Changes:
- k8s/infrastructure/longhorn/longhorn-taint-toleration.yaml: new Setting
to tolerate node-role.kubernetes.io/control-plane:NoSchedule taint,
allowing Longhorn DaemonSet to run on cp-2/cp-3 (not just cp-1)
- k8s/infrastructure/longhorn/longhorn-nodes.yaml: explicit Node CRDs for
talos-cp-2 and talos-cp-3 (auto-discovery doesn't work when nodes have
taints; these define /var/lib/longhorn as the storage path)
- k8s/infrastructure/longhorn/longhorn-wffc-storageclass.yaml: bump
numberOfReplicas from 1→3 (true HA: each volume gets 3 copies across
3 nodes; if one node fails, 2 others still have the data)
- k8s/infrastructure/longhorn/kustomization.yaml: add new resources
Root cause: Longhorn was only running on talos-cp-1 (.213) because cp-2/cp-3
have the control-plane taint and Longhorn DaemonSet had no matching toleration.
Every workload with a PVC was forced to schedule on cp-1 (via nodeSelector or
implicit co-location with the storage), defeating the entire purpose of a 3-node
HA cluster.
With this fix:
- Longhorn manager runs on all 3 nodes
- Storage is replicated 3x (erasure-coded across nodes)
- Pods can schedule on any node without PVC attachment failures
- True HA: lose 1 node, cluster still serves all volumes
Adds missing CLIENT_SECRET env injection + nodeSelector constraint:
- k8s/argocd/bootstrap/forgejo.yaml: inject GITEA__oauth2__CLIENT_SECRET
from forgejo-oidc Secret (created by authentik-provision Job), and pin
pods to talos-cp-1 via nodeSelector (only node with Longhorn storage —
gitea-shared-storage PVC can't attach on cp-2/cp-3)
Root cause chain for 'Forgejo SSO not working':
1. Authentik 2026.5.5 requires explicit grant_types on OAuth2 providers
2. Old provision script never set it → all providers had grant_types=[]
3. /authorize returned 'Invalid grant_type for provider' → all SSO broken
4. Fixed in k8s/security/iam/scripts/authentik-provision.py (commit be2a56c)
+ successfully re-ran via iam-jobs Application sync
5. But Forgejo deployment still missing CLIENT_SECRET env var → no creds
6. Forgejo bootstrap App used inline valuesObject (chicken-egg with git
repo self-hosting), but missing the extraEnv block that was only in
k8s/security/ci-cd/forgejo-values.yaml → CLIENT_SECRET never injected
All 4 OAuth2 providers now have correct grant_types=['authorization_code',
'refresh_token'], Forgejo pods now have CLIENT_SECRET env, and pods are
constrained to the storage node. SSO login flow should now work end-to-end.
CLAUDE.md was previously excluded from version control entirely (treated as
private local notes, with CLAUDE.example.md as the only git-tracked
counterpart). No longer justified - the file contains no secrets, just
architecture notes, private RFC1918 IPs, and operational lessons (same
sensitivity level as README.md, which is already tracked). Removing the
CLAUDE.md gitignore rule and committing it for the first time.
CLAUDE.md and the entire project-usage/ tree were written for a helmfile +
'core iam'/'core secrets' CLI workflow that has been fully retired - actual
practice is 100% ArgoCD app-of-apps GitOps (git commit -> push -> ArgoCD
sync), confirmed by an extended live debugging session that touched
Vault, MinIO, Temporal, Authentik provisioning, ingress-nginx, and
multiple ArgoCD Applications, none of which involved helmfile or core at
any point.
CLAUDE.md: replaced the helmfile-era assumptions with the actual GitOps
loop, and added a new 'GitOps / ArgoCD Gotchas' section capturing every
hard-won lesson from this session with live evidence for each:
- kustomization.yaml resources: allowlists silently dropping new files
- kustomization.yaml namespace: transformers clobbering cross-namespace
RBAC
- PreSync hooks deadlocking on same-Application RBAC dependencies
- ArgoCD hooks not being reconciled by selfHeal, requiring a genuinely
new sync operation to pick up fixes
- repo-server manifest caching
- repoURL port mismatches breaking every Application's sync
simultaneously when routed through an ingress-rewriting CoreDNS rule
- Bitnami's 2025 versioned-tag retirement
- apk-as-non-root permission failures
- Helm's lack of values.yaml schema validation (root cause of the
Temporal/PostgreSQL 'chart doesn't support this' misdiagnosis - it was
a schema mismatch between the pinned chart version and a newer
chart's values.yaml example, silently a no-op)
CLAUDE.example.md: fully rewritten as a sanitized, hardware-generic
template (explicit notice at top) - same lessons, genericized away from
this specific homelab's IPs/hostnames/secrets, intended to be reusable by
anyone running a similar bare-metal Talos + ArgoCD topology.
project-usage/gitops-workflow.md: new file - the accurate replacement for
'how do I actually deploy something' until the older helmfile-era docs in
this directory get a full rewrite (flagged as stale in CLAUDE.md's new
Documentation Map section rather than rewritten wholesale in this pass -
that's ~12 files, out of scope for this change).
Bitnami stopped publishing versioned image tags in 2025 - only 'latest' and
sha256-pinned digests remain for their free-tier images. Confirmed via
Docker Hub API before writing this fix: no '1.30' tag exists for
bitnami/kubectl, which caused an indefinite ImagePullBackOff (job stuck
'Running' with 0 pods able to start).
Switched to python:3.12-alpine + a stdlib urllib kubectl download, matching
the exact pattern already proven working in
k8s/security/iam/authentik-provision-job.yaml (which hit its own apk
permission problem on this same base image, now fixed the same way in
both places) - avoids depending on any third party's tagging policy.
PreSync hooks run BEFORE an Application's own normal (non-hook) resources
are synced. This Job's ServiceAccount/ClusterRole/RoleBindings are plain
resources in the same Application, so marking the Job PreSync created a
chicken-and-egg deadlock: confirmed live, the Job sat 'Running' for 14
minutes producing zero pods, with job-controller repeatedly logging
'serviceaccount temporal/temporal-db-secret-sync not found' - because that
ServiceAccount hadn't been created yet (it's created during the normal Sync
phase, which comes after PreSync).
Fixed to PostSync. This app (sync-wave 7) still fully completes - including
this hook - before the temporal Application (sync-wave 8) begins, so the
ordering guarantee we need (secret exists before Temporal's pods try to
mount it) is unaffected; only the intra-app hook-vs-normal-resource
ordering was wrong.
Job was crash-looping: 'apk add --no-cache curl' failed with Permission
denied - the container runs as non-root UID 1000 (securityContext.
runAsNonRoot: true), and both apk's working directories and /usr/local/bin
(where curl-downloaded kubectl was being written) are root-owned in the
python:3.12-alpine base image.
Replaced with a pure-Python download via urllib (stdlib, already a
dependency of this Job) writing to /tmp (world-writable) instead - no apk
install needed at all. PATH is extended to include /tmp before invoking the
provisioning script so authentik-provision.py's existing
subprocess.run(['kubectl', ...]) calls resolve it via normal PATH lookup,
no changes needed to the script itself.
Root cause: pinned to temporalio/helm-charts @ 0.74.0, which uses the OLD
flat persistence schema (server.config.persistence.<store>.driver/.sql),
NOT the datastores:-wrapped schema shown in the CURRENT chart's
values/values.postgresql.yaml example (that key was introduced in a later
major version). Our old values.yaml used the datastores: key, which doesn't
exist in 0.74.0 - Helm doesn't validate unknown keys, so it was silently a
no-op. persistence.default.driver / persistence.visibility.driver stayed at
their chart default ("cassandra", with empty hosts: []) the entire time,
regardless of anything nested under datastores:.
Verified before writing this fix: cloned temporalio/helm-charts, checked out
tag temporal-0.74.0 (exact pin), ran +
against our actual values.yaml - confirmed the rendered
schema-setup Job used CASSANDRA_HOST/temporal-cassandra-tool the whole time.
Re-rendered with the corrected flat schema - zero Cassandra references,
correct postgres12 pluginName/connectAddr wired to ddb-cluster-rw.
Also fixed two compounding no-ops found the same way:
- -> real keys are schema.setup.enabled /
schema.update.enabled / schema.createDatabase.enabled (jobs.autoSetup
doesn't exist anywhere in this chart's templates or values.yaml).
- cassandra.enabled was never actually set to false (stayed at chart
default true) - now explicitly false, along with mysql/elasticsearch/
prometheus/grafana (none of which we want).
Password wiring: existingSecret: temporal-db-role + secretKey: password,
pointing at the CNPG-generated Secret - avoids storing the DB password as
plaintext in this values file. Added a new temporal-db-secret-sync
Application (sync-wave 7, one before temporal's wave 8) with a PreSync hook
Job that copies that Secret from the ddb namespace into temporal (Secrets
are namespace-scoped; CNPG creates it in ddb, but Temporal's pods run in
temporal). Deliberately a standalone directory/Application rather than
folded into temporal/'s own kustomization.yaml, which has a The Temporal CLI manages, monitors, and debugs Temporal apps. It lets you run

Use "temporal [command] --help" for more information about a command. transformer that would silently rewrite the copy-job's ddb-scoped
RoleBinding back to temporal (same class of bug just fixed in
k8s/security/iam/kustomization.yaml).
Root cause of the provisioning Job never appearing in-cluster despite being
committed and pushed: k8s/security/iam/kustomization.yaml has an explicit
resources: allowlist (not a plain directory scan) and the new file was never
added to it, so ArgoCD's Kustomize build silently omitted every object in it
- no error, no drift shown, iam-jobs just reported Synced/Healthy against a
manifest set that never included the new Job/ConfigMap/RBAC at all.
Also removed the top-level transformer. It would have
force-rewritten metadata.namespace to iam on every resource in this
kustomization, including authentik-provision-job.yaml's RoleBindings which
deliberately target cicd/argocd/logging/storage (least-privilege access for
the authentik-provisioner ServiceAccount to read/create Secrets in exactly
those namespaces and no others). Every manifest in this directory already
sets its own explicit namespace, so dropping the transformer is a no-op for
the existing key-rotation-cronjob.yaml.

"""
Authentik OAuth provisioning - idempotent, safe to re-run (ArgoCD PostSync hook).
Creates/updates, in order:
1. A custom "groups" OAuth2 scope mapping (Authentik ships openid/email/profile
by default but NOT groups - required for ArgoCD RBAC group mapping and
Grafana's role_attribute_path, both of which read a `groups` claim).
2. Groups: homelab-admins (is_superuser=true), grafana-admins.
3. User "rock": created if missing, always (re-)synced into both groups above.
Password is generated once and only written to the k8s Secret
rock-credentials (iam ns) the first time the user is created - re-runs
never rotate an existing password.
4. OAuth2/OIDC providers + Applications for: grafana, minio, forgejo, argocd.
Client secrets are read from existing k8s Secrets (grafana-oidc, minio-oidc)
if present, or generated once and written out (forgejo-oidc, oidc-secret)
the first time.
5. PolicyBinding of homelab-admins -> every Application above, so "rock" (and
anyone else in that group) has guaranteed access regardless of each app's
default visibility.
Talks to Authentik over the in-cluster Service (authentik-server.iam.svc:80),
authenticating with the bootstrap token. Everything is done with GET-then-
create-or-patch so this can be re-run on every ArgoCD sync without duplicating
or clobbering objects (PostSync hook, not a one-shot Job with hook-delete).
kubectl is used only to read/write the small set of Secrets this script
touches - it shells out rather than using the Python k8s client to keep the
container image to stdlib Python + the kubectl binary, no pip installs.

confirms all 5 RoleBindings land in their correct distinct namespaces
(iam/cicd/argocd/logging/storage) and every resource renders as valid YAML.
Adds k8s/security/iam/authentik-provision-job.yaml - a PostSync hook Job
(reruns every ArgoCD sync via hook-delete-policy: BeforeHookCreation) that
replaces the never-migrated setup_talos_iam.sh / provision_oidc.py workflow
(both referenced helmfile + a Python script that no longer exists in this
repo - OAuth was never actually provisioned since the ArgoCD migration).
Idempotently creates:
- Custom 'groups' OAuth2 scope mapping (Authentik doesn't ship one by
default; required for ArgoCD's RBAC groups claim and Grafana's
role_attribute_path, both of which read a groups claim from the token).
- Groups: homelab-admins (is_superuser), grafana-admins.
- User 'rock', member of both groups above - gets full Authentik superuser
access, ArgoCD role:admin via the existing
RBAC policy in argocd-values.yaml, and
Grafana Admin role via role_attribute_path. Password generated once,
stored in iam/rock-credentials (never rotated on re-run).
- OAuth2 providers + Applications for grafana, minio, forgejo, argocd.
Client secrets read from existing Secrets (grafana-oidc, minio-oidc) or
generated once and written out (forgejo-oidc, argocd's oidc-secret).
- PolicyBinding of homelab-admins -> every Application, guaranteeing rock
access regardless of each app's default visibility.
Also fixes forgejo-values.yaml: oauth2.CLIENT_ID was set but CLIENT_SECRET
was missing entirely (oauth2 login could never have worked). Added via
extraEnv -> GITEA__oauth2__CLIENT_SECRET sourced from the new forgejo-oidc
Secret, since the oauth2: values map can't reference a Secret inline.
RBAC: dedicated ServiceAccount + ClusterRole (secrets get/list/create/update/
patch only) bound via namespace-scoped RoleBindings in iam/cicd/argocd/
logging/storage - the only 5 namespaces this job ever touches, and the only
resource type it ever touches.
NOTE: MinIO's OIDC env vars were removed from minio-tenant.yaml earlier
(blocked IAM init because the provider/app didn't exist yet -> 404 on
discovery). Now that this job creates them, re-adding MinIO's OIDC config is
a safe follow-up in a separate change.
1. prometheus CRD sync failure (OutOfSync, permanently failing):
- helm.skipCrds: true on the prometheus Application - stop ArgoCD from
managing these CRDs through client-side apply (kube-prometheus-stack's
CRDs are large enough that the kubectl.kubernetes.io/last-applied-
configuration annotation exceeds etcd's 262144-byte limit on every sync).
- New prometheus-crds Application: plain git-sourced YAML (extracted via
helm show crds, committed under k8s/platform/monitoring/crds/), synced
with ServerSideApply=true. Chosen over a Helm-sourced 'CRDs only' app
because there's no clean way to ask ArgoCD's Helm source for 'render only
the crds/ directory' - a committed plain-YAML source is unambiguous.
- ServerSideApply=true can't go on the main prometheus Application: it
conflicts with managedNamespaceMetadata's forced namespace apply
('--force cannot be used with --server-side'), hence the split.
2. minio-tenant stuck OutOfSync (blocked 97+ minutes):
- minio-policy-setup PostSync hook Job was NAME:
mc alias set - set a new alias to configuration file
USAGE:

EXAMPLES:
1. Add MinIO service under "myminio" alias. For security reasons turn off bash history momentarily.
$ set +o history
$ mc alias set myminio http://localhost:9000 minio minio123
$ set -o history
2. Add MinIO service under "myminio" alias, to use dns style bucket lookup. For security reasons
turn off bash history momentarily.
$ set +o history
$ mc alias set myminio http://localhost:9000 minio minio123 --api "s3v4" --path "off"
$ set -o history
3. Add Amazon S3 storage service under "mys3" alias. For security reasons turn off bash history momentarily.
$ set +o history
$ mc alias set mys3 https://s3.amazonaws.com \
BKIKJAA5BMMU2RHO6IBB V8f1CwQqAcwo80UEIJEjc5gVQUSSx5ohQ9GSrr12
$ set -o history
4. Add Amazon S3 storage service under "mys3" alias, prompting for keys.
$ mc alias set mys3 https://s3.amazonaws.com --api "s3v4" --path "off"
Enter Access Key: BKIKJAA5BMMU2RHO6IBB
Enter Secret Key: V8f1CwQqAcwo80UEIJEjc5gVQUSSx5ohQ9GSrr12
5. Add Amazon S3 storage service under "mys3" alias using piped keys.
$ set +o history
$ echo -e "BKIKJAA5BMMU2RHO6IBB\nV8f1CwQqAcwo80UEIJEjc5gVQUSSx5ohQ9GSrr12" | \
mc alias set mys3 https://s3.amazonaws.com --api "s3v4" --path "off"
$ set -o history against
http://minio.storage.svc.cluster.local:9000 - stale port. The minio
Service's port now tracks requestAutoCert on the Tenant (443 when
auto-TLS is on, 80 when off - we set it to false earlier), so 9000
doesn't exist on that Service anymore and the job hung in its 'waiting
for minio...' retry loop indefinitely, blocking ArgoCD's sync operation
(PostSync hooks block the sync from completing until they succeed).
- Fixed to use minio-cluster-hl.storage.svc.cluster.local:9000 - the
headless per-pod Service, which always listens on 9000 regardless of
the Tenant's TLS mode, so this can't silently break again the same way.
Our Ingress objects intentionally omit per-rule tls: blocks (single wildcard
cert served via --default-ssl-certificate). nginx-ingress's normal ssl-redirect
setting only forces HTTPS 301 for hosts with an explicit TLS block on their own
Ingress resource - since none of ours do, plain http://*.riotpiao.com requests
were served directly instead of redirected, exposing every client-facing
console (forgejo, authentik, argocd, grafana, vault, etc.) over plaintext HTTP.
force-ssl-redirect forces the redirect globally regardless of per-ingress TLS
block presence. Verified fix works (tested via manual patch then reverted -
confirmed 308 redirects to https:// on forgejo/authentik/argocd) before
committing via GitOps.
Root cause of widespread 'Unknown' sync status / Skipping auto-sync across
almost every Application: CoreDNS rewrites forgejo.riotpiao.com to the nginx
ingress controller service (rewrite name forgejo.riotpiao.com -> ingress-nginx-
controller...), which only listens on 80/443, not 3000. Every git fetch from
argocd-repo-server to the :3000 repoURL was timing out (context deadline
exceeded), so ArgoCD couldn't compare desired vs live state for any app.
Fix: use https://forgejo.riotpiao.com (no port, TLS via nginx + wildcard cert)
consistent with the 'all external endpoints HTTPS' requirement. Verified git
smart-http response 200 on the new URL before committing.
- minio console ingress: minio-console -> minio-cluster-console:9090 (service renamed by operator)
- minio-api ingress: point to minio:9000 (restored once requestAutoCert disabled)
- minio tenant: requestAutoCert: false (MinIO was TLS-only internally, breaking
plain-HTTP clients like Vault's S3 backend - this was the real cause of the
Vault S3 hang)
- argocd ingress: moved from namespace cicd -> argocd (service lives in argocd
namespace; ingress in wrong namespace can never route, was returning 503)
- removed duplicate kmsvc ingress (sqs namespace already has management-service
ingress with proper TLS block for same host/backend)
Audit method: cross-checked every ingress backend.service.{name,port} against
actual Service objects in cluster. Found 3 broken backends out of 15 ingresses.
Wildcard cert was left on letsencrypt-staging; staging root is not
browser-trusted so HTTPS to *.riotpiao.com fails cert validation.
Switch issuerRef to letsencrypt-prod to issue a trusted wildcard.
Adds optional cloudflare_talos_sans (machine.certSANs, talos API :50000) and
cloudflare_apiserver_sans (cluster.apiServer.certSANs, kube-apiserver :6443) per
control-plane node. cp-1 gets cp1.homelab + cp1-talos.homelab; cp-2/cp-3 get
their cpN-talos.homelab. Values set in gitignored tfvars.
authentik/temporal DB users+databases were never provisioned (old helmfile hook
gone; db-init-job only made schemas in shared app DB). Adds managed.roles
(authentik/temporal login roles, passwords from basic-auth secrets) + Database CRs
(dedicated DBs owned by each role). Role secrets applied out-of-band (SOPS), not in
kustomize resources so data-schemas app doesn't choke on ciphertext.
Loki keys are under .loki.storage.s3 not .loki.s3 (returned null). Emit a separate
authentik-secrets Secret (not 'authentik', which the Helm chart owns) and merge it
via envFrom on server/worker/migrate. Remove discover fileName (caused MatchRepository
timeouts; app names the plugin explicitly).
Correct CMP setup (prior attempt used unsupported config): repoServer.initContainers
fetches sops v3.9.0 + yq v4.44.3 into a shared volume; repoServer.extraContainers
runs argocd-cmp-server with plugin.yaml from the sops-cmp-plugin ConfigMap, age key
from sops-age Secret. Plugin emits authentik/loki-s3-creds/grafana-admin/grafana-oidc
Secrets from decrypted enc files. sops-secrets Application (wave 0) uses the plugin at
repo root. Unblocks authentik/loki/grafana which were Degraded on missing secrets.
Substrate had no owner since Terraform was deleted (Pure GitOps). Adds 5 wave-0/1
Applications: cert-manager v1.21.0 (installCRDs, CP tolerations), ingress-nginx
4.15.1 (LB 192.168.1.160), reloader 2.2.14 at wave 0; LE ClusterIssuers +
*.riotpiao.com wildcard cert at wave 1 (DNS-01 via Cloudflare). Adds 3 chart
repos to AppProject sourceRepos and SOPS-encrypted cloudflare-api-token secret.
Cert starts on letsencrypt-staging; flip to prod after clean issue.
Switch Tenant from credsSecret to configuration field (v5 pods read config.env
shell exports); pin image to RELEASE.2025-07-23 (the old 2024-06 tag was pulled
from Docker Hub, ErrImagePull); drop prometheusOperator:true (made operator fail
reconcile hunting Prometheus in ns default). MinIO now serves S3, 4/4 drives OK,
root auth works. Operator's cosmetic 'empty tenant credentials' health-log is
harmless (documented inline).
Old Tenant used unknown v2 fields (pools[].size/storageClass, spec.console/metrics/ingress)
and referenced nonexistent minio.min.io/v1alpha1 Bucket/Policy/User kinds, so the app
never synced. Rewrites to valid v2: single erasure-coded pool (4 vols) pinned to
talos-cp-1/az-a (only schedulable+Longhorn node per 3-CP topology), spec.buckets +
spec.users declarative provisioning, prometheusOperator ServiceMonitor, features.domains.
Drops hand-rolled minio-service (operator owns it), dead multi-site replication job,
and legacy alias. Adds mc-based PostSync job for the ollama scoped policy, and
SOPS-encrypted minio-creds/oidc/user secrets for IaC record.
The operator chart moved to https://operator.min.io/; https://charts.min.io/ only
ships the standalone minio chart, causing 'chart operator not found in index'.
Pin to 5.0.18 (v5.x schema matches minio-operator-values.yaml operator.image.tag v5.0.0);
targetRevision '*' was fragile. Unblocks minio-tenant (needs operator CRDs).
Reverts complex CMP plugin setup (helm chart doesn't support repoServer.extraContainers).
Instead: sops-secrets Application uses directory source (no plugin), emits placeholder
README. Manually-created Secrets (grafana-admin) live in target namespaces.
Full CMP plugin work deferred to future stage. Grafana values still wired to
admin.existingSecret (no-op until Secret exists, which it now does).
This unblocks cluster deployment without waiting for ArgoCD CMP plumbing.
- Create SOPS-encrypted cloudflared-secrets.enc.yaml with tunnel token
- Add Cloudflare vars to .env.example (CLOUDFLARE_CONNECTOR_TOKEN, ACCOUNT_ID, TUNNEL_ID, API_TOKEN)
- Document Phase 0 cloudflared-token Secret creation in BOOTSTRAP.md (manual step until CMP plugin wires it)
- Note: Cloudflare-side TCP routing (cp1.homelab -> 192.168.1.213:6443, etc.) must be configured manually in Zero Trust dashboard
Tunnel already deployed as ArgoCD Application in k8s/argocd/apps/60-applications.yaml (wave 8); this closes the missing Secret gap and documents the bootstrap path.
Consolidate three separate Forgejo Actions (argocd-sync, security-scan, validate-k8s) into single cluster-ci workflow for cleaner CI/CD pipeline with proper job sequencing and reduced auth overhead.
Add Terraform configuration for Talos cluster machine configs:
- Provider setup for Talos
- Centralized variables for CP and worker configs
- Template-based config generation for controlplane.yaml and worker-*.yaml
- Sensitive data separated in terraform.tfvars (gitignored)
- Local state tracking for infrastructure
Use CI_RUNNER and CI_RUNNER_SECRET for repo clone authentication.
Embed credentials in git clone URL: https://user:token@host/repo.git
Removes dependency on GITHUB_TOKEN (GitHub-specific) and improves Forgejo compatibility.
Recreate ingress-nginx-controller LoadBalancer service that was deleted.
Add to k8s/bootstrap/ingress/ kustomization for ArgoCD management.
LoadBalancer assigned IP: 192.168.1.160 (via MetalLB)
ArgoCD now accessible via: https://192.168.1.160/ (or update DNS)
Add MinIO Policies and Users via CRD alongside Buckets.
Resources now declarative:
- Bucket: riotpiao-models (versioning enabled)
- Policy: policy-ollama (scoped bucket access)
- User: user-ollama (service account for Ollama/LLM)
Access keys can be overridden via SOPS or kustomize overlays.
All MinIO resource creation now git-tracked and version controlled.
- main.tf: remove kubeconfig_path local (no longer used with direct auth)
- providers.tf: wrap file() with try() to handle plan-time on non-pod systems
try() allows terraform plan to work locally; at runtime in pod, files exist and are used.
