ZITADEL sends verification codes and password resets by SMTP only, and this
cluster has no mail path. Every human user therefore sits at
verified_email = empty and can never finish a first login, at ZITADEL or at
Forgejo.
Add an smtp-gotify relay in the iam namespace: it accepts plain SMTP on :2525
and forwards each message to the existing Gotify instance, so codes arrive on
the phone through gotify/igotify instead of email.
Point DefaultInstance.SMTPConfiguration at that Service with TLS off, because
the relay speaks plain SMTP inside the cluster. The relay holds the Gotify app
token in a SOPS-encrypted Secret; values never carry the token.
Sign-in failed with "Could not create session for user". The ZITADEL API
logged, on every session call:
authz: verify access token -> invalid token
token verifier repo: issuer does not match: Expected
https://zitadel.riotpiao.com, got: login-client
zitadel-login: [Password] Could not update session
The hosted Login UI authenticates as the machine user `login-client`. That
user did not exist in this instance, because the chart's setup job creates it
and setupJob is disabled after the first sync. Without the user the UI cannot
write a session, so no one can sign in, at ZITADEL or at Forgejo.
Disable the hosted Login UI so ZITADEL serves its built-in login, which needs
no machine user. Re-enable only after creating `login-client` and registering
the public key that matches zitadel-login-service-key.
Also register both callback spellings for the forgejo and paperless apps: the
callback path follows the login-source name, so a rename between authentik and
zitadel must not break sign-in.
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.
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.
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.
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.
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.
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.
