Hazelcast 成员在 2 个不同的 docker 主机中

【问题标题】：Hazelcast members in 2 different docker hostsHazelcast 成员在 2 个不同的 docker 主机中
【发布时间】：2020-09-29 07:02:29
【问题描述】：

该场景由 2 台虚拟机组成，每台虚拟机都有 docker 和 hazelcast 成员作为容器运行。

阅读本指南https://hazelcast.com/blog/configuring-hazelcast-in-non-orchestrated-docker-environments/ 我可以获得场景 3公共 IP 地址、端口映射和 TCP 发现方法，每个节点只有一个成员。 但是，如果我将一个成员添加到其中一个节点，它将取代集群中的另一个成员或记录连接问题。所以我无法让集群在每个节点上使用多个成员。

两个节点中的配置是：

hazelcast:
  network:
    join:
      multicast:
        enabled: false
      tcp-ip:
        enabled: true
        member-list:
          - 10.132.0.2:5701
          - 10.128.0.3:5701
          - 10.128.0.3:5702

节点10.132.0.2 中的容器运行于：

docker run -v `pwd`:/mnt --rm --name member1   -e "JAVA_OPTS=-Dhazelcast.local.
publicAddress=10.132.0.2 -Dhazelcast.config=/mnt/hazelcast.yml"   -p 5701:5701 hazelcast/hazelcast:4.0.1

同一个节点上的成员之间似乎存在通信问题 在另一个测试中，member3 在集群中替换了 member2，并将来自 node2 的连接尝试标记为可疑

虚拟机是在 GCP 上新建的，并且在同一个网络上，我使用了这个图像：

Google, Container-Optimized OS, 85-13310.1041.9 stable, Kernel: ChromiumOS-5.4.49 Kubernetes: 1.18.9 Docker: 19.03.9 Family: cos-stable, supports Shielded VM features, supports Confidential VM features on N2D

【问题讨论】：

    标签： docker hazelcast


    【解决方案1】：

    该问题是由认为在端口 5701 而不是 5702 上的 member3 引起的。 解决方案是在配置中指定成员在docker主机上监听的端口

    member3的配置是

    hazelcast:
  network:
    port:
      port: 5702
    join:
      multicast:
        enabled: false
      tcp-ip:
        enabled: true
        member-list:
          - 10.132.0.2:5701
          - 10.128.0.3:5701
          - 10.128.0.3:5702

    通过这种方式集群工作，每个成员都可以与其他成员通信。

    【讨论】：

    【解决方案2】：

    您的方案应该可行，我想这将是一些环境问题。您可以尝试以下 2 件事吗？

    在 member1 上也显式设置端口

    在 member1 配置中也使用 :5701 - member-list (hazelcast.yml) 和 hazelcast.local.publicAddress 属性（命令行）。

    这一步可能对您的问题没有任何改变，但它至少应该避免日志中出现不相关的警告。

    尝试是否可以从 member3 访问 member2

    启动节点后，在member3 中执行交互式shell 并尝试将协议质询（HZC）发送到member2 的套接字地址。如果您在终端中看到协议响应（HZC），则表明容器之间的通信正常。如果您没有看到响应，请检查您的 Docker 和防火墙配置以查看可能导致问题的原因。

    docker exec -it member3 /bin/bash

# Following command runs in container.
# The first HZC line is the one you type (followed by Enter).
# The second is the reply from member2.

bash-5.0# nc 10.128.0.3 5701
HZC
HZC

    如果您在终端中看到正确的协议响应，我们将需要进一步调查 Hazelcast 行为。我无法在我的环境中重现该问题。

    【讨论】：

    • 我没有回应挑战：$ docker exec -it member3 /bin/bash bash-5.0 # nc 10.128.0.3 5701
    【解决方案3】：

    如果您想更进一步，Hazelcast 支持对容器和来自编排管理器（即 K8s 和 OpenShift）的生命周期调用，为此，您可以使用适用于该特定平台的 hazelcast 网络发现模块。这让您无需对地址和端口进行硬编码，并允许在运行时动态完成这些分配。

    【讨论】：

    • 谢谢，但在这种情况下可以使用哪个发现？我愿意添加容器或简单配置服务以避免写IP和端口
