Enabling Legacy Query Engine and Fingerprint

The query engine and fingerprint services are no longer installed by default. This guide demonstrates how to enable the query engine and fingerprint services using the Immuta Enterprise Helm chart (IEHC).

If you are using any of the data platforms below, you must enable the query engine:

• Amazon Redshift

• Azure Synapse Analytics

• Google BigQuery

• Any legacy database

If you are using the legacy sensitive data discovery (SDD) feature, you must enable the query engine and fingerprint services.

Prerequisites

• The Immuta in production guide must be completed before proceeding.

• Validate that secret immuta-secret exists in the current namespace.

  Copy

  kubectl get secret/immuta-secret

Create Kubernetes secret

1. Create a file named secret-data.env with the following content.

   Copy

   # query-engine
   IMMUTA_FEATURE_PASSWORD=<immuta-feature-password>
   PATRONI_SUPERUSER_PASSWORD=<patroni-superuser-password>
   PATRONI_REPLICATION_PASSWORD=<patroni-replication-password>
   PATRONI_RESTAPI_PASSWORD=<patroni-api-password>

2. Create secret named immuta-legacy-secret from file secret-data.env

   Copy

   kubectl create secret generic immuta-legacy-secret --from-env-file=secret-data.env

3. Delete file secret-data.env, as it's no longer needed.

   Copy

   rm -i secret-data.env

Edit Helm values

1. Edit the immuta-values.yaml file to include the following Helm values.

   Copy

   legacy:
     enabled: true
   
     queryEngine:
       statefulset:
         extraEnvVars:

2. Update all placeholder values in the immuta-values.yaml file.

Apply Helm values

Perform a Helm upgrade to apply the changes made to immuta-values.yaml.

helm upgrade <release-name> oci://ocir.immuta.com/stable/immuta-enterprise --values immuta-values.yaml --version 2024.3.5
