我在Docker中遇到Elasticsearch 5的问题。

堆栈撰写文件：

version: "3.4"

    elastic01: &elasticbase

    elastic03:

            - elastic01
        volumes:

        environment:

        deploy:
            placement:
                constraints: [node.hostname == node3]       

    networks:
        default:
            driver: overlay
            attachable: true

当我运行堆栈文件时，它就像一个魅力。 _cluster / health显示节点已启动并运行状态为＆＃34;绿色＆＃34;但是在一段时间之后，系统会定期出现异常弹性异常

奇怪的是，它始终发生我能够ping容器并从容器中解析名称。没有丢包，没有超时。唯一不好的是Elastic中的传输层。所有其他服务都在同一个集群中运行而没有问题（MongoDB，Redis，内部微服务）

有人有线索吗？

1 个答案:

答案 0 :(得分：0)

我发现了这个问题。

Elasticsearch必须绑定到单个接口，而不是0.0.0.0。一旦我将它绑定到eth0，它就开始工作了。此外，它看起来，没有命名的卷 - 它在此期间抛出另一个错误。它必须直接安装在本地驱动器上。

这有效：

services:
    elastic01:
        environment:
            network.host=_eth0_
