Example

river 
discovery.lightsail "lightsail" {
  region = "us-east-1"
}

prometheus.scrape "demo" {
  targets    = discovery.lightsail.lightsail.targets
  forward_to = [prometheus.remote_write.demo.receiver]
}

prometheus.remote_write "demo" {
  endpoint {
    url = PROMETHEUS_REMOTE_WRITE_URL

    basic_auth {
      username = USERNAME
