Buildbot in the examples.

I needed to set up the process of building and delivering software packages from a Git repository to the website. Recently, I came across an article about buildbot here on Habr (link at the end) and decided to try it out for this purpose.

Since buildbot is a distributed system, it makes sense to create a separate build host for each architecture and operating system. In our case, these will be LXC containers (for Linux) and qemu (for Windows):

  • vm-srv-build1 β€” CentOS 7, where the buildbot master will reside along with one worker
  • vm-srv-build2 β€” Debian 10, for building DEB packages
  • vm-srv-build3 β€” Windows 10, for building, you know what for

We will be building Rac GUI β€” a graphical interface for 1C rac for managing a server cluster. Standard tools will be used for Linux for each OS, while building an exe file for Windows from a tcl script involves using freewrap.

Installation

GNU/Linux

There is plenty of installation documentation available online. 1,2And it doesn't present any particular problems:
For the master:

pip3 install buildbot
pip3 install twisted
pip3 install autobahn
pip3 install pysqlite3
pip3 install sqlalchemy sqlalchemy-migrate
pip3 install buildbot-www buildbot-grid-view buildbot-console-view buildbot-waterfall-view
pip3 install python-dateutil

For the workers, this is sufficient:

pip3 install buildbot-worker

Of course, it would be more appropriate to build packages for each OS, but that is beyond the scope of this article. I will also skip the description of configuring containers for operation, just note that I use ProxMox VE. Additionally, it will be necessary to install the packages required for building on each OS (CentOS: rpmdevtools, etc.; Debian: build-essential, dh-make, pbuilder, etc.)

The project builds and buildbot services will run under an unprivileged user, so it is necessary to create one on all hosts involved in the process:


adduser buildbot

Next, we will configure the automatic startup of services accordingly on each of the hosts (containers):

Systemd unit for starting the master:

touch /etc/systemd/buildbot-master.service

[Unit]
Description=BuildBot master service
After=network.target

[Service]
User=buildbot
Group=buildbot
WorkingDirectory=/home/buildbot/master
ExecStart=/usr/local/bin/buildbot start --nodaemon
ExecReload=/bin/kill -HUP $MAINPID

[Install]
WantedBy=multi-user.target

and the 'worker'

touch /etc/systemd/buildbot-worker.service

[Unit]
Description=BuildBot worker service
After=network.target

[Service]
User=buildbot
Group=buildbot
WorkingDirectory=/home/buildbot/worker
ExecStart=/usr/local/bin/buildbot-worker start --nodaemon

[Install]
WantedBy=buildbot-master.service

Since all scripts (in our case) are located in /usr/local/, we should define the path to them in the environment variables:

nano /root/.bash_profile

PATH=$PATH:$HOME/.local/bin:$HOME/bin:/usr/local/bin

After that, you can create the directory infrastructure for the 'workers' (on all hosts) by registering as the buildbot user and executing the following commands:

On the first host vm-srv-build1:

su - buildbot
mkdir /home/buildbot/worker
cd ~
buildbot-worker create-worker --umask=0o22 --keepalive=60 worker vm-srv-build1:4000 CentOS 123456

On the second host vm-srv-build2:

su - buildbot
mkdir /home/buildbot/worker
cd ~
buildbot-worker create-worker --umask=0o22 --keepalive=60 worker vm-srv-build1:4000 Debian-10 123456

On the worker hosts, the buildbot-worker service can be started

systemctl start buildbot-worker

MS Windows

As a 'worker' for building under Windows, a virtual machine with the latest release of Win10 will be used.
The following will be required:

Once all of the above is installed, you can install buildbot itself:

pip install buildbot-worker

Let's create a working directory

md c:worker

And start it

buildbot-worker start c:worker

If everything works (see log c:workertwistd.log), you can register our 'worker' as a service by adding an entry in the registry with the working directory (the commands are executed in PowerShell run as administrator):

buildbot_worker_windows_service.exe --user VM-SRV-BUILD3buildbot --password 123456 --startup auto install
New-ItemProperty -path Registry::HKEY_LOCAL_MACHINESYSTEMCurrentControlSetservicesBuildBotParameters -Name directories -PropertyType String -Value c:worker

And you can start the service

Start-Service buildbot

That's all for the 'workers', they can be left alone now, all management is done from the master.

Configuring the Master

To start, let's create the infrastructure for the master (on the main host) by registering as the buildbot user and executing the following commands:

su - buildbot
mkdir /home/buildbot/master
cd ~
buildbot create-master master

To create ready packages, let's create a builds directory

mkdir /home/buildbot/builds

In the /home/buildbot/master/ directory, a file master.cfg was created. This file is a Python script and contains a description of all the system's working mechanisms, and we will work with it further.

nano /home/buildbot/master/master.cfg

import os, re
from buildbot.plugins import steps, util, schedulers, worker, changes, reporters

c= BuildmasterConfig ={}

# Description of our workers.
c['workers'] = [ worker.Worker('CentOS', '123456'), worker.Worker('Debian-10', '123456'), worker.Worker('Windows-10', '123456')]
c['protocols'] = {'pb': {'port': 4000}} 

# Indicating to the master which repository to monitor
c['change_source'] = []
c['change_source'].append(changes.GitPoller(
       repourl = 'https://bitbucket.org/svk28/rac-gui.git',
       project = 'Rac-GUI',
       branches = True,
       pollInterval = 60
      )
)

# Build trigger service
c['schedulers'] = []
c['schedulers'].append(schedulers.SingleBranchScheduler(
       name="Rac-GUI-schedulers",
       change_filter=util.ChangeFilter(branch='master'),
       builderNames=["Rac-GUI-RPM-builder", "Rac-GUI-DEB-builder", "Rac-GUI-WIN-builder"],
       properties = {'owner': 'admin'}
       )
)
@util.renderer

######################################3
# Building RPM package
 rac_gui_build_RPM = util.BuildFactory()

rac_gui_build_RPM.addStep(steps.Git(
       repourl = 'https://bitbucket.org/svk28/rac-gui.git',
       workdir = 'rac-gui',
       haltOnFailure = True,
       submodules = True,
       mode='full',
       progress = True)
)

To automate the building of packages of different versions, so that it is not necessary to delve into the code of the master.cfg file, the main script rac_gui.tcl has been updated with lines indicating the current version and release:

######################################################
#        Rac GUI
...
# version: 1.0.3
# release: 1

And based on these lines, buildbot will number the packages. To extract the data, the console command grep is used. In buildbot, you cannot simply define variables for the 'workers' (at least, I couldn't find how). For this, properties serve the purpose. That is, we add steps in the build process to define the version and release, and accordingly, set the properties version and release. Properties can be set in various ways; in this case, it is through a console command call:

# Π”ΠΎΠ±Π°Π²ΠΈΠΌ ΠΎΠΏΡ€Π΅Π΄Π΅Π»Π΅Π½ΠΈΠ΅ вСрсии ΠΈΠ· основного Ρ„Π°ΠΉΠ»Π°
rac_gui_build_RPM.addStep(
       steps.SetPropertyFromCommand(
       command="grep version ../rac-gui/rac_gui.tcl | grep -oE 'b[0-9]{1,2}.[0-9]{1,2}.[0-9]{1,2}b'", property="version"
       )
)
# Π”ΠΎΠ±Π°Π²ΠΈΠΌ ΠΎΠΏΡ€Π΅Π΄Π΅Π»Π΅Π½ΠΈΠ΅ Ρ€Π΅Π»ΠΈΠ·Π° ΠΈΠ· основного Ρ„Π°ΠΉΠ»Π°
rac_gui_build_RPM.addStep(
       steps.SetPropertyFromCommand(
       command="grep release ../rac-gui/rac_gui.tcl | grep -oE 'b[0-9]{1,3}b'", property="release"
       )
)

The obtained values can be substituted using util.Interpolate().

# Π—Π°ΠΏΠ°ΠΊΡƒΠ΅ΠΌ исходники
rac_gui_build_RPM.addStep(
       steps.ShellCommand(
          command=["tar", "czf", util.Interpolate("/home/buildbot/rpmbuild/SOURCES/rac-gui-%(prop:version)s-%(prop:release)s.tar.gz"), "../rac-gui"]
       )
)

It should be noted that, since the host is also used for manual package building, the build will proceed along the standard paths.

# ΠšΠΎΠΏΠΈΡ€ΡƒΠ΅ΠΌ spec
rac_gui_build_RPM.addStep(steps.ShellCommand(
       command=["cp", "../rac-gui/rac_gui.spec", "/home/buildbot/rpmbuild/SPECS/rac_gui.spec"]))

To set the correct release and version numbers, the standard sed call is used; that is, the command replaces the values inside the spec file with the necessary ones.

# мСняСм Π²Π΅Ρ€ΡΠΈΡŽ
rac_gui_build_RPM.addStep(steps.ShellCommand(
       command=["sed", "-i", util.Interpolate("s/.*Version:.*/Version:t%(prop:version)s/"), "/home/buildbot/rpmbuild/SPECS/rac_gui.spec"]))
# мСняСм Ρ€Π΅Π»ΠΈΠ·

# запускаСм процСсс сборки
rac_gui_build_RPM.addStep(steps.RpmBuild(

       rpmdir='/home/buildbot/rpmbuild/RPMS',
       sourcedir='/home/buildbot/rpmbuild/SOURCES'
      )
)

The finished package and the source archive are copied to the master. However, it is also possible to copy directly from the working files to your repository or website.

          masterdest=util.Interpolate("/home/buildbot/builds/rac-gui-%(prop:version)s-%(prop:release)s.noarch.rpm")

          masterdest=util.Interpolate("/home/buildbot/builds/rac-gui-%(prop:version)s-%(prop:release)s.tar.gz")
       )
)

Let's start the process on the master to copy the built packages to the hosting via FTP. For this purpose, we use a script in tcl.

rac_gui_build_RPM.addStep(
        steps.MasterShellCommand(
            command=["/usr/local/bin/deploy-ftp.tcl",
                util.Interpolate("--local-file=/home/buildbot/builds/rac-gui-%(prop:version)s-%(prop:release)s.noarch.rpm"),
                util.Interpolate("--remote-file=uploads/rac-gui/rac-gui-%(prop:version)s-%(prop:release)s.noarch.rpm")]
        )
)

rac_gui_build_RPM.addStep(
        steps.MasterShellCommand(
            command=["/usr/local/bin/deploy-ftp.tcl",
                util.Interpolate("--local-file=/home/buildbot/builds/rac-gui-%(prop:version)s-%(prop:release)s.tar.gz"),
                util.Interpolate("--remote-file=uploads/rac-gui/rac-gui-%(prop:version)s-%(prop:release)s.tar.gz")]
        )
)

We're done with RPM. Now let's describe the process of building the DEB package. Since the packaging processes for different systems are independent of each other, many steps will be repeated.


rac_gui_build_DEB = util.BuildFactory()

rac_gui_build_DEB.addStep(steps.Git(
       repourl = 'https://bitbucket.org/svk28/rac-gui.git',
       haltOnFailure = True,
       submodules = True,
       mode='full',
       workdir='build',
       progress = True)
)

# Adding version definition from the main file
rac_gui_build_DEB.addStep(
       steps.SetPropertyFromCommand(
       command="grep version rac_gui.tcl | grep -oE 'b[0-9]{1,2}.[0-9]{1,2}.[0-9]{1,2}b'", property="version"
       )
)

# Adding release definition from the main file
rac_gui_build_DEB.addStep(
       steps.SetPropertyFromCommand(
       command="grep release rac_gui.tcl | grep -oE 'b[0-9]{1,3}b'", property="release"
       )
)

# Rename the executable file
    rac_gui_build_DEB.addStep(steps.ShellCommand(
       command=["mv", "rac_gui.tcl", "racgui"]))

For the RPM package, some of the following procedures are handled by rpm during the build and are described inside the spec file; for Debian, this needs to be done here:

# ПомСняСм ΠΏΡƒΡ‚ΠΈ ΠΊ Π±ΠΈΠ±Π»ΠΈΠΎΡ‚Π΅ΠΊΠ°ΠΌ

rac_gui_build_DEB.addStep(
       steps.FileUpload(
       workersrc=util.Interpolate("../rac-gui_%(prop:version)s-%(prop:release)s_amd64.deb"),
           masterdest=util.Interpolate("/home/buildbot/builds/rac-gui_%(prop:version)s-%(prop:release)s_amd64.deb")
       )
)
rac_gui_build_DEB.addStep(
        steps.MasterShellCommand(
            command=["/usr/local/bin/deploy-ftp.tcl",
             util.Interpolate("--local-file=/home/buildbot/builds/rac-gui_%(prop:version)s-%(prop:release)s_amd64.deb"),
             util.Interpolate("--remote-file=uploads/rac-gui/rac-gui_%(prop:version)s-%(prop:release)s_amd64.deb")]
        )
)

And that's it for DEB, now onto Windows!

rac_gui_build_WIN = util.BuildFactory()

rac_gui_build_WIN.addStep(steps.Git(
       repourl = 'https://bitbucket.org/svk28/rac-gui.git',
       haltOnFailure = True,
       submodules = True,
       mode='full',
       workdir='build',
       progress = True)
)

Since Windows does not natively have grep and sed (or does it?), we'll be using PowerShell.

The setup process is now complete. You can check the current status through the web interface, where you can also see build errors, kick a stuck process if something went wrong, etc.

Right after launching our workers, you can view them via the menu "Builds" -> "Workers".

Buildbot in the examples.

After the first build process is completed (i.e., changes in the Git repository), the status of the processes will appear on the front page.

Buildbot in the examples.

If you click on the desired row, a page will open showing the current status of this process, including what is occurring, what errors there are, etc.

Buildbot in the examples.

You can get the entire master config here.
