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"
