## Why Vault's kubernetes secret engine will mint scoped tokens for a static \`agent-dns\` service account instead of generating cluster-wide RBAC, so agent DNS access is confined to exactly the bind namespaces. This is the GitOps half of the terraform-vault agent-dns role rework (PR unkin/terraform-vault#109). Ordering: this must sync before the Vault \`agent-dns\` creds are usable — Vault mints tokens for an SA that must already exist. ## How - Add ServiceAccount \`agent-dns\` + ClusterRole \`agent-dns\` (definition only, no ClusterRoleBinding) in \`bind-system\`: full verbs on \`bind.unkin.net\` CRDs, get/list/watch pods/services/configmaps/events, get pods/log. - Add RoleBinding \`agent-dns\` in each of \`bind-system\`, \`bind-internal\`, \`bind-external\`, \`externaldns\`, binding the SA to the ClusterRole in that namespace — confining all access (reads included) to those four namespaces. Whitelist note: the platform AppProject already permits ClusterRole/ClusterRoleBinding and all four namespace destinations, so no project change is needed. https://claude.ai/code/session_01JUoARVdmhxKQHyyyp1pxeT --------- Co-authored-by: Ben Vincent <neotheo@gmail.com> Reviewed-on: #332 Co-authored-by: Ben Vincent <ben@unkin.net> Co-committed-by: Ben Vincent <ben@unkin.net>
