# Redis

> Configure Redis Helm values for Live Agent with options for in-cluster or external Redis, managed solutions, and compatible versions between 5 and 7.

<Warning>
  Live Agent has been put in maintenance mode. The product will continue to be maintained in the foreseeable future. Users can continue to fully rely on Live Agent being available. In future releases, only security updates and bug fixes will be provided; no new features will be released.
</Warning>

Redis is an in-memory data structure store used for caching and improving performance across the application.
It can either run inside the Kubernetes cluster as an additional workload, or outside the cluster.
You can also use a fully managed solution for PostgreSQL.

Compatible and tested Redis versions are later than 5 and earlier than 7.

## Redis Variables

| Key                                | Type   | Default                          | Description                                                                                                                           |
| ---------------------------------- | ------ | -------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------- |
| `redis.enabled`                    | Bool   | true                             | Set to `false` if using external redis and modify the below variables.                                                                |
| `redis.host`                       | string | `Internal Redis Deployment Name` | Redis Host Name                                                                                                                       |
| `redis.auth.password`              | string | `"redis"`                        | Redis Password                                                                                                                        |
| `redis.master.persistence.enabled` | bool   | `true`                           | Persistence can be disabled completely, if you want your data to only exist while the server is running.                              |
| `redis.nameOverride`               | string | `"live-agent-redis"`             | Override the deployment name, if internal Redis is enabled.                                                                           |
| `redis.sentinelMasterName`         | string | `""`                             | A Redis sentinel master name is required when using sentinel.                                                                         |
| `redis.sentinels`                  | string | `""`                             | Redis Sentinel can be used by passing a list of sentinel hosts and ports. For example: `sentinel_host1:port1`, `sentinel_host2:port2` |

## Internal Setup

It is a good practice to change the `redis.auth.password` in the `values.yaml` file. To do this, you can change the value, or comment, on the line `password: redis` before installing the Helm chart, which will autogenerate a password.

## External Setup

1. Go to the `values.yaml` file and scroll down to the `redis` field. Change the `enabled` value to `false`.

2. Type the user credentials, and uncomment the properties `host` and `port`, assigning them the correct values.

3. Define a password to access the external Redis instance:
   * A. A secret is created by default. Edit the password inside the Redis secret. The secret name is composed of the `release name` + `redis`.
   * B. (Recommended) Define an existing secret. Create the secret and set the values inside the `values.yaml` file. The keys are `redis.existingSecret` and `redis.existingSecretPasswordKey`.
