Nomad Skeleton Driver Plugin
==========

Skeleton project for
[Nomad task driver plugins](https://www.nomadproject.io/docs/drivers/index.html).

This project is intended for bootstrapping development of a new task driver
plugin.

- Website: [https://www.nomadproject.io](https://www.nomadproject.io)
- Mailing list: [Google Groups](http://groups.google.com/group/nomad-tool)

Requirements
-------------------

- [Go](https://golang.org/doc/install) v1.18 or later (to compile the plugin)
- [Nomad](https://www.nomadproject.io/downloads.html) v0.9+ (to run the plugin)

Building the Skeleton Plugin
-------------------

[Generate](https://github.com/hashicorp/nomad-skeleton-driver-plugin/generate)
a new repository in your account from this template by clicking the `Use this
template` button above.

Clone the repository somewhere in your computer. This project uses
[Go modules](https://blog.golang.org/using-go-modules) so you will need to set
the environment variable `GO111MODULE=on` or work outside your `GOPATH` if it
is set to `auto` or not declared.

```sh
$ git clone git@github.com:<ORG>/<REPO>git
```

Enter the plugin directory and update the paths in `go.mod` and `main.go` to
match your repository path.

```diff
// go.mod

- module github.com/hashicorp/nomad-skeleton-driver-plugin
+ module github.com/<ORG>/<REPO>
...
```

```diff
// main.go

package main

import (
    log "github.com/hashicorp/go-hclog"
-   "github.com/hashicorp/nomad-skeleton-driver-plugin/hello"
+.  "github.com/<REPO>/<ORG>/hello"
...

```

Build the skeleton plugin.

```sh
$ make build
```

## Deploying Driver Plugins in Nomad

The initial version of the skeleton is a simple task that outputs a greeting.
You can try it out by starting a Nomad agent and running the job provided in
the `example` folder:

```sh
$ make build
$ nomad agent -dev -config=./example/agent.hcl -plugin-dir=$(pwd)

# in another shell
$ nomad run ./example/example.nomad
$ nomad logs <ALLOCATION ID>
```

Code Organization
-------------------
Follow the comments marked with a `TODO` tag to implement your driver's logic.

[Nomad documentation on plugins](https://www.nomadproject.io/docs/internals/plugins/index.html).
