test(argocd): point azhi-riotpiao at the CNPG branch

The StatefulSet database could not attach its Longhorn volume, so the branch runs the database as a CNPG Cluster instead. This pins the Application to that branch for the test; it returns to the default branch once the branch merges.
feat(argocd): let ArgoCD reconcile azhi-infra from its private GitHub repo

+# etcd backend maintenance: compact, defrag, disarm NOSPACE.
+#
+# Why this exists
+# ---------------
+# etcd's backend file only grows. The apiserver compacts every 5m, but
+# compaction marks superseded revisions free *inside* the file; only `defrag`
+# returns that space to the filesystem. Nothing ran defrag, so the file grew
+# until it crossed the 2 GiB quota:
+#
+#   2026-10-07  backend 2,148,843,520 B (2.1 GB) on talos-cp-1 and talos-cp-3
+#               -> etcd raised NOSPACE on those two members
+#               -> etcd rejected ALL writes cluster-wide
+#               -> kubelets could not post node status: 3 nodes NotReady
+#               -> apiserver writes returned 500, the tunnel API path 502
+#
+# The live data was tiny: 15,943 keys, 69 MB after compaction. The rest was
+# dead pages. Recovery was `compact <current-revision>` then `defrag` per
+# member then `alarm disarm`. Compaction had also stalled while the alarm was
+# up, so `dbSizeInUse` read 100% of the file - defrag alone would NOT have
+# worked. Order matters: compact first, then defrag.
+#
+# The earlier revision of this file never ran, for two independent reasons:
+#   1. it existed only on branch fix/etcd-defrag-cron; the ArgoCD application
+#      `cluster-maintenance` tracks `main` (targetRevision: main), so the
+#      cluster never had the CronJob or the Secret.
+#   2. the image was quay.io/coreos/etcd, which has NO /bin/sh (verified:
+#      `exec: "/bin/sh": no such file or directory`). Any container that runs
+#      a shell script needs an image that ships one.
+# This revision fixes both: image bitnamilegacy/etcd (ships bash + etcdctl
+# 3.6.4, matching the 3.6.11 servers) pinned by digest.
+#
+# Cadence: every 15 days. Measured growth is ~29 MB/day, so a 15-day cycle
+# peaks near 500 MB - comfortably under the 2 GiB quota. The schedule is daily
+# and the script exits unless the UTC epoch day is a multiple of 15. That gives
+# an exact 15-day interval; `*/15` in the day-of-month field does not (it fires
+# on the 1st, 16th and 31st, which puts two runs one day apart).
+#
+# Safety
+# ------
+# 1. Compaction uses the MINIMUM revision across members. Compacting to a
+#    revision a member has not reached wedges that member - measured on
+#    2026-10-07, when talos-cp-2 froze ~1.2M entries behind the leader and
+#    needed a reboot to rejoin.
+# 2. A member whose raft applied index lags the leader by more than 100000 is
+#    skipped and reported. Defragging a frozen member reclaims nothing.
+# 3. Members are defragged one at a time. A defrag pauses the member's apply
+#    loop for the duration of the file copy.
+#
+# Credentials: Secret etcd-defrag-creds in kube-system, SOPS-managed in
+# k8s/argocd/secrets/etcd-defrag-creds.enc.yaml (ksops generator 00-secrets).
+# Its client certificate is signed by the cluster's etcd CA and expires
+# 2036-10; rotate it before then by re-running the mint and re-encrypting.
+#
+# Companion alerts (monitoring): etcd_mvcc_db_total_size_in_bytes /
+# etcd_server_quota_backend_bytes > 0.8, and an etcd NOSPACE alarm alert.

rock	71fce30506	test(argocd): point azhi-riotpiao at the CNPG branch The StatefulSet database could not attach its Longhorn volume, so the branch runs the database as a CNPG Cluster instead. This pins the Application to that branch for the test; it returns to the default branch once the branch merges.	2026-10-12 21:24:47 +08:00
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 pointing at ToyoGlobal/azhi-infra fails admission with 'repository not permitted'. Adding the URL is the whole gate. 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.	2026-10-12 20:54:00 +08:00

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.	2026-10-07 17:12:39 +08:00
