How to Manage Trusted Sources for Vultr Managed Databases for MySQL

Updated on 27 August, 2025

Trusted sources allow you to restrict access to your managed databases by specifying the list of IP addresses that can securely connect to the database instance. This security mechanism reduces the risk of unauthorized access by preventing DDoS and brute-force attacks. Trusted sources work on top of other security measures like user access control.

Follow this guide to manage trusted sources for Vultr Managed Databases for MySQL using the Vultr Customer Portal, API, CLI, or Terraform.

  • Vultr Customer Portal
  • Vultr API
  • Vultr CLI
  • Terraform
  1. Navigate to Products and select Databases.
  2. Click the target database instance.
  3. Navigate to Trusted Sources under Overview and click Edit.
  4. Specify a list of the IP addresses of the servers that you want to allow to connect to the database and click Save.

  1. List all the database instances by sending a GET request to the List Managed Databases endpoint and note the database ID. For example, 43b4c774-5dff-4ac0-a01f-78a23c2205b5.

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

  2. Send a PUT request to the Update Managed Database endpoint to add the IP addresses of the servers that you want to allow to connect to the database in array format and specify the database ID.

    console 
    $ curl "https://api.vultr.com/v2/databases/database_id" \
    -X PUT \
    -H "Authorization: Bearer ${VULTR_API_KEY}" \
    -H "Content-Type: application/json" \
    --data '{
        "trusted_ips" : ["192.0.2.1","192.0.2.2","192.0.2.3"]        
    }'

    Visit the Update Managed Database endpoint to view additional attributes to add to your request.

  1. List all database instances and note the database ID. For instance, d6ac2a3c-92ea-43ef-8185-71a23e58ad8c.

    console 
    $ vultr-cli database list --summarize

  2. Add the IP addresses of the servers that you want to allow to connect to the database (For instance, 192.0.2.1,192.0.2.2,192.0.2.3) and specify the database ID.

    console 
    $ vultr-cli database update database_id \
--trusted-ips "192.0.2.1,192.0.2.2,192.0.2.3"

    Run vultr-cli database update --help to view all options.

  1. Open your Terraform configuration for the existing Managed Database for MySQL resource.

  2. Add or update the trusted_ips argument with the approved source IP addresses.

    terraform 
    resource "vultr_database" "mysql" {
    # ...existing fields (database_engine, region, plan, label, etc.)

    trusted_ips = [
        "192.0.2.1",
        "192.0.2.2",
        "192.0.2.3"
    ]
}

  3. Apply the configuration and observe the following output:

    Apply complete! Resources: 0 added, 1 changed, 0 destroyed.
