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
},
"2": {
"host": "app2",
"quorumPort": 36463,
"electionPort": 36464,
"groupId": null,
"weight": null
},
"3": {
"host": "app2",
"quorumPort": 36463,
"electionPort": 36464,
"groupId": null,
"weight": null
}
},
"secret": "JqJAkZ!oZ6MNx4rBpIH8M*yuVWXDULgR",
"additionalProperties": {},
"timeoutMillis": null,
"numWorkers": null,
"maxLogCount": null,
"minLogAgeMillis": null
},
运行效果

说明
centraldogma 的ha 使用了内嵌模式的zk，或者部署起来还是比较方便的（但是注意如果使用了容器数据持久化必须做）,以下是参考的数据格式
（容器内部存储，内嵌zk的数据目录）
