GitHub Actions 🎬

This page catalogs every GitHub Actions workflow defined under the workflows directory. It lists each workflow together with a short description, its triggers, and the inputs it accepts.

For the CI flow (orchestrator stages, gates, fork-PR handling) see pipeline.md. For the repository variables that control CI behaviour see configuration.md. For the naming and shell-extraction conventions that every workflow file MUST follow see workflow.md. For the branch-prefix scopes referenced by the PR entry workflow see branch.md. For the mirror architecture referenced by the image workflows see mirror.md.

What GitHub Actions are 📘

GitHub Actions is GitHub's built-in CI/CD system. Each YAML file under .github/workflows/ is one workflow; a workflow contains one or more jobs, and each job runs a sequence of steps on a hosted or self-hosted runner. Workflows are started by triggers declared in the on: section. The most common triggers in this repository are:

• push: fires when commits land on a branch.
• pull_request / pull_request_target: fires on PR lifecycle events (opened, synchronize, reopened, ready_for_review, closed, converted_to_draft). The _target variant runs with the base-branch secrets and is used to grant fork PRs controlled access to privileged steps.
• schedule: cron-based periodic runs (UTC).
• workflow_dispatch: manual run from the GitHub UI or gh workflow run, optionally with inputs.
• workflow_call: the workflow is a reusable workflow and is only started by another workflow that calls it via uses:.
• delete: fires when a branch or tag is deleted.

Workflows communicate through inputs (on workflow_call / workflow_dispatch), outputs, concurrency groups (which cancel or serialize runs with the same group key), and the GITHUB_TOKEN / repository secrets and variables. The entry points of this repository (entry-*.yml) translate external triggers into a call to the central ci-orchestrator.yml. Most other workflows are reusable building blocks invoked from the orchestrator.

Workflow catalog 📚

Trigger column legend: auto = fires automatically (push, pull_request, schedule, delete); manual = workflow_dispatch; reusable = workflow_call. Multiple values mean the workflow accepts any of them.

Entry points 🚪

Workflow	Description	Trigger	Inputs
entry-pull-request-change.yml: ⚡ CI: Pull Request	Detects PR scope from changed files + branch prefix, then conditionally calls the orchestrator.	auto (pull_request, pull_request_target: opened, synchronize, reopened, ready_for_review)	none
entry-push-latest.yml: ⚡ CI: Push	Runs the orchestrator on pushes to main, feature/**, hotfix/**, fix/**, chore/**, alert-autofix-*; on tagged main it also calls release-version.yml. Respects the CI_CANCEL_IN_PROGRESS and CI_RUN_ON_MAIN repository variables, see configuration.md.	auto (push)	none
entry-manual.yml: ⚡ CI: Manual	Manual dispatch of the full orchestrator for a chosen distro set and app whitelist. The whitelist input accepts the __ALL__ sentinel for forced full deploy; see the "Diff-driven app selection" subsection in pipeline.md.	manual	distros (default debian), whitelist (optional; __ALL__ forces full deploy, empty triggers diff derivation, any other value is verbatim)
entry-pull-request-cancel.yml: 🚫 Cancel: PR Runs on Close	Cancels active workflow runs for a PR when it is closed or converted to draft.	auto (pull_request_target: closed, converted_to_draft)	none
delete-branch.yml: 🚫 Cancel: Runs on Branch Delete	Enters the push-entry concurrency group for the deleted branch so that any in-flight run on it is cancelled; a fallback step cancels remaining runs via the API.	auto (delete)	none

Orchestration 🎵

Workflow	Description	Trigger	Inputs
ci-orchestrator.yml: 🎵 CI: Orchestrator	Central coordinator. Runs fork-prereq wait, security, linting, CI image build, code tests, code-quality gate, DNS tests, mirror, deploy tests, install tests, development-environment test, final done gate.	reusable	distros (default arch debian ubuntu fedora centos), whitelist (optional), image_wait_attempts (default 1980), image_wait_sleep_seconds (default 10)

Security and linting 🛡️🔍

Workflow	Description	Trigger	Inputs
security-codeql.yml: 🔒 Scan: CodeQL (Advanced)	CodeQL static analysis. Invoked by ci-orchestrator.yml so every CI run produces a single scan; additionally runs on a weekly cron so coverage does not drop when no pushes land on main. See pipeline.md for the gating behaviour.	reusable, auto (schedule: weekly Mon 00:00 UTC)	none
lint-ansible.yml: 🔍 Lint: Ansible	Runs make lint-ansible.	reusable	none
lint-docker.yml: 🔍 Lint: Dockerfiles	hadolint on Dockerfile with SARIF upload.	reusable	none
lint-python.yml: 🔍 Lint: Python	ruff over the Python sources.	reusable	none
lint-shell.yml: 🔍 Lint: Shell Scripts	shellcheck over every *.sh file.	reusable	none

CI images 🐳

Workflow	Description	Trigger	Inputs
images-build-ci.yml: 🖼️ Build: CI Images (all distros)	Builds the per-distro CI base images consumed by all test jobs.	reusable	distros (required), checkout_ref (optional), image_tag (default ci-${github.sha}), concurrency_channel (default default)
images-cleanup-ci.yml: 🧹 Images: Cleanup CI (GHCR)	Deletes CI images from GHCR older than N days.	auto (schedule: weekly Mon 00:00 UTC), manual	days (default 7)

Image mirroring 🪞

Workflow	Description	Trigger	Inputs
images-mirror-missing.yml: 🪞 Mirror: Docker Hub → GHCR (only missing)	Mirrors only the upstream images that are not yet in GHCR. Called from the orchestrator before deploy tests.	reusable	ghcr_namespace, ghcr_prefix (default mirror), repo_root (default .), source_repository, source_ref, plus throttling knobs
images-mirror-all.yml: 🪞 Mirror: Docker Hub → GHCR	Full nightly mirror of every referenced upstream image into GHCR.	auto (schedule: daily 00:00 UTC), manual	ghcr_namespace, ghcr_prefix (default mirror), repo_root (default .), images_per_hour (throttle)
images-mirror-cleanup.yml: 🧹 Images: Cleanup GHCR (Private)	Deletes GHCR mirror packages by prefix and visibility. Supports dry_run.	manual	ghcr_namespace, ghcr_prefix (default mirror), visibility (private/public/internal, default private), dry_run

Code tests 🧪

Workflow	Description	Trigger	Inputs
test-code-unit.yml: 🧪 Test: Code (Units)	Runs make test-unit in the CI container.	reusable	none
test-code-integration.yml: 🧪 Test: Code (Integration)	Runs make test-integration in the CI container.	reusable	none

Infrastructure tests 🌐📦💻📥

Workflow	Description	Trigger	Inputs
test-dns.yml: 💬 Test: DNS	Validates DNS resolution across target distributions.	reusable, manual	distros (required on call; default debian on manual)
test-deploy-compose.yml: 📦 Test: Deploy (compose)	Deploy test (compose mode) across all deployment types (INFINITO_DISCOVER_ALL; lifecycle-filtered to alpha beta rc stable, so server/universal/workstation scopes but not just web-*). When whitelist is empty, the discover job derives one from the branch's diff vs origin/main; see the "Diff-driven app selection" subsection in pipeline.md.	reusable	distros (required), whitelist (optional; explicit value wins over diff)
test-deploy-swarm.yml: 🐝 Test: Deploy (swarm)	Deploy test (swarm mode) across the full application matrix; each app gets a simulated 3-node DinD cluster with an NFS server, then a drain/reschedule state-survival assertion. Same diff-driven whitelist resolution as test-deploy-compose.yml.	reusable, manual	whitelist (optional; explicit value wins over diff)
test-install-make.yml: 📥 Test: Install Make	Validates the make install entry points.	reusable	none
test-install-pkgmgr.yml: 📥 Test: Install Package Manager	Validates installation via the upstream package manager.	reusable	none

Release and maintenance 🚀🔄

Workflow	Description	Trigger	Inputs
release-version.yml: 🚀 Release: Version Logic	Releases a specific version tag (build + publish). Called from entry-push-latest.yml on tagged pushes.	reusable, manual	tag (required, e.g. v1.2.3)

update.yml: 🔄 Update: Versions	Updates Docker image versions and other pinned dependencies; opens an update PR via a GitHub App installation token so PR-lifecycle events fire on the resulting PR. Both jobs are gated behind the CI_ENABLE_AUTO_UPDATES repository variable, see configuration.md. Requires the BOT_APP_CLIENT_ID and BOT_APP_PRIVATE_KEY repository secrets, see secrets.md.	auto (push to main, schedule: daily 00:30 UTC), manual	none
dependabot-close.yml: 🚫 Dependabot: Close while auto-updates disabled	Auto-closes Dependabot PRs while CI_ENABLE_AUTO_UPDATES is not set to true, so Dependabot honours the same gate as the workflow-driven update jobs. See configuration.md.	auto (pull_request_target: opened, reopened)	none

Changing workflows ✍️

Before adding or editing a workflow file:

1. Follow the naming schema and shell-extraction rules in workflow.md.
2. If the change affects the CI flow (stages, gates, order), also update pipeline.md.
3. If the change adds or removes a repository variable, also update configuration.md.
4. Update the relevant row in this page so the catalog stays accurate.
