Docker中的ApacheNIFI集群超过3个虚拟机'；s

我想在docker中创建一个超过3个虚拟机的NiFi集群。 我发现了一个docker compose文件，它在一个节点上创建了一个集群，并尝试编辑这个文件

我发现我需要zookeeper，但我是否需要每个实例都有一个zookeeper？我应该在docker中打开或映射哪些端口

我找到的docker compose文件：

version: "3"
services:
  zookeeper:
    hostname: zookeeper
    container_name: zookeeper
    image: zookeeper:3.6.1
    environment:
      - ALLOW_ANONYMOUS_LOGIN=yes
  nifi:
    image: apache/nifi:1.11.4
    ports:
      - 8080 # Unsecured HTTP Web Port
    environment:
      - NIFI_WEB_HTTP_PORT=8080
      - NIFI_CLUSTER_IS_NODE=true
      - NIFI_CLUSTER_NODE_PROTOCOL_PORT=8082
      - NIFI_ZK_CONNECT_STRING=zookeeper:2181
      - NIFI_ELECTION_MAX_WAIT=1 min

我这样更改了文件（每个VM上的ip都是正确的）

在日志中我发现了这条消息，但找不到任何解决方案

不，你可以用一个动物园管理员

我应该在docker中打开或映射哪些端口

我知道你需要288838882181才能开门。但只有2181人与nifi通信 2888和3888用于zookeeper群集通信
