## Why Agentic workloads currently need cluster-admin/root kubeconfig contexts to do routine per-domain work. This adds domain-scoped, Vault-issued kubernetes credentials plus an `agents` AppRole so agents get least-privilege access instead of escalating. ## Changes - Add `kubernetes_secret_backend_role` configs `agent-dhcp`, `agent-dns`, `agent-certs`, `agent-storage` (au/syd1): - **agent-dhcp** (Role, ns `dhcp-system`): full verbs on `kea.unkin.net` CRDs; get/list/watch pods/services/configmaps/events + pods/log. - **agent-dns** (`service_account_name` mode): mints tokens for the static `agent-dns` SA (argocd-apps#332) whose per-namespace RoleBindings confine access to bind-system/bind-internal/bind-external/externaldns. `allowed_kubernetes_namespaces: [bind-system]` (the SA's namespace). - **agent-certs** (Role, ns `cert-manager`): full verbs on `cert-manager.io` + `acme.cert-manager.io` (closes the orders/challenges debugging gap); get/list/watch/delete secrets; get/list/watch pods + pods/log. Secret delete confined to `cert-manager`. - **agent-storage** (Role, ns `cephrgw-system`): full verbs on `ceph.unkin.net` CRDs (buckets/bucketaccesses/objectstoreusers); get/list/watch pods + pods/log. - Extend the `kubernetes_secret_backend_role` module with an optional `service_account_name`; when set, `generated_role_rules`/`kubernetes_role_type` are omitted (the SA's own bindings supply RBAC). - Add creds policies for each role, bound to the `kubernetes_au_syd1_cluster_operator` ldap group (human kubectl use) and the `agents` AppRole (programmatic use). - Add the `agents` AppRole (mirrors the certmanager approle schema): `bind_secret_id: false` (role_id-only login), `token_bound_cidrs: [10.10.12.200/32]` (agent workstation wg0 addr), deterministic role_id, 1h/4h TTLs. - Add `policies/kv/kubernetes/agents.yaml` granting the AppRole create/read/update/list on `kv/data/kubernetes/*` + read/list on `kv/metadata/kubernetes/*` (no delete). ## Ordering argocd-apps#332 (the `agent-dns` SA + ClusterRole + per-namespace RoleBindings) must sync **before** the `agent-dns` creds here are usable — Vault mints tokens for a service account that must already exist. https://claude.ai/code/session_01JUoARVdmhxKQHyyyp1pxeT Reviewed-on: #109 Co-authored-by: Ben Vincent <ben@unkin.net> Co-committed-by: Ben Vincent <ben@unkin.net>
