Process Compose调度编排工具

Process Compose 是一个调度编排工具，不过不是用来调度容器的，而是用来调度非容器化的应用，可以定义进程的依赖性和启动顺序，也可以定义重启策略。它的编排文件内容格式和 Docker Compose 比较类似，例如：

version: "0.5"

environment:
  - "GLOBAL_ENV_VAR=1"
log_location: /path/to/combined/output/logfile.log
log_level: debug

processes:
  Manager:
    command: "/path/to/manager"
    availability:
      restart: "always"
    depends_on:
      ClientA:
        condition: process_started
      ClientB:
        condition: process_started

  ClientA:
    command: "/path/to/ClientA"
    availability:
      restart: "always"
    depends_on:
      Server_1A:
        condition: process_started
      Server_2A:
        condition: process_started
    environment:
      - "LOCAL_ENV_VAR=1"

  ClientB:
    command: "/path/to/ClientB -some -arg"
    availability:
      restart: "always"
    depends_on:
      Server_1B:
        condition: process_started
      Server_2B:
        condition: process_started
    environment:
      - "LOCAL_ENV_VAR=2"

  Server_1A:
    command: "/path/to/Server_1A"
    availability:
      restart: "always"

  Server_2A:
    command: "/path/to/Server_2A"
    availability:
      restart: "always"

  Server_1B:
    command: "/path/to/Server_1B"
    availability:
      restart: "always"

  Server_2B:
    command: "/path/to/Server_2B"
    availability:
      restart: "always"
