     9  # Rkt Driver
    10  
    11  Name: `rkt`
    12  
    13  The `Rkt` driver provides an interface for using CoreOS Rkt for running
    14  application containers. Currently, the driver supports launching
    15  containers.
    16  
    17  ## Task Configuration
    18  
    19  The `Rkt` driver supports the following configuration in the job spec:
    20  
    21  * `trust_prefix` - **(Required)** The trust prefix to be passed to rkt. Must be reachable from
    22  the box running the nomad agent.
    23  * `name` - **(Required)** Fully qualified name of an image to run using rkt
    24  * `exec` - **(Optional**) A command to execute on the ACI
    25  
    26  ## Client Requirements
    27  
    28  The `Rkt` driver requires rkt to be installed and in your systems `$PATH`.
    29  The `trust_prefix` must be accessible by the node running Nomad. This can be an
    30  internal source, private to your cluster, but it must be reachable by the client
    31  over HTTP.
    32  
    33  ## Client Attributes
    34  
    35  The `Rkt` driver will set the following client attributes:
    36  
    37  * `driver.rkt` - Set to `true` if Rkt is found on the host node. Nomad determines
    38  this by executing `rkt version` on the host and parsing the output
    39  * `driver.rkt.version` - Version of `rkt` eg: `0.8.1`
    40  * `driver.rkt.appc.version` - Version of `appc` that `rkt` is using eg: `0.8.1`
    41  
    42  ## Resource Isolation
    43  
    44  This driver does not support any resource isolation as of now.
