    a: "Yes. Dragonfly is Redis-compatible - a drop-in replacement that works with any Redis client library (ioredis, redis-py, Sidekiq…)."
  - q: "What is Dragonfly good for?"
    a: "Caching, session storage, queues, rate limiting - any workload where you'd normally reach for Redis, with a multi-threaded architecture that's faster for many workloads."
  - q: "How does my app connect?"
    a: "Link HOST and PORT (6379), or map them into a single REDIS_URL=redis://HOST:PORT. Your app redeploys and the values become accessible."

Provision a [Dragonfly](https://github.com/dragonflydb/dragonfly) - a modern, Redis-compatible in-memory store - inside your Rock8Cloud project and connect it to your app **in one click**. Use it for caching, sessions, and queues with any Redis client.

## Provision and connect in one click



[Pick the engine and provision it in one click](https://minio.11333311.xyz/vibeham-docs/db_selection.mp4)



1. **Add a service.** In your project, click **Add Service → Database → Dragonfly** and pick a storage size.
2. **Link it.** Open your app's **Env vars** tab and add the connection variables under the names your framework expects.
3. **Save.** Your app automatically redeploys - connected.

## Connect from your app

When you link the database, you name the variable yourself. Most Redis clients expect `REDIS_URL`, so link the **Connection URL** under that name:

```bash
# You choose the name when linking - e.g.
REDIS_URL   # → redis://HOST:PORT
```

Linking the connection URL also adds its building blocks automatically - `REDIS_HOST` and `REDIS_PORT` appear alongside it, ready to use individually.

When you link, you pick what the variable maps to - Dragonfly offers:

| Link option | Maps to |
|---|---|
| Host | auto-generated hostname |
| Port | `6379` |
| Connection URL | `redis://HOST:PORT` |

Any Redis client accepts these directly. The instance is network-isolated to your project - reachable by your services, never exposed publicly.
