# nomad
Where the wild bits roam
Nomad [![Build Status](https://travis-ci.org/hashicorp/nomad.svg)](https://travis-ci.org/hashicorp/nomad)
=========
- Website: https://www.nomadproject.io
- IRC: `#nomad-tool` on Freenode
- Mailing list: [Google Groups](https://groups.google.com/group/nomad-tool)
![Nomad](https://raw.githubusercontent.com/hashicorp/nomad/master/website/source/assets/images/logo-header%402x.png?token=AAkIoLO_y1g3wgHMr3QO-559BN22rN0kks5V_2HpwA%3D%3D)
Nomad is a cluster manager, designed for both long lived services and short
lived batch processing workloads. Developers use a declarative job specification
to submit work, and Nomad ensures constraints are satisfied and resource utilization
is optimized by efficient task packing. Nomad supports all major operating systems
and virtualized, containerized, or standalone applications.
The key features of Nomad are:
* **Docker Support**: Jobs can specify tasks which are Docker containers.
Nomad will automatically run the containers on clients which have Docker
installed, scale up and down based on the number of instances request,
and automatically recover from failures.
* **Multi-Datacenter and Multi-Region Aware**: Nomad is designed to be
a global-scale scheduler. Multiple datacenters can be managed as part
of a larger region, and jobs can be scheduled across datacenters if
requested. Multiple regions join together and federate jobs making it
easy to run jobs anywhere.
* **Operationally Simple**: Nomad runs as a single binary that can be
either a client or server, and is completely self contained. Nomad does
not require any external services for storage or coordination. This means
Nomad combines the features of a resource manager and scheduler in a single
system.
* **Distributed and Highly-Available**: Nomad servers cluster together and
perform leader election and state replication to provide high availability
in the face of failure. The Nomad scheduling engine is optimized for
optimistic concurrency allowing all servers to make scheduling decisions to
maximize throughput.
* **HashiCorp Ecosystem**: Nomad integrates with the entire HashiCorp
ecosystem of tools. Along with all HashiCorp tools, Nomad is designed
in the unix philosophy of doing something specific and doing it well.
Nomad integrates with tools like Packer, Consul, and Terraform to support
building artifacts, service discovery, monitoring and capacity management.
For more information, see the [introduction section](https://www.nomadproject.io/intro)
of the Nomad website.
Getting Started & Documentation
-------------------------------
All documentation is available on the [Nomad website](https://www.nomadproject.io).
Developing Nomad
--------------------
If you wish to work on Nomad itself or any of its built-in systems,
you'll first need [Go](https://www.golang.org) installed on your
machine (version 1.4+ is *required*).
For local dev first make sure Go is properly installed, including setting up a
[GOPATH](https://golang.org/doc/code.html#GOPATH). After setting up Go, you can
download the required build tools such as vet, cover, godep etc by bootstrapping
your environment.
```sh
$ make bootstrap
...
```
Next, clone this repository into `$GOPATH/src/github.com/hashicorp/nomad`.
Then type `make test`. This will run the tests. If this exits with exit status 0,
then everything is working!
```sh
$ make test
...
```
To compile a development version of Nomad, run `make`. This will put the
Nomad binary in the `bin` and `$GOPATH/bin` folders:
```sh
$ make
...
$ bin/nomad
...
```

# Nomad Website
This subdirectory contains the entire source for the [Nomad Website](https://nomadproject.io/).
This is a [Middleman](http://middlemanapp.com) project, which builds a static
site from these source files.
## Contributions Welcome!
If you find a typo or you feel like you can improve the HTML, CSS, or
JavaScript, we welcome contributions. Feel free to open issues or pull
requests like any normal GitHub project, and we'll merge it in.
## Running the Site Locally
Running the site locally is simple. Clone this repo and run the following
commands:
```
$ bundle
$ bundle exec middleman server
```
Then open up `http://localhost:4567`. Note that some URLs you may need to append
".html" to make them work (in the navigation).
