Managed Public Cloud

This is a guide on how to deploy Immuta on Kubernetes in the following managed public cloud providers:

  • Amazon Web Services (AWS)

  • Microsoft Azure

  • Google Cloud Platform (GCP)

Prerequisites

The following cloud-managed services must be provisioned before proceeding:

Validation

PostgreSQL

  1. The PostgreSQL instance's hostname/FQDN is resolvable from within the Kubernetes cluster.

  2. The PostgreSQL instance is accepting connections.

  3. The Helm chart only supports username/password authentication for PostgreSQL. At this time, other authentication mechanisms are not supported.

Elasticsearch

  1. The Elasticsearch instance's hostname/FQDN is resolvable from within the Kubernetes cluster.

  2. The Elasticsearch instance is accepting connections.

  3. The user must have the required permissions.

  4. The Helm chart only supports username/password authentication for Elasticsearch. At this time, other authentication mechanisms are not supported.

Authenticate with OCI registry

Helm chart availability

The deprecated Immuta Helm chart (IHC) is not available from ocir.immuta.com.

Copy the snippet below and replace the placeholder text with the credentials provided to you by your customer success manager:

echo <token> | helm registry login --password-stdin --username <username> ocir.immuta.com

Setup

  1. Create a Kubernetes namespace named immuta for Immuta.

    kubectl create namespace immuta

  2. Switch to namespace immuta.

    kubectl config set-context --current --namespace=immuta

  3. Create a container registry pull secret. Your credentials to authenticate with ocir.immuta.com can be viewed in your user profile at support.immuta.com.

    kubectl create secret docker-registry immuta-oci-registry \
    --docker-server=https://ocir.immuta.com \
    --docker-username="<username>" \
    --docker-password="<token>" \
    [email protected]

PostgreSQL

Connecting to the database

There are numerous ways to connect to a PostgreSQL database. This step demonstrates how to connect by creating an ephemeral Kubernetes pod.

  1. Connect to the database as superuser (postgres) by creating an ephemeral container inside the Kubernetes cluster. A shell prompt will not be displayed after executing the kubectl run command outlined below. Wait 5 seconds, and then proceed by entering a password.

    kubectl run pgclient \
    --stdin \
    --tty \
    --rm \
    --image docker.io/bitnami/postgresql -- \
    psql --host <postgres-fqdn> --username <postgres-admin> --dbname postgres --port 5432 --password

  2. Create an immuta role and database.

    CREATE ROLE immuta with login encrypted password '<postgres-password>';

GRANT immuta TO CURRENT_USER;

CREATE DATABASE immuta OWNER immuta;

GRANT all ON DATABASE immuta TO immuta;
ALTER ROLE immuta SET search_path TO bometadata,public;

  3. Revoke privileges from CURRENT_USER as they're no longer required.

    REVOKE immuta FROM CURRENT_USER;

  4. Enable the pgcrypto extension.

    \c immuta
CREATE EXTENSION pgcrypto;

  5. Type \q, and then press Enter to exit.

Install Immuta

Audit records

Preserving legacy audit records

Immuta does not migrate legacy audit records to the universal audit model (UAM), so when you upgrade Immuta those audit records will be lost unless you enable the following setting in your immuta-values.yaml file:

secure:
  extraEnvVars:
    - name: FeatureFlag_auditLegacyViewHide
      value: "false"

Audit record retention

Immuta defaults to keeping audit records for 7 days. To change this duration, set the following values in the immuta-values.yaml file. The example below configures audit records to be kept for 90 days:

audit:
  deployment:
      extraEnvVars:
        - name: AUDIT_RETENTION_POLICY_IN_DAYS
          value: "90"

This section demonstrates how to deploy Immuta using the Immuta Enterprise Helm chart once the prerequisite cloud-managed services are configured.

  1. Create a Helm values file named immuta-values.yaml with the following content:

    global:
  imageRegistry: ocir.immuta.com
  imagePullSecrets:
    - name: immuta-oci-registry
  imageRepositoryMap:
    immuta/immuta-service: stable/immuta-service
    immuta/immuta-db: stable/immuta-db
    immuta/immuta-fingerprint: stable/immuta-fingerprint
    immuta/audit-service: stable/audit-service
    immuta/audit-export-cronjob: stable/audit-export-cronjob
    immuta/classify-service: stable/classify-service
    immuta/cache: stable/cache

audit:
  config:
    databaseConnectionString: postgres://immuta:<postgres-password>@<postgres-fqdn>:5432/immuta?schema=audit
    elasticsearchEndpoint: <elasticsearch-endpoint>
    elasticsearchUsername: <elasticsearch-username>
    elasticsearchPassword: <elasticsearch-password>

secure:
  ingress:
    enabled: false
    tls: false
  extraEnvVars:
    - name: FeatureFlag_AuditService
      value: "true"
    - name: FeatureFlag_detect
      value: "true"
    - name: FeatureFlag_auditLegacyViewHide
      value: "true"

  postgresql:
    host: <postgres-fqdn>
    port: 5432
    database: immuta
    username: immuta
    password: <postgres-password>
    ssl: true

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

  3. Deploy Immuta.

    helm install immuta oci://ocir.immuta.com/stable/immuta-enterprise \
    --values immuta-values.yaml \
    --version 2024.2.20

Validation

  1. Wait for all pods in the namespace to become ready.

    kubectl wait --for=condition=Ready pods --all

  2. Determine the name of the Secure service.

    kubectl get service --selector "app.kubernetes.io/component=secure" --output name

  3. Listen on local port 8080, forwarding TCP traffic to the Secure service's port named http.

    kubectl port-forward service/<name> 8080:http
