# Sprint 3 SSH_COMMAND 指揮權鏈 Implementation Plan
|
||
|
||
> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
|
||
|
||
**Goal:** 讓 AWOOOI AutoRepair 透過 URI scheme 路由（`openclaw://`、`ansible://`、`ssh://`）執行主機層修復，並補齊安全（known_hosts、ConfigMap 白名單、Shell Injection 防護）、可觀測性（AuditLog、Langfuse Trace）、架構（Redis 冪等鎖、勝率反饋）八大遺漏點。
|
||
|
||
**Architecture:** `auto_repair_service.py` 呼叫 `HostRepairAgent.repair_by_uri(command)`，後者根據 URI scheme 分派至 `openclaw://`（現有 repair_lock 機制）、`ansible://`（SSH → .188 執行 ansible-playbook）、`ssh://`（直接命令，強制 approval）三條路徑。所有路徑共用 known_hosts 驗證、Redis 冪等鎖、PostgreSQL AuditLog、Langfuse Trace。
|
||
|
||
**Tech Stack:** Python 3.10+, asyncio, asyncpg/SQLAlchemy, Redis (aioredis via existing redis_client.py), Langfuse SDK (existing langfuse_client.py), K8s ConfigMap, SSH (OpenSSH subprocess)

## Task 2: known_hosts Secret + ConfigMap Ansible 白名單
|
||
|
||
**Files:**
|
||
- Create: `k8s/awoooi-prod/04-repair-known-hosts-template.yaml`
|
||
- Modify: `k8s/awoooi-prod/04-configmap.yaml`
|
||
- Modify: `k8s/awoooi-prod/06-deployment-api.yaml`
|
||
|
||
- [ ] **Step 1: 建立 known_hosts Secret template**
|
||
|
||
建立 `k8s/awoooi-prod/04-repair-known-hosts-template.yaml`：
|
||
|
||
```yaml
|
||
# k8s/awoooi-prod/04-repair-known-hosts-template.yaml
|
||
# known_hosts Secret Template — 不含實際主機指紋 (需手動建立)
|
||
# 2026-04-06 Claude Code: Sprint 3 Security Fix A1
|
||
#
|
||
# 建立方式:
|
||
# # 掃描目標主機指紋
|
||
# ssh-keyscan -H 192.168.0.110 > /tmp/known_hosts
|
||
# ssh-keyscan -H 192.168.0.188 >> /tmp/known_hosts
|
||
#
|
||
# kubectl create secret generic awoooi-repair-known-hosts \
|
||
# -n awoooi-prod \
|
||
# --from-file=known_hosts=/tmp/known_hosts
|
||
#
|
||
# 驗證:
|
||
# kubectl get secret awoooi-repair-known-hosts -n awoooi-prod
|
||
# → 應有 known_hosts key
|
||
#
|
||
# 安全說明:
|
||
# - known_hosts 存 K8s Secret，掛載至 /etc/repair-ssh/known_hosts
|
||
# - SSH 命令使用 -o UserKnownHostsFile=/etc/repair-ssh/known_hosts
|
||
# - 移除關閉 SSH host key 驗證的參數 (安全漏洞)
|
||
apiVersion: v1
|
||
kind: Secret
|
||
metadata:
|
||
name: awoooi-repair-known-hosts
|
||
namespace: awoooi-prod
|

annotations:
|
||
awoooi.io/secret-type: "ssh-known-hosts"
|
||

|
||
type: Opaque
|
||
# data: 不在版控中 — 使用上方 ssh-keyscan 指令建立
|
||
```
|
||
|
||
- [ ] **Step 2: 在 `04-configmap.yaml` 新增 Ansible 白名單**
|
||
|
||
在 `04-configmap.yaml` 的 `data:` 區塊末尾加入：
|
||
|
||
```yaml
|
||
# 2026-04-06 Claude Code: Sprint 3 — ansible:// 白名單 (Security Fix A2)
|
||
# 逗號分隔，只允許此清單中的 playbook 名稱執行
|
||
# 新增 playbook 時修改此值後重新 kubectl apply，無需重新部署 Pod
|
||
ANSIBLE_PLAYBOOK_WHITELIST: "restart_docker_service.yml,vacuum_postgres.yml,clear_redis_cache.yml"
|
||
# ansible:// 強制執行節點 (Security Fix C3: 單一控制節點)
|
||
ANSIBLE_CONTROL_NODE_HOST: "192.168.0.188"
|
||
ANSIBLE_CONTROL_NODE_USER: "ollama"
|
||
ANSIBLE_PLAYBOOKS_PATH: "~/openclaw-v5/ansible/playbooks"
|
||
```
|
||
|
||
- [ ] **Step 3: 在 `06-deployment-api.yaml` 加入 known_hosts Volume Mount**
|
||
|
||
找到現有的 `repair-ssh-key` volume mount 區塊（約在第 55 行），在其後加入：
|
||
|
||
```yaml
|
||
# 2026-04-06 Claude Code: Sprint 3 Security Fix A1 — known_hosts
|
||
- name: repair-known-hosts
|
||
mountPath: /etc/repair-ssh/known_hosts
|
||
subPath: known_hosts
|
||
readOnly: true
|
||
```
|
||
|
||
在 `volumes:` 區塊（約在第 102 行），在 `repair-ssh-key` volume 後加入：
|
||
|
||
```yaml
|
||
# 2026-04-06 Claude Code: Sprint 3 Security Fix A1
|
||
- name: repair-known-hosts
|
||
secret:
|
||
secretName: awoooi-repair-known-hosts
|
||
```
|
||
|
||
- [ ] **Step 4: 在 .188 上實際執行建立 Secrets**
|
||
|
||
```bash
|
||
# 在 .120 K3s 節點上執行
|
||
ssh wooo@192.168.0.120 "
|
||
ssh-keyscan -H 192.168.0.110 > /tmp/known_hosts_repair
|
||
ssh-keyscan -H 192.168.0.188 >> /tmp/known_hosts_repair
|
||
kubectl create secret generic awoooi-repair-known-hosts \
|
||
-n awoooi-prod \
|
||
--from-file=known_hosts=/tmp/known_hosts_repair \
|
||
--dry-run=client -o yaml | kubectl apply -f -
|
||
kubectl get secret awoooi-repair-known-hosts -n awoooi-prod
|
||
"
|
||
```
|
||
|
||
期望: `secret/awoooi-repair-known-hosts configured`
|
||
|
||
- [ ] **Step 5: Commit**
|
||
|
||
```bash
|
||
git add k8s/awoooi-prod/04-repair-known-hosts-template.yaml \
|
||
k8s/awoooi-prod/04-configmap.yaml \
|

## Task 4: Redis 冪等鎖（防重複執行）
|
||
|
||
**Files:**
|
||
- Modify: `apps/api/src/services/host_repair_agent.py`
|
||
- Test: `apps/api/tests/test_host_repair_agent.py`
|
||
|
||
Redis `RedisLock` class 已在 `src/core/redis_client.py:173` 實作，直接使用。
|
||
|
||
- [ ] **Step 1: 新增冪等鎖測試**
|
||
|
||
在 `tests/test_host_repair_agent.py` 加入：
|
||
|
||
```python
|
||
class TestRepairLock:
|
||
@pytest.mark.asyncio
|
||
async def test_duplicate_repair_is_blocked(self):
|
||
"""同一個 component 的修復，第二次呼叫應被 lock 阻擋"""
|
||
from src.services.host_repair_agent import HostRepairAgent
|
||
from unittest.mock import AsyncMock, patch
|
||
agent = HostRepairAgent()
|
||
|
||
call_count = 0
|
||
|
||
async def fake_execute_openclaw(layer, component):
|
||
nonlocal call_count
|
||
call_count += 1
|
||
await asyncio.sleep(0.1) # simulate work
|
||
return HostRepairResult(success=True, layer=layer, component=component, output="REPAIR_OK:test")
|
||
|
||
with patch.object(agent, "_execute_openclaw", side_effect=fake_execute_openclaw):
|
||
# 同時發出兩個相同的修復請求
|
||
results = await asyncio.gather(
|
||
agent.repair_by_uri("openclaw://docker-110/sentry"),
|
||
agent.repair_by_uri("openclaw://docker-110/sentry"),
|
||
return_exceptions=True,
|
||
)
|
||
|
||
# 其中一個應成功，另一個應被 lock 阻擋（返回 success=False + "already running"）
|
||
successes = [r for r in results if isinstance(r, HostRepairResult) and r.success]
|
||
blocked = [r for r in results if isinstance(r, HostRepairResult) and not r.success and "already running" in r.error]
|
||
assert len(successes) == 1
|
||
assert len(blocked) == 1
|
||
```
|
||
|
||
- [ ] **Step 2: 確認測試失敗**
|
||
|
||
```bash
|
||
python -m pytest apps/api/tests/test_host_repair_agent.py::TestRepairLock -v 2>&1 | tail -10
|
||
```
|
||
|
||
期望: `FAILED` — 因為目前 `repair_by_uri` 沒有 lock，兩次都會成功。
|
||
|
||
- [ ] **Step 3: 在 `repair_by_uri` 加入 Redis 冪等鎖**
|
||
|
||
在 `host_repair_agent.py` import 區加入：
|
||
|
||
```python
|
||
from src.core.redis_client import RedisLock, get_redis
|
||
```
|
||
|
||
在 `repair_by_uri` 開頭（parse_uri_command 之後、scheme 判斷之前）加入 lock：
|
||
|
||
```python
|
||
# Redis 冪等鎖：防止同一 component 同時被修復兩次
|
||
lock_key = f"repair_lock:ssh_command:{uri.scheme}:{uri.host_or_layer}:{uri.payload}"
|
||
try:
|
||
async with RedisLock(lock_key, timeout=SSH_TIMEOUT + 30):
|
||
# --- 實際執行邏輯 (移到此 block 內) ---
|
||
if uri.scheme == "openclaw":
|
||
...
|
||
```
|
||
|
||
> **注意**: 要把整個 scheme 判斷區塊都移到 `async with RedisLock` 內。只有 `parse_uri_command` 和 lock 建立在外面。
|
||
|
||
如果 RedisLock 無法取得（timeout），在 `except` 中返回：
|
||
|
||
```python
|
||
except Exception as lock_err:
|
||
if "timeout" in str(lock_err).lower() or "lock" in str(lock_err).lower():
|
||
return HostRepairResult(
|
||
success=False, layer=uri.scheme, component=uri.payload,
|
||
error=f"Repair already running for {uri.scheme}://{uri.host_or_layer}/{uri.payload}",
|
||
)
|
||
raise
|
||
```
|
||
|
||
- [ ] **Step 4: 確認測試通過**
|
||
|
||
```bash
|
||
python -m pytest apps/api/tests/test_host_repair_agent.py -v
|
||
```
|
||
|
||
期望: 全部 `PASSED`
|
||
|
||
- [ ] **Step 5: Commit**
|
||
|
||
```bash
|
||
git add apps/api/src/services/host_repair_agent.py apps/api/tests/test_host_repair_agent.py

- Modify: `apps/api/src/services/host_repair_agent.py`
|
||
- Test: `apps/api/tests/test_host_repair_agent.py`
|
||
|

AuditLog 寫入模式參考 `src/services/executor.py:830`，Langfuse 使用 `src/services/langfuse_client.py` 的 `langfuse_trace` context manager。
|
||
|
||
- [ ] **Step 1: 新增 AuditLog 寫入測試**
|
||
|
||

assert result.success is True
|

assert mock_db_add.called, "AuditLog should be written to DB"
|

audit_obj = mock_db_add.call_args[0][0]
|

assert audit_obj.operation_type == "SSH_COMMAND"
|

```
|

```
|
||
|
||
期望: `FAILED` — AuditLog 尚未實作
|
||
|
||
- [ ] **Step 3: 在 `host_repair_agent.py` 加入 DB import 和 `_write_audit_log` 方法**
|
||
|
||
加入 import：
|
||
|
||
```python
|
||
from src.db.base import get_db_context
|
||
from src.db.models import AuditLog
|

```

期望: `FAILED` — `_execute_step` 目前用舊的 `layer/component` 格式
|
||
|
||
- [ ] **Step 3: 修改 `auto_repair_service.py:500-513` 改用 `repair_by_uri`**
|
||
|
||
將現有的 SSH_COMMAND 區塊（第 500-513 行）整體替換為：
|
||
|
||
```python
|
||
# 2026-04-06 Claude Code: Sprint 3 — repair_by_uri (URI scheme 路由)
|
||
if step.action_type == ActionType.SSH_COMMAND:
|
||
from src.services.host_repair_agent import HostRepairAgent
|
||
agent = HostRepairAgent()
|
||
approved = not getattr(step, "requires_approval", False)
|
||
result = await agent.repair_by_uri(step.command, approved=approved)
|
||
if result.success:
|
||
# 勝率反饋: 寫回 Playbook success_count
|
||
if hasattr(self, "_playbook_service") and self._playbook_service:
|
||
playbook_id = getattr(incident, "_matched_playbook_id", None)
|
||
if playbook_id:
|
||
await self._playbook_service.record_execution(playbook_id, success=True)
|
||
return f"SUCCESS: {result.output}"
|
||
else:
|
||
if hasattr(self, "_playbook_service") and self._playbook_service:
|
||
playbook_id = getattr(incident, "_matched_playbook_id", None)
|
||
if playbook_id:
|
||
await self._playbook_service.record_execution(playbook_id, success=False)
|
||
return f"FAILED: {result.error}"
|
||
```
|
||
|
||
- [ ] **Step 4: 確認所有 auto_repair 測試通過**
|
||
|
||
```bash
|
||
python -m pytest apps/api/tests/test_auto_repair_service.py -v
|
||
```
|
||
|
||
期望: 全部 `PASSED`（包含原有測試）
|
||
|
||
- [ ] **Step 5: 跑完整測試套件確認沒有退化**
|
||
|
||
```bash
|
||
python -m pytest apps/api/tests/ -v --ignore=apps/api/tests/e2e_network_test.py 2>&1 | tail -20
|
||
```
|
||
|
||
期望: 全部 `PASSED`，zero failures
|
||
|
||
- [ ] **Step 6: Commit**
|
||
|
||
```bash
|
||
git add apps/api/src/services/auto_repair_service.py apps/api/tests/test_auto_repair_service.py
|
||
git commit -m "feat(api): auto_repair_service 整合 repair_by_uri + 勝率反饋 (Sprint 3 T6)"
|
||
```

## Task 7: Ansible Playbook 建立 + E2E 驗證
|
||
|
||
**Files:**
|
||
- Create: `openclaw-v5/ansible/playbooks/restart_docker_service.yml` (on .188)
|
||
- Create: `openclaw-v5/ansible/playbooks/vacuum_postgres.yml` (on .188)
|
||
|
||
這個 task 在 .188 主機上執行，不在本地 repo。
|
||
|
||
- [ ] **Step 1: 在 .188 建立 `restart_docker_service.yml`**
|
||
|
||
```bash
|
||
ssh ollama@192.168.0.188 "cat > ~/openclaw-v5/ansible/playbooks/restart_docker_service.yml << 'EOF'
|
||
---
|
||
# restart_docker_service.yml
|
||
# 重啟指定 Docker 容器 (docker compose up -d)
|
||
# 使用方式: ansible-playbook restart_docker_service.yml -e \"service_name=sentry\"
|
||
# 2026-04-06 Claude Code: Sprint 3 Ansible Seed Playbook
|
||
- name: Restart Docker Service
|
||
hosts: all
|

|
||
compose_dir: \"/opt/{{ service_name }}\"
|
||
tasks:

|
||
stat:
|
||
path: \"{{ compose_dir }}/docker-compose.yml\"
|
||
register: compose_file
|
||
failed_when: not compose_file.stat.exists
|
||
|
||
- name: Restart service via docker compose
|
||
shell: cd {{ compose_dir }} && docker compose up -d
|
||
register: result
|
||
|
||
- name: Print result
|
||
debug:
|
||
msg: \"REPAIR_OK:{{ service_name }} restarted. {{ result.stdout }}\"
|
||
EOF
|
||
echo 'Created restart_docker_service.yml'"
|
||
```
|
||
|
||
- [ ] **Step 2: 在 .188 建立 `vacuum_postgres.yml`**
|
||
|
||
```bash
|
||
ssh ollama@192.168.0.188 "cat > ~/openclaw-v5/ansible/playbooks/vacuum_postgres.yml << 'EOF'
|
||

|
||
# vacuum_postgres.yml
|
||
# 清理 PostgreSQL 磁碟空間 (VACUUM FULL ANALYZE)
|
||
# 2026-04-06 Claude Code: Sprint 3 Ansible Seed Playbook
|
||
- name: Vacuum PostgreSQL
|
||
hosts: db
|
||
gather_facts: false
|
||
tasks:
|
||
- name: Run VACUUM FULL ANALYZE
|
||
become: true
|
||
become_user: postgres
|
||
shell: psql -c \"VACUUM FULL ANALYZE;\"
|
||
register: vacuum_result
|
||
|
||
- name: Check disk usage after vacuum
|
||
shell: df -h /var/lib/postgresql/
|
||
register: disk_result
|
||
|
||
- name: Print result
|
||
debug:
|
||
msg: \"REPAIR_OK:vacuum_postgres completed. {{ vacuum_result.stdout }}. Disk: {{ disk_result.stdout }}\"
|
||
EOF
|
||
echo 'Created vacuum_postgres.yml'"
|
||
```
|
||
|
||
- [ ] **Step 3: E2E 測試 — 從 K3s Pod 發出 openclaw:// 修復**
|
||
|
||
```bash
|
||
# 找到 awoooi-api pod
|
||
ssh wooo@192.168.0.120 "kubectl get pods -n awoooi-prod | grep awoooi-api"
|
||
|
||
# 模擬呼叫 auto-repair evaluate，確認 SSH_COMMAND playbook 能被匹配
|
||
ssh wooo@192.168.0.120 "curl -s http://192.168.0.125:32334/api/v1/playbooks/ | \
|
||
python3 -c \"import json,sys; pbs=json.load(sys.stdin)['items']; \
|
||
[print(p['playbook']['name'], p['playbook']['status']) for p in pbs if 'ssh_command' in str(p)]\""
|
||
```
|
||
|
||
- [ ] **Step 4: Push 到 Gitea 觸發 CD**
|
||
|
||
```bash
|
||
git push gitea main
|
||
```
|
||
|
||
等待 CD pipeline 成功（約 8 分鐘），確認新版本 Pod 啟動。
|
||
|
||
- [ ] **Step 5: 確認 Pod 有新版本**
|
||
|
||
```bash
|
||
ssh wooo@192.168.0.120 "kubectl get pods -n awoooi-prod -l app=awoooi-api -o jsonpath='{.items[0].metadata.name}' | xargs -I{} kubectl exec {} -n awoooi-prod -- python3 -c \"from src.services.host_repair_agent import parse_uri_command; r=parse_uri_command('openclaw://docker-110/sentry'); print('OK:', r.scheme)\""
|
||
```
|
||
|
||
期望: `OK: openclaw`

## Self-Review 檢查
|
||
|
||
**Spec coverage:**
|
||
- ✅ A1: known_hosts — Task 2 + Task 3 Step 5
|
||
- ✅ A2: ConfigMap 白名單 — Task 2 + Task 3 `validate_ansible_playbook`
|
||
- ✅ A3: Shell Injection — Task 1 `validate_shell_safety` + Task 3 `ssh://` 路徑
|
||
- ✅ B1: AuditLog PostgreSQL — Task 5
|
||
- ✅ B2: Langfuse Trace — Task 5
|
||
- ✅ C1: Redis 冪等鎖 — Task 4
|
||
- ✅ C2: 勝率反饋 — Task 6 `record_execution`
|
||
- ✅ C3: .188 執行節點 — Task 3 `_execute_ansible` (ANSIBLE_CONTROL_HOST 強制 .188)
|
||
|
||
**Placeholder scan:** 無 TBD / TODO。所有程式碼都是完整實作。
|
||
|
||
**Type consistency:** `HostRepairResult` dataclass 在 Task 1 定義（已存在），所有後續 task 返回同一型別。`repair_by_uri(command: str, approved: bool = False) -> HostRepairResult` 在 Task 3 定義，Task 4/5/6 都正確使用此簽名。
