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).
Adds the pi coding-agent sandbox's cluster side:
- `k8s/infra/poimen/pi-agent-workspace-pv.yaml` — static hostPath PV + PVC for the sandbox /workspace (Longhorn cannot attach new volumes in this cluster; this gives real persistence and survived a pod delete/recreate test: marker file + 38 KB session.jsonl intact, the session answered from its own history afterwards).
- `k8s/argocd/secrets/pi-sandbox-secrets.enc.yaml` — the sandbox's API-key Secret, SOPS-encrypted (recipient from .sops.yaml, payload only: `encrypted_regex ^(data|stringData)$`), registered in the ksops generator. Round-trip verified against the live Secret.
- `terraform/files/coredns/Corefile` — `rewrite name pi.riotpiao.com ingress-nginx-controller...` so the hostname resolves in-cluster.
Note: the keys currently in that Secret are the ones leaked earlier and must be rotated; re-encrypt with `sops -e -i` after rotating.Reviewed-on: #54

- paperless-ai deployment using clusterzx/paperless-ai
- LLM via local api-gateway (reasoning model, no auth - phase 3 pending)
- Paperless API token SOPS-encrypted
- Auto-tags new documents, 5min scan interval
- Adds 'ai-processed' tag to classified documents
ArgoCD couldn't decrypt secrets.yaml because it was listed as a plain
kustomize resource. Move the 3 secrets (gotify-admin, gotify-tokens,
gotify-smtp) to k8s/argocd/secrets/ as .enc.yaml files processed by
the ksops generator, matching the repo convention.
Fixes ComparisonError: 'Object Kind is missing' (SOPS ciphertext
parsed as raw YAML).
- portfolio-secrets.enc.env: FORGEJO_TOKEN + LLM_API_TOKEN for api.riotpiao.com
- kustomization: secretGenerator for ksops handling at deploy time
- Will be SOPS encrypted with homelab age key before merge
Old root token and unseal keys were dead (lost access to the previous
Vault store). Wiped the S3 backend and vault-0, re-initialized fresh,
rotated these to match the new live unseal keys so ArgoCD's next sync
doesn't clobber them back to the dead ones.
Fixes controlplane.tftpl's install.wipe:true (should be false, live CPs already run false) and syncs coredns Corefile back to what's actually deployed (drops an unrolled-out, stale Kong-era rewrite).
Kong was retired 2026-08-19, replaced by the rock/homelab-frontend Go
gateway (single /v1/chat/completions endpoint, model routed via the
request body's "model" field per API.md). Old per-model baseUrls
(/v1/ornith, /v1/reasoning, /v1/qwen) all 404 against the new gateway.
Also flipping reasoning's supportsTools to true -- confirmed working via
live test now that reasoning runs Qwen3-32B instead of DeepSeek-R1.
- Runner egress: allow 192.168.1.160/32:443. forgejo.riotpiao.com resolves to
the ingress LB, inside the 192.168.1.0/24 block the NetworkPolicy denies, so
docker push hung until timeout.
- dind CA: also mount homelab-ca at /etc/docker/certs.d/forgejo.riotpiao.com/,
the path dockerd actually reads for per-registry trust.
- Pull secret: dockerconfigjson for the api namespace; /v2/ answers 401.
- AppProject: allow the Forgejo repo as a source for api-gw.
