A [Chef](https://www.chef.io/) cookbook to handle deploying code from git when
using the [application cookbook](https://github.com/poise/application).

## Quick Start

To deploy from a private GitHub repository:

```ruby
application '/srv/myapp' do
  git 'git@github.com:example/myapp.git' do
    deploy_key chef_vault_item('deploy_keys', 'myapp')['key']
  end
end
```

## Requirements

Chef 12 or newer is required.

## Resources

### `application_git`

The `application_git` resource deploys code from git. It extends the core `git`
resource to support deploy keys and disabling strict host key verification.

```ruby
application '/srv/myapp' do
  git 'git@github.com:example/myapp.git'
end
```

#### Actions

All actions work the same as the core `git` resource.

* `:sync` – Clone and checkout the requested revision *(default)*
* `:checkout` – Checkout the request revision. If the repository isn't already
  cloned, this action does nothing.
* `:export` – Export the repository without the `.git` folder.

#### Properties

All properties from the core `git` resource work the same way with the following
additions:

* `deploy_key` – SSH key to use with git. Can be specified either as a path to
  key file already created or as a string value containing the key directly.
* `strict_ssh` – Enable strict SSH host key checking. *(default: false)*

### DSL Usage

The `application_git` resource can be used directly as a replacement for the
core `git` resource:

```ruby
application_git '/srv/myapp' do
  repository 'git@github.com:example/myapp.git'
  deploy_key chef_vault_item('deploy_keys', 'myapp')['key']
end
```

Within the `application` resource, a simplified DSL is available. As with other
`application` plugins, the default name of the resource if unspecified is the
application path. The following two examples are equivalent:

```ruby
application '/srv/myapp' do
  git do
    repository 'git@github.com:example/myapp.git'
  end
end

application '/srv/myapp' do
  git 'git@github.com:example/myapp.git'
end
```
