YunoHost-CI: Gitlab runner for YunoHost Core

Introduction

yunohost-ci is a custom executor for Gitlab Runner.

It uses LXD/LXC environment to run tests on YunoHost Core. Tests must be written in file .gitlab-ci.yml on each YunoHost Core repository to test.

Setup YunoHost-CI

First you need to install the system dependencies.

yunohost-ci essentially requires Git and the LXD/LXC ecosystem.

For Gitlab Runner, you can find doc here. On Debian-based system, you can add GitLab’s official repository:

curl -L https://packages.gitlab.com/install/repositories/runner/gitlab-runner/script.deb.sh | sudo bash

Then install Gitlab Runner (min version: 12.1):

sudo apt-get install gitlab-runner

Then follow this doc to install incus on your system: https://linuxcontainers.org/incus/docs/main/installing/#install-incus-from-a-package

Then you shall initialize incus which will ask you several questions. Usually answering the default (just pressing enter) to all questions is fine. (doc)

sudo incus admin init

Register YunoHost-CI

To use this runner, you must register the Gitlab Runner that you just installed (you can register in on several projects, or on the group that contains all projects). But, you have to disable the shared runner to only use this runner and not "Official" that is using a docker executor.

You can follow this official doc to register it. The only think to change is the point number 6, where you have to choose custom.

After that, clone this repo where you want, and be sure that scripts base.sh cleanup.sh prepare.sh and run.sh have the execution permission.

Finally, edit the file /etc/gitlab-runner/config.toml to add builds_dir, cache_dir, and all the [runners.custom] section. Your file should looks like this:

concurrent = 1
check_interval = 0

[session_server]
  session_timeout = 1800

[[runners]]
  name = "yunohost-ci"
  url = "https://gitlab.com/" # Gitlab URL
  token = "[SECRET-TOKEN]" # Very private token
  executor = "custom"
  builds_dir = "/builds" # Will be created if doesn't exist
  cache_dir = "/cache" # Will be created if doesn't exist
  [runners.custom]
    prepare_exec = "/opt/yunohost-ci/prepare.sh" # Path to a bash script to create lxd container and download dependencies.
    run_exec = "/opt/yunohost-ci/run.sh" # Path to a bash script to run script inside the container.
    cleanup_exec = "/opt/yunohost-ci/cleanup.sh" # Path to bash script to delete container.
  [runners.custom_build_dir]
    enabled = true

Using images

Use the field image to switch between before-install or after-install (after-install by default) for example:

  • image: after-install to use the image after the postinstall of Yunohost
  • image: before-install to use the image before the installation of YunoHost

TODO

  • Support more YunoHost Core projects (for now only yunohost is supported, not moulinette...)
  • Git pull this repo before running tests to keep these files up-to-date.
