[Serverspec](http://serverspec.org/) / [Specinfra](https://github.com/mizzy/specinfra) backend for Docker `nsenter` execution driver.

## Requirements

* Recommended Docker `1.7.0` or higher.
* `sudo` installed (not in the container).
* `nsenter` binary installed.

## Installation

Add this line to your application's Gemfile:

```ruby
# Gemfile

gem 'specinfra-backend-docker_nsenter', '~> 0.1.0'
```

And then execute:

    $ bundle

Or install it yourself as:

    $ gem install specinfra-backend-docker_nsenter

## Usage

```ruby
require 'serverspec'
require 'specinfra/backend/docker_nsenter'

set :docker_image, ENV['DOCKER_IMAGE_ID']
set :backend, :docker_nsenter

describe 'Dockerfile run' do
  describe service('httpd') do
    it { should be_enabled }
    it { should be_running }
  end
end
```

## Configuration

Uses the following `Specinfra` configuration options:

- `:sudo_options`: Sudo command argument list as string or as array.
- `:sudo_path`: Sudo binary directory.
- `:sudo_password`
- `:disable_sudo`: whether to disable Sudo (enabled by default).

For example:

```ruby
set :sudo_password, 'fBQ6MB5e7mKUt1X7cNAq'
```
