- Enable size-based TSDB retention (45GB) to clean up old blocks
(including 2021-era blocks with failed compaction)
- Increase monitoring namespace quota from 64/128Gi to 80/160Gi
CPU/memory limits to allow Grafana rolling updates
Fixes HA mobile app 403 when embedding Grafana dashboards - the webview
blocks third-party cookies needed by Authentik forward auth. Grafana
already has anonymous Viewer access enabled, so forward auth is not
needed. Also adds grafana_admin_password variable and explicit resource
limits to prevent ResourceQuota issues during rolling updates.
Four layers of noisy-neighbor protection using existing tier system:
- PriorityClasses (tier-0-core through tier-4-aux)
- LimitRange defaults auto-generated per namespace tier
- ResourceQuotas auto-generated per namespace tier
- PriorityClassName injection on pods via Kyverno mutate
Custom quota overrides for monitoring and crowdsec namespaces
which exceed the default tier quotas.
- Remove nginx-specific ingress variables (use_proxy_protocol, proxy_timeout, additional_configuration_snippet)
- Update ingress annotations to use Traefik middleware CRDs
- Delete nginx-ingress module (replaced by traefik)
- Add new traefik middleware.tf for shared middleware definitions
- Update service modules to work with new ingress_factory interface
