| Information | Purpose |
|---|---|
| Service names | Track which containers to monitor |
| Exposed ports | Know which ports to check |
| Health check definitions | Use native health checks if defined |
| Dependencies (depends_on) | Understand startup order |
| Volume mounts | Verify paths exist |
| 信息内容 | 用途 |
|---|---|
| 服务名称 | 跟踪需要监控的容器 |
| 暴露端口 | 明确需要检查的端口 |
| 健康检查定义 | 若已定义则使用原生健康检查 |
| 依赖关系（depends_on） | 明确启动顺序 |
| 卷挂载 | 验证挂载路径是否存在 |
| Aspect | Strategy |
|---|---|
| Build context | Use paths from compose file |
| Build args | Pass through from compose configuration |
| Cache | Use Docker layer cache for speed |
| Failure | Report build errors with full log |
| 方面 | 策略 |
|---|---|
| 构建上下文 | 使用Compose文件中指定的路径 |
| 构建参数 | 直接传递Compose配置中的参数 |
| 缓存 | 利用Docker层缓存提升速度 |
| 失败处理 | 报错并提供完整构建日志 |
| Aspect | Strategy |
|---|---|
| Startup order | Respect depends_on and healthcheck conditions |
| Detached mode | Run in background |
| Network | Use compose-defined networks |
| Volumes | Mount all defined volumes |
| 方面 | 策略 |
|---|---|
| 启动顺序 | 遵循depends_on和健康检查条件 |
| 后台模式 | 在后台运行容器 |
| 网络 | 使用Compose定义的网络 |
| 卷 | 挂载所有已定义的卷 |
| Condition | Strategy |
|---|---|
Service has | Use native Docker health status |
Service has | Wait for Docker health status |
| No healthcheck defined | Use external HTTP probe with retry |
| Parameter | Value | Rationale |
|---|---|---|
| Max attempts | 10 | Allow slow-starting services |
| Initial delay | 5s | Give containers time to start |
| Backoff | Exponential (5, 10, 20, 40s) | Avoid overwhelming services |
| Max total wait | 120s | Reasonable upper limit |
| Method | When to Use |
|---|---|
| Docker health status | When container has healthcheck defined |
| HTTP GET to exposed port | For web services without healthcheck |
| Container exec | For services without exposed ports |
| TCP port check | For databases and message queues |
| 条件 | 策略 |
|---|---|
服务在Compose中定义了 | 使用Docker原生健康状态 |
服务定义了 | 等待Docker健康状态 |
| 未定义健康检查 | 使用外部HTTP探测并重试 |
| 参数 | 取值 | 理由 |
|---|---|---|
| 最大尝试次数 | 10 | 为启动较慢的服务预留时间 |
| 初始延迟 | 5秒 | 给容器启动预留时间 |
| 退避策略 | 指数退避（5、10、20、40秒） | 避免压垮服务 |
| 最长总等待时间 | 120秒 | 合理的上限值 |
| 方法 | 使用场景 |
|---|---|
| Docker健康状态 | 容器已定义健康检查时 |
| 向暴露端口发送HTTP GET请求 | 无健康检查的Web服务 |
| 容器内执行命令 | 无暴露端口的服务 |
| TCP端口检查 | 数据库和消息队列服务 |
