Buildbot master configuration for buildbot.python.org.
The production server uses /etc/buildbot/settings.yaml configuration file which contains secrets like the IRC nickname password.
Run locally:
make git-update-requirements
Create a PR. Merge the PR. The new venv will be recreated automatically on the server.
If something goes wrong, commands to recreate the venv manually on the server:
make stop-master
git pull
mv venv old-venv
make venv
make start-master
# then you may watch logs in realtime:
# tail -F master/twistd.log
Upgrading buildbot sometimes requires to run the command:
./venv/bin/buildbot upgrade-master /data/buildbot/master
Make sure that the server is running, and then remove the old virtual environment:
rm -rf old-venv
The buildbot master is hosted on the PSF Infrastructure and is managed via salt.
psycopg2 also requires libpq-dev:
sudo apt-get install libpq-dev
- Backend host address is
buildbot.nyc1.psf.io. - The host is behind the PSF HaProxy cluster which is CNAMEd by
buildbot.python.org. - Database is hosted on a managed Postgres cluster, including backups.
- Remote backups of
/etc/buildbot/settings.yamlare taken hourly and retained for 90 days. - No other state for the buildbot host is backed up!
Configurations from this repository are applied from the master branch on
a */15 cron interval using the update-master target in Makefile.
Python 3.9 is installed manually using pyenv (which was also installed
manually). Commands to install Python 3.9:
pyenv update
pyenv install 3.9.1
pyenv global 3.8.1 3.9.1
The list of workers is stored in /etc/buildbot/settings.yaml on the server.
A worker password should be made of 14 characters (a-z, A-Z, 0-9 and special
characters), for example using KeePassX.
- Generate a password
- Add the password in
/etc/buildbot/settings.yaml - Restart the buildbot server:
make restart-master
