云原生KubeSphere部署Elasticsearch

1.1、创建数据目录

        mkdir -p /mydata/es-01

        chmod 777 -R /mydata/es-01

1.2、容器启动脚本

docker run --restart=always -d -p 9200:9200 -p 9300:9300 
-e "discovery.type=single-node" 
-e ES_JAVA_OPTS="-Xms512m -Xmx512m" 
-v es-config:/usr/share/elasticsearch/config 
-v /mydata/es-01/data:/usr/share/elasticsearch/data 
--name es-01 
elasticsearch:7.13.4

/usr/share/elasticsearch/data：将数据文件持久化到pvc

/usr/share/elasticsearch/config: 将这个目录下的elasticsearch.yml文件以及jvm.options文件同步到ConfigMap中

1、开始创建配置

 

点击保存，我们再创建jvm.options:

 

 jvm.options内容如下：

################################################################

## 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/current/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/current/heap-size.html
## for more information

## Expert settings
################################################################
##
## All settings below here are considered expert settings. Do
## not adjust them unless you understand what you are doing. Do
## not edit them in this file; instead, create a new file in the
## jvm.options.d directory containing your adjustments.

## GC configuration
8-13:-XX:+UseConcMarkSweepGC
8-13:-XX:CMSInitiatingOccupancyFraction=75
8-13:-XX:+UseCMSInitiatingOccupancyOnly

## G1GC Configuration
# NOTE: G1 GC is only supported on JDK version 10 or later
# to use G1GC, uncomment the next two lines and update the version on the
# following three lines to your version of the JDK
# 10-13:-XX:-UseConcMarkSweepGC
# 10-13:-XX:-UseCMSInitiatingOccupancyOnly
14-:-XX:+UseG1GC

## JVM temporary directory
-Djava.io.tmpdir=${ES_TMPDIR}

## heap dumps

# generate a heap dump when an allocation from the Java heap fails; heap dumps
# are created in the working directory of the JVM unless an alternative path is
# specified
-XX:+HeapDumpOnOutOfMemoryError

# specify an alternative path for heap dumps; ensure the directory exists and
# has sufficient space
-XX:HeapDumpPath=data

# specify an alternative path for JVM fatal error logs
-XX:ErrorFile=logs/hs_err_pid%p.log

## JDK 8 GC logging
8:-XX:+PrintGCDetails
8:-XX:+PrintGCDateStamps
8:-XX:+PrintTenuringDistribution
8:-XX:+PrintGCApplicationStoppedTime
8:-Xloggc:logs/gc.log
8:-XX:+UseGCLogFileRotation
8:-XX:NumberOfGCLogFiles=32
8:-XX:GCLogFileSize=64m

# JDK 9+ GC logging
9-:-Xlog:gc*,gc+age=trace,safepoint:file=logs/gc.log:utctime,pid,tags:filecount=32,filesize=64m

 配置成功：

 

1、进入创建有状态副本集的路径下

2、开始创建  

限制2核1G的内存：

 

配置环境变量： 

 

点击保存： 

点击下一步：

 

点击保存：

 

 再选择上面的特定路径：

 

点击保存，下面我们在指定jvm.options:

 

 

 点击开始创建：
