CI Setup

Pipeline

  1. unit-tests: fast jobs for fast feedback (linting, etc...)
  2. deploy-part1: small number of jobs to test if the PR works with default settings
  3. deploy-part2: slow jobs testing different platforms, OS, settings, CNI, etc...
  4. deploy-part3: very slow jobs (upgrades, etc...)

Runners

Kubespray has 3 types of GitLab runners:

  • packet runners: used for E2E jobs (usually long)
  • light runners: used for short lived jobs
  • auto scaling runners: used for on-demand resources, see GitLab docs for more info

Vagrant

Vagrant jobs are using the quay.io/kubespray/vagrant docker image with /var/run/libvirt/libvirt-sock exposed from the host, allowing the container to boot VMs on the host.

CI Variables

In CI we have a set of overrides we use to ensure greater success of our CI jobs and avoid throttling by various APIs we depend on. See:
