centraldogma ha 配置

centraldogma 支持ha模式的运行（依赖zk），以下是参考配置

环境准备

docker-compose

version: "3"

services: 

    app:

        image: line/centraldogma

        volumes: 

        - "./shiro.ini:/opt/centraldogma/conf/shiro.ini"

        - "./dogma.json:/opt/centraldogma/conf/dogma.json"

        ports: 

        - "36462:36462"

    app2:

        image: line/centraldogma

        volumes: 

        - "./shiro.ini:/opt/centraldogma/conf/shiro.ini"

        - "./dogma2.json:/opt/centraldogma/conf/dogma.json"

        ports: 

        - "36463:36462"

    app3:

        image: line/centraldogma

        volumes: 

        - "./shiro.ini:/opt/centraldogma/conf/shiro.ini"

        - "./dogma3.json:/opt/centraldogma/conf/dogma.json"

        ports: 

        - "36464:36462"

配置
主要是关于dogma的,核心如下，具体参考github

 
"replication" : {

        "method": "ZOOKEEPER",

        "serverId": 1, // id 需要不同，因为使用了嵌入的zk，实际上就是myid，需要不同，而且需要奇数节点

        "servers": {

          "1": {

            "host": "app",

            "quorumPort": 36463,

            "electionPort": 36464,

            "groupId": null,

            "weight": null

          },

            "groupId": null,

            "weight": null

          }

        },

        "secret": "JqJAkZ!oZ6MNx4rBpIH8M*yuVWXDULgR",
