# Agent 安裝 Runbook：agent-secret-vault
|
||
|
||
這份文件給 AI agent / cron worker / automation 使用。目標：把 `agent-secret-vault` 安裝好、缺檔時建立 placeholder、並能安全讀取 secrets。
|
||
|
||
## 安全規則
|
||
|
||
- 不要把 secret value、vault password、token、private key 印到 chat / log / 工單 comment。
|
||
- 不要 dump 整份解密後的 `secrets/vault.yml`。
|
||
- 只讀取任務所需的單一欄位。
|
||
- 所有暫存解密檔用完立即刪除。
|
||
|
||
## 目標路徑
|
||
|
||
- Repo：`~/projects/agent-secret-vault`
|
||
- Vault 檔：`~/projects/agent-secret-vault/secrets/vault.yml`
|
||
- Vault password file：`~/.config/vault-pass.txt`
|
||
- 可覆寫環境變數：`VAULT_PASS_FILE=/custom/path`
|
||
|
||
## 1. 安裝系統依賴
|
||
|
||
```bash
|
||
sudo apt update
|
||
sudo apt install -y git ansible unzip
|
||
```
|
||
|
||
驗證：
|
||
|
||
```bash
|
||
command -v git
|
||
command -v ansible-vault
|
||
command -v unzip
|
||
```
|
||
|
||
## 2. Clone repo
|
||
|
||
```bash
|
||
mkdir -p ~/projects
|
||
cd ~/projects
|
||
if [ ! -d agent-secret-vault/.git ]; then
|
||
git clone ssh://git@gitea.cowbay.org:2203/hermes/agent-secret-vault.git
|
||
fi
|
||
cd agent-secret-vault
|
||
```
|
||
|
||
若 clone 失敗，建立 placeholder 讓後續步驟可明確回報缺什麼：
|
||
|
||
```bash
|
||
mkdir -p ~/projects/agent-secret-vault/{scripts,secrets,docs}
|
||
cat > ~/projects/agent-secret-vault/README.PLACEHOLDER.md <<'PLACEHOLDER'
|
||
# Placeholder
|
||
|
||
agent-secret-vault repo 尚未成功 clone。
|
||
需要 Gitea SSH 權限：ssh://git@gitea.cowbay.org:2203/hermes/agent-secret-vault.git
|
||
PLACEHOLDER
|
||
```
|
||
|
||
然後回報人類：需要把此 agent / 機器的 SSH public key 加到 Gitea 或 deploy key。
|
||
|
||
## 3. 安裝 vault password file
|
||
|
||
標準位置：
|
||
|
||
```text
|
||
~/.config/vault-pass.txt
|
||
```
|
||
|
||
安裝來源是 repo 內的密碼保護壓縮檔：
|
||
|
||
```text
|
||
secrets/vault-pass.txt.zip
|
||
```
|
||
|
||
執行：
|
||
|
||
```bash
|
||
cd ~/projects/agent-secret-vault
|
||
./scripts/install-vault-pass.sh
|
||
```
|
||
|
||
安裝過程會要求使用者手動輸入壓縮檔密碼；解壓成功後會寫入：
|
||
|
||
```text
|
||
~/.config/vault-pass.txt
|
||
```
|
||
|
||
權限應為 `600`。
|
||
|
||
### 若壓縮檔不存在
|
||
|
||
建立 placeholder，不要自行編造密碼：
|
||
|
||
```bash
|
||
mkdir -p ~/projects/agent-secret-vault/secrets
|
||
cat > ~/projects/agent-secret-vault/secrets/vault-pass.txt.zip.PLACEHOLDER <<'PLACEHOLDER'
|
||
Missing file: secrets/vault-pass.txt.zip
|
||
Purpose: password-protected archive containing vault-pass.txt
|
||
Action: ask human maintainer to provide this archive or commit it to the private repo.
|
||
PLACEHOLDER
|
||
```
|
||
|
||
然後回報人類：缺 `secrets/vault-pass.txt.zip`，需要提供。
|
||
|
||
### 若要用非預設路徑
|
||
|
||
```bash
|
||
export VAULT_PASS_FILE=/path/to/vault-pass.txt
|
||
./scripts/install-vault-pass.sh /path/to/vault-pass.txt.zip
|
||
```
|
||
|
||
## 4. 驗證安裝
|
||
|
||
```bash
|
||
cd ~/projects/agent-secret-vault
|
||
ansible-vault view secrets/vault.yml --vault-password-file ~/.config/vault-pass.txt >/dev/null
|
||
```
|
||
|
||
成功：exit code 0。失敗時只回報錯誤摘要，不要輸出密碼或 vault 內容。
|
||
|
||
## 5. 讀取單一 secret
|
||
|
||
```bash
|
||
cd ~/projects/agent-secret-vault
|
||
./scripts/get-secret.sh <dot.path>
|
||
```
|
||
|
||
範例：
|
||
|
||
```bash
|
||
./scripts/get-secret.sh gitea.api_token
|
||
./scripts/get-secret.sh openclaw_alice.http_nodes.gitea.password
|
||
```
|
||
|
||
把輸出直接交給需要 secret 的動作使用；不要貼到 chat / log。
|
||
|
||
## 6. Worker 需要 env 時
|
||
|
||
```bash
|
||
cd ~/projects/agent-secret-vault
|
||
umask 077
|
||
./scripts/render-env.sh gitea > /tmp/gitea.env
|
||
set -a
|
||
. /tmp/gitea.env
|
||
set +a
|
||
rm -f /tmp/gitea.env
|
||
```
|
||
|
||
使用完如果擔心環境被 dump，執行 `unset` 清掉相關變數。
|
||
|
||
## 7. 更新 secret 的 agent 流程
|
||
|
||
只有在人類明確要求更新 secrets 時才做：
|
||
|
||
```bash
|
||
cd ~/projects/agent-secret-vault
|
||
git pull --ff-only
|
||
./scripts/vault.sh edit
|
||
ansible-vault view secrets/vault.yml --vault-password-file ~/.config/vault-pass.txt >/dev/null
|
||
git add secrets/vault.yml
|
||
git commit -m "Update secret <key-name>"
|
||
git push
|
||
```
|
||
|
||
回報只包含 key 名稱、commit hash、驗證方式；不要包含 secret value。
