Keep local/default terragrunt runs pointed at the real public URL;
set the goauthentik#954 ClusterIP workaround via TF_VAR_authentik_url
in the CI environment blocks instead of as a terragrunt input.
Parameterise the authentik provider url as var.authentik_url (default:
the environment's public URL) and override it for
identity.k8s.syd1.au.unkin.net to
http://authentik-server.authentik.svc.cluster.local. Combined with
sessionAffinity: ClientIP on the Service, in-cluster CI runs pin to a
single server replica, eliminating the cross-replica read-back race
(goauthentik/terraform-provider-authentik#954).
Introduce a user -> role -> [permissions] model for app access and roles,
managed declaratively.
- Permission groups (akP-<app>-<access>) under config/permissions/: atomic units,
each names the application it grants access to.
- Role groups (akR-<role>) under config/roles/: what users are assigned to;
each nests permission groups via parents (akR-global-admin -> all *-admin,
akR-standard-user -> all *-user). Split into a separate authentik_group
resource so roles can reference permission ids without self-reference.
- Policy bindings gate each application to its permission groups (and, via
child->parent membership propagation, the roles that nest them).
- Hierarchical `groups` scope mapping: walks user groups up through .parents so
the OIDC claim includes inherited permission groups (works around
goauthentik/authentik#15579). Inert until a provider requests the `groups`
scope, so no behaviour change to existing apps until they opt in.
Validated with `tofu validate`.
The CI VAULT_TOKEN (short-lived k8s-auth role token) can't create child
tokens, so the vault provider failed with 'failed to create limited child
token: permission denied'. Use the token directly.
The module's versions.tf and the root.hcl-generated backend.tf both
declared required_providers, which OpenTofu rejects ("A module may have
only one required providers configuration"), so terragrunt init/plan
failed. Keep them in the module's versions.tf (authentik + vault) and
generate only the backend + provider blocks.
Adds an OIDC provider + application so the in-cluster Grafana
(grafana.k8s.syd1.au.unkin.net) can authenticate users against Authentik.
Extends the oauth2 module so provider config stays declarative and
secret-free:
- Resolve authorization/invalidation flows by slug (data.authentik_flow)
and scope mappings by managed identifier
(data.authentik_property_mapping_provider_scope).
- Read client_secret from Vault kv-v2 (data.vault_kv_secret_v2) instead of
committing it; adds the hashicorp/vault provider (auth via VAULT_ADDR/
VAULT_TOKEN from the Makefile).
- Support allowed_redirect_uris on the oauth2 provider.
config/providers_oauth2/grafana.yaml wires client_id `grafana`, the
openid/email/profile scopes, the login/generic_oauth redirect URI, and
points client_secret at kv/kubernetes/namespace/grafana/default/oauth-credentials.
- Terraform module for groups, SAML/OAuth2/LDAP providers, applications, and LDAP outposts
- Data-driven YAML config with Terragrunt config loader
- Environment: identity.unkin.net with Consul backend
- Provider: goauthentik/authentik 2026.5.0
- Woodpecker CI pipelines (pre-commit, plan, apply)
- Makefile with Vault AppRole and K8s auth support
