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:

$ 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:

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

Here is a list of our official images:

# 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
docker pull bradrydzewski/lein             # image: lein

# dart images
docker pull bradrydzewski/dart:stable      # image: dart

docker pull bradrydzewski/erlang:R16B      # image: erlangR16B
docker pull bradrydzewski/erlang:R16B02    # image: erlangR16B02
docker pull bradrydzewski/erlang:R16B01    # image: erlangR16B01

# gcc images (c/c++)
docker pull bradrydzewski/gcc:4.6          # image: gcc4.6
docker pull bradrydzewski/gcc:4.8          # image: gcc4.8

# go images
docker pull bradrydzewski/go:1.0           # image: go1
docker pull bradrydzewski/go:1.1           # image: go1.1
docker pull bradrydzewski/go:1.2           # image: go1.2

# haskell images
docker pull bradrydzewski/haskell:7.4      # image: haskell

# java and jdk images
docker pull bradrydzewski/java:openjdk6    # image: openjdk6
docker pull bradrydzewski/java:openjdk7    # image: openjdk7
docker pull bradrydzewski/java:oraclejdk7  # image: oraclejdk7
docker pull bradrydzewski/java:oraclejdk8  # image: oraclejdk8

# node images
docker pull bradrydzewski/node:0.10        # image node0.10
docker pull bradrydzewski/node:0.8         # image node0.8

# 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:3.3       # image: python3.3
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
• git
• modulus
• ssh

publish

• Amazon s3

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
