[js-messi]

Hi guys,

Recently I want to remote access slasticsearch,I try to add config on global.sls:

elasticsearch:
config:
xpack:
security:
enabled: falsed
it's not working. and I try to modify slasticsearch.yml in /opt/so/conf/elasticsearch/elasticsearch.yml and restart slasticsearch,it only works a few minutes,then I found the slasticsearch.yml is coverd by default.
I want to know how to modify slasticsearch configuration? Thanks!
