NAME

buildbot-worker - worker instances creation, upgrade and management

DESCRIPTION

Buildbot worker instances are located under individual folders in /var/lib/buildbot/workers. This manual explains how to manage them.

CREATION

To create a new Buildbot worker instance named $NAME, use the following commands:

buildbot-worker create-worker \

/var/lib/buildbot/workers/$NAME <master> <name> <passwd>

chown -R buildbot: /var/lib/buildbot/workers/$NAME

After which you may start the worker instance. Depending on the init system you use, this is done differently.

systemd

To start the instance:

systemctl start buildbot-worker@$NAME.service

To enable automatic start on boot:

systemctl enable buildbot-worker@$NAME.service

If you want to tune the way the instance is started (e.g., to change the user that runs the process), you may use a systemd drop-in:

mkdir -p /etc/systemd/system/buildbot-worker@$NAME.service.d
editor /etc/systemd/system/buildbot-worker@$NAME.service.d/user.conf

With the following contents:

[Service]
User=my-user
Group=my-group

sysvinit

First, you need to edit /etc/default/buildbot-worker and configure your instance. The syntax is pretty self explanatory, but here is an example:

# 1-enabled, 0-disabled
WORKER_ENABLED[1]=1
# short name printed on start/stop
WORKER_NAME[1]="$NAME"
# user to run worker as
WORKER_USER[1]="buildbot"
# basedir to worker (absolute path)
WORKER_BASEDIR[1]="/var/lib/buildbot/workers/$NAME"
# buildbot-worker options
WORKER_OPTIONS[1]=""
# prefix command, i.e. nice, linux32, dchroot
WORKER_PREFIXCMD[1]=""

After which, you may start the instance:

service buildbot-worker start $NAME

By default, it will automatically start on boot.

UPGRADE

When installing new versions, each worker instance is automatically restarted. No additional action is required.

upgrade from 0.8.x

Since version 0.9.0 of Buildbot "slave"-based terminology is deprecated in favor of "worker"-based terminology.

If you are upgrading from a 0.8.x version, all old buildbot-slave instances in /var/lib/buildbot/slaves must be manually migrated. The simplest way of doing that is to create new workers re-using the same <master>, <name> and <passwd> arguments. See the CREATION section of this manual for more details.

Once migrated, you may safely delete the old "slave" directory:

rm -rf /var/lib/buildbot/slaves/$NAME

FILES

/var/lib/buildbot/workers/$NAME

Working directory for the $NAME Buildbot worker instance.

/etc/systemd/system/buildbot-worker@$NAME.service.d

Directory containing customization drop-ins for the $NAME Buildbot worker instance service.

/etc/default/buildbot-worker

The worker instances services definition for sysvinit users.
