Bitnami will release a new chart updating its containers if a new version of the main container, significant changes, or critical vulnerabilities exist.

### Production configuration and horizontal scaling

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`. You can use this file instead of the default one.

- Number of NATS nodes

```diff
- replicaCount: 1
+ replicaCount: 3
```

- Enable and set the max. number of client connections, protocol control line, payload and duration the server can block on a socket write to a client

```diff
- # maxConnections: 100
- # maxControlLine: 512
- # maxPayload: 65536
- # writeDeadline: "2s"
+ maxConnections: 100
+ maxControlLine: 512
+ maxPayload: 65536
+ writeDeadline: "2s"
```

- Enable NetworkPolicy:

```diff
- networkPolicy.enabled: false
+ networkPolicy.enabled: true
```

- Disallow external connections:

```diff
- networkPolicy.allowExternal: true
+ networkPolicy.allowExternal: false
```

- Enable ingress controller resource:

```diff
- ingress.enabled: false
+ ingress.enabled: true
```

- Enable Prometheus metrics via exporter side-car:

```diff
- metrics.enabled: false
+ metrics.enabled: true
```

- Enable PodDisruptionBudget:

```diff
- pdb.create: false
+ pdb.create: true
```

To horizontally scale this chart, you can use the `--replicas` flag to modify the number of nodes in your NATS replica set.

### Adding extra environment variables

In case you want to add extra environment variables (useful for advanced operations like custom init scripts), you can use the `extraEnvVars` property.
