 # terraform-provider-ranchervaultsecret
 
-Terraform provider for the Vault/OpenBao Rancher token secrets engine (ranchervaultsecret)
+Terraform provider for the [vault-plugin-secrets-rancher](https://git.unkin.net/unkin/vault-plugin-secrets-rancher)
+secrets engine. It manages the engine's configuration on HashiCorp Vault or
+OpenBao — mounting it, seeding auto-rotated service-account tokens, and defining
+token-minting roles.
+
+The provider's source address is `git.unkin.net/unkin/ranchervaultsecret`; its
+resources are prefixed `rancher_` (declare it under the local name `rancher` in
+`required_providers`).
+
+## Resources
+
+| Resource | Manages |
+|----------|---------|
+| `rancher_secret_backend` | Mounts the engine and writes `config` (Rancher URL, CA, TLS). |
+| `rancher_secret_backend_service_account` | A seeded, auto-rotated Rancher token (`token`, `token_ttl`, `rotation_period`). |
+| `rancher_secret_backend_role` | A minting role (`service_account`, `cluster_name`, `ttl`, `max_ttl`, `description`). |
+
+## Example
+
+```hcl
+provider "rancher" {} # address/token from VAULT_ADDR / VAULT_TOKEN
+
+resource "rancher_secret_backend" "rancher" {
+  path        = "rancher"
+  rancher_url = "https://rancher.example.com"
+  ca_cert     = file("rancher-ca.pem")
+}
+
+resource "rancher_secret_backend_service_account" "admin" {
+  backend         = rancher_secret_backend.rancher.path
+  name            = "admin"
+  token           = var.rancher_seed_token
+  token_ttl       = 90 * 24 * 3600
+  rotation_period = 45 * 24 * 3600
+}
+
+resource "rancher_secret_backend_role" "ci" {
+  backend         = rancher_secret_backend.rancher.path
+  name            = "ci"
+  service_account = rancher_secret_backend_service_account.admin.name
+  cluster_name    = "c-m-abc123"
+  ttl             = 3600
+  max_ttl         = 28800
+}
+```
+
+Then mint a token: `vault read rancher/creds/ci`.
+
+## Development
+
+```sh
+make build      # build the provider binary
+make install    # install into ~/.terraform.d/plugins for local dev_overrides
+make test       # unit tests
+make e2e        # apply real terraform against Vault + the plugin + mock Rancher
+make package    # zip for the artifactapi terraform registry
+```
+
+Releases are tag-driven (`make patch|minor|major`): a Woodpecker pipeline zips
+the provider and uploads it to the internal artifactapi terraform registry,
+installable via `source = "git.unkin.net/unkin/ranchervaultsecret"`.
