nomad-driver-winsvc

A task driver plugin to orchestrate Windows Services as Hashicorp Nomad job tasks.

Requirements

• Nomad v0.9+
• Go v1.11+ (to build the provider plugin)
• Windows Server 2016+

Configuring the Plugin

A task is configured using the below options:

Option	Type	Description
executable	string	Path to executable binary
args	[]string	Command line arguments to pass to executable
username	string	Name of the account under which the service should run
password	string	Password of the account

Example Job

PS> nomad job run example/example.nomad

When run, the above example job will result in the creation of (2) services each named to reflect their respective JobName & AllocID values:

PS❯ get-service nomad.winsvc.* | select Status, Name, BinaryPathName

Status  Name                                                        BinaryPathName
------  ----                                                        --------------
Running nomad.winsvc.example.e402ad0a-7d7d-e72e-1823-64ba5ded3711   c:\hashicorp\nomad\data\alloc\e402ad0a-7d7d-e72e-1823-64ba5ded3711\task\local\example.exe
Running nomad.winsvc.example.c59a986f-6e14-f14f-d1ac-593cd86025b7   c:\hashicorp\nomad\data\alloc\c59a986f-6e14-f14f-d1ac-593cd86025b7\task\local\example.exe

Stopping the job will result in the graceful stop and eventual removal of the services as the Nomad job completes and gc is run.

TODO

1. Support running as LOCALSYSTEM (perhaps just as default when username is nil)
2. Document how to pass password through environment variables rather than exposed in job file
3. Document how to support TopShelf services
