pi d4e9dbf350 refactor(iam): retire terraform/zitadel, provision through the API
The Terraform root module duplicated a writer that the provisioning script could
be, and its state carried generated client secrets. Declare the objects in the
script instead: project, 19 roles, 12 OIDC apps, applied through the management
API with the iam-admin PAT. State is a 0600 JSON file under ~/.config/zitadel.

Also add zitadel to the Cloudflare tunnel hostname list, with the import command
and the note that the tunnel's Public Hostname entry is a separate dashboard
step: DNS alone yields a 404 from the tunnel.

pi be44a576d4 fix(iam): own the Zitadel login keypair through ksops
The chart generated the login RSA keypair on every render, so
checksum/secret-login-service-key changed each time and both Zitadel
Deployments stayed permanently OutOfSync.

Adopt the live keypair into k8s/argocd/secrets/zitadel-login-service-key.enc.yaml
(SOPS, age recipient from .sops.yaml), list it in the ksops generator, and point
login.loginServiceKeySecretName at it. The chart then stops generating the
keypair and the Deployment checksums become deterministic.

pi 39081222a3 fix(iam): stop the setup hook running after first boot
A PreSync setup run is not harmless once the instance exists: it replays every
repeatable migration on every sync, and interrupting one leaves a
system.migration.started event with no matching done. ZITADEL then waits
forever on 'migration already started'. That deadlocked this instance twice
(projections.projects4, then repeatable_delete_stale_org_fields).

Move the setup job's hook from pre-install,pre-upgrade to post-delete so ArgoCD
sync never runs it. Re-enable deliberately for a schema upgrade.

pi 7e5b793670 fix(iam,edge): freeze first-boot and wire the WireGuard CIDR variable
Zitadel first boot completed on 2026-10-26, so set FirstInstance.Skip: true and
initJob.enabled: false. Without Skip, every sync re-runs machinekeyWriter and
silently rotates the iam-admin key that terraform/zitadel authenticates with.

Also wire wireguard_allowed_cidr into the WireGuard security-group rule; the
variable was declared but the rule still used relay_admin_cidr, which blocks
the homelab peer unless its egress address happens to match the operator CIDR.

pi 6ebecec1c4 fix(zitadel): raise setup job deadline to 20m
The chart default killed zitadel-setup at ~5.5 minutes while it was still
replaying projections.projects4, which failed the whole PreSync and left the
Application OutOfSync/Missing. 1200s leaves room for a cold database without
masking a genuine hang.

rock 091ecdd7bb feat(edge): Terraform for the China-facing relay and Cloudflare DNS
Adds terraform/edge, a root module with two providers:

- Cloudflare 5.28.1: CNAMEs to the existing tunnel, plus an opt-in resource that
  can take the tunnel ingress list over when manage_tunnel_config is true. It is
  off by default because that resource REPLACES the whole list, and the tunnel is
  remotely managed from the dashboard today.
- Tencent Cloud 1.83.38: VPC, subnet, security group with three rules, key pair,
  one CVM relay with cloud-init (WireGuard listener, forwarding sysctls, Caddy),
  and DNSPod A records for the .cn hostnames.

The design keeps the homelab inbound-free: the relay terminates TLS in China and
forwards over a WireGuard tunnel the cluster dials outbound. Cloudflare keeps
serving every existing hostname untouched.

Verified: terraform init succeeds for both providers, fmt clean, validate
reports 0 errors, and plan resolves to 10 creates with placeholder variables.
Provider-side name validation caught a real bug during that run: key pair and
security group names allow only letters, digits and underscore, so the derived
names use underscores.

Not applied. Credentials come from CLOUDFLARE_API_TOKEN,
TENCENTCLOUD_SECRET_ID and TENCENTCLOUD_SECRET_KEY; the WireGuard private key is
TF_VAR only. State is local and git-ignored like terraform/zitadel.

Blocked on facts this module cannot invent: the real .cn domain, whether it has
an ICP filing, the CVM image ID, the operator CIDR, and the homelab WireGuard
public key.

rock e335694cbb fix(sops): repair the generator list and rotate the Zitadel masterkey
Two defects in the ksops generator:

1. The `zitadel-masterkey.enc.yaml` entry was added with two-space indentation
   while every other entry uses four. YAML rejected the list, and kustomize
   reported it as `loading generator plugins ... MalformedYAMLError: yaml: line
   39`. That failed the whole sops-secrets application, so no Secret in that app
   could be created. Verified by running the same kustomize build inside
   argocd-repo-server: exit 1 before the fix, exit 0 with 33 manifests after it.

2. The masterkey value was generated during the first verification pass and
   appeared in that session's output. Rotate it now, before the instance exists:
   a fresh 32-byte value, SOPS-encrypted, with the offline copy updated. No
   ZITADEL data exists yet, so rotation costs nothing. After the first sync it
   would mean re-encrypting system.encryption_keys.

The offline copy lives outside the repo at ~/zitadel-masterkey.offline (0600).

rock d1a7d3be6e fix(oidc): remove the API-server restart Jobs from GitOps
The oidc-bootstrap ArgoCD Application runs with selfHeal and prune. Three
Jobs in restart-apiserver.yaml kill the kube-apiserver process on each
control plane, and bootstrap.yaml carried a fourth Job that deletes the
mirror pods. ArgoCD recreated a deleted Job within two minutes, so the
kill repeated and every API server reached CrashLoopBackOff.

Remove all four. The OIDC authenticator already loaded, so the one-shot
restart is not needed again.

nothing. Add those rules to the ClusterRole.

macos-bluebubbles pins itself to a node labelled workload=imessage, and no

rock 6ee22401fd fix(sops): drop the orphan forgejo-registry-pat file
ksops failed the whole sops-secrets application on this file: it declares
Secret forgejo-registry-pat in namespace forgejo, and no such namespace exists.
The failure blocks every other file in the generator list, including
zitadel-masterkey.

The same Secret name is already generated in namespace api by
forgejo-registry-pat-api.enc.yaml, and that is the copy the gateway reads. The
forgejo namespace copy is stale: Forgejo runs in namespace cicd, and namespace
forgejo was never created.

Remove the file and its generator entry. ArgoCD never created the Secret, so
pruning has nothing to remove.

rock 979a413a5b feat(iam): read the Zitadel bootstrap token from .env
ZITADEL_BOOTSTRAP_TOKEN and ZITADEL_URL now live in .env and .env.example, the
same shape the Authentik variables use. The line is present and empty: the PAT
does not exist until the chart's setup job creates the iam-admin machine user on
the first sync, so a value cannot be minted ahead of time.

The provisioning script loads .env itself instead of relying on the caller to
source it, and resolves the token in a fixed order: ZITADEL_BOOTSTRAP_TOKEN,
then the cached file under ~/.config/zitadel, then the cluster Secret. The .env
value wins so a human can paste a rotated token without touching the cluster;
the cluster Secret remains the only source that always reflects a rotation.

.env stays git-ignored. It already holds the live Authentik secrets, and this
change does not move them.

Not exercised against a live instance: the kube-apiserver on talos-cp-1 is in
CrashLoopBackOff, so kubectl only works against cp-2 or cp-3 right now.
2026-10-24 03:38:21 -07:00
rock 2f62351731 feat(iam): one script to provision Zitadel end to end
scripts/iam/zitadel-provision.py replaces the manual sequence that
provision-rbac.py did for Authentik. Phases: keys, apply, secrets, users,
verify. `all` runs keys -> apply -> secrets -> verify; users stays manual
because the password hash must come from a human, one user at a time.

- keys: extract the chart's iam-admin machine key and PAT to ~/.config/zitadel
  at 0600, outside the repo.
- apply: terraform apply terraform/zitadel with the machine key.
- secrets: write generated client secrets into the SOPS files, write client ids
  into the plain manifests that carry them, write machine keys per agent.
  Requires an exactly-one-match regex before it edits a manifest, prints the
  diff without --apply-config, and is a no-op when the value already matches.
- users: import a human user with the Django pbkdf2_sha256 hash converted to the
  passwap MCF form ZITADEL accepts.
- verify: discovery endpoint, client count, and it refuses to clear cutover
  while the groups-claim action is disabled.

Design points that came out of review:
- Multi-document SOPS files (minio) are rewritten whole, because `sops set`
  cannot address one document. sops reads the creation rule from the filename,
  so the temp file is passed with --filename-override; without it sops finds no
  matching rule and refuses. Ciphertext is staged in the destination directory
  and installed with os.replace, so the mode is preserved and EXDEV is
  impossible. SIGTERM/SIGINT trigger cleanup of the decrypted temp file.
- homarr is listed as manual: the live workload mounts Secret homarr-oidc, which
  no SOPS file in git defines, and the tracked homarr-auth-oidc.enc.yaml has no
  consumer. Writing the new secret into the orphan file would report success
  while the dashboard kept the old one.
- Secrets never enter argv: curl reads its config from stdin, so the PAT and the
  password hash do not appear in ps.

.gitignore: allow this one script through the scripts/iam/*.py ignore rule (it
embeds no credential), and ignore authentik-m2m-tokens.env, which holds live M2M
tokens and was one `git add -A` away from being committed.

Checks: py_compile clean, --help lists every phase, convert_hash verified on a
synthetic hash, the 3-document SOPS rewrite tested on a real copy (3 documents
survive, value set, second run unchanged, mode 644 kept, no temp left), all
three client-id regexes match exactly once, dry-run leaves the manifests
untouched. Reviewer round: BLOCK on the sops creation rule, the orphan homarr
Secret, the missing client-id writes and argv exposure; all fixed and
re-reviewed to SIGN-OFF.

Not run against a live ZITADEL: no instance exists yet.

rock f81ff0e2fc feat(iam): declare Zitadel identity objects in Terraform
Adds terraform/zitadel: the provisioning half the ArgoCD wiring left open.
It declares 1 project, 19 project roles, 12 OIDC applications, 5 machine users
plus keys, one API application for the gateway, project grants, per-agent claim
metadata, and a disabled groups-claim action.

Facts established while writing it:

- Client IDs cannot be preserved. ZITADEL v4.19.2 CreateOIDCApplicationRequest
  has no client_id field, and provider 3.8.7 rejects a settable application id
  (terraform validate reports "Invalid or unknown key"). Plan §3.2 assumed a
  client_id-preserving re-point; every consumer now also changes client ID.
- Role keys equal the existing group names, so the groups claim can be
  byte-identical and no RBAC file changes. v4.19.2 allows role keys of 1-200
  characters with no character-set restriction.
- Machine users get JWT profile keys, not passwords. Per-agent claims move to
  user metadata and reach tokens only through the groups-claim action.
- The action stays gated: enable_groups_claim_action defaults to false because
  the action runtime API is unverified. Two validations stop a null script from
  reaching file().

Checks: terraform fmt -check -recursive clean, terraform validate 0 errors,
plan reaches only the expected missing-credentials error, structural gate
0 error / 0 warning, and one reviewer round: BLOCK on a plan-time
fileexists(null) and on the missing api-gw machine path, both fixed, re-reviewed
to SIGN-OFF.

State is local and git-ignored; it carries generated client secrets and machine
keys. Move it to MinIO before a second operator applies.

Not applied: no Zitadel instance is running yet.

rock cb1219bf96 feat(iam): wire Zitadel into namespace iam under ArgoCD
Coexistence wiring for the Authentik replacement: ZITADEL gets its own CNPG
cluster, SOPS masterkey, Helm values and ArgoCD Application in namespace iam.
Authentik keeps serving; no consumer is moved and no Authentik object changes.

- k8s/infra/databases/zitadel-db.yaml: CNPG Postgres 16.2, 3 instances
- k8s/infra/iam/zitadel-values.yaml: chart 10.4.0 pinned, DSN from the CNPG
  secret, masterkey from a Secret, metrics ServiceMonitor, second-sync caveat
- k8s/argocd/apps/30-security.yaml: Application named zitadel, wave 3,
  automated sync deliberately absent for the first sync (chart PreSync hook
  re-run risk)
- k8s/argocd/secrets/zitadel-masterkey.enc.yaml: 32-byte masterkey, SOPS
- k8s/infra/monitoring/alerts/svc-zitadel-rules.yaml: target-down, login-UI,
  crash-loop and PreSync-job-failed rules
- terraform/files/coredns/Corefile: in-cluster rewrite for the zitadel host

Not applied. The cluster is mid-incident: vault-0 and authentik-server are 0/1,
authentik-db-2 has 14 restarts, prometheus-0 is 1/2 CrashLoopBackOff and
kube-state-metrics has 1925 restarts. Two manual steps still gate the first
sync: the Cloudflare Tunnel public hostname plus a proxied CNAME, and
terraform apply + make apply-cp for the CoreDNS rewrite (Talos-owned).

The offline masterkey copy is at ~/zitadel-masterkey.offline (mode 600). Move it
to sealed storage and delete it before the first sync. Losing it makes every
encrypted ZITADEL value unreadable.

rock 8e9ac37583 chore(argocd): delete the azhi-riotpiao Application
The Application pointed at github.com/ToyoGlobal/azhi-infra, branch
feat/azi-riotpiao-cnpg, path k8s/overlays/azi-riotpiao. It never reconciled:
status stayed Unknown because the source repository could not be read, and the
destination namespace azi-riotpiao was never created. ArgoCD reported it as an
OutOfSync managed resource of homelab-root with nothing behind it.

Also drops the ToyoGlobal URL from the AppProject allowlist. No manifest from
that repository is referenced any more, so the allowlist entry is dead weight.

Not touched here, because it is not in git: Secret azhi-infra-github in
namespace argocd holds the read-only GitHub credential for that repository.
Delete it separately once no other Application needs the repo.

The live Application object was deleted by hand. Until this commit reaches
main, the next homelab-root sync recreates it, because main still declares it.

rock e93d4ba86c fix(cert-manager): restore wildcard renewal and drop per-host TLS
The ACME DNS-01 self-check resolved through CoreDNS and never saw the TXT
record. The wildcard renewal stalled on 2026-09-23 and riotpiao-com-tls
expired on 2026-10-23. Every Cloudflare Tunnel origin then failed with
"x509: certificate has expired or is not yet valid".

Changes:

- cert-manager: pin the self-check to the public resolvers with
  --dns01-recursive-nameservers and --dns01-recursive-nameservers-only.
  Verified against Let's Encrypt staging: the challenge went valid and the
  certificate issued.
- comfyui and forgejo: drop the per-host tls blocks and the
  cert-manager.io/cluster-issuer annotations. The wildcard covers both
  hosts, and the per-host certificates (comfyui-tls, forgejo-tls) expired
  with the wildcard.
- riotpiao-com-cert: document the wildcard as nginx's default certificate
  and the zero-downtime renewal path.

Renewal now runs 30 days before expiry, writes the same secret, and nginx
hot-reloads without a pod restart.

rock d21ee9630f fix(longhorn): retire the failed 2TB PERC disk on talos-cp-2
The disk behind /var/lib/longhorn-disk4 (sde1, 2TB PERC H710P virtual disk)
failed: 54 million SCSI I/O errors and climbing at ~7,000/minute, against 3 on
every other device on the node. Its XFS filesystem hung, so five Longhorn
replica processes and the longhorn-manager blocked in uninterruptible D state
in openat and unlinkat. D-state processes cannot be killed, so they held the
node's three replica rebuild slots permanently: no new replica could start on
talos-cp-2 and every new volume there failed to attach with DeadlineExceeded.
That is what stopped the azhi database from coming up.

Removed from all three declarations so it cannot come back:
- terraform.tfvars.local.bak, longhorn_disks for talos-cp-2
- the Longhorn add-disks Job, which would otherwise re-register it
- the Job's disk-count guard, 5 -> 4, or it would fire on every run once the
  disk is gone

The running cluster already has the disk fenced
(allowScheduling=false, evictionRequested=true); the replicas are evicted and
the device retired at the controller after that.

rock 949ae5cb38 feat(argocd): let ArgoCD reconcile azhi-infra from its private GitHub repo
The homelab AppProject allowlist had no azhi repository, so an Application

The Application itself targets the repository default branch
(harness/staging-slice), not main, and path k8s/overlays/azi-riotpiao. That
overlay renders postgres and the API into namespace azi-riotpiao.

The two Secrets the namespace needs stay out of Git: acr-pull carries the ACR
pull credential and azhi-riotpiao-app-env carries the database credentials,
the JWT secrets and the AES key.

rock abfdda5f57 fix(etcd): add a working 15-day defrag CronJob under the backend quota
etcd's backend file only grows: the apiserver compacts every 5m, but compaction
marks superseded revisions free inside the file, and only defrag returns that
space to the filesystem. Nothing ran defrag, so on 2026-10-07 the file reached
2,148,843,520 B, crossed the 2 GiB quota on talos-cp-1 and talos-cp-3, and etcd
raised NOSPACE. From then on etcd rejected every write cluster-wide: kubelets
could not post node status (3 nodes NotReady), apiserver writes returned 500 and
the tunnel API path returned 502. Live data was 15,943 keys, 69 MB after
compaction - the rest was dead pages. Compaction had also stalled while the
alarm was up, so dbSizeInUse read 100% of the file; defrag alone would have
reclaimed nothing. Compact must come first.

An earlier revision of this CronJob never ran, for two independent reasons, both
fixed here:
- its image quay.io/coreos/etcd ships no /bin/sh, so command: [/bin/sh, -c]
  failed with exec: "/bin/sh": no such file or directory
- it existed only on a side branch while the ArgoCD application
  cluster-maintenance tracks main, so the cluster never had it

Contents:
- CronJob etcd-defrag (kube-system): daily at 03:00, acts only when the UTC
  epoch day is a multiple of 15. That is an exact 15-day interval; */15 in the
  day-of-month field fires on the 1st, 16th and 31st, putting two runs one day
  apart.
- Image bitnamilegacy/etcd:3.6.4 pinned by digest, ships bash and etcdctl 3.6.4
  against the 3.6.11 servers.
- Compaction uses the MINIMUM revision across members, so a lagging member is
  never compacted past its own revision. Measured 2026-10-07: talos-cp-2 sat
  ~1.2M entries behind the leader with a frozen raft term and needed a reboot
  to rejoin.
- Defrag skips any member whose applied index lags the leader by 100k+, and
  runs one member at a time since defrag pauses that member's apply loop.
- Secret etcd-defrag-creds (SOPS/ksops, kube-system) carries the etcd CA plus a
  client certificate signed by the cluster's etcd CA, valid to 2036-10.

  cluster-maintenance tracks main (targetRevision: main), so the cluster never
  had the CronJob or its Secret

This revision fixes both and records the 2026-10-07 incident:
- image bitnamilegacy/etcd:3.6.4 pinned by digest (ships bash and etcdctl 3.6.4,
  matching the 3.6.11 servers)
- 15-day cadence by UTC epoch-day modulo; */15 in day-of-month fires on the 1st,
  16th and 31st, which puts two runs one day apart
- compacts to the MINIMUM revision across members, so a lagging member is never
  compacted past its own revision (measured: talos-cp-2 froze ~1.2M entries
  behind the leader and needed a reboot to rejoin)
- skips defrag on a member whose applied index lags the leader by 100k+
- documents that compact must precede defrag: compaction had stalled while the
  NOSPACE alarm was up, so dbSizeInUse read 100% of the file and defrag alone
  would have reclaimed nothing

harness 1ce9f86635 feat(etcd): weekly defrag CronJob to stay under the etcd backend quota
etcd's 2 GiB quota was reached on 2026-10-07 (backend 2.1 GiB, ~73 days of
churn). etcd raised NOSPACE and refused all writes, so kubelets could not post
node status: three nodes went NotReady and the tunnel origin pods on them
disappeared. Recovery was compact + defrag + alarm disarm per member.

The apiserver compacts every 5m, but compaction never shrinks the backend file -
only a defrag returns space, and nothing scheduled it. This adds:

- CronJob etcd-defrag (kube-system, Sundays 03:00): compact to the current
  revision, defrag each member sequentially, disarm NOSPACE, print before/after.
- Secret etcd-defrag-creds (SOPS/ksops, k8s/argocd/secrets): etcd CA plus a
  CN=etcd-defrag client cert signed by the cluster's etcd CA (expires 2036-10).

Applied by the existing apps: cluster-maintenance (directory) and 00-secrets
(ksops generator).

rock 2d9e3abee8 fix(oidc): match /proc/<pid>/comm instead of cmdline when signalling the API server
Exit code 143 proved the previous job killed itself: the script's own cmdline contains the
string 'kube-apiserver', so it matched its own process. Matching comm (== 'kube-apiserver')
and skipping $$ removes that failure mode. Staggered 2 minutes apart.

rock 9fa8d9cf60 fix(oidc): restart the apiservers by signalling the process, not by deleting the mirror pod
Static pods survive mirror-pod deletion, so the first bootstrap job had no effect.
These jobs share the host PID namespace and SIGTERM the kube-apiserver process itself,
staggered by 100s so only one control plane restarts at a time.

rock 2e4fad3bf7 fix(oidc): use curlimages/curl for the bootstrap job (bitnami/kubectl tag did not exist)
The first job could not pull its image; this one deletes the apiserver pods via the
in-cluster API with the mounted service-account token instead of a kubectl image.
