Every claimed collection got its own updater service account, and with it two more bindings
in the project IAM policy. At the 115 collections the migration will onboard that is 230
bindings and roughly 63KB, which alone puts the policy over its ~67KB cap.
Almost none of them are wanted. Group members can already write to every collection their
group owns, through the group's own updater binding; the service account exists for
automation that cannot authenticate as a group member. Four collections have one today.
A group now names the collections it wants one for:
test-platform-gsm-secrets-owners:
secret_collections:
- psalajova-first-secret
- test-platform-infra
updater_service_accounts:
- psalajova-first-secret
- test-platform-infra
Collections not listed still get their index secret and are still covered by their group's
bindings; they just have no service account, no SA secret and no service-account-scoped
bindings. The code that creates all of that is unchanged and stays exercised by the
collections that do opt in, so granting one later is a one-line config change rather than a
revival of dead code.
The field is validated as a subset of the group's own secret_collections, rejects duplicates,
and cannot be combined with unclaimed, which by definition has no service accounts.
Withdrawing an account now also deletes its secret. DiffSecrets kept every secret belonging
to a live collection, which is right for the collection's own data but left the
__updater-service-account secret holding a key that had just been revoked along with the
account. Data secrets are untouched; only the service account secret, which the reconciler
owns, is removed.
Keeping the service account code exercised only holds if something exercises it, so the e2e
configs opt in too: one collection asks for an account while its neighbours do not, and the
update step both withdraws that account and grants one elsewhere, so creation, key generation
and deletion all still run. Left alone, every e2e config would have asked for nothing and the
comparison would have passed on zero service accounts either way.

Every claimed secret collection gets its own updater service account, and with it two more bindings in the
openshift-ci-secretsproject IAM policy. At the ~115 collections the Vault migration will onboard that is 230 bindings and roughly 63KB — on its own enough to push the policy past GCP's ~67KB cap. It is the last thing standing between the policy and the migration.Almost none of them are wanted. Group members can already write to every collection their group owns, via the group's own updater binding. The service account is for automation that cannot authenticate as a group member. Four collections have one today.
So a group now names the collections it wants one for:
Collections not listed still get their index secret and are still covered by their group's bindings. They just have no service account, no SA secret, and no service-account-scoped bindings.
Effect
At 115 collections / 50 groups, projected policy size:
The SA code is kept, not removed
It is unchanged and stays exercised by the collections that do opt in, so granting one to a team later is a one-line config change rather than reviving deleted or commented-out code.
Withdrawing an account also removes its secret
DiffSecretskept every secret belonging to a live collection, which is right for the collection's own data but left<collection>__updater-service-accountholding a key that had just been revoked along with the account. Only that secret is affected; data secrets and index secrets are untouched. This also fixes the same latent problem on the existingunclaimedpath, where the account was already being deleted while its secret stayed behind.e2e
Left alone, no e2e config would have asked for a service account,
GetDesiredStatewould have returned none, and the comparison would have passed on zero either way — the whole lifecycle would have stopped being exercised. So the configs opt in:alpha-secretsasks for one while the six collections beside it do not, and the update step withdraws that account while granting one tonew-secrets, so creation, key generation and deletion all still run against real GCP. The unclaimed test now has a claimed collection with an account next to the unclaimed one without, so that assertion means something again.The reconciler binary path is also overridable via
GSM_SECRET_SYNC_BINARY(defaulting to the container path), which is what makes the suite runnable outside CI.Ordering: this must merge before openshift/release#84712
group.LoadConfigparsessync-rover-groups/_config.yamlstrictly, so until this ships and its images are rebuilt the release PR's own presubmits fail on the unknown field. That PR addsupdater_service_accountsfor the three collections whose accounts are in use, and merging it is what fires the reconciler.One hazard in that order: between this image going live and the release PR merging, the reconciler would run new code against a config where nobody lists
updater_service_accounts, and would delete all four service accounts. It only fires if something else changes that file in the window, so it wants watching rather than blocking.Reviewer notes
secret_collections, rejects duplicates, and is rejected onunclaimedgroups.Summary
The GSM secret collection updater now creates dedicated updater service accounts only for collections listed in
updater_service_accounts.
