Description

I am not able to connect. FYI - I need to use ssl
"sslmode=verify-ca sslrootcert=server-ca.pem sslcert=client-cert.pem sslkey=client-key.pem"

I can login to my psotgres using my credentials and above mentioned certificate through pgadmin client but not through exporter, also exporter does not through any error just info message

Command I run is:
docker run -v C:\mycert:/etc/ssl/certs --net=host -e DATA_SOURCE_NAME="postgresql://postgres:password@xx.xx.xx.xx:5432/postgres?sslmode=require" wrouesnel/postgres_exporter
time="2021-02-17T06:01:03Z" level=info msg="Starting Server: :9187" source="postgres_exporter.go:1825"

Research direction

Start by reproducing the reported Docker command with DATA_SOURCE_NAME and the mounted certificate directory, then compare its SSL parameters with the certificate connection that works in pgAdmin. Check the postgres_exporter startup and connection behavior; done means the exporter connects using the supplied certificates and exposes PostgreSQL metrics or reports a clear connection error.
