A Terraform/OpenTofu provider that manages the arrstack dynamic secrets engine (vault-plugin-secrets-arrstack) on HashiCorp Vault or OpenBao, so the engine's mount, config, and roles can be driven declaratively (e.g. from terraform-vault). The engine mints short-lived arrproxy API keys scoped to the arr apps (Sonarr, Radarr, Prowlarr).

Source address: artifactapi.k8s.syd1.au.unkin.net/terraform-unkin/vault-secrets-arrstack (declare it under the local name arrstack, so its resources are arrstack_*).

Resources

Resource	Manages
`arrstack_secret_backend`	Mounts the engine at a path and writes its `config` (arrproxy base URL, request timeout, seeded admin token, optional CA cert).
`arrstack_secret_backend_role`	A role: `apps` (subset of sonarr/radarr/prowlarr), `ttl`, `max_ttl`.

Usage

terraform {
  required_providers {
    arrstack = {
      source  = "artifactapi.k8s.syd1.au.unkin.net/terraform-unkin/vault-secrets-arrstack"
      version = "0.1.0"
    }
  }
}

provider "arrstack" {
  # address / token fall back to VAULT_ADDR / VAULT_TOKEN.
}

resource "arrstack_secret_backend" "arrstack" {
  path        = "arrstack"
  base_url    = "https://arrstack.unkin.net"
  admin_token = var.arrproxy_admin_token
}

resource "arrstack_secret_backend_role" "all" {
  backend = arrstack_secret_backend.arrstack.path
  name    = "all"
  apps    = ["sonarr", "radarr", "prowlarr"]
  ttl     = 60
  max_ttl = 86400
}

Notes

admin_token is write-only: Vault never returns it, so it is preserved in Terraform state and does not show drift. ca_cert is likewise write-only and preserved; omit it to use the system trust store.
Writing config makes the engine authenticate against arrproxy as an admin, so a bad URL or token fails the apply.
apps is required; entries must be a subset of sonarr, radarr, prowlarr.

Import

terraform import arrstack_secret_backend.arrstack arrstack
terraform import arrstack_secret_backend_role.all arrstack/roles/all

Development

make build      # build the provider binary
make install    # install into ~/.terraform.d/plugins for local use
make test       # unit tests (race)
make package    # build the release zip

Releases are tag-driven (make patch|minor|major): a Woodpecker pipeline builds terraform-provider-vault-secrets-arrstack_<version>_linux_amd64.zip and PUTs it to the artifactapi terraform registry (.../api/v2/remotes/terraform-unkin/files/terraform-unkin/vault-secrets-arrstack/<file>), which signs it server-side. Install it via the bare source address above.
