fix(authup): give the migration hook only what a hook can see, and scope useHelmHooks to ArgoCD - #20

Conversation
…ope useHelmHooks to ArgoCD Helm applies a pre-upgrade hook BEFORE the release manifest, so the migration Job can only reference objects that already exist from the PREVIOUS release. It referenced several that do not. Dropped from the Job (via a `hook` flag on the shared helpers, so Deployment and Job stay one source per architecture rule 10): - the provisioning volume. `migration run` never scans <writable>/provisioning: ProvisionerModule is registered by createApplication(), which only the start command calls. The upgrade that first set server.provisioning.files left the hook pod in ContainerCreating on "configmap not found" until it timed out. - REDIS and SMTP. The migration builds config + logger + database only, no cache and no mail module, and both Secrets are ordinary release resources. - CLIENT_SYSTEM_SECRET. Its key inside the chart-managed auth Secret is conditional, so flipping auth.systemClientEnabled on broke the hook the same way. Kept, deliberately: - the writable directory. Under the image's NODE_ENV=production the logger opens <writable>/http.log and <writable>/error.log before the first query, and an uncreatable path is a hard ENOENT, not a degradation. - the config file. `migration run` loads authup.server.core.conf unconditionally, and the db keys only the file can carry (ssl, socketPath, replication, extensions, poolSize) decide how it connects and what it creates. Dropping the mount would have migrated over a plaintext connection with no error. The Job now reads it from a hook-scoped COPY at hook-weight -5, which also fixes the quieter half: the release ConfigMap holds the PREVIOUS release's content when the hook runs. Same reasoning that already makes the Job inline configEnv. - SECRETS_ENCRYPTION_KEY, whose key is conditional too. Rule 6's fail-closed posture outranks the one-off break: a migration that ever touches a wrapped column must not run without the key. A write-once KEK gets its own upgrade. The helpers now take (dict "context" $ "hook" bool) and `required` the context. That guard is load-bearing: helm renders with missingkey=zero, so a call site passing a bare `.` would have read every guard as false and emitted writable + tmp only, silently dropping the config file again. Separately, useHelmHooks=false was documented "set false for ArgoCD / Flux". Flux's helm-controller runs a real helm upgrade and honours Helm hooks, so turning them off there applies the Job as an ordinary resource, and Job.spec.template is immutable: the next upgrade that changes the pod template fails to patch it. The flag is now scoped to ArgoCD in values.yaml, NOTES warns when it is set, and architecture rule 19 records why a content-hashed Job name is not the answer (helm orders a plain Job after the Deployment and does not wait for it, which is the ordering the Job exists to provide).

… correct the records A follow-up audit found the comment justifying its retention was wrong. It said the key is unconditional "so it costs nothing", but an unconditional KEY is not an existing OBJECT: authup.auth.secretName resolves to the chart-managed auth Secret, an ordinary release resource, so the upgrade that drops auth.existingSecret in favour of a chart-managed password schedules a hook pod whose secretKeyRef target does not exist yet. That is the same failure this branch removed for CLIENT_SYSTEM_SECRET, and `migration run` builds no identity or provisioning module, so the value was pure cost. The hook now carries exactly two secret-backed entries: DB_PASSWORD and, deliberately, the KEK. Record corrections, all found by the same audit: - architecture.md rule 10 said "three helpers" (it is four: configEnv is inlined rather than flagged) and narrowed the DB_PASSWORD residual to an engine switch. It also misses two residuals the flag cannot reach: serviceAccountName (the ServiceAccount renders under serviceAccount.create, and a missing one fails pod admission with no container status), and the extraEnvVarsCM / extraEnvVarsSecret / extraVolumes passthroughs, whose targets land after the hook when shipped through extraDeploy. - references/authup.md listed `entities` and `subscribers` as file-only db keys. DB_ENTITIES and DB_SUBSCRIBERS exist. The six that carry the argument for mounting the config file (ssl, socketPath, replication, poolSize, charset, extensions) are genuinely absent from typeorm-extension's env reader; the bullet now says how to re-derive the list. - testing.md's NOTES recipe was a trap: helm excludes templates/ from .Files, so the obvious `.Files.Get "templates/NOTES.txt"` wrapper renders empty and BOTH directions of the assertion pass. Replaced with the inlining recipe, verified to give 1 and 0.

Follow-up audit pass (rendered-output correctness, adversarial check of the late fixes, completeness critic). One real defect in this branch, three false statements in the records, and three pre-existing issues split out. Fixed here (78e9708)
The hook now carries exactly two secret-backed entries: Three records were wrong, which matters because these files steer future work:

…fail on two config carriers Four follow-ups from the audit round, all decided on the PR. ct now runs upgrades (.github/configs/ct.yaml). Nothing in this repo had ever created a pre-upgrade hook on a cluster: `ct install` runs without --upgrade, so the migration Job and its hook-scoped ConfigMap were render-tested only, and the ordering claim rested on reading helm and gitops-engine source. `upgrade: true` gives two real `helm upgrade`s per ci values file, master's chart to this revision and this revision to itself. The first leg is the interesting one right now: master's ci/valkey-values.yaml has no server.configuration while this branch's does, so it IS the "first upgrade that introduces the config file with the migration hook on" scenario the hook-scoped copy exists for. ct skips that leg once a release bumps the middle digit (0.x reads that as breaking via a ~0.x.y constraint); the self-upgrade leg always runs. The kind job gets roughly 3x longer. The theme volume folds into the hook flag. It was a pair of deployment-only defines carved out for exactly the hook reason the flag now expresses, which left two calling conventions in one volumeMounts: block two lines apart, i.e. the most likely way the next mount lands on the wrong side. Net deletion, and the render is object-identical (it also drops two whitespace-only lines the old call-site guards emitted). themeEnv deliberately stays separate: it splits along a different axis, since configEnv is one define shared by the env ConfigMap and the Job's inlined env, and THEME_* has to stay in its reserved-key list. The migration Job name is capped at 63 (#21). Rule 9's trunc-52 base plus "-server" plus "-migration" reaches 69, and with no hand-written spec.selector the API server copies the Job name into the job-name / batch.kubernetes.io/ job-name pod labels, where a label VALUE stops at 63. A long release name therefore produced a Job the API server rejects, hanging the upgrade until the hook timeout. Rule 9 now records that it keeps names distinct, not short, and that 63 rather than 253 is the ceiling wherever a name becomes a label value or a DNS-1035 label. server.configuration together with server.existingConfigmap now fails the render (#23). The existing ConfigMap is the one that gets mounted, so the inline content was silently dropped, and that content is usually where db.ssl / socketPath / replication live: the operator believed TLS to the database was configured while the mounted file was somebody else's. Same shape as the auth.existingSecret guard right above it. Recorded in BREAKING.md. Closes #21 Closes #23
…elease names install The admin-console Service reached 66 characters. A Service name is a DNS-1035 label, capped at 63, so any release whose fullname hit 50 characters (a release name of about 43) was rejected by the API server and could not install at all. No opt-in flag needed, unlike the migration Job in #21. authup.component.fullname is now the single implementation: it takes the suffix, computes `min 52 (63 - len(suffix) - 1)`, truncates the base to that, then suffixes. All five component helpers and the migration Job go through it, so the Job also stops needing a post-hoc trunc and renders a clean -server-migration instead of a mid-word -server-mig. `min 52` is the load-bearing half. The derived budget is WIDER than 52 for short suffixes, and widening renames resources on releases whose fullname lands between 53 and 55 characters. A renamed Secret carrying helm.sh/resource-policy: keep orphans the old one and generates a fresh admin password and system-client secret, i.e. a silent credential rotation on upgrade. The budget may only ever tighten. Verified rather than assumed: rendering every release-name length from 3 to 53 against origin/master, the name sets differ at no length where master was installable, and the branch is installable at every length. Master first becomes un-installable at 40 with the migration Job enabled, 43 without. Marked breaking because names do move for releases in that range, even though none of them can currently exist in a cluster. Closes #24

…rect three records From CodeRabbit's review on #20. The NOTES warning fired whenever server.migration.enabled was set, but the Job it warns about renders only under `server.enabled` too. A UI-only deployment carrying a leftover migration flag was told its migration Job would break on upgrade, with no migration Job in the release. Rule 10 stated its own premise too broadly: "everything the Job references must already exist from the PREVIOUS release" is contradicted two sentences later by the hook-scoped config copy, which is created in the same hook phase at a lower weight. Now scoped to non-hook resources, naming the copy as the exception. testing.md and ci/valkey-values.yaml still described CI as install-only, which the `upgrade: true` added earlier in this same branch had already made false. The layers table, the ct section and the ci comment now describe the two upgrade legs, that helm-extra-args reaches upgrades as well, and that the first leg is skipped once a release bumps the middle digit. Not changed: the `hook-succeeded` delete policy on the hook-scoped ConfigMap. The review flagged it as unsafe before helm 3.16.3, on the grounds that the ConfigMap could be deleted before the weight-0 Job runs. It cannot, in any version this chart supports. In v3.14.0, v3.15.4, v3.16.2, v3.16.3 and v3.18.4 alike, pkg/action/hooks.go runs HookSucceeded deletion in a SECOND loop after the execution loop has finished every hook in the event, under the comment "If all hooks are successful...". helm/helm#13365 (3.16.3) only reverses the iteration order WITHIN that trailing loop, so dependencies are torn down after their dependents; it does not move deletion earlier. The diff 3.16.2 -> 3.16.3 is one line: `for _, h := range executingHooks` becomes a backwards index loop.
The naming change ships as fix(authup)!, so the ledger has to carry it. Nothing to migrate: every name that moves belongs to a release the API server already refused, because the admin-console Service exceeded 63 characters.

#17: what the pre-upgrade hook can actually see
Helm applies a pre-upgrade hook before the release manifest, so the migration Job can only reference objects that already exist from the previous release. The issue found the provisioning and configuration ConfigMaps; the class is wider, and one half of the suggested fix turns out to be unsafe.
I traced
server/core migration runin the monorepo before touching anything.defineCLIMigrationCommandbuilds exactly three modules: config, logger, database. No http, cache, mail, identity or provisioning module.Dropped from the Job (a
hookflag on the shared helpers, so Deployment and Job stay one source per architecture rule 10):server.provisioning.filesleft the hook pod inContainerCreatinguntil timeoutProvisionerModuleis registered bycreateApplication(), i.e. thestartcommand onlyREDIS,SMTPCreateContainerConfigErrorCLIENT_SYSTEM_SECRETauth.systemClientEnabledbroke the hook identicallyKept, deliberately (this is where the issue's suggested "writable + tmp only" would have caused a silent regression):
migration runcallsreadConfigRawFromFSunconditionally, and the db keys typeorm-extension's env reader does not name survive the env merge:ssl,socketPath,replication,extensions,poolSize,entities. Those decide how the migration connects and what it creates. Unmounting it would have migrated over a plaintext connection with no error at all.NODE_ENV=productionthe logger opens<writable>/http.logand<writable>/error.logbefore the first query; an uncreatable path is a hardENOENTfailure of the command.SECRETS_ENCRYPTION_KEY, whose key is conditional too. Rule 6's fail-closed posture outranks the one-off break: a migration that ever touches a wrapped column must not run without the key. A write-once KEK gets its own upgrade, and rule 10 now says so.So the config file needed a different fix than unmounting: the Job reads it from a hook-scoped copy at
helm.sh/hook-weight: "-5"(templates/server/configmap-migration-configuration.yaml). That also fixes the quieter half nobody had noticed: even in steady state the hook was mounting the release ConfigMap, which still holds the previous release's content when the hook runs. Exactly the reasoning that already makes the Job inlineconfigEnv.The release ConfigMap stays a tracked release resource, so
helm rollbackstill restores its content for the Deployment. Both ConfigMaps render from oneauthup.server.configurationContenthelper, so they cannot diverge.The helper signature
volumeMounts/volumes/secretEnv/configurationConfigMapNamenow take(dict "context" $ "hook" bool)andrequiredthe context. That guard is load-bearing, not decoration: helm renders withmissingkey=zero, so a call site passing a bare.reads every guard as false and emitswritable+tmponly, silently dropping the config file again. Verified it now fails the render instead.#18: useHelmHooks=false is ArgoCD-only
Verified all three of the issue's claims against primary sources, and one is wrong in a way that matters:
helm upgradeand honours Helm hooks (disableHooksdefaults false). Confirmed - the flag genuinely breaks Flux.Job.spec.templateis immutable and helm's three-way merge patch is rejected. Confirmed, reproduced.pre-install/pre-upgradeontoPreSyncandhelm.sh/hook-weightontosync-wave, so a chart shipping only Helm hooks already works under ArgoCD. The flag only chooses which annotation family drives the Job.Doc-only fix, which is the correct one rather than merely the smaller one. A content-hashed Job name would make the non-hook path apply-able under Flux but not correct: helm orders a plain Job after the Deployment and does not wait for it, so you would get an applied Job with none of the ordering the Job exists to provide. Recorded as architecture rule 19.
values.yamlnow scopes the flag to ArgoCD, and NOTES warns when it is set with the migration Job on.Verification
make test(lint + allci/*-values.yaml+ values coverage) andmake docs schemawith no drift.checksum/configuration. The only changes are the new hook ConfigMap and the narrowed Job.existingConfigmap/ none / provisioning-as-Secret). Every mount has a matching volume; no provisioning on the Job in any mode.hook-weight: -5claim is verified in helm source, not assumed:pkg/action/hooks.goapplieshook-succeededdeletion in a trailing loop after every hook in the event has run, so the ConfigMap outlives the Job. Same conclusion for ArgoCD:deleteHooks(hooksPendingDeletionSuccessful)is only reachable from the terminal-success branches ofSync().PreSync, andpre-install/pre-upgradeboth map toPreSyncso the ConfigMap and Job appear and disappear together.Known, not fixed here
server.existingConfigmap+ ArgoCD. The Job mounts the operator's ConfigMap, which the chart cannot annotate. If it is rendered by the same Application it lands in theSyncphase and is missing atPreSync. Pre-existing, not fixable inside the chart. A NOTES line would not help since ArgoCD never renders NOTES.ct installruns without--upgrade, so the pre-upgrade Job and its ConfigMap are never created on kind.ci/valkey-values.yamlnow setsserver.configuration, which buys install coverage for the release ConfigMap and render coverage for the copy. Addingupgrade: truetoct.yamlwould close it properly; that felt like a separate call.hookflag instead, sodeployment.yamlnow has both calling conventions two lines apart. Folding the two theme volume defines into the flag would be a net deletion and unify it. Left out to keep the diff on the issues; happy to do it as a follow-up.Not user-facing values
