IaC 面 (infra/) 与控制面 (server/internal/provision) 双产出，落地 doc/04 §4 「节点是牲口」弹性拓扑与 make-before-break 一键更换。 server/internal/provision: - CloudAdapter 适配层 + Registry（首发 vultr 消耗品池 / hetzner 精品池各一）； 厂商凭证仅从 PROVISION_<VENDOR>_* env 注入，不入库不入 git。 - ProvisionService：CreateNode(幂等键重放不重复开机)、DestroyNode(幂等)、 RotateIP(换 IP 不换机 + version bump)、ListProviders。 - Replace 一键更换：先建后拆，新机 up 先于旧机 draining（容量不下降）， replacement_uuid 幂等键 + replacements 表分步记录，崩溃可续跑不重复。 - RotatePool：池内滚动轮换，并发度 1–2。 - cmd/nodectl CLI：create/destroy/rotate-ip/replace/rotate-pool/providers。 - 单测（mock 厂商 API + 内存 Store）：幂等重放、make-before-break 时序断言、 开机失败/探活超时→destroyed+失败计数+告警钩子、崩溃续跑、RotatePool。 infra/: - terraform/：探针机 + 控制面基线模块化（probe / control-plane）+ README， 低频基线进 state，节点不进 Terraform。 - cloud-init/node.yaml.tmpl：节点引导模板（注入一次性 bootstrap token，task #5）。 - identity-isolation.md：身份隔离登记表（doc/06 §2 红线，无任何凭证）。 migrations/000008：nodes 增 provider_instance_id/elastic_ip_id、node_events 增 ip_rotated、provision_idempotency / replacements 表（附加式，不动现网）。 红线：仅面向新厂商池，绝不纳管现网生产 EC2(deploy/ marzban)。 Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

# Module: `control-plane`
|
|
|
|
Provisions the **control-plane baseline host** (API + MySQL + Redis), doc/04 §5.2.
|
|
|
|
Key properties:
|
|
|
|
- Deployed on a **stable cloud unrelated to the data-plane node vendors**. Nodes
|
|
can all be destroyed without affecting the control plane, and vice-versa. The
|
|
control plane carries **no proxy traffic**.
|
|
- `prevent_destroy = true` — it holds the user DB; it is never recreated
|
|
implicitly. Application bring-up (containers, migrations) is done by the server
|
|
deploy pipeline, not Terraform.
|
|
- Admin/SSH surface is **never on the open internet** (doc/06 §2): inbound is
|
|
locked to `allowlist_cidrs`; the public API sits behind a CDN/proxy terminated
|
|
elsewhere.
|
|
|
|
Disabled by default in the root module (`control_plane_enabled = false`) because
|
|
it changes rarely.
