Hello Elastic, I found this github to run my own sample apps for a starting point for my project [Elastic LangChain Sample App](https://github.com/elastic/elasticsearch-labs/blob/main/example-apps/workplace-search/README.md) I would like to run this apps but I notice it requires Elastic Could ID? Currently I've been using the Self-managed platform, how do I define the environment? ![Screenshot 2023-11-15 at 9.03.33 AM](https://us1.discourse-cdn.com/elastic/original/3X/6/6/66cdb3b8ebdefa23d735e272bee73b2bc572adc2.png) I'm interested to run this notebook also : [Question-Answering](https://github.com/elastic/elasticsearch-labs/blob/main/notebooks/generative-ai/question-answering.ipynb), and I notice I need to use the Elastic Cloud ID also. ![Screenshot 2023-11-15 at 9.08.03 AM](https://us1.discourse-cdn.com/elastic/original/3X/f/8/f89d626f42f72f18477a2d1666e8e8cbcfa855e7.png) Couldn't we define the Hostname of the Elastic or we really need to use the Cloud Id for this notebook? Thank you. ---

Hi @aisyaharifin , the notebooks use cloud because it's very easy to spin up. You could use these examples and the [ElasticsearchStore documentation](https://api.python.langchain.com/en/latest/vectorstores/langchain.vectorstores.elasticsearch.ElasticsearchStore.html) to modify cloud examples to work with an on prem deployment. ---

as @Kathleen_DeRusso mentioned, you can adjust the connection details using the documentation. This is a better documenation link which shows all the connection options available. [https://python.langchain.com/docs/integrations/vectorstores/elasticsearch#authentication](https://python.langchain.com/docs/integrations/vectorstores/elasticsearch#authentication) In the case of using the url, you can use ```auto ElasticsearchStore( es_url="URL", es_user=CLOUD_USERNAME, es_password=CLOUD_PASSWORD, ``` For the app, you can update the code to connect to url here [https://github.com/elastic/elasticsearch-labs/blob/main/example-apps/workplace-search/api/elasticsearch\_client.py#L10-L12](https://github.com/elastic/elasticsearch-labs/blob/main/example-apps/workplace-search/api/elasticsearch_client.py#L10-L12) We will in future support es\_url via env variable soon. ---

Thank you for the reply. So I've countered this error on the ssl when I run the script, is there a way we could disable the ssl verification? `Error connecting to Elasticsearch: TLS error caused by: TlsError(TLS error caused by: SSLError([SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1129)))` Thanks. ---

You can create connection and pass it like this ```py conn = Elasticsearch( "https://localhost:9200", ca_certs = "/tmp/ca.crt", basic_auth = ("username", "password") ) es = ElasticsearchStore( es_connection=conn, index_name="test", embedding=embeddings ) ``` ---

What Ashish is showing in this example is providing the self-signed SSL cert to the elasticsearch client. If your self-hosted elasticsearch is only for development purposes, you can disable SSL. Heres an example of how to run via docker here [Elasticsearch | 🦜️🔗 Langchain](https://python.langchain.com/docs/integrations/vectorstores/elasticsearch#running-elasticsearch-via-docker) ---
