Which pipelines each component runs on¶

Every component carries its own rules:. Nothing here is inherited from your pipeline, and including a component does not mean its job appears on every pipeline — most of them are deliberately silent on most pipeline types. This page is the lookup table for which.

Two things decide whether a job appears:

The component's own rules:, fixed in the template.
Your workflow: rules, which decide whether the pipeline exists at all. A component cannot run on a pipeline your workflow: never created.

The trigger matrix¶

Columns are GitLab pipeline sources. MR is merge_request_event; branch is a push to a non-default branch with no merge-request pipeline; default is a push to $CI_DEFAULT_BRANCH; tag is a tag push; schedule is a scheduled pipeline.

✅ runs · — no rule matches, so no job is created · ❌ an explicit when: never suppresses it

Notes on individual rows:

hugo-build's MR and branch runs come from mr_gate, which defaults to true. That rule carries no pipeline-source condition, so the build gate fires on a merge request and on a plain branch push whenever a changes path was touched. Setting mr_gate: false (the loose direct-to-main mode) turns both columns into —.
tofu-apply and tofu-deploy-generate are one job, not two. plan_source and mode select a hidden job that carries the rules:, so choosing the mode chooses the trigger. Two rows, one job.
renovate-group also runs off-schedule when $RENOVATE_TARGET_FILTER is set — the manual-run escape hatch for a single repo, on any pipeline its if input matches.
The default-branch column assumes your workflow: creates a default-branch pipeline. Many repositories only run one so that a release driver can maintain its Release MR.

Why almost no component runs on a scheduled pipeline¶

Every other component's first rule is if: $CI_PIPELINE_SOURCE == "schedule" → when: never, unconditionally, before anything a consumer can influence.

A scheduled pipeline exists to do one job — run Renovate, or rebuild a time-sensitive site. Without the guard, every gate in the repository would also fire on that schedule: a full lint/test/security fan-out, nightly, on a commit nobody pushed and nobody is waiting on. On a fixed-concurrency self-hosted runner that is capacity taken from pipelines somebody is waiting on.

The guard is first and unconditional so that widening a component's if input cannot pull the job back onto the schedule. renovate-self, renovate-group, renovate-merge and release-train have no guard because the schedule is the only place they are meant to run; hugo-pages deliberately runs on a schedule so future-dated content publishes without a push.

release-train is the exception among the four: a scheduled run only ever plans, and it refuses to execute on a schedule even when explicitly told to, because cutting releases is a per-train decision and never a standing one.

Why change-detection never applies to a tag or a schedule¶

rules:changes compares a diff, and a tag or scheduled pipeline has no meaningful diff to compare — GitLab treats the filter as always-true there. Filtering a release job on something that is always true is not a filter, and filtering it on something unreliable would occasionally skip a release. So changes: is attached only to merge-request rules (and, for the static-site components, to the branch rule that feeds a deploy).

The reasoning is in Explanation: change-detection; the recipe is Add change-detection to a gate.

Which components let you change when they run¶

Only some. A component with an if input exposes its trigger condition; a component without one has its trigger welded to the job it does, because the trigger and the work are one decision.

Has an `if` input (overridable)	No `if` input (fixed trigger)
`go-lint`, `go-test`, `go-security`	all eight `tofu-*` components
`rust-lint`, `rust-test`, `rust-docs`, `rust-security`	`goreleaser`
`svelte-build`, `svelte-lint`, `svelte-test`, `svelte-security`	`zensical-pages`, `hugo-pages`
`skill-security`
`release-plz`, `releaser-pleaser`
`renovate-self`, `renovate-group`, `renovate-merge`
`release-train`, `release-stamp`, `discord-release`

The fixed ones are fixed for a reason worth knowing:

tofu-plan / tofu-apply authenticate by OIDC, and the AWS trust policy only accepts subjects from the refs it was written for. A job moved to a ref the trust policy does not name does not run a wrong plan — it fails at assume-role.
tofu-apply's trigger is coupled to plan_source: needs: and rules: both live in a per-mode hidden job the component extends, so choosing job or ref is choosing the trigger.
goreleaser and tofu-module-publish publish artefacts. Their tag match is the release gate; making it overridable would make it possible to publish from a branch.

Widening a trigger you can widen still cannot reach a scheduled pipeline — see above.

Why the Tofu gates run on branch pushes and the Go, Rust and Svelte gates do not¶

This is a real difference, not a documentation slip. tofu-lint, tofu-security, tofu-validate and the zensical-pages build job have no if: on their run rule at all — they exclude schedules and tags and then run on whatever is left, which includes a plain branch push. The Go, Rust and Svelte gates default their if input to $CI_PIPELINE_SOURCE == "merge_request_event" and so run on merge requests only.

On a project with the usual workflow: dedup rule this is invisible, because no branch pipeline is created once a merge request is open:

workflow:
  rules:
    - if: '$CI_PIPELINE_SOURCE == "merge_request_event"'
    - if: '$CI_COMMIT_BRANCH && $CI_OPEN_MERGE_REQUESTS'
      when: never
    - if: '$CI_COMMIT_TAG'
    - if: '$CI_COMMIT_BRANCH == $CI_DEFAULT_BRANCH'
    - if: '$CI_PIPELINE_SOURCE == "schedule"'

Without that dedup rule, a push to a branch that already has an open merge request runs the Tofu gates twice — once on the branch pipeline, once on the merge-request pipeline. Keep the $CI_COMMIT_BRANCH guard on the never rule: keying it on $CI_PIPELINE_SOURCE == "push" also matches a tag push and suppresses the entire tag pipeline, which is how a release silently stops publishing.

What "no rule matched" looks like¶

A component whose rules do not match produces no job. There is no skipped job, no grey icon, no entry in the pipeline graph — the job simply is not there. The pipeline goes green having run nothing.

That is the failure mode to expect when a component appears to have been ignored, and it is the first thing to check: not "why did my job fail" but "is my job in the pipeline at all". See Diagnose a job that did not run.
