Alternatively, you may also provide with this configuration in your [custom](https://github.com/bitnami/containers/blob/main/bitnami/redis-cluster#configuration-file) configuration file.
### Enable redis cluster RDB persistence
Since the use of `REDIS_RDB_POLICY_DISABLED` and `REDIS_RDB_POLICY` parameters is rather special, we explain it here.
When the value of `REDIS_RDB_POLICY_DISABLED` is `no` the redis default persistence strategy will be used. If you want to modify the default strategy, you can configure it through REDIS_RDB_POLICY
Here is a demonstration of modifying the default persistence strategy
1. Using `docker run`
```console
$ docker run --name redis-cluster \
-v /path/to/redis-cluster-persistence:/bitnami \
-e ALLOW_EMPTY_PASSWORD=yes \
-e REDIS_RDB_POLICY_DISABLED=no
-e REDIS_RDB_POLICY="900#1 600#5 300#10 120#50 60#1000 30#10000"
bitnami/redis-cluster:latest
```
2. Modifying the `docker-compose.yml` file present in this repository:
```yaml
redis-cluster:
...
environment:
...
- REDIS_TLS_ENABLED=yes
- REDIS_RDB_POLICY_DISABLED=no
- REDIS_RDB_POLICY="900#1 600#5 300#10 120#50 60#1000 30#10000"
...
...
```
