LTTng configuration for Jenkins

This repository holds the configuration of the LTTng Jenkins jobs. It is meant to be used with Jenkins Job Builder from the OpenStack Foundation.

The dependencies can be installed in a dedicated Python virtual environment using Poetry:

$ poetry install

You can then run commands from the virtual environments by prepending poetry run to them:

$ poetry run jenkins-jobs --version
Jenkins Job Builder version: 6.4.2

or by spawning a shell:

$ poetry shell
Spawning shell within /home/user/.cache/pypoetry/virtualenvs/lttng-ci-qYTnEJGo-py3.12
(lttng-ci-py3.12) $ jenkins-jobs --version
Jenkins Job Builder version: 6.4.2

Install pre-commit hooks with:

$ pre-commit install
