node Counts.

  5. Click Submit.

Adding a Node Pool with Advanced Options

DuploCloud Portal provides additional options when configuring a Node Pool, as depicted below. To use Advanced Options select Advanced Options in the Add Node Pool page.

Adding a Node Pool with Accelerator Type

You can add Accelerator types for GPUs while creating a NodePool. From the Add Node Pool page, click Add Accelerator.

Accelerator Types are not available in all regions.
