排查问题

是说在启动时在解析elasticsearch.yml出现错误，查看自己外部挂载的elasticsearch.yml配置文件（如没有挂载配置文件，则需去容器内查找）

/mydata/elasticsearch/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml \
-v /mydata/elasticsearch/dada:/usr/share/elasticsearch/dada \
-v /mydata/elasticsearch/plugins:/usr/share/elasticsearch/plugins \
-d elasticsearch:7.17.2
