No-CI/CD Deploy Assistant | 無 CI/CD 部署助手

Language: English | 繁體中文

Guide reliable deployments in environments without GitHub Actions or GitLab CI, using a three-layer architecture: prevent errors, verify correctness, recover fast.

引導無 CI/CD 平台環境下的可靠部署，採用三層架構：防錯、驗證、快速回復。

Three-Layer Architecture | 三層部署架構

Layer 1: Prevent Wrong Deployments   Layer 2: Verify Correctness   Layer 3: Fast Recovery
  set -euo pipefail                    Smoke Test + /health           Blue-Green switching
  Version tag enforcement              Version number comparison      rollback.sh < 30s
  deploy.lock concurrency guard        Auto-rollback on failure

Interactive Questionnaire | 引導式問答

Question	Options	Impact
Project type	node / python / go / docker	Build command
Deploy target	SSH+rsync / Docker Compose	Transfer method
Blue-Green support	yes / no	rollback.sh generation
Health check URL	URL input	verify.sh target
Version source	VERSION file / package.json / git tag	Version comparison logic

Generated Script Set | 生成的腳本組

deploy.sh — Main Deploy Script

#!/usr/bin/env bash
set -euo pipefail

LOCK_FILE="/tmp/deploy.lock"
trap "rm -f $LOCK_FILE" EXIT

# Concurrency guard | 防並發
if [ -f "$LOCK_FILE" ]; then
  echo "❌ Deploy in progress (PID: $(cat $LOCK_FILE))"
  exit 1
fi
echo $$ > "$LOCK_FILE"

# Version tag enforcement | 版本 tag 強制
CURRENT_TAG=$(git describe --exact-match --tags HEAD 2>/dev/null || echo "")
if [ -z "$CURRENT_TAG" ]; then
  echo "❌ No version tag on HEAD. Run: git tag vX.Y.Z && git push --tags"
  exit 1
fi

echo "[1/4] Running tests..."
# {TEST_COMMAND}

echo "[2/4] Building artifact..."
# {BUILD_COMMAND}

echo "[3/4] Syncing to server..."
rsync -avz --delete ./dist/ {USER}@{SERVER}:/app/

echo "[4/4] Verifying deployment..."
./verify.sh || { echo "Verification failed, rolling back..."; ./rollback.sh; exit 1; }

echo "{\"timestamp\":\"$(date -u +%Y-%m-%dT%H:%M:%SZ)\",\"version\":\"$CURRENT_TAG\",\"operator\":\"$(whoami)\",\"result\":\"success\"}" >> /var/log/deployments.jsonl
echo "✅ Deploy successful: $CURRENT_TAG"

verify.sh — Smoke Test

#!/usr/bin/env bash
set -euo pipefail

HEALTH_URL="${HEALTH_URL:-{HEALTH_URL}}"
EXPECTED_VERSION=$(cat VERSION)

for i in $(seq 1 3); do
  RESPONSE=$(curl -sf --max-time 10 "$HEALTH_URL" 2>/dev/null) && break
  echo "Health check attempt $i/3 failed, retrying in 5s..."
  sleep 5
done

ACTUAL_VERSION=$(echo "$RESPONSE" | python3 -c "import json,sys; print(json.load(sys.stdin)['version'])")

if [ "$ACTUAL_VERSION" != "$EXPECTED_VERSION" ]; then
  echo "❌ Version mismatch! Expected $EXPECTED_VERSION, got $ACTUAL_VERSION"
  exit 1
fi

echo "✅ Version verified: $ACTUAL_VERSION"

rollback.sh — Blue-Green Rollback

#!/usr/bin/env bash
set -euo pipefail

CURRENT=$(readlink /app/current 2>/dev/null || echo "/app/blue")
TARGET=$([[ "$CURRENT" == *"green"* ]] && echo "/app/blue" || echo "/app/green")

ln -sfn "$TARGET" /app/current
nginx -s reload

echo "✅ Rolled back to $TARGET ($(date -u +%Y-%m-%dT%H:%M:%SZ))"
echo "{\"timestamp\":\"$(date -u +%Y-%m-%dT%H:%M:%SZ)\",\"event\":\"rollback\",\"from\":\"$CURRENT\",\"to\":\"$TARGET\",\"operator\":\"$(whoami)\"}" >> /var/log/deployments.jsonl

Makefile

.PHONY: deploy rollback verify status

deploy:
	@./deploy.sh

rollback:
	@./rollback.sh

verify:
	@./verify.sh

status:
	@echo "Current slot: $$(readlink /app/current 2>/dev/null || echo 'N/A')"
	@curl -s $${HEALTH_URL:-http://localhost/health} | python3 -m json.tool 2>/dev/null || echo "Health check failed"

Output Checklist | 輸出確認清單

After generation, AI assistant must confirm:

• deploy.sh includes set -euo pipefail
• deploy.sh includes deploy.lock concurrency guard
• verify.sh compares version number (not just HTTP 200)
• rollback.sh triggers automatically on verify failure
• Makefile provides make deploy / make rollback / make status

Usage | 使用方式

/deploy              # Interactive mode — auto-detect project type
/deploy node         # Node.js project, generate directly
/deploy docker       # Docker Compose deploy mode
/deploy --verify-only  # Generate verify.sh only

Next Steps Guidance | 下一步引導

After /deploy completes, the AI assistant should suggest:

Deploy scripts generated. Suggested next steps / 部署腳本已生成，建議下一步：

• chmod +x deploy.sh verify.sh rollback.sh — Set executable permissions | 設定執行權限
• make verify — Test health check configuration | 測試健康檢查設定
• git tag v1.0.0 && git push --tags — Create version tag | 建立版本 tag
• make deploy — First deployment | 執行第一次部署
