Scooby HuskyandClaude Sonnet 5 bce3861083 GitLab cross-site replication Phase 2b: enable Gitaly + workhorse TLS
Per the approved plan (Istio federation scoped separately, current
NodePort/PeerAuth/cert-manager pattern continues for these 2 remaining
links). Real Let's Encrypt certs (not self-signed) via the same DNS-01
ClusterIssuer used everywhere else - both sites already trust Let's
Encrypt's public CA, no custom CA distribution needed.

- global.gitaly.tls.enabled: adds tls_listen_addr (8076) alongside the
  existing plaintext listener (8075, stays for in-cluster traffic
  that doesn't need it). Requires
  global.praefect.virtualStorages[0].tlsSecretName (chart's own NOTES.txt
  validation rejects the render without it, confirmed live).
- global.workhorse.tls.enabled + global.workhorse.host: Gitaly's [gitlab]
  url (internal-API callback for gitlab-shell hooks) switches from an
  unpublishable *.svc.cluster.local name to a real floating hostname
  (gitlab-internal-api.ha.huskypup.net) that Let's Encrypt CAN certify -
  confirmed live this replaces the plaintext [[listeners]] block with
  [listeners.tls] on the SAME port (8181), not a second port like Gitaly.
- praefect-ha-configmap.yaml (the manually-patched live config) updated
  to tls:// + floating hostnames for all 3 home nodes, so home's own
  Praefect uses the identical addresses it'll hand the VPS as peer
  addresses once Phase 2b's 4th node lands.
- New CoreDNS rewrite for gitlab-internal-api.ha.huskypup.net (same
  local-rewrite pattern as pg-*/gitaly-* already have).

Sequencing note: applying live - Certificates must issue before the
TLS-enabling values land, or Gitaly/webservice pods fail to start
(missing secret for their init container's cert copy).

Scooby HuskyandClaude Sonnet 5 6cf1d89278 GitLab cross-site replication Phase 2a (corrected): ignoreDifferences approach
The CONFIG_TEMPLATE_DIRECTORY redirect from the previous commit doesn't
work - confirmed live that extraVolumes is a dead values key for the
Praefect subchart specifically (its statefulset.yaml never calls the
gitlab.extraVolumes helper in its volumes: list, only volumeMounts
calls the corresponding helper - a real chart limitation, not a config
mistake). A dangling volumeMount with no matching volume would have
failed to schedule.

Real fix: ignoreDifferences on ConfigMap gitlab-praefect's data field
(argocd-apps/apps/gitlab.yaml) lets Helm create the object normally
while ArgoCD stops reconciling its content afterward - the actual
config gets kubectl-patched onto the live object directly.
praefect-ha-configmap.yaml is now a git-tracked reference/documentation
copy (deployed under its own harmless name) rather than something
Helm/ArgoCD wires in on its own.

Scooby HuskyandClaude Sonnet 5 38dad209e3 GitLab cross-site replication Phase 2a: Praefect config override mechanism
Proves the CONFIG_TEMPLATE_DIRECTORY redirect works before Phase 2b
adds any actual cross-site dependency. Content is byte-identical to
the chart's current rendering (confirmed live) - this commit only
tests the override plumbing itself: a new ConfigMap
(praefect-ha-configmap.yaml) mounted at a different path than the
chart's own /etc/gitaly/templates (can't reuse that path/volume name -
Kubernetes rejects duplicates), with CONFIG_TEMPLATE_DIRECTORY
overridden via extraEnv to point at it instead (last-wins env
semantics, confirmed Kubernetes-documented behavior).

Also removes gitlab.praefect.virtualStorages - confirmed live dead
config, global.praefect.virtualStorages is what the chart's template
actually reads.

Scooby HuskyandClaude Sonnet 5 1ab292e185 Fix GitLab Authentik SSO: restore providers list, populate real provider key
GITLAB_OMNIBUS_CONFIG (gitlab_rails['omniauth_providers'] = [...]) is
an omnibus-Docker-image-only convention. This chart's CNG webservice
image never processes it - confirmed via gitlab/charts/gitlab/
templates/_omniauth.tpl, which only reads
global.appConfig.omniauth.providers (a list of {secret,key} refs, each
pointing at a Secret key holding a whole YAML-encoded provider block
loaded via Ruby's YAML.load_file). So GITLAB_OMNIBUS_CONFIG was always
a silent no-op on both home and VPS - neither ever actually had SSO
configured despite gitlab-oidc-secret existing and looking correct.

Yesterday's fix for 'FailedMount: references non-existent secret key:
provider' removed the providers: list entirely instead of populating
that key - stopped the crash, but also silently deleted the only real
OIDC config path on both sites (no error, login page just lost its SSO
button). This restores providers: on both, and gitlab-oidc-secret's
ExternalSecret template now actually renders a provider key containing
a real YAML provider block (with the templated client_id/secret
substituted in), matching what _omniauth.tpl expects.

Scooby HuskyandClaude Sonnet 5 989d42dd50 Fix GitLab OIDC secret FailedMount blocking webservice/sidekiq startup
Real bug affecting both home and VPS GitLab, found live diagnosing why
VPS's webservice pod was stuck at Init:0/3 for 74+ minutes (surfacing as
404s - nothing was ever actually serving):

global.appConfig.omniauth.providers: [{secret: gitlab-oidc-secret, key:
provider}] requires that secret to have a 'provider' key (a full YAML
omniauth provider config) - gitlab-oidc-secret never has one, only
GITLAB_OIDC_CLIENT_ID/SECRET, which get consumed via extraEnvFrom +
GITLAB_OMNIBUS_CONFIG's gitlab_rails['omniauth_providers'] instead (the
actual, complete mechanism already configuring OIDC - this providers:
list was always redundant). Removed it from both values.yaml files.

Home's GitLab has run fine so far because Kubernetes doesn't re-validate
already-mounted volumes when a referenced Secret's shape changes -
webservice/sidekiq there just haven't restarted since gitlab-oidc-secret
was last (if ever) in a shape with that key. VPS's identical values
shape hit it immediately on first pod creation. This was a live landmine
for home too - fixed before it could bite on a future restart.

Also: global.kas.enabled: false added to the VPS values (gitlab.kas.enabled
alone doesn't stop KAS pods - found live, separate toggle).

Reduce replicas to 1 for workloads that don't need HA in a homelab:
- Prometheus 2→1, Alertmanager 2→1 (~4.4GB RAM saved)
- cert-manager 3→1
- GitLab: registry 2→1, kas 2→1, sidekiq 2→1, praefect 2→1,
  pgbouncer-ro 3→1
- Guacamole + guacd 2→1
- Kiali 2→1, ArgoCD server 2→1
- Kyverno background-controller 2→1
- Scylla operator 2→1
- ext-authz-proxy 2→1, netbird-cluster-router 2→1

Kept multi-replica: coredns, envoy-gateway, kyverno admission,
vault, argocd-repo-server, gitlab-webservice, istiod, rook-ceph CSI.

Scooby HuskyandClaude Opus 4.6 fa23e5084c Reduce GitLab latency: increase Gitaly CPU limit and Puma workers
Gitaly CPU limit was 250m causing throttling on git operations (485ms
p99 to webservice). Increased to 1 core with 100m request. Also added
workerProcesses: 3 to webservice for better request concurrency
(was default 2).

Scooby HuskyandClaude Opus 4.6 d304bd257d Increase GitLab webservice resources to fix slow initial response
Webservice was at 94% memory (1875Mi/2Gi) with only 50m CPU request,
causing CPU throttling and slow first requests after idle periods.
