本文介绍了两种在Docker中部署Elasticsearch的方法，包括快速部署和生产环境配置。快速部署中，所有用户密码相同，适合测试验证；生产部署涉及更多安全设置，如内存分配、远程访问配置，并使用docker-compose.yml文件进行容器管理。通过配置文件elasticsearch.yml和jvm.options调整集群名称、网络设置、JVM参数等，确保服务稳定运行。启动和访问Elasticsearch时，还需设置密码并关注权限问题。

镜像下载：

docker pull m.daocloud.io/docker.io/elastic/elasticsearch:8.15.0

方式1：

# 1.创建es 相关挂载目录
mkdir -p /home/mqq/elasticsearch/elasticsearch_docker_map_path/config/
mkdir -p /home/mqq/elasticsearch/elasticsearch_docker_map_path/data
mkdir -p /home/mqq/elasticsearch/elasticsearch_docker_map_path/plugins
# 2. /home/mqq/elasticsearch/elasticsearch_docker_map_path/config/ 下创建文件
vim elasticsearch.yml
cluster.name: "docker-cluster"
network.host: 0.0.0.0
# 允许远程访问
http.host: 0.0.0.0
http.cors.enabled: true
http.cors.allow-origin: "*"
http.cors.allow-headers: Authorization
xpack.security.enabled: true

vim jvm.options

-Xms16g
-Xmx16g

-XX:+UseG1GC

## JVM temporary directory
-Djava.io.tmpdir=${ES_TMPDIR}

20-:--add-modules=jdk.incubator.vector

-XX:+HeapDumpOnOutOfMemoryError

-XX:+ExitOnOutOfMemoryError

-XX:HeapDumpPath=data

-XX:ErrorFile=logs/hs_err_pid%p.log

-Xlog:gc*,gc+age=trace,safepoint:file=logs/gc.log:utctime,level,pid,tags:filecount=32,filesize=64m

# 3. 设置目录权限，否则会报错
chmod +x elasticsearch.yml
# 设置为目录 777 权限
chmod -R 777 /mydata/elasticsearch

docker run -d --name elasticsearch85 -p 0.0.0.0:9702:9200 -p 0.0.0.0:9703:9300 -v /home/mqq/elasticsearch/elasticsearch_docker_map_path/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml -v /home/mqq/elasticsearch/elasticsearch_docker_map_path/data:/usr/share/elasticsearch/data -v /home/mqq/elasticsearch/elasticsearch_docker_map_path/plugins:/usr/share/elasticsearch/plugins -e "discovery.type=single-node" -e "xpack.security.enabled=true" -e "ELASTIC_PASSWORD=yourpasswd" --restart=unless-stopped docker.elastic.co/elasticsearch/elasticsearch:8.5.1

这种方式生成的所有用户密码都一样，适用于快速部署测试验证。

方式2：生产部署

前期准备：

# 1.创建es 相关挂载目录
mkdir -p /home/mqq/elasticsearch/elasticsearch_docker_map_path/config/
mkdir -p /home/mqq/elasticsearch/elasticsearch_docker_map_path/data
mkdir -p /home/mqq/elasticsearch/elasticsearch_docker_map_path/plugins
chmod -R 777 /home/mqq/elasticsearch/
# 2. /home/mqq/elasticsearch/elasticsearch_docker_map_path/config/ 下创建文件
vim elasticsearch.yml

cluster.name: "docker-cluster"
network.host: 0.0.0.0
# 允许远程访问
http.host: 0.0.0.0
http.cors.enabled: true
http.cors.allow-origin: "*"
http.cors.allow-headers: Authorization
xpack.security.enabled: true

# 3. 设置目录权限，否则会报错
chmod +x elasticsearch.yml
# 设置为目录 777 权限
chmod -R 777 /mydata/elasticsearch

对应的docker_compose.yml文件配置如下：

version: "3"

networks:
elasticsearch8:
external: false
services:
elasticsearch:
image: elasticsearch:8.5.1
container_name: elasticsearch851
environment:
- discovery.type=single-node
- ES_JAVA_OPTS=-Xms1024m -Xmx1024m
ports:
- 9201:9200
- 9301:9300
networks:
- elasticsearch8
volumes:
- /home/mqq/elasticsearch/elasticsearch_docker_map_path/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml
- /home/mqq/elasticsearch/elasticsearch_docker_map_path/data:/usr/share/elasticsearch/data
- /home/mqq/elasticsearch/elasticsearch_docker_map_path/plugins:/usr/share/elasticsearch/plugins
