I'm trying to have Pulumi update my Google Domains DNS record after provisioning a static IP address. I got the request working, but I'm seeing that it runs both on the preview and when actually running

pulumi up

. Is there a reason for this and how would I make sure that the record is not updated during the preview?

const googleDomainUrl = pulumi.interpolate `<https://domains.google.com/nic/update?hostname=${mydomain}&myip=${ip.address}>`;
const options =
        {
            method: 'POST',
            headers: {
                'User-Agent': 'Pulumi',
                'Authorization': `Basic ${Buffer.from(`${googleDomainUser}:${googleDomainPass}`).toString('base64')}`
            }
        }



let response = googleDomainUrl.apply(url => fetch(url, options))
