Onde ficam os arquivos do Docker volume?

$ docker volume ls
DRIVER    VOLUME NAME
local     vol1

$ docker volume inspect vol1
[
    {
        "CreatedAt": "2024-08-25T13:17:24-03:00",
        "Driver": "local",
        "Labels": null,
        "Mountpoint": "/var/lib/docker/volumes/vol1/_data",
        "Name": "vol1",
        "Options": null,
        "Scope": "local"
    }
]

$ sudo tree /var/lib/docker/
volumes/vol1/
/var/lib/docker/volumes/vol1/
└── _data
