Docker-compose - volumes driver local meaning

Question

I'm making some docker-compose yml file with this link. In this config, what does `driver: local` in top-level volumes mean? ``` volumes: esdata1: driver: local esdata2: driver: local ```

Accepted Answer

It's volume driver, equivalent to

```
docker volume create --driver local --name esdata1
docker volume create --driver local --name esdata2
```

`local` means the volumes esdata1 and esdata2 are created on the same Docker host where you run your container. By using other Volume plugins, e.g.,

```
--driver=flocker
```

you are able to create a volume on a external host and mount it to the local host, say, `/data-path`. So, when your container writes to `/data-path`, it actually writes to a external disk via network.
