How to Configure Network Settings for Vultr Load Balancer

Non‑Public VPC can be selected at creation time and, for Global Load Balancers, per region after creation.

Create time

1. Navigate to Products and click Load Balancers.
2. Click Create Load Balancer.
3. In Load Balancer Configuration, click Non‑Public VPC Network and select your VPC.
4. Complete the remaining settings and click Create Load Balancer.

Per‑region (Global Load Balancer)

1. Open the parent Load Balancer.
2. In the Location table, use the Network column on a region row to select the VPC for that child Load Balancer, then save.

1. Send a GET request to the List Load Balancers endpoint to find your Load Balancer ID.

   console Copy

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

   Explain Code

2. Identify the target Load Balancer and VPC ID from the response.

3. Send a PATCH request to the Update Load Balancer endpoint to assign a VPC network.

   console Copy

   curl "https://api.vultr.com/v2/load-balancers/{load-balancer-id}" \
       -X PATCH \
       -H "Authorization: Bearer ${VULTR_API_KEY}" \
       -H "Content-Type: application/json" \
       --data '{
           "vpc": "vpc-id-goes-here"
       }'
   

   Explain Code

1. List all available Load Balancers and note the ID of your target Load Balancer.

   console Copy

   vultr-cli load-balancer list
   

   Explain Code

2. Update the Load Balancer to assign it to a VPC.

   console Copy

   vultr-cli load-balancer update <load-balancer-id> --vpc <vpc-id>
   

   Explain Code

1. Open your Terraform configuration file for the existing Load Balancer and VPC.

2. Add the vpc_id field to associate the Load Balancer with your target VPC.

   terraform Copy

   resource "vultr_vpc" "private_net" {
       region      = "ewr"
       description = "private-network"
   }
   
   resource "vultr_load_balancer" "lb" {
       region              = "ewr"
       label               = "vultr-load-balancer"
       balancing_algorithm = "roundrobin"
       vpc                 = vultr_vpc.private_net.id
   }
   

   Explain Code

3. Apply the configuration and observe the following output:
