Niels de Vos ffb4634ba5 ci: pass REBASE=1 to have commitlint rebase the branch 
When Mergify adds a merge commit to the branch that is being tested with
commitlint, the tool tries to detect the most recent changes based on
the newly merged commit. This is for most PRs the master branch, and
that contains incorrect commit messages in the history. Because of this,
commitlint will fail.

By adding an option (REBASE=1) to the commitlint make target, CI jobs
can request a rebase so that the history of the PR becomes linear again
and commitlint should be able to detect only the new commits.

Continuous Integration Jobs for the CentOS CI

  • dedicated Jenkins instance for Ceph-CSI
  • Jenkins is hosted on OpenShift in the CentOS CI
  • scripts and Jenkins jobs are hosted in the Ceph-CSI repository (ci/centos branch)
  • a Jenkins Pipeline is used to reserve bare metal system(s), and run jobs on those systems

Repository/Branch Structure

This is the ci/centos branch, where all the scripts for the Jenkins jobs are maintained. The tests that are executed by the jobs are part of the normal projects branches.

As an example, the containerized-tests Jenkins job consists out of the following files:

  • jobs/containerized-tests.yaml is a Jenkins Job Builder configuration that describes the events when the job should get run and fetches the .groovy file from the git repository/branch

  • containerized-tests.groovy is the Jenkins Pipeline that contains the stages for the Jenkins Job itself. In order to work with the bare-metal machines from the CentOS CI, it executes the following stages:

    1. dynamically allocate a Jenkins Slave (node('cico-workspace')) with tools and configuration to request a bare-metal machine
    2. checkout the centos/ci branch of the repository, which contains scripts for provisioning and preparing the environment for running tests
    3. reserve a bare-metal machine with cico (configured on the Jenkins Slave)
    4. provision the reserved bare-metal machine with additional tools and dependencies to run the test (see prepare.sh below)
    5. run make containerized-tests and make containerized-build in parallel
    6. as final step, return the bare-metal machine to the CentOS CI for other users (it will be re-installed with a minimal CentOS environment again)

  • prepare.sh installs dependencies for the test, and checks out the git repository and branch (or Pull Request) that contains the commits to be tested (and the test itself)

Deploying the Jenkins Jobs

The Jenkins Jobs are described in Jenkins Job Builder configuration files and Jenkins Pipelines. These need to be imported in the Jenkins instance before they can be run. Importing is done with the jenkins-jobs command, which runs in a jjb container. To build the container, and provide the configuration for Jenkins Job Builder, see the documentation in the deploy/ directory.
