新建文件夹

/data/docker/es/plugins
/data/docker/es/data
/data/docker/es/logs

把es的内部文件拷贝出来

docker cp elasticsearch:/usr/share/elasticsearch/plugins /opt/docker/data/es/plugins

docker cp elasticsearch:/usr/share/elasticsearch/data /opt/docker/data/es/data

docker cp elasticsearch:/usr/share/elasticsearch/logs /opt/docker/data/es/logs
