zeebe 目前还在一直的开发中，同时一些变动还是挺大的，比如simple monitor 的以前是不需要配置HazelcastExporter的
估计是为了进行集群功能处理，新添加的，以前写的配置基本都没法使用了，所以写了一个新的运行配置
说明运行的时候注意版本，我测试的是Zeebe 0.17.0，可能其他版本有变动
环境准备
- docker-compose 文件
es 使用aws 开源的，同时禁用了ssl，使用http 请求

- 几个exporter 下载
写好了一个简单的shell，执行就可以了，或者clone github 代码 camunda-zeebe-es-exporter-demo
#!/bin/bash
wget https://github.com/zeebe-io/zeebe-simple-monitor/releases/download/0.13.0/zeebe-simple-monitor-exporter-0.13.0.jar
wget https://github.com/zeebe-io/zeebe-hazelcast-exporter/releases/download/0.2.0/zeebe-hazelcast-exporter-0.2.0.jar- zeebe 配置
主要是几个exporter 的配置,es 以及simple monitor 的,配置有点多，只写添加的，完整参考githubcamunda-zeebe-es-exporter-demo
[[exporters]]
id = "simple-monitor"
className = "io.zeebe.monitor.SimpleMonitorExporter"
[exporters.args]
jdbcUrl = "jdbc:h2:tcp://db:1521/zeebe-monitor"
driverName = "org.h2.Driver"
userName = "sa"
password = ""
[[exporters]]
id = "hazelcast"
className = "io.zeebe.hazelcast.exporter.HazelcastExporter"
[[exporters]]
id = "elasticsearch"
className = "io.zeebe.exporter.ElasticsearchExporter"
[exporters.args]
url = "http://odfe-node1:9200"
[exporters.args.bulk]
delay = 5
size = 1_000
[exporters.args.authentication]
username = "admin"
password = "admin"
[exporters.args.index]
prefix = "zeebe-record"
## 这个参数挺重要，设置为true，有异常，false 是可以的，应该和es版本有关系
createTemplate = false
command = false
event = true
rejection = false
deployment = true
incident = true
job = true
message = false
messageSubscription = false
raft = false
workflowInstance = true
workflowInstanceSubscription = false启动&&测试
- 启动
docker-compose up -d- 几个问题
我们需要配置宿主机几个参数
vm.max_map_count：
/etc/sysctl.conf 添加
vm.max_map_count=262144 生效 sysctl -p
容器启动失败，可能需要设置挂载目录权限，简单的方法是 chmod 777 odfe-data1 odfe-data2 - 效果
es 集群
monitor 
- 创建一个部署
github 代码中包含一个简单的bpmn 的文件，是一个简单的流程
运行实例效果 
es 集群数据，deploy 
es 集群数据，job
说明
这个只是简单的测试，zeebe 的设计还是很灵活的，团队的规划是q2 可以产品可用，还是很期待的，实际上使用zeebe 做为我们微服务中的一个
编排工具，还是很强大的，而且集成opendistro for es 强大的功能，我们可以完成好多方便的应用开发
