简介
微服务架构前期 ,服务高可用解决方案。
- 服务名称：
配置
config.yaml
位置： /conf/config.yaml
- SERVER 服务名称
- PUBLIC_CONF 公共配置文件地址
- SERVER_PORT 服务端口
services.json
位置： /conf/services.json
- name 服务名称
- priority 优先级
- isInit 是否属于初始化服务 （如果为true 优先级高于所有 为false的服务）
- isDaemon 是否守护进程（如果 false 仅godaemon 服务启动时拉起一次）
- script 脚本
- execPath 脚本执行路径
- programFilePath 执行程序路径 程序自动拼接 公共工作路径（公共配置中的rootpath）
- startCommand 启动指令
- stopCommand 停止指令
- healthCheck 保活验证
- isHealthCheck 是否启用此验证
- interval 运行状况检查将在容器启动后首先运行interval秒，然后在每次之前的检查完成后再次运行interval秒
- start_period 为需要时间引导的容器提供初始化时间。在此期间的探测失败将不计入最大重试次数。但是，如果在启动期间健康检查成功，则认为容器已启动，所有连续失败都将计入最大重试次数。
- retries 重试次数
