# `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.
