I am trying to configure the MongoDB Connector in Enterprise Search to see if we can pull MongoDB collections into Elasticsearch Indices. I have Elasticsearch 8.6.0, Kibana 8.6.0, Enterprise Search 8.6.0, and MongoDB 6.0.1 setup and running in a Docker swarm. Enterprise Search seems to be working and and I can configure the ES index and setup the MongoDB connector, but when I try to sync it just says "Waiting for a connector to pickup" and the sync just spins.
When I look at Enterprise Search > Content > Indices in Kibana, I have 1 "Incomplete ingest methods". If I delete the index using the Connector ingest method, that goes to 0, so obviously my MongoDB connector is incomplete.
The index shows as "Configured", but not Connected.
Here is the MongoDB configuration in Index setup
I have no problem connecting to MongoDB and reading from this database/collection using the same credentials from another client such as Robo3T or mongoshell.
hey @m.hanna !
Can you please check the Enterprise Search logs to look for potential problems in the connection from the Connector point of view?
Can you try to log in your Enterprise Search docker container and check connectivity to the MongoDB host? Docker networking can be troublesome to set up, and it's possible that Enterprise Search Docker container is not able to access the MongoDB container.
Please share your findings!
Thanks for the response.
I am not sure what log to look in really.

None of which gave me any clue why it might not be connecting to Mongo.
I installed mongo shell (mongosh) in the container and I am able to successfully connect to my MongoDB from the container using the same credentials I configured in the connector.

hey @m.hanna , thanks for checking the connectivity!
I'm afraid that using Docker for running Enterprise Search does not include the native connectors needed to use the MongoDB connector. You will need to:
- Install it separately as part of your deployment. Please check this repository for instructions.
- A Platinum subscription for running it, or a Trial to check it suits your needs.
Alternatively, use Elastic Cloud to have everything configured for you out of the box. Elastic Cloud deployments include native connectors for Enterprise Search deployments of at least 4GB of memory.
Please check this documentation for additional information.
Thanks. That is disappointing.
I thought that might be the case after I posted the first message here. But I ran into some issues trying to add the connectors-python into a new docker image. I guess I will continue to work on it.
@m.hanna you can run the MongoDB connector as a client, rather than native to test it out btw. Run the MongoDB connector (it's in the ruby repo rather than the python one) GitHub - elastic/connectors-ruby: Official Connector Clients for Elastic Elasticsearch, Enterprise Search, App Search and Workplace Search and then run through the "Build a connector" workflow in Kibana to register it. Give it a try, we'd love your feedback. If you'd like to screenshare and point out your feedback on the connectors, let me know in DM and we can set up a feedback session.
Sorry for the late reply, I got a container built with connectors-ruby installed, but the it doesn't connect to elasticsearch. I am getting the following error in the docker logs
/root/.rbenv/versions/2.6.9/lib/ruby/gems/2.6.0/gems/httpclient-2.8.3/lib/httpclient/ssl_socket.rb:103:in `connect': SSL_connect returned=1 errno=0 state=error: certificate verify failed (unable to get local issuer certificate) (OpenSSL::SSL::SSLError)
Obviously a certificate error but I don't see where to define the ca cert for elasticsearch in connectors-ruby/CONFIG.md at main · elastic/connectors-ruby · GitHub. The python connector does have settings for
ca_certs:, however adding those settings to
connectors.yml didn't seem to work for the ruby connector.
Hi @m.hanna, could you please try setting an environment variable
SSL_CERT_FILE=<PATH_TO_YOUR_CERT> and then launching the connector? This will have to be added to the Makefile or a custom bash script if you're using it.
If that works please let me know and I'll follow up with feedback on our documentation.
SSL_CERT_FILE to the environment and adding
ca.crt as a secret in the
docker-compose file worked.
If interested, here is the snippet for the connector:
- source: connectors.yml
- source: ca.crt
Enterprise-search has now successfully synced documents from mongodb to elasticsearch.
Thanks for following up! I'm glad that it worked for you. I'll follow up with the team RE: documenting this.
