Install Drone

To use the custom service (as I did with elasticsearch) you have to install drone from source using my fork (https://github.com/xpepper/drone) which BTW merges the work done by @yosssi (yosssi/custom-services).

Install Go 1.2

So prepare to install Go 1.2: use godeb if you want an easy way to do that, or follow this guide.

Than add these two lines in your .profile

export GOPATH=$HOME/go
export PATH=$GOPATH/bin:$PATH

Install Drone from source

To install Drone from source, follow their guide: http://drone.readthedocs.org/en/latest/install.html#from-source. Remember though, the cloned repo should be https://github.com/xpepper/drone and it should be put under go/src/github.com/drone so that the make command can succeeed.

Alternative installation

Executing make install will install drone in

• /usr/local/bin
• /etc/init/drone.conf
• /etc/defaults/drone

While make dpkg will build the .deb package.

Running drone as a non-root user

1. groupadd docker
2. useradd --system -d /var/lib/drone -s /bin/false -G docker drone
3. restart docker with service docker restart
4. add these lines in /etc/init.drone.conf (under "console log")

setuid drone
setgid drone

Running Drone

To run Drone easily, we symlinked the two binaries (drone and droned)

ln -s $GOPATH/src/github.com/drone/drone/bin/drone $GOPATH/bin/
ln -s $GOPATH/src/github.com/drone/drone/bin/droned $GOPATH/bin/

To start Drone, we use the start-droned.sh script listed below.

Drone SMTP configuration with GMAIL

To configure Drone to send email using a Gmail account, fill the Settings section with there values

• SMTP Server: smtp.gmail.com
• SMTP Port: 587
• SMTP From Address: <my_account>@gmail.com
• SMTP Username and Password: <my_account>@gmail.com / <my_password>

Then follow this link to allow Drone to send mail: https://accounts.google.com/b/0/DisplayUnlockCaptcha

Misc

Logs are under /var/log/upstart/drone.log and /var/log/upstart/docker.log.
