Jenkins Infra

This repository hosts the Puppet code for the Jenkins project's own infrastructure.

Structure

See the Jenkins infrastructure project for overview of the project's infrastructure and the services being managed by this repository. A non exhaustive list of services is available here.

Implementation notes

The services are managed r10k and Puppet, configuration files are available inside this repository.
There are multiple types of service deployments:
- The majority of services run as containers inside Kubernetes, and are NOT managed here (ref. jenkins-infra/charts)
- Some services like ci.jenkins.io run inside virtual machines provisioned in cloud providers
- the other services are running on bare metal machines provided by sponsors
There are Puppet templates for all services. Configuration options are defined by Hiera and stored in hieradata. See hieradata/common.yaml for the most of the settings.
Not all services are fully configured with Configuration-as-Code. For example, Jenkins controllers (jenkinscontroller profile) rely on configurations being supplied from Jenkins home directories.

Containerized services

All containerized services are stored in separate repositories (Plugin Site, IRC Bot, etc.). They have their own release cycles and maintainers. This repo just manages and configures the deployments.

See this page for service repository links.
Service images are hosted inside the jenkinsciinfra DockerHub account.
Usually there is a Continuous Delivery pipeline configured for services inside their repositories.
Image versions are defined in the hieradata/common.yaml file by the *:image_tag variables. Services can be updated by submitting a pull request with the version update.

Editing secrets

All the secrets are encrypted within the repository using eyaml. in order to view or edit them:

Follow instructions in (private repository) https://github.com/jenkins-infra/jenkins-keys
Use the command bundle exec eyaml edit <filename> such as bundle exec eyaml edit ./hieradata/common.yaml

Local development

Pre-requisites for Local Development

Ruby 2.6.x is required.
- Please note that Ruby 2.7.x and 3.x have never been tested.
Bundler 1.17.x is required with the command line bundle installed and present in your PATH.
- Please note that Bundler 2.x had never been tested
A bash-compliant shell is required.
- sh has never been tested, neither Windows Cygwin Shell (but WSL is ok).
The command line yq in version 4.x is needed

You can always check the Docker image that ci.jenkins.io uses to run the test harness for this project at https://github.com/jenkins-infra/docker-inbound-agents/blob/main/ruby/Dockerfile (Jenkins agent labelled with ruby).

Install Local Dependencies

Run the script ./scripts/setupgems.sh to ensure that all the local dependencies are ready for local development, including:

Ruby Gems managed by bundler (through Gemfile and Gemfile.lock) to ensure development tools are available through bundle exec <tool> commands
Puppet modules retrieved from ./Puppetfile and installed to ./modules
Unit Tests fixtures generated from ./Puppetfile into .fixtures.yml but also other locations in ./spec/

Vagrant-based testing

Running Acceptance Tests

TL;DR: As for today, there are no automated acceptance tests. Contributions are welcome.

A long time ago, this repository used serverspec for on-machine acceptance testing. Combined with Vagrant, it allowed to execute acceptance tests per-role.

But this serverspec with Vagrant uses deprecated (and not maintained anymore) components.

Proposal for the future:

Switch to Goss as it can also be used for Docker with the dgoss wrapper and provides automatic adding tests
ServerSpec V2 executed through vagrant ssh (but requires updating ruby dependencies + find a way to run serverspec within the VM instead of outside)

Pre-requisites for Vagrant

Make sure that you have set up all the Pre-requisites for local development above
Install Vagrant version 2.x.
Install Docker
- Docker Desktop is recommended but any other Docker Engine installation should work.
- Only Linux containers are supported, with Cgroups v2. (CGroups v1 might work).
- The command line docker must be present in your PATH.
- You must be able to share a local directory and to use the flag --privileged.
Run the ./scripts/vagrant-bootstrap.sh script to prepare your local environment.

To launch a test instance, vagrant up ROLE where ROLE is one of the defined roles in "dist/role/manifests/".

Ex: vagrant up jenkins::controller

All machines should have the same base Ubuntu version, however we can have edge cases. As such, you can specify the Ubuntu version through the environment variable UBUNTU_VERSION.

Ex: UBUNTU_VERSION=18.04 vagrant up pkg

NOTE: there are a LOT of corner cases and a generic code (Dockerfile and Vagrantfile) would only mean writing tons of hashmaps to cover all cases. Work on using another tool such as molecule instead if you want to spend time fixing this.

Note: for this role, there may be the following error message because plugins installation needs a running Jenkins instance while it's not quite ready when it happens:

Error: /Stage[main]/Profile::Jenkinscontroller/Exec[perform-jcasc-reload]: Failed to call refresh: '/usr/bin/curl -XPOST --silent --show-error http://127.0.0.1:8080/reload-configuration-as-code/?casc-reload-token=SuperSecretThatShouldBeEncryptedInProduction' returned 7 instead of one of [0]

You can safely ignore it.

You can re-run puppet and execute tests with vagrant provision ROLE repeatedly while the VM is up and running. When it's all done, remove the instance the instance via vagrant destroy ROLE.

Branching model

The default branch of this repository is production which is where pull requests should be applied to by default.


+----------------+
| pull-request-1 |
+-----------x----+
             \
              \ (review and merge, runs tests)
production     \
|---------------o--x--x--x---------------->

When a infra project team member is happy with the code in your pull request, they can merge it to production, which will be automatically deployed to production hosts.

Installing agents

For installing agents refer to the installing agents section of the PuppetLabs documentation.

Adding a new branch/environment

"Dynamic environments" are in a bit of flux for the current version (3.7) of Puppet Enterprise that we're using. An unfortunate side-effect of this is that creating a branch in this repository is not sufficient to create a dynamic environment that can be used via the Puppet master.

The enable an environment, add a file on the Puppet master: /etc/puppetlabs/puppet/environments/my-environment-here/environment.conf with the following:

modulepath = ./dist:./modules:/opt/puppet/share/puppet/modules
manifest = ./manifests/site.pp
