### System

Drone is tested on the following versions of Ubuntu:

* Ubuntu Precise 12.04 (LTS) (64-bit)
* Ubuntu Raring 13.04 (64 bit)

Drone's only external dependency is the latest version of Docker (0.8)

### Setup

Drone is packaged and distributed as a debian file. You can download an install
using the following commands:

```sh
$ wget http://downloads.drone.io/latest/drone.deb
$ sudo dpkg -i drone.deb
$ sudo start drone
```

Once Drone is running (by default on :80) navigate to **http://localhost:80/install**
and follow the steps in the setup wizard.

**IMPORTANT** You will also need a GitHub Client ID and Secret:

* Register a new application https://github.com/settings/applications
* Set the homepage URL to http://$YOUR_IP_ADDRESS/
* Set the callback URL to http://$YOUR_IP_ADDRESS/auth/login/github
* Copy the Client ID and Secret into the Drone admin console http://localhost:80/account/admin/settings

I'm working on a getting started video. Having issues with volume, but hopefully
you can still get a feel for the steps:

### Builds

Drone use a **.drone.yml** configuration file in the root of your
repository to run your build:

```
image: mischief/docker-golang
env:
  - GOPATH=/var/cache/drone
script:
  - go build
  - go test -v
services:
  - redis
notify:
  email:
    recipients:
      - brad@drone.io
      - burke@drone.io
```

### Images

In the above example we used a custom Docker image from index.docker.io **mischief/docker-golang**

Drone also provides official build images. These images are configured specifically for CI and
have many common software packages pre-installed (git, xvfb, firefox, libsqlite, etc).

Official Drone images are referenced in the **.drone.yml** by an alias:

```sh
image: go1.2   # same as bradrydzewski/go:1.2
```

Here is a list of our official images:

```sh
# these two are base images. all Drone images are built on top of these
# these are BIG (~3GB) so make sure you have a FAST internet connection
docker pull bradrydzewski/ubuntu
docker pull bradrydzewski/base

# clojure images

# gcc images (c/c++)

docker pull bradrydzewski/java:oraclejdk8  # image: oraclejdk8

# node images
docker pull bradrydzewski/node:0.10        # image node0.10

# php images
docker pull bradrydzewski/php:5.5          # image: php5.5
docker pull bradrydzewski/php:5.4          # image: php5.4

# python images

docker pull bradrydzewski/python:pypy      # image: pypy

# ruby images
docker pull bradrydzewski/ruby:2.0.0       # image: ruby2.0.0
docker pull bradrydzewski/ruby:1.9.3       # image: ruby1.9.3

# scala images
docker pull bradrydzewski/scala:2.10.3     # image: scala2.10.3
docker pull bradrydzewski/scala:2.9.3      # image: scala2.9.3

```

### Environment

Drone clones your repository into a Docker container
at the following location:

```
/var/cache/drone/src/github.com/$owner/$name
```

Please take this into consideration when setting up your build commands, or
if you are using a custom Docker image.

### Git Command Options

You can specify the `--depth` option of the `git clone` command (default value is `50`):

```
git:
  depth: 1
```

### Deployments

Drone can trigger a deployment at the successful completion of your build:

```
deploy:
  heroku:
    app: safe-island-6261

publish:
  s3:
    acl: public-read
    region: us-east-1
    bucket: downloads.drone.io
    access_key: C24526974F365C3B
    secret_key: 2263c9751ed084a68df28fd2f658b127
    source: /tmp/drone.deb
    target: latest/

```

Drone currently has these `deploy` and `publish` plugins implemented (more to come!):

**deploy**
- [heroku](#docs)
- [git](#docs)
- [modulus](#docs)
- [ssh](#docs)

**publish**
- [Amazon s3](#docs)

### Notifications

Drone can trigger email, hipchat and web hook notification at the beginning and
completion of your build:

```
notify:
  email:
    recipients:
      - brad@drone.io
      - burke@drone.io

  urls:
    - http://my-deploy-hook.com

  hipchat:
    room: support
    token: 3028700e5466d375
    on_started: true
    on_success: true
    on_failure: true
```

### Databases

Drone can launch database containers for your build:

```
services:
  - cassandra
  - couchdb
  - couchdb:1.0
  - couchdb:1.4
  - couchdb:1.5
  - elasticsearch
  - elasticsearch:0.20
  - elasticsearch:0.90
  - neo4j
  - neo4j:1.9
  - mongodb
  - mongodb:2.2
  - mongodb:2.4
  - mysql
  - mysql:5.5
  - postgres
  - postgres:9.1
  - rabbitmq
  - rabbitmq:3.2
  - redis
  - riak
  - zookeeper
```

If you omit the version, Drone will launch the latest version of the database. (For example, if you set `mongodb`, Drone will launch MongoDB 2.4.)

**NOTE:** database and service containers are exposed over TCP connections and
have their own local IP address. If the **socat** utility is installed inside your
Docker image, Drone will automatically proxy localhost connections to the correct
IP address.

### Caching

Drone can persist directories between builds. This should be used for caching dependencies to
decrease overall build time. Examples include your `.npm`, `.m2`, `bundler`, etc.

```
cache:
  - /usr/local/bin/go/pkg                  
```

This will cache the directory relative to the root directory of your repository:

```
cache:
  - .npm
```

**NOTE:** this is an alpha quality feature and still has some quirks. See https://github.com/drone/drone/issues/147

### Params Injection

You can inject params into .drone.yml.

```
notify:
  hipchat:
    room: {{hipchatRoom}}
    token: {{hipchatToken}}
    on_started: true
    on_success: true
    on_failure: true
```
