How to Attach VPC Networks on a Vultr Cloud GPU Instance

Updated on November 27, 2024

A Virtual Private Cloud (VPC) network enables a secure and isolated private networking interface on your instance for communication with other instances in the same network. You can attach multiple VPC networks to enable communication between an instance and other nodes attached to the same network.

Follow this guide to attach VPC networks on a Vultr Cloud GPU instance using the Vultr Customer Portal, API, or CLI.

    Attach a VPC to an Instance

  1. Send a GET request to the List Instances endpoint and note the target instance's ID in your output.

    console 
    $ curl "https://api.vultr.com/v2/instances" \
  -X GET \
  -H "Authorization: Bearer ${VULTR_API_KEY}"

  2. Send a GET request to the List VPCs endpoint to list all VPCs in your Vultr account and note the target VPC network's ID.

    console 
    $ curl "https://api.vultr.com/v2/vpcs" \
  -X GET \
  -H "Authorization: Bearer ${VULTR_API_KEY}"

  3. Send a POST request to the Attach VPC to Instance endpoint to attach the VPC network to the instance.

    console 
    $ curl "https://api.vultr.com/v2/instances/{instance-id}/vpcs/attach" \
  -X POST \
  -H "Authorization: Bearer ${VULTR_API_KEY}" \
  -H "Content-Type: application/json" \
  --data '{
    "vpc_id": "<vpc-id>"
  }'

  1. List all instances in your Vultr account and note the target instance's ID.

    console 
    $ vultr-cli instance list

  2. List all VPC networks in your Vultr account and note the target VPC network's ID.

    console 
    $ vultr-cli vpc list

  3. Attach the VPC network to the instance.

    console 
    $ vultr-cli instance vpc attach <instance-id> --vpc-id="<vpc-id>"
