Connect to Elasticsearch:

ElasticConnect.es = Elasticsearch([
                {'host': 'python_elasticsearch', 'port': 9200, 'scheme': 'http'}
            ]);

Create Index:
ElasticConnect.es.indices.create(index=index_name, body=mapping)

Please help me.
What is wrong here.

May be try:

ElasticConnect.es = Elasticsearch([
                {'host': 'localhost', 'port': 9200, 'scheme': 'https'}
            ]);
