External Cache Configuration

This guide demonstrates how to configure an external key-value cache (such as Redis or Memcached) with the Immuta Enterprise Helm chart (IEHC).

Kubernetes namespace

The following section(s) presume the IEHC was deployed into namespace immuta and that the current namespace is immuta.

Prerequisite

The Immuta in production guide must be completed before proceeding.

Redis

Edit secret immuta-secret that was created in the Immuta in production guide.
```
kubectl edit secret/immuta-secret
```
Add key-value IMMUTA_SERVER_CACHE_PROVIDER_OPTIONS_PASSWORD=<cache-password>.

Edit Helm values

Edit the immuta-values.yaml file to include the relevant Helm values listed below. Update all placeholder values with your own values.

Redis

TLS configuration

TLS must be configured both client-side and server-side. The following Helm values demonstrate connecting to Redis with TLS enabled.

cache:
  enabled: false

secure:
  extraConfig:
    server:
      cache:
        provider:
          constructor: catbox-redis
          options:
            host: <redis-fqdn>
            port: <port>
            # Setting options.tls to an empty dict enables TLS without configuring any other options.
            tls: {}

            # Dict representation of TLS config options json-object for package ioredis
            # https://github.com/redis/ioredis
            #
            # tls:
            #   ca:
            #   key:
            #   cert:

  extraEnvVars:
  - name: IMMUTA_SERVER_CACHE_PROVIDER_OPTIONS_PASSWORD
    valueFrom:
      secretKeyRef:
        key: IMMUTA_SERVER_CACHE_PROVIDER_OPTIONS_PASSWORD
        name: immuta-secret

Memcached

cache:
  enabled: false

secure:
  extraConfig:
    server:
      cache:
        provider:
          constructor: catbox-memcached
          options:
            host: <memcached-fqdn>
            port: <port>

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 2024.2.10
