如何在ELK Docker映像中升级Elasticsearch

问题描述

我已使用以下命令在Linux服务器上安装了麋鹿docker映像：

sudo docker pull sebp/elk

这将提取最新版本的麋鹿码头工人镜像，即7.8.0，并且堆栈中的每个服务（elasticsearch，logstash和kibana）的版本也为7.8。 .0。

出于安全原因，我需要将elasticsearch升级到7.9.0。在继续使用sebp/elk码头工人形象的同时如何做？

解决方法

Elk自带软件包，可运行所有3个服务并默认链接它们。使用此设置，您将无法仅拆分和升级elasticsearch。

我建议您使用docker-compose独立运行所有三个服务。这样每个服务都可以有您选择的图像。

示例docker-compose供您参考：

version: '3.2'

  elasticsearch:

        read_only: true
      - type: volume
        source: elasticsearch
        target: /usr/share/elasticsearch/data

      - "9300:9300"
