一、前言
略
二、下载镜像
[root@i-slebi7x6 bin]# docker pull elasticsearch:7.16.3 7.16.3: Pulling from library/elasticsearch ea362f368469: Pull complete 0ccee306c4da: Pull complete 28688537d02c: Pull complete aa5fb23d065d: Pull complete 89f4c512861d: Pull complete bfcc724c6288: Pull complete abb0ba51c947: Pull complete 5f53dd95410f: Pull complete 4b3820751286: Pull complete Digest: sha256:de5474d051409e8222eee30c82ef299f3f3c97bb339bbd19c314178db659f7b4 Status: Downloaded newer image for elasticsearch:7.16.3 docker.io/library/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。
