docs(api): document that terminationGracePeriodSeconds does nothing - #72
Merged

Conversation
Upstream removed the key at the v17.0.0 major boundary. The runner decodes with toml.DecodeFile and never inspects MetaData.Undecoded(), so a value set here is accepted by admission, rendered into config.toml, and then dropped with no error, no warning and no log line. The mitigation the issue credits does not exist on any user-facing surface. controller-gen only turns Go doc comments into the CRD description; the go-flags `description:` tag is invisible, so the deprecation text this field has carried since v16.11.0 never reached kubectl explain. Same finding as #71. All three fields here gain their first real description. Both replacements carried the same fossil, "Ignored if KUBERNETES_TERMINATIONGRACEPERIODSECONDS is specified", pointing at a key that no longer exists. Dropped from the tags rather than contradicted in a comment next to them. The v17.0.0 removal also moved a default. At v16.11.0 GetPodTerminationGracePeriodSeconds returned 0 when both keys were unset, which upstream commented as deliberate ("terminate immediately"). That getter went with the field, so the executor now passes the raw pointer to the pod spec and unset means Kubernetes' 30s. A runner upgraded across the boundary waits 30s where it used to exit at once, which is the fact a reader of pod_termination_grace_period_seconds most needs. Not removing the field. kubectl has defaulted to fieldValidation=Strict since 1.25, so dropping it from the CRD fails `kubectl apply` for any manifest that still sets it. That belongs in a release documenting the break, so the key is excluded from the release watcher's stale report instead, which #70 made bidirectional. The exclusion is counted in every release issue body and the watcher flags it as unused once the field goes, so it cannot rot silently.

The description read "kill signal.DEPRECATED:", running two sentences together. Tidied while the neighbouring tags are being edited in this branch anyway. Note this is cosmetic only. CodeRabbit flagged it as breaking generated help text, which does not apply here: nothing in the operator parses go-flags tags and controller-gen ignores them, so the string never reaches a user. Regenerating the CRDs after this change produces no diff, which is the same point the rest of the branch makes. Refs: #62 Signed-off-by: Alexander Chernov <alexander@chernov.it>

terminationGracePeriodSecondshas had no effect since gitlab-runner v17.0.0 removed the key, but the CRD still advertises it and the runner drops it silently, so a user gets no error and no grace-period behaviour. This adds the description that says so.Two things changed what the fix had to do. The mitigation #62 credits does not exist on any user-facing surface: controller-gen only turns Go doc comments into the CRD
description, so the deprecation text in the go-flags tag has never reachedkubectl explain, same as #71. And the v17.0.0 removal moved a default, sinceGetPodTerminationGracePeriodSecondsused to return 0 ("terminate immediately") when both keys were unset and went away with the field, so unset now means Kubernetes' 30s. A runner upgraded across that boundary waits 30s where it used to exit at once, which is the factpod_termination_grace_period_secondsmost needed and nothing was saying. Both replacements also stop pointing at the dead key.Not removing the field: kubectl has defaulted to
fieldValidation=Strictsince 1.25, so that failskubectl applyfor anyone still setting it and belongs in a release documenting the break. It is excluded from the release watcher's stale report instead, counted in every release issue body and flagged as unused once the field goes. #62 stays open to track the removal.Upstream claims checked against v16.11.0, v17.0.0 and v19.2.2.
