那么如果是从我Docker入门文章过来的或者是对Docker有个基本了解的小伙伴们现在跟我一起来了解一下在Docker中部署Elasticsearch的步骤吧。

步骤一：下载并运行镜像

PS C:UsersASUS> docker run -d --name es -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" elasticsearch:7.6.2

步骤二：运行测试

访问地址：localhost:9200

在安装和运行的过程中可能有一部分小伙伴的电脑会有点卡顿，这是因为ES非常耗内存，这里我们可以对ES进行一些配置

步骤三[可选]：配置ES的内存限制

加入-e ES_JAVA_OPTS="-Xms64m -Xmx512m"的配置

PS C:UsersASUS> docker run -d --name es -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" -e ES_JAVA_OPTS="-Xms64m -Xmx512m" elasticsearch:7.6.2
