docker自定义镜像并使用

写在前面

本文看下如何自定义镜像。

ik包从这里 下载。

1：自定义带有ik的es镜像

先看下目录结构：

/opt/program/mychinese
[root@localhost mychinese]# ll
total 16
-rw-r--r-- 1 root root 1153 Feb  5 04:18 docker-compose.yaml
-rw-rw-r-- 1 elk  elk   291 Feb  5 04:17 Dockerfile
drwxr-xr-x 3 root root  243 Feb  5 03:27 ik710

ik710目录就是ik的解压内容，后续回安装到es，直接拷贝到es的plugins目录就行。

Dockerfile内容：

FROM docker.elastic.co/elasticsearch/elasticsearch:7.1.0
RUN mkdir /usr/share/elasticsearch/plugins/ik710
#RUN cd /usr/share/elasticsearch/plugins/ik710
ADD ik710 /usr/share/elasticsearch/plugins/ik710
# CMD echo "es will start!!!"
# CMD ["/usr/share/elasticsearch/bin/elasticsearch", "-d"]

接着就可以构建镜像了：

docker build -t mychinese:1.2 .

[root@localhost mychinese]# docker images
REPOSITORY                                      TAG                 IMAGE ID            CREATED             SIZE
mychinese                                       1.2                 d0aec608ff4f        12 minutes ago      904 MB
...

接着就可以使用docker-compose 启动了，内容如下：

version: '2.2'
services:
  elasticsearch:
    image: mychinese:1.2
    container_name: es7_011
    environment:
      - cluster.name=geektime
      - node.name=es7_011
      - bootstrap.memory_lock=true
      - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
      - discovery.seed_hosts=es7_011,es7_012
      - cluster.initial_master_nodes=es7_011,es7_012
    ulimits:
      memlock:
        soft: -1
        hard: -1
    volumes:
      - es7data1:/usr/share/elasticsearch/data
    ports:
      - 9220:9200
    networks:
      - es7net
  elasticsearch2:
    image: mychinese:1.2
    container_name: es7_012
    environment:
      - cluster.name=geektime
      - node.name=es7_012
      - bootstrap.memory_lock=true
      - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
      - discovery.seed_hosts=es7_011,es7_012
      - cluster.initial_master_nodes=es7_011,es7_012
    ulimits:
      memlock:
        soft: -1
        hard: -1
    volumes:
      - es7data2:/usr/share/elasticsearch/data
    networks:
      - es7net


volumes:
  es7data1:
    driver: local
  es7data2:
    driver: local

networks:
  es7net:
    driver: bridge

启动：

[root@localhost mychinese]# docker-compose up 
Creating es7_011 ... done
Creating es7_012 ... done
Attaching to es7_012, es7_011
es7_011           | {"type": "server", "timestamp": "2024-02-05T09:32:29,486+0000", "level": "INFO", "component": "o.e.p.PluginsService", "cluster.name": "geektime", "node.name": "es7_011",  "message": "loaded plugin [analysis-ik]"  } # 这里可以看到加载analysis-ik插件了
