1. Docker Stack 核心概念

1.1 Stack vs Compose

1.1.1 核心差异对比

特性	Docker Compose	Docker Stack	适用场景
运行环境	单机 Docker	Swarm 集群	Stack 用于集群 ✅
服务发现	Docker Network	内置 DNS	Stack 更强大
负载均衡	无	内置 LB	Stack 原生支持 ✅
滚动更新	手动	自动	Stack 自动化 ✅
副本管理	手动 scale	声明式	Stack 更优雅
配置管理	环境变量	Configs/Secrets	Stack 更安全 ✅
部署命令	`docker compose up`	`docker stack deploy`	-

1.1.2 语法差异

# docker-compose.yml (Compose 语法)
version: '3.8'

services:
  web:
    image: nginx:alpine
    deploy:
      replicas: 3
      resources:
        limits:
          cpus: '0.5'
          memory: 256M
    ports:
      - "80:80"

# docker-compose.yml (Stack 语法 - 基本相同)
# 区别：Stack 支持 configs/secrets，支持更多 deploy 选项
version: '3.8'

services:
  web:
    image: nginx:alpine
    deploy:
      replicas: 3
      resources:
        limits:
          cpus: '0.5'
          memory: 256M
      update_config:
        parallelism: 1
        delay: 10s
        failure_action: rollback
    ports:
      - "80:80"
    configs:
      - nginx-config
    secrets:
      - db-password

configs:
  nginx-config:
    file: ./nginx.conf

secrets:
  db-password:
    external: true

1.2 Stack 架构设计

1.2.1 完整部署架构

1.3 部署流程解析

1.3.1 部署源码解析

// Docker Stack 部署源码
// 位置：github.com/docker/cli/cli/command/stack/deploy.go

func runDeploy(dockerCli *cli.DockerCli, opts deployOptions) error {
    // 1. 解析 Compose 文件
    composeFile, err := loader.Load(opts.composefile)
    if err != nil {
        return err
    }
    
    // 2. 转换为 Swarm 服务规格
    services := convertServices(composeFile.Services)
    configs := convertConfigs(composeFile.Configs)
    secrets := convertSecrets(composeFile.Secrets)
    networks := convertNetworks(composeFile.Networks)
    
    // 3. 创建或更新网络
    for _, network := range networks {
        if err := createOrUpdateNetwork(network); err != nil {
            return err
        }
    }
    
    // 4. 创建或更新配置/密钥
    for _, config := range configs {
        if err := createConfig(config); err != nil {
            return err
        }
    }
    
    for _, secret := range secrets {
        if err := createSecret(secret); err != nil {
            return err
        }
    }
    
    // 5. 创建或更新服务
    for _, service := range services {
        if err := createOrUpdateService(service); err != nil {
            return err
        }
    }
    
    // 6. 显示部署状态
    return displayStatus(dockerCli, opts.namespace)
}

// 服务创建/更新逻辑
func createOrUpdateService(service swarm.ServiceSpec) error {
    client := dockerCli.Client()
    ctx := context.Background()
    
    // 检查服务是否存在
    existingService, _, err := client.ServiceInspectWithRaw(ctx, service.Name, types.ServiceInspectOptions{})
    
    if err != nil {
        // 服务不存在，创建新服务
        _, err := client.ServiceCreate(ctx, service, types.ServiceCreateOptions{})
        return err
    } else {
        // 服务已存在，更新服务
        err := client.ServiceUpdate(ctx, existingService.ID, existingService.Version, service, types.ServiceUpdateOptions{})
        return err
    }
}

2. Stack 部署完全指南

2.1 docker stack deploy 详解

2.1.1 完整命令语法

# 基本语法
docker stack deploy [OPTIONS] STACK

# 常用参数
-c, --compose-file stringArray    # Compose 文件（可多个）
--prune                           # 清理未使用的服务
--resolve-image string            # 镜像解析策略 (always|changed|never)
--with-registry-auth              # 发送仓库认证信息

2.1.2 部署示例

# 1. 基础部署
docker stack deploy -c docker-compose.yml myapp

# 2. 多文件部署（覆盖配置）
docker stack deploy \
  -c docker-compose.yml \
  -c docker-compose.prod.yml \
  myapp

# 3. 带仓库认证部署
docker stack deploy \
  -c docker-compose.yml \
  --with-registry-auth \
  myapp

# 4. 清理未使用服务
docker stack deploy \
  -c docker-compose.yml \
  --prune \
  myapp

# 5. 指定镜像解析策略
docker stack deploy \
  -c docker-compose.yml \
  --resolve-image always \
  myapp

2.2 常用命令参考

2.2.1 Stack 管理命令

# 查看 Stack 列表
docker stack ls

# 查看 Stack 服务
docker stack services myapp

# 查看 Stack 任务
docker stack ps myapp

# 查看 Stack 配置
docker stack config -c docker-compose.yml

# 移除 Stack
docker stack rm myapp

# 查看 Stack 详情
docker stack ls --format "table {{.Name}}\t{{.Services}}\t{{.Resources}}"

2.2.2 监控命令

#!/bin/bash
# monitor-stack.sh - Stack 监控脚本

set -euo pipefail

STACK_NAME="$1"

log() {
    echo "[$(date +'%H:%M:%S')] $1"
}

log "=== 监控 Stack: $STACK_NAME ==="

# 1. 显示服务状态
log "[服务状态]"
docker stack services $STACK_NAME

# 2. 显示任务分布
log ""
log "[任务分布]"
docker stack ps $STACK_NAME --format "table {{.Name}}\t{{.Node}}\t{{.CurrentState}}\t{{.DesiredState}}"

# 3. 显示资源使用
log ""
log "[资源使用]"
docker service ls --format "{{.Name}}" | grep "^${STACK_NAME}_" | while read service; do
    log "$service:"
    docker stats --no-stream $service --format "table {{.Container}}\t{{.CPUPerc}}\t{{.MemUsage}}"
done

# 4. 实时监控
log ""
log "[实时监控] (Ctrl+C 停止)"
watch -n 2 "docker stack services $STACK_NAME"

2.3 部署策略优化

2.3.1 滚动更新优化

# docker-compose.yml - 优化滚动更新
version: '3.8'

services:
  web:
    image: myapp:latest
    deploy:
      replicas: 6
      update_config:
        parallelism: 2         # 每次更新 2 个副本
        delay: 10s             # 每个批次间隔 10 秒
        failure_action: rollback  # 失败回滚
        monitor: 30s           # 监控健康状态 30 秒
        max_failure_ratio: 0.1  # 允许 10% 失败率
        order: start-first     # 先启动新的，再停止旧的
      
      rollback_config:
        parallelism: 2
        delay: 10s
        monitor: 30s
        failure_action: pause

5.3 SSL 终止

5.3.1 SSL 证书配置

#!/bin/bash
# ssl-certificate-setup.sh - SSL 证书配置

set -euo pipefail

# 1. 生成自签名证书（测试用）
openssl req -x509 -nodes -days 365 -newkey rsa:2048 \
    -keyout server.key \
    -out server.crt \
    -subj "/C=CN/ST=Beijing/L=Beijing/O=Example/CN=example.com"

# 2. 合并证书
cat server.crt server.key > server.pem

# 3. 设置权限
chmod 600 server.pem
chmod 600 server.key

# 4. 创建 Secret
docker secret create haproxy-ssl server.pem

echo "✓ SSL 证书配置完成"

初识智能体

在过去两年中，几乎所有人都体验过大语言模型（如 ChatGPT、Claude、DeepSeek）的强大能力：写周报、润色邮件、解答编程疑难。被动响应：你问一句，它答一句。如果你的 Prompt 没有写清楚约束条件，它无法主动追问或修正目标。知行脱节：大模型能用流畅的文字告诉你“如何部署一个高可用 K8s 集群”，但它无法替你登录服务器敲下命令、查看报错日志并自动回滚。信息孤岛：大模型的知识止步于预
