--name elasticsearch：将容器命名为 elasticsearch
-p 9200:9200：将容器的9200端口映射到宿主机9200端口
-p 9300:9300：将容器的9300端口映射到宿主机9300端口，目的是集群互相通信
-e "discovery.type=single-node"：单例模式
-e ES_JAVA_OPTS="-Xms64m -Xmx128m"：配置内存大小
-v /kdata/elasticsearch/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml：将配置文件挂载到宿主kdata机
-v /kdata/elasticsearch/data:/usr/share/elasticsearch/data：将数据文件夹挂载到宿主机
-v /kdata/elasticsearch/plugins:/usr/share/elasticsearch/plugins：将插件目录挂载到宿主机(需重启)
-d elasticsearch:7.9.0：后台运行容器，并返回容器ID
--重启后自动启动
docker update elasticsearch --restart=always
