Overview

Resizing a VM allows you to change its CPU and RAM allocation. This is useful when your workload requirements change and you need more or fewer resources.

​
Prerequisites

  • The VM must be stopped before resizing
  • An API key and project ID
export RAFF_API_KEY="YOUR_API_KEY"
export RAFF_PROJECT_ID="YOUR_PROJECT_ID"

​
Step 1: Stop the VM

Resizing requires the VM to be in passive (stopped) state: 
curl -X POST -H "X-API-Key: $RAFF_API_KEY" -H "X-Project-ID: $RAFF_PROJECT_ID" \
  https://api.rafftechnologies.com/api/v1/vms/{vm-id}/stop

​
Step 2: Resize the VM

Change the CPU and RAM allocation: 
curl -X POST https://api.rafftechnologies.com/api/v1/vms/{vm-id}/resize \
  -H "X-API-Key: $RAFF_API_KEY" \
  -H "X-Project-ID: $RAFF_PROJECT_ID" \
  -H "Content-Type: application/json" \
  -d '{"cpu": 4, "ram": 8}'
FieldTypeDescription
cpuintegerNew vCPU count
ramintegerNew RAM in GB
Resizing changes your hourly billing rate. The new rate takes effect immediately after the resize completes.

​
Step 3: Start the VM

Start the VM with its new resources: 
curl -X POST -H "X-API-Key: $RAFF_API_KEY" -H "X-Project-ID: $RAFF_PROJECT_ID" \
  https://api.rafftechnologies.com/api/v1/vms/{vm-id}/start

​
Important Notes

  • Storage cannot be reduced — you can only increase storage, not decrease it
  • IP address is preserved — resizing does not change your VM’s public or private IP
  • Data is preserved — all data on the VM is retained during resize
  • Billing changes immediately — the new price_per_hour applies as soon as the resize completes
