Vault/OpenBao secrets engine managing Rancher API tokens via the public
tokens.ext.cattle.io API.
- config: Rancher connection (URL + TLS)
- service-accounts/<name>: seeded root tokens, auto-rotated before Rancher's
TTL cap via a PeriodicFunc (default 45d rotation, 90d token TTL); the current
token mints its own replacement. Manual /rotate endpoint too.
- roles/<name>: mint policy referencing a service account; cluster_name + TTL
scoping (Rancher tokens inherit the seeding user's RBAC).
- creds/<role>: dynamic, lease-bound tokens deleted from Rancher on revoke.
Ports the bind-tsig Woodpecker RPM release, nfpm packaging, and a mock-Rancher
e2e (Vault + OpenBao). Unit tests cover the full lifecycle.
