Google Cloud - Sole-tenant Nodes

Step-01: Introduction

  • Explore about creating sole-tenant nodes using google cloud console

Step-02: Create a Sole-tenant Node

  • Go to Compute Engine -> Virtual machines -> Sole-tenant Nodes -> CREATE NODE GROUP

Node group properties

  • Name: node-group-1
  • Region: us-central1
  • Zone: us-central1-a
  • Click on CONTINUE

Node template properties

  • Click on CREATE NODE TEMPLATE
  • Name: node-template-1
  • Node type: c2-node-60-240
  • Local SSD: none
  • GPU accelerator: none
  • Affinitly Lables
  • Key: appname
  • Value: mybankingapps
  • Click on CREATE
  • Click on CONTINUE

Configure autoscaling

  • Autoscaling mode: on
  • Minimum Number of nodes: 1
  • Maximum Number of nodes: 3
  • Click on CONTINUE

Configure maintenance settings (optional)

  • Maintenance policy: Default (RECOMMENDED)
  • Maintenance window: 0:00 - 4:00
  • Click on CONTINUE

Configure share settings (optional)

  • Select Do not share this node group with other projects
  • Click on CREATE DONT CREATE IT - WE ARE JUST EXPLORING

Step-03: Delete the Node Template

  • Go to Compute Engine -> Virtual machines -> Sole-tenant Nodes -> Node Templates
  • Delete node-template-1
