- namespace: PodSecurity privileged, needed for /dev/kvm + privileged QEMU
- storageclass: 1 replica, strict-local, WaitForFirstConsumer
- deployment: nodeSelector workload=imessage + matching NoSchedule toleration,
Recreate strategy (two QEMU procs on one qcow2 corrupts it), no readiness
probe (guest install is interactive and takes many minutes)
- services: ClusterIP only; VNC is an unauthenticated console, reach it with
port-forward, never an Ingress
- networkpolicy: default-deny, opt-in via sms-client=true on port 1234
argocd-server ran --insecure (plain HTTP :8080) while its Helm-managed
Ingress set ssl-passthrough: true, which sends nginx's raw TLS handshake
straight to the pod - HTTP server can't complete a TLS handshake, nginx
logged 502 (peer closed connection in SSL handshake). Compounded by a
second, conflicting Ingress for the same host in
k8s/bootstrap/ingress/ingress.yaml - two Ingress objects on one host is
undefined nginx routing behavior. Disabled the Helm-managed Ingress
(enabled: false) so ingress.yaml's passthrough Ingress is the sole
source of truth, and set server.insecure: false so argocd-server
actually terminates TLS itself, matching passthrough's requirement.
ArgoCD directory.include uses Go filepath.Match glob syntax, not shell
brace expansion - {a,b,c} silently matched nothing, only the original 2
files stayed tracked.
homelab-ca was referenced by 6 manifests (authentik, forgejo-runner,
blackbox-exporter, management-service) as a CA trust ConfigMap but never
existed anywhere - not in git, not live in cluster. Generated a new
10-year self-signed root CA, wired it as a ClusterIssuer (cert-manager
namespace) and distributed the public cert as a ConfigMap to every
consuming namespace (iam, cicd, monitoring, sqs). Private key lives only
in the encrypted Secret. Widened cert-manager-issuers' directory include
glob rather than creating a new Application - destination.namespace is
just a fallback default on a plain directory source, not a transformer,
so it doesn't fight with each ConfigMap's own explicit namespace.
Also adds grafana-oidc secret (GF_AUTH_GENERIC_OAUTH_CLIENT_SECRET),
same pre-existing gap as grafana-admin - was meant to come from a deleted
manual script, value already available in .env.
nodeSelector still targeted az-a/talos-cp-1 from before the 3-CP topology
change. talos-cp-2 (az-b) has the dedicated Longhorn disks now, so the
pod's zone pin and the PVC's only viable replica location never matched
- ReplicaSchedulingFailure: disks are unavailable, pod stuck
ContainerCreating waiting on AttachVolume.
Vault's S3 storage backend needs AWS_ACCESS_KEY_ID/AWS_SECRET_ACCESS_KEY
from vault-minio-creds, previously generated by a helmfile presync hook
that no longer exists post-Terraform/helmfile removal. Sourced from the
same MINIO_ROOT_USER/PASSWORD already in .env. vault-unseal-keys still
missing separately — needs a live 'vault operator init' run, deferred.
PVC sat Pending for 17 days — storageclass.storage.k8s.io "longhorn-wffc"
not found. Only longhorn, longhorn-cnpg, longhorn-static exist. Straight
naming drift, no such class was ever created.
- Replace all forgejo.riotpiao.com repo URLs with [email protected] SSH URLs
- Enables immediate GitOps sync without waiting for Forgejo mirror setup
- Includes ingress-nginx now fully ArgoCD-managed (wave 0)
- SOPS secrets can now sync and decrypt TLS certificates
ADDED:
- CloudNativePG (CNPG) Database Pattern section
- Explains shared 'app' user model (not per-app roles)
- Documents bootstrap.sh credential distribution pattern
- Working examples (Forgejo, Authentik)
- Prescriptive DO/DON'T guidance for new apps
FIXED:
- Storage topology: 3-node HA (not "sole Longhorn node")
- Verified: all 17 PVCs have replicas across all 3 nodes
- Updated last-modified date
This documents the architectural pattern established during CNPG refactor.
Fresh authentik deployment runs ~100 database migrations which takes 15-20
minutes. Previous startup probe failureThreshold of 60 (10 minutes) killed
the pod before migrations could complete, causing infinite restart loop.
Increased to 120 failures (20 minutes) to allow migrations to finish.
Fixes: nginx 503 due to pod never becoming Ready.
Authentik migrations need to CREATE SCHEMA (not just tables in public schema).
This requires GRANT CREATE ON DATABASE, not just schema-level permissions.
Added to PostSync Job:
- GRANT CREATE ON DATABASE authentik TO authentik
- GRANT CREATE ON DATABASE temporal TO temporal
- GRANT CREATE ON DATABASE temporal_visibility TO temporal
App user can grant these (it owns the databases).
Removes duplicate longhorn-kafka StorageClass managed by Kafka chart.
All applications now use single 'longhorn' StorageClass (3 replicas, Immediate binding).
Changes:
- Kafka chart: use 'longhorn' instead of 'longhorn-kafka'
- Delete Kafka StorageClass template (no longer needed)
- Update longhorn-storageclass.yaml to match deployed config (Immediate, not WaitForFirstConsumer)
Existing Kafka PVCs remain bound to old longhorn-kafka StorageClass (safe - no data loss).
New PVCs will use unified 'longhorn' StorageClass.
Minio operator requires privileged securityContext. Without these labels,
StatefulSet stuck at 0/0 replicas (PodSecurity admission blocks pod creation).
CoreDNS rewrites *.riotpiao.com → ingress-nginx-controller but bootstrap
deployed as ingress-nginx-bootstrap-controller. Service alias makes both work.
- Add explicit tls block with riotpiao-com-tls secret
- Enables HTTPS access to https://forgejo.riotpiao.com
- Matches wildcard certificate (*.riotpiao.com)
The file comment mentioned TLS should be handled via default-ssl-certificate,
but explicit TLS blocks are needed for proper HTTPS routing.
