You need to edit 'elasticsearch.go' with the following the build the docker image.

	cfg := elasticsearch.Config{
		Addresses:             endpoints,
		DiscoverNodesOnStart:  true,
		DiscoverNodesInterval: 300 * time.Second,
		Transport: &http.Transport{
			MaxIdleConnsPerHost:   2,
			ResponseHeaderTimeout: 30 * time.Second,
			TLSClientConfig: &tls.Config{
				InsecureSkipVerify: true,
			  },
		},
	}
