Troubleshooting Datahub Installation Errors with Separate Backend Configuration

Original Slack Thread


I've been trying to install Datahub for some time now and I'm having a small problem:

I have a separate VM for elasticsearch, mysql, kafka...

I didn't run the prerequisites via helm because I already have the backend ready.

My elasticsearch has the user myuser with the password mypassword.

When running the official datahub Helm pointing to my separate backend, I already see errors first in elasticsearch.

1 - Trying HTTPS:
Problem with request: Get "<https://10.7.1.206:9200>": tls: failed to verify certificate: x509: certificate is valid for 127.0.0.1, not 10.7.1.206. Sleeping 1s

I understand that the Elastic certificate is self-signed and therefore external HTTPS will not be accepted.

2 - Trying HTTP:
Problem with request: Get "<http://10.7.1.206:9200>": EOF. Sleeping 1s

I have some doubts to try to get out of this:

1 - Is there any variable or parameter that I can add or change in values.yaml to add the Elasticsearch username and password?

2 - Is there anything I can do to make Elastic allow the Datahub connection?

I wouldn't want to nest database, elasticsearch, datahub, kafka, everything in the cluster. I need the backend to be separate.

Thanks a lot for the help.```
