如何在 ELK Docker Image 中升级 elasticsearch

Question

我已经使用以下命令在 Linux 服务器上安装了一个 elk docker 镜像：

sudo docker pull sebp/elk

这在堆栈（拉最新版本的麋鹿搬运工图像，这是7.8.0，并且每个服务elasticsearch ， logstash和kibana ）也具有版本7.8.0。

我需要升级elasticsearch到7.9.0出于安全原因。 如何在继续使用sebp/elk映像的同时执行此操作？

Elk 出现包并运行所有 3 个服务并默认链接它们。 使用此设置，您不能仅拆分和升级 elasticsearch。

我建议您使用 docker-compose 独立运行所有三个服务。 使每项服务都可以有您选择的形象。

示例 docker-compose 供您参考：

version: '3.2'

services:
  elasticsearch:
    image: IMAGE_GOES_HERE
    volumes:
      - type: bind
        source: ./elasticsearch/config/elasticsearch.yml
        target: /usr/share/elasticsearch/config/elasticsearch.yml
        read_only: true
      - type: volume
        source: elasticsearch
        target: /usr/share/elasticsearch/data
    ports:
      - "9200:9200"
      - "9300:9300"
    environment:
      ES_JAVA_OPTS: "-Xmx256m -Xms256m"
      ELASTIC_PASSWORD: changeme
      # Use single node discovery in order to disable production mode and avoid bootstrap checks
      # see https://www.elastic.co/guide/en/elasticsearch/reference/current/bootstrap-checks.html
      discovery.type: single-node
    networks:
      - elk

  logstash:
    image: IMAGE_GOES_HERE
    volumes:
      - type: bind
        source: ./logstash/config/logstash.yml
        target: /usr/share/logstash/config/logstash.yml
        read_only: true
      - type: bind
        source: ./logstash/pipeline
        target: /usr/share/logstash/pipeline
        read_only: true
    ports:
      - "5000:5000/tcp"
      - "5000:5000/udp"
      - "9600:9600"
    environment:
      LS_JAVA_OPTS: "-Xmx256m -Xms256m"
    networks:
      - elk
    depends_on:
      - elasticsearch

  kibana:
    image: IMAGE_GOES_HERE
    volumes:
      - type: bind
        source: ./kibana/config/kibana.yml
        target: /usr/share/kibana/config/kibana.yml
        read_only: true
    ports:
      - "5601:5601"
    networks:
      - elk
    depends_on:
      - elasticsearch
