It explains the CI environment, project setup, documentation publishing, tools, and response to infrastructure outages; it is not a single software product.
What the lf-releng-docs site covers
The master documentation site brings together procedures and technical references for teams working with LF CI services. Its guides cover the CI environment and best practices, Ansible, Git, Gerrit, GPG2, Jenkins, Jenkins Sandbox, Jenkins Build Failure Analyzer, Nexus 2 and 3, MeetBot, SSH, and project documentation. It also links to self-service procedures for project creation, committer management, and GitHub Copilot Enterprise access for LF project maintainers.

The site points to tools including common-packer, lfdocs-conf, lftools, global-jjb, pipelines, and gerrit-to-platform. The infrastructure guide is organized around inventory and escalation, new-infrastructure bootstrap, Gerrit, Jenkins, JIRA, Nexus, OpenStack management, and GitHub setup. In practical terms, use the landing page to find the relevant operational guide, then follow the service-specific procedure rather than treating the documentation as a standalone application.

LF says projects generally receive a similar CI setup unless there is a reason to deviate. In the documented design, CI systems and artifact storage sit in a DMZ cloud where project communities can interact with them. Private, dynamic build instances connect to DMZ resources and external internet services, but are not given access to deeper LF networks. Services that do not need to be colocated with CI may be hosted in another cloud or provider to reduce the impact of a security issue affecting repository hosting.

Project access can also change over time. During pre-formation, access is restricted; after formation, hosted services become public and inventories are updated. The environment guide says seed code should meet applicable intellectual-property and licensing requirements and be introduced as a squash commit with a Developer’s Certificate of Origin sign-off.
How project creation with INFO.yaml works
Project creation is initiated through a change to the releng/info-master repository. A maintainer finds the appropriate path, creates the project directory, and adds an INFO.yaml file with project and committer details. After checking and signing off the change, the maintainer submits it for review. Approval and merge trigger automation that creates the Gerrit project and related resources.
- Locate the project path: find the correct location in
releng/info-master. - Add project metadata: create the directory and complete its
INFO.yamlwith the required project and committer information. - Submit a signed change: check the file, commit with sign-off, and send the change for review.
- Complete CI configuration: after the INFO.yaml change is merged, update project credentials as needed. In the project’s
ci-managementrepository, maintainers create Maven settings and credential mappings so Jenkins can deploy artifacts and container images to Nexus or Nexus3.
The merge is the automation trigger for project and related-resource creation; it does not eliminate the follow-on Jenkins credential and deployment configuration.
How project documentation is built and published
LF recommends writing project documentation in reStructuredText and building it with Sphinx. The toolchain separates authoring, common configuration, and CI publishing:
- Authoring: reStructuredText provides the source format.
- Build: Sphinx processes the documentation.
- Shared dependencies and configuration:
lfdocs-confsupplies common documentation dependencies and settings. - CI publication:
global-jjbprovides job templates that build and publish the documentation.
This means teams can use LF’s shared configuration and Jenkins job templates instead of inventing a separate publication workflow for each project.

These services are considered critical because they support the basic development loop: Gerrit provides code access and review, Jenkins runs builds, and Nexus stores or serves artifacts. A project’s own code or compilation failure is not, by itself, an infrastructure emergency. Treat an incident as an infrastructure issue when a service outage prevents developers from fetching code, retrieving artifacts, or running builds.
Rank #4
- Investigate the failure and fix it locally if possible.
- If it appears to be a service or infrastructure problem, contact the LF IT infrastructure channel when needed.
- For an emergency escalation, call the emergency line and clearly identify the project and the failed service.
The documentation presents this as an escalation path, not a substitute for diagnosing ordinary project build errors.
