```
$ curl localhost:5000

## Monitoring Redis keys
Connect to redis database by using ```redis-cli``` command and monitor the keys.
```

```
The compose file defines an application with four services `redis`, `nginx`, `web1` and `web2`.
When deploying the application, docker-compose maps port 80 of the nginx service container to port 80 of the host as specified in the file.
> ℹ️ **_INFO_**
> Redis runs on port 6379 by default. Make sure port 6379 on the host is not being used by another container, otherwise the port should be changed.
## Deploy with docker-compose

## Expected result

```

```
curl localhost:80
