一、前言

略

二、下载镜像

[root@i-slebi7x6 bin]# docker pull elasticsearch:7.16.3

三、简单部署

首先根据自己的需求修改一下config目录下的jvm.options的JVM配置。

################################################################
##
## JVM configuration
##
################################################################
##
## WARNING: DO NOT EDIT THIS FILE. If you want to override the
## JVM options in this file, or set any additional options, you
## should create one or more files in the jvm.options.d
## directory containing your adjustments.
##
## See https://www.elastic.co/guide/en/elasticsearch/reference/7.16/jvm-options.html
## for more information.
##
################################################################



################################################################
## IMPORTANT: JVM heap size
################################################################
##
## The heap size is automatically configured by Elasticsearch
## based on the available memory in your system and the roles
## each node is configured to fulfill. If specifying heap is
## required, it should be done through a file in jvm.options.d,
## and the min and max should be set to the same value. For
## example, to set the heap to 4 GB, create a new file in the
## jvm.options.d directory containing these lines:
##
## -Xms4g
## -Xmx4g
##
## See https://www.elastic.co/guide/en/elasticsearch/reference/7.16/heap-size.html
## for more information
##
################################################################

-Xms1g
-Xmx1g

如果端口无需修改，则不用配置elasticsearch.yml。可以直接启动即可。

docker run -d --name es2 -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" elasticsearch:7.16.3

三、测试是否启动

在浏览器输入 ip + 端口号。
