AWS S3 Upstream Discovery

Continuously polls a file in S3 that contains a list of Upstream Service Objects. If the file is invalid, the S3UpstreamWatcher treats it as if there was no update.

// Domain Object
{
  upstream-watcher: S3UpstreamWatcher

  s3-upstream-watcher {

    // The bucket name that contains the config file
    bucket-name: "s3-upstreams-bucket-name"

    // The key within the bucket to the config file.
    config-filename: "domains.conf"

    // The duration between polling for file updates
    refresh-interval: 30s
  }
}

  // Upstream Service Objects
