### 1\. Redis

To start Redis using Docker, you can run a container from the official Redis image. Here’s a quick guide:

### 🔹 Basic Command

```bash
docker run --name redis-server -p 6379:6379 -d redis
```

### 🔍 Explanation:

* `--name redis-server`: Names the container `redis-server`.
    
* `-p 6379:6379`: Maps port 6379 from the container to your host (default Redis port).
    
* `-d`: Runs the container in detached mode (in the background).
    
* `redis`: Uses the official Redis image from Docker Hub.
