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.
