# Helm Cheatsheet

Here is a list of commands for installing well-known charts using Helm. Most of them come from the official Bitnami repository, so you'll need to add the Bitnami repo first.

```bash
helm repo add bitnami https://charts.bitnami.com/bitnami
helm repo update
```

helm install redis bitnami/redis \

    --set fullnameOverride=redis \
    --set master.persistence.enabled=false \
    --set master.disableCommands=false
```

## Redis Sentinel
