A per-tenant traces backend costs every tenant its own VictoriaTraces stack. A tenant can now send new spans to one shared store in tenant-root instead, switched on by _namespace.tracingCentral, which the tenant chart publishes and the apps API does not let an application set. tenant-root decides whether it hosts that store, with tracingCentralHost next to a cluster-mode store named generic. VictoriaTraces takes the tenant account from request headers and does no authorization of its own, so other tenants reach the store only through a vmauth in tenant-root; tenant-root itself, with whoever it admits to its Grafana, stays inside the trust boundary. Each central tenant gets a VMUser that pins an account derived from its namespace name and UID for both writes and reads and caps its requests in flight, which the collector's two export senders stay under; its collector exports and its Grafana reads with credentials the chart generates and keeps, and vmauth overrides any account a client sends. The chart owns those credentials because the operator publishes a VMUser's own Secret only once a VMAuth selects it; the collector rolls when they change, since it reads them at start. The vmauth internal routes, whose /metrics names every tenant's user, are served on a port tenants cannot reach, and the vmauth is sized by a VPA, spread across nodes under a disruption budget, has a WorkloadMonitor like the other monitoring workloads, and may reach the apiserver, where its config-reloader reads its config Secret. Renders refuse the states in which spans would be dropped with every object Ready: a central tenant while tenant-root hosts nothing, tenant-root dropping the hosting while central tenants remain, and the host flag without a store to host. Each refusal reads the other side at render time, so a concurrent opt-in and stop-hosting can pass both; the values text names that race and its recovery. At run time tenant-root's release is not Ready while the vmauth has failed. Only the collector's export moves: local stores the tenant still lists keep rendering with their datasources, because the switch belongs to the parent tenant and the stores to this one, and the one-store limit of the collector holds in both modes, since turning central off makes it export locally again. tenant-root never counts as central.

## OIDC authentication for the Grafana instance.
|
|
##
|
|
## Identity mode picks the auth source for `[auth.generic_oauth]`:
|
|
## None no OIDC; login form + admin_user/admin_password Secret
|
|
## stay the only auth path (default).
|
|
## System trust the platform Keycloak realm (`cozy` by default) via a
|
|
## per-instance confidential client and audience binding.
|
|
## Requires the platform-level authentication.oidc.enabled
|
|
## flag; the chart hard-fails the render otherwise.
|
|
## CustomConfig trust a tenant-supplied issuer directly (BYO IdP).
|
|
## Exactly one of `customConfig.config` (inline) or
|
|
## `customConfig.secretRef.name` (existing Secret) must be
|
|
## set — the chart fails the render otherwise. `cozy` is
|
|
## not in the path in this mode.
|
|
##
|
|
## Authorization is app-side: `users` is reconciled into Grafana org
|
|
## membership/roles by a chart-owned post-install/post-upgrade Job.
|
|
## Users not listed here get nothing when they log in — no default org
|
|
## role from group mapping.
|
|
##
|
|
## The admin_user / admin_password Secret stays a documented break-glass
|
|
## path regardless of mode.
|
|
oidc:
|
|
mode: "None"

## CustomConfig payload — consumed only when `mode: CustomConfig`.
|
|
## Exactly one of `config` or `secretRef.name` MUST be set.
|
|
customConfig:
|
|
## Inline map of grafana.ini `[auth.generic_oauth]` keys. Any key
|
|
## accepted by Grafana's generic_oauth provider is valid; typical
|
|
## keys are `enabled: "true"`, `client_id`, `client_secret`,
|
|
## `auth_url`, `token_url`, `api_url`, `scopes`. Grafana defaults
|
|
## `enabled: false`, so an inline map without an explicit
|
|
## `enabled: "true"` is inert — remember to set it.
|
|
##
|
|
## The chart merges TWO chart-forced settings on top of this map so
|
|
## the users-Job contract holds:
|
|
## * `skip_org_role_sync: "true"` (login never overwrites the
|
|
## Job's org-role assignments);
|
|
## * `oauth_allow_insecure_email_lookup: "true"` (OIDC identity
|
|
## binds to the pre-provisioned local account by email).
|
|
## These two keys cannot be overridden — set them explicitly here
|
|
## and the chart still wins. `role_attribute_path` would be dead
|
|
## config; the Job manages roles.
|
|
##
|
|
## Mutually exclusive with `customConfig.secretRef.name`.
|
|
config: {}
|
|
## Reference to an operator-managed Secret carrying a ready-made
|
|
## `[auth.generic_oauth]` ini fragment in the `auth.ini` key. The
|
|
## chart mounts it and Grafana loads it via
|
|
## `GF_PATHS_CUSTOM_INI`. Mutually exclusive with
|
|
## `customConfig.config`.
|
|
##
|
|
## IMPORTANT — users-map is NOT supported in this branch: the
|
|
## chart cannot inject `skip_org_role_sync=true` /
|
|
## `oauth_allow_insecure_email_lookup=true` into a Secret-mounted
|
|
## ini fragment, so the users-Job's role assignments would be
|
|
## silently overwritten on the next login. Either use
|
|
## `customConfig.config` (inline) and let the chart merge the two
|
|
## settings, or leave `spec.oidc.users` empty and manage
|
|
## authorization inside the mounted ini fragment yourself. The
|
|
## chart hard-fails render when both `secretRef.name` and non-empty
|
|
## `users` are set.

## Users granted access to this Grafana instance's org. Each entry

## produces one pre-provisioned Grafana account (matched to the OIDC

|
|
## `Main Org.`. Empty by default — no OIDC user gets any role until
|
|
## an operator lists them here.
