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:

Using MySQL

By default, Drone use sqlite as its database storage. To use MySQL/MariaDB instead, use -driver flag and set it to mysql. You will need to set your DSN (-datasource) in this form:

    user:password@tcp(hostname:port)/dbname?parseTime=true

Change it according to your database settings. The parseTime above is required since drone using time.Time to represents TIMESTAMP data. Please refer to [1] for more options on mysql driver.

You may also need to tweak some innodb options, especially if you're using utf8mb4 collation type.

    innodb_file_format = Barracuda
    innodb_file_per_table = On
    innodb_large_prefix = On

Please consult to the MySQL/MariaDB documentation for further information regarding large prefix for index column and dynamic row format (which is used in Drone).

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

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/

  swift:
    username: someuser
    password: 030e39a1278a18828389b194b93211aa
    auth_url: https://identity.api.rackspacecloud.com/v2.0
    region: DFW
    container: drone
    source: /tmp/drone.deb
    target: latest/drone.deb
    branch: master

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

deploy

• heroku
• git
• modulus
• nodejitsu
• ssh
• tsuru
• bash

publish

• Amazon s3
• OpenStack Swift
• PyPI

Publish plugins can be limited to a specific branch using the branch configuration as seen above in the swift example. If you do not specify a branch all branches will be published, with the exception of Pull Requests.

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

  webhook:
    on_success: true
    on_failure: true
    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.)

You can also launch custom Docker containers using standard docker notation:

services:
  - dockerfile/rethinkdb # same as dockerfile/rethinkdb:latest
  - barnybug/elasticsearch:1.0.1

NOTE 1: 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.

NOTE 2: avoid running services that use the same ports. For example, don't specify multiple versions of Elastic Search since the port will already be in use.

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

Wall display

A wall display for Drone is available as a separate service. See Drone Wall for details.

Local development

Local Drone setup for development is pretty straightforward.

You will need to clone the repo, install Vagrant and run vagrant up. This command will download base Ubuntu image, setup the virtual machine and build Drone.

Afterwards, you may vagrant ssh into the vagrant instance, where docker is already installed and ready to go.

Once in the vagrant instance, run make run, the visit http://localhost:8080/install in your browser.

The Makefile has other targets so check that out for more build, test, run configurations.
