使用docker部署es时报错：Invalid initial heap size: -Xms=512m

Question

问题遇到的现象和发生背景

想在centos7环境下使用docker部署es

问题相关代码，请勿粘贴截图

这是我执行的语句：docker run -itd -p 9200:9200 -p 9300:9300 --restart=always --privileged=true --name elasticsearch-server -e "discovery.type=single-node" -e ES_JAVA_OPTS="-Xms=512m -Xms=512m" elasticsearch:latest

运行结果及报错内容

查看docker logs：Exception in thread "main" java.lang.RuntimeException: starting java failed with [1]
output:

error:
OpenJDK 64-Bit Server VM warning: Option UseConcMarkSweepGC was deprecated in version 9.0 and will likely be removed in a future release.
Invalid initial heap size: -Xms=512m
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

我的解答思路和尝试过的方法

我尝试vi /etc/sysctl.conf，添加vm.max_map_count=262144，然后sysctl -p
还尝试降低版本到6.6.2 全都没有起作用

我想要达到的结果

Answer 1

重复了 -Xms=512m -Xmx=512m
