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.

# Builds the plugin, brings up a mock Rancher ext.cattle.io API plus both Vault
|
|
# and OpenBao, then drives the identical lifecycle against each engine to prove
|
|
# the same binary works on both:
|
|
# configure -> service-account (seed) -> rotate -> role -> creds -> revoke.
|
|
#
|
|
# Select engines with ENGINES (default "vault openbao"), e.g. ENGINES=openbao.
