# External Redis

By default the helm chart is using bitnami redis, this container is only for testing purposes and for a real cluster it is better to use an external redis.

To enable it, the following values can be used:

```yaml
api:
  defaultRedis: false
  env:
  - name: TerrakubeRedisSSL
    value: "true"
  - name: TerrakubeRedisTruststorePath
    value: /layers/paketo-buildpacks_bellsoft-liberica/jre/lib/security/cacerts 
  - name: TerrakubeRedisTruststorePassword
    value: changeit
  properties:
    redisHostname: "MY-REDIS-IN-AZURE.redis.cache.windows.net"
    redisPassword: "MY-REDIS-ACCESS-KEY"
    redisPort: "6380"

executor:
  env:
  - name: SERVICE_BINDING_ROOT
    value: /mnt/platform/bindings
  - name: TerrakubeRedisSSL
    value: "true"
  - name: TerrakubeRedisTruststorePath
    value: /layers/paketo-buildpacks_bellsoft-liberica/jre/lib/security/cacerts 
  - name: TerrakubeRedisTruststorePassword
    value: changeit
```

{% hint style="warning" %}
"changeit" is the default password for the java keystore included in the container in this path "/layers/paketo-buildpacks\_bellsoft-liberica/jre/lib/security/cacerts"
{% endhint %}

### Ephemeral Executor with Redis SSL

{% hint style="info" %}
Using EPHEMERAL\_JOB\_ENV\_VARS is supported from version 2.28.0
{% endhint %}

To add the additional environment variables to the ephemeral executor the following could be used:

Value:

```
EPHEMERAL_JOB_ENV_VARS=TerrakubeRedisSSL=true;TerrakubeRedisTruststorePath=/layers/paketo-buildpacks_bellsoft-liberica/jre/lib/security/cacerts;TerrakubeRedisTruststorePassword=changeit;ExecutorEphemeralSecret=terrakube-executor-secrets-ephemeral
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.terrakube.io/2.33.0/getting-started/deployment/external-redis.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
