选择安装版本

docker pull elasticsearch:7.3.0

mkdir -p /docker/elasticsearch/config
mkdir -p /docker/elasticsearch/data
mkdir -p /docker/elasticsearch/plugins
echo "http.host: 0.0.0.0" >> /docker/elasticsearch/config/elasticsearch.yml

创建容器并启动

docker run --name es7.3.0 -p 9200:9200 -p 9300:9300  -e "discovery.type=single-node" -e ES_JAVA_OPTS="-Xms64m -Xmx128m" -v /docker/elasticsearch/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml -v /docker/elasticsearch/data:/usr/share/elasticsearch/data -v /docker/elasticsearch/plugins:/usr/share/elasticsearch/plugins -d elasticsearch:7.3.0

-e "discovery.type=single-node" 设置为单节点
特别注意：
-e ES_JAVA_OPTS="-Xms256m -Xmx256m" 
测试环境下，设置ES的初始内存和最大内存，否则导致过大启动不了ES

查看容器

docker ps

启动xpack认证
在配置文件elasticsearch.yml中添加

http.cors.enabled: true
http.cors.allow-origin: "*"
http.cors.allow-headers: Authorization
xpack.security.enabled: true
xpack.security.transport.ssl.enabled: true

进入容器设置认证密码

docker exec -it es7.3.0 bash
elasticsearch-setup-passwords interactive
