authentik_provider_oauth2.allowed_redirect_uris is list(map(string)) and the
API always stores a redirect_uri_type key on each entry. The module only set
matching_mode and url, so every plan showed the Grafana provider being updated
in-place (state map had 3 keys, config map had 2) and never converged.
Add redirect_uri_type to the redirect_uris object, defaulting to
"authorization". `terragrunt plan` now reports no changes.
Adding the first managed group (argocd-admins) exposed a dormant bug: the
groups resource resolved `parents` by indexing authentik_group.this itself,
which OpenTofu rejects as a self-referential block. config/groups/ had been
empty, so `tofu plan` never hit it before.
Pass `parents` through as literal group PKs instead (the resource cannot
reference itself, so parent-by-map-key was never viable). Plan is clean:
3 to add (argocd provider, application, argocd-admins group).
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 authentik provider needs a token but nothing supplied it, so plan
failed with 'No value for required variable authentik_token'. Source it
from Vault in vault_env like the consul creds, from the dedicated
terraform-service path kv/service/terraform/authentik (field: token),
overridable via AUTHENTIK_TOKEN_KV_* vars.
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.
