Configuration

You shouldn’t need to configure the cache manually, as it’s configured automatically when the cluster is deployed. However, if you need to change the configuration, you can do it by editing the redis section of the Helm chart values file.

You can consult the Bitnami Redis chart for more information about the available configuration options.
