### Production configuration
This chart includes a `values-production.yaml` file where you can find some parameters oriented to production configuration in comparison to the regular `values.yaml`:
- Desired number of Elasticsearch master-eligible nodes:
```diff
- master.replicas: 2
+ master.replicas: 3
```
- Enable the liveness probe (master-eligible nodes pod):
```diff
- master.livenessProbe.enabled: false
- # initialDelaySeconds: 90
- # periodSeconds: 10
- # timeoutSeconds: 5
- # successThreshold: 1
- # failureThreshold: 5
+ master.livenessProbe.enabled: true
+ initialDelaySeconds: 90
+ periodSeconds: 10
+ timeoutSeconds: 5
+ successThreshold: 1
+ failureThreshold: 5
```
- Enable the readiness probe (master-eligible nodes pod):
```diff
- master.readinessProbe.enabled: false
- # initialDelaySeconds: 90
- # periodSeconds: 10
- # timeoutSeconds: 5
- # successThreshold: 1
- # failureThreshold: 5
+ master.readinessProbe.enabled: true
+ initialDelaySeconds: 90
+ periodSeconds: 10
+ timeoutSeconds: 5
+ successThreshold: 1
+ failureThreshold: 5
```
- Desired number of Elasticsearch coordinating-only nodes:
```diff
- data.replicas: 2
+ data.replicas: 3
```
- Enable the liveness probe (coordinating-only nodes pod):
```diff
- coordinating.livenessProbe.enabled: false
- # initialDelaySeconds: 90
- # periodSeconds: 10
- # timeoutSeconds: 5
- # successThreshold: 1
- # failureThreshold: 5
+ coordinating.livenessProbe.enabled: true

- Enable ingest nodes:
```diff
- ingest.enabled: false
+ ingest.enabled: true
```
- Desired number of Elasticsearch ingest nodes:
```diff
- data.replicas: 2
+ data.replicas: 3
```
- Enable the liveness probe (ingest nodes pod):

+ metrics.enabled: true
```
### [Rolling VS Immutable tags](https://docs.bitnami.com/containers/how-to/understand-rolling-tags-containers/)
It is strongly recommended to use immutable tags in a production environment. This ensures your deployment does not change automatically if the same tag is updated with a different image.
