Securing Dremio UI

Enabling HTTPS on Dremio’s web server

Add the following parameter to dremio.conf on your coordinator nodes:

services.coordinator.web.ssl.enabled: true

This will automatically generate a self-signed certificated. Go to https://<DREMIO_COORDINATOR>:9047.


Using a self-signed certificate in production is not recommended for security reasons. Most browsers will also warn users when loading the UI in this mode.

Custom SSL keyStore and trustStore settings

Custom SSL keyStore and trustStore can be set using dremio.conf file. If the following are set Dremio will not auto-generate a self-signed certificate.

services.coordinator.web.ssl.keyStore: "path/to/keystore/jks/file",
services.coordinator.web.ssl.keyStorePassword: "keystorePassword",
services.coordinator.web.ssl.trustStore: "path/to/trustStore", (Optional)
services.coordinator.web.ssl.trustStorePassword: "trustStorePassword" (Optional)
