SSL Enablement on the Controller UI

To generate the pinot-keystore.p12 and pinot-truststore.p12 files for securing the Pinot Controller UI using SSL/TLS, follow these steps:

Prerequisites

• Java installed (keytool comes with JDK)
• OpenSSL (optional for importing existing certs)
• Directory /etc/pinot/ssl/ exists and has proper permissions

Generate Keystore and Truststore for Pinot Controller

1. Generate a Keystore (Self-Signed Certificate)

sudo mkdir -p /etc/pinot/ssl

​

keytool -genkeypair \

  -alias pinot-controller \

  -keyalg RSA \

  -keysize 2048 \

  -validity 365 \

  -keystore /etc/pinot/ssl/pinot-keystore.p12 \

  -storetype PKCS12 \

  -storepass changeit \

  -keypass changeit \

  -dname "CN=pinot-controller, OU=Data Platform, O=YourOrg, L=YourCity, ST=YourState, C=US"

• storepass and keypass can be the same.
• Replace CN and other DNAME values as needed.

2. Create the Truststore

If you're using self-signed certs, export the public certificate from the keystore and import it into the truststore.

Export certificate from keystore:

keytool -exportcert \

  -alias pinot-controller \

  -keystore /etc/pinot/ssl/pinot-keystore.p12 \

  -storetype PKCS12 \

  -storepass changeit \

  -file /etc/pinot/ssl/pinot-controller.crt

Import into a new truststore

keytool -importcert \

  -alias pinot-controller \

  -file /etc/pinot/ssl/pinot-controller.crt \

  -keystore /etc/pinot/ssl/pinot-truststore.p12 \

  -storetype PKCS12 \

  -storepass changeit \

  -noprompt

3. Secure Permissions (Optional, but Recommended).

sudo chmod 640 /etc/pinot/ssl/*.p12

sudo chown pinot:pinot /etc/pinot/ssl/*.p12

4. Configure Pinot to use the SSL Certificate.

Edit controller.conf or wherever your Pinot Controller properties are set:

controller.https.port=8443

controller.ssl.keyStore.path=/etc/pinot/ssl/pinot-keystore.p12

controller.ssl.keyStore.password=changeit

controller.ssl.trustStore.path=/etc/pinot/ssl/pinot-truststore.p12

controller.ssl.trustStore.password=changeit

controller.ssl.protocol=TLS

controller.ssl.enabled=true

Restart the Pinot Controller after updating the configuration.

Save and restart the service.
