This project is a [Hashicorp Nomad](https://www.nomadproject.io/) [task driver
|
|
|
|
|
plugin](https://www.nomadproject.io/docs/drivers/index.html) skeleton
|
|
|
|
|
implementation. You can clone and modify this to get started writing your own
|
|
|
|
|
task driver plugin.

The initial state of the skeleton is a simple task that outputs a greeting. You
|
|
|
|
|
can try it out by starting a Nomad server and client and running the job
|
|
|
|
|
provided in the `config` folder:
|
2019-09-30 15:26:20 +00:00
|
|
|
|
|
|
|
|
```sh
|
2019-11-29 23:58:03 +00:00
|
|
|
go build
|
|
|
|
|
nomad agent -dev -config=./config/client.hcl -plugin-dir=$(PWD)
|
|
|
|
|
|
|
|
|
|
# in another shell
|
|
|
|
|
nomad run ./config/example.nomad
|
2019-09-30 15:26:20 +00:00
|
|
|
```

|
You should rename the project's root folder and the `hello` module to fit your
|
|
|
|
|
own driver.

Code Organization

2019-11-29 23:58:03 +00:00
|
|
|
-------------------
|
|
|
|
|
The skeleton driver comes with an in memory task state store (see
|
|
|
|
|
`hello/state.go`). This in-memory map is for storing runtime details (like a
|
|
|
|
|
process id). The details of what to store is left to the implementation of the
|
|
|
|
|
task driver. Fields stored in the base implementation in this skeleton can be
|
|
|
|
|
found in the `taskHandle` struct.
