# `volume_mount` Stanza

<Placement groups={['job', 'group', 'task', 'volume_mount']} />

The `volume_mount` stanza allows the task to specify how a group
[`volume`][volume] should be mounted into the task.

```hcl
job "docs" {
  group "example" {
    volume "certs" {
      type = "host"
      read_only = true
      source = "ca-certificates"
    }

    task "example" {
      volume_mount {
        volume      = "certs"
        destination = "/etc/ssl/certs"
      }
    }
  }
}
```

The Nomad client will make the volumes available to tasks according to this
configuration, and it will fail the allocation if the client configuration
updates to remove a volume that it depends on.

## `volume_mount` Parameters

- `volume` `(string: "")` - Specifies the group volume that the mount is going
  to access.

- `destination` `(string: "")` - Specifies where the volume should be mounted
  inside the task's allocation.

- `read_only` `(bool: false)` - When a group volume is writeable, you may
  specify that it is `read_only` on a per mount level using the `read_only`
  option here.
