zeebe 0.20.0 是生产可用的第一个版本，同时也有好多变动，以下是一个简单集群的运行以及一个简单
的运行说明

环境准备

docker-compose 文件

 
version: "3"

services: 

    db:

      image: 1000kit/h2

      container_name: zeebe_db

      ports:

        - "1521:1521"

        - "8181:8181"

    monitor:

      image: camunda/zeebe-simple-monitor

      environment:

        - spring.datasource.url=jdbc:h2:tcp://db:1521/zeebe-monitor;DB_CLOSE_DELAY=-1

        - io.zeebe.monitor.connectionString=broker-1:26500

        - spring.datasource.user=sa

        - spring.datasource.password=

        - spring.jpa.hibernate.ddl-auto=create

        - io.zeebe.monitor.hazelcast.connection=broker-1:5701

      ports:

      - "8080:8080"

    broker-1:

        image: camunda/zeebe:$ZEEBE_VERSION:-latest

        ports:

            - 26500:26500

            - 26501:26501

            - 5701:5701

        environment:

            - ZEEBE_LOG_LEVEL=$ZEEBE_LOG_LEVEL:-debug

            - ZEEBE_NODE_ID=0

            - ZEEBE_PARTITIONS_COUNT=3

            - ZEEBE_CLUSTER_SIZE=3

            - ZEEBE_REPLICATION_FACTOR=3

        volumes:

            - ./zeebe-hazelcast-exporter-0.5.0.jar:/usr/local/zeebe/lib/zeebe-hazelcast-exporter.jar

            - ./broker_1:/usr/local/zeebe/data

            - ./zeebe.cfg.toml:/usr/local/zeebe/conf/zeebe.cfg.toml

    broker-2:

        image: camunda/zeebe:$ZEEBE_VERSION:-latest

        ports:

            - 26510:26500

        environment:

            - ZEEBE_LOG_LEVEL=$ZEEBE_LOG_LEVEL:-debug

            - ZEEBE_NODE_ID=1

            - ZEEBE_PARTITIONS_COUNT=3

            - ZEEBE_CLUSTER_SIZE=3

            - ZEEBE_REPLICATION_FACTOR=3

            - ZEEBE_CONTACT_POINTS=broker-1:26502

        volumes:

            - ./broker_2:/usr/local/zeebe/data

    broker-3:

        image: camunda/zeebe:$ZEEBE_VERSION:-latest

        ports:

            - 26520:26500

        environment:

            - ZEEBE_LOG_LEVEL=$ZEEBE_LOG_LEVEL:-debug

            - ZEEBE_NODE_ID=2

            - ZEEBE_PARTITIONS_COUNT=3

            - ZEEBE_CLUSTER_SIZE=3

            - ZEEBE_REPLICATION_FACTOR=3

            - ZEEBE_CONTACT_POINTS=broker-1:26502

        volumes:

            - ./broker_3:/usr/local/zeebe/data

docker 镜像版本
镜像版本的使用，通过环境变量文件.env ,内容如下：

 

ZEEBE_VERSION=0.20.0

broker exporter 配置
zeebe.cfg.toml 文件

 
[[exporters]]

id = "hazelcast"

className = "io.zeebe.hazelcast.exporter.HazelcastExporter"

?

  [exporters.args]

  # comma separated list of io.zeebe.protocol.record.ValueType

  enabledValueTypes = "JOB,WORKFLOW_INSTANCE,DEPLOYMENT,INCIDENT"

  port = 5701

?

   # If true, the exporter update its position after publish the record to Hazelcast.

   # Otherwise, it never update its position. On broker start, it will always start from the begin of the log.

   # CAUTION! The broker can‘t delete data and may run out of disk space if set to false.

  updatePosition = false

同时需要注意HazelcastExporter 的版本zeebe-hazelcast-exporter-0.5.0.jar

simple-monitor
simple-monitor 是一个简单的UI 操作界面，通过与zeebe gateway 以及HazelcastExporter 通信获取信息
配置通过环境变量

 
      environment:

        - spring.datasource.url=jdbc:h2:tcp://db:1521/zeebe-monitor;DB_CLOSE_DELAY=-1

        - io.zeebe.monitor.connectionString=broker-1:26500

        - spring.datasource.user=sa

        - spring.datasource.password=

        - spring.jpa.hibernate.ddl-auto=create

        - io.zeebe.monitor.hazelcast.connection=broker-1:5701
