Docker 在应用文件夹中绑定(bind) Elasticsearch 卷

Question

我有以下 docker-compose 文件:

version: "3.3"
services:    
  elasticsearch:
    image: docker.elastic.co/elasticsearch/elasticsearch:6.1.1
    volumes:
      - esdata:/usr/share/elasticsearch/data
    environment:
      - bootstrap.memory_lock=true
      - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
      - discovery.type=single-node
    ports:
      - "9300:9300"
      - "9200:9200"

volumes:
  esdata:

(为了清楚起见，我删除了其他服务)
我可以在/var/lib/docker/volumes/ 中看到卷项目名称 _esdata 但我希望能够在 docker-compose.yml 所在的目录中创建卷，但我没有找到这样做的方法。

灵感来自 How to set a path on host for a named volume in docker-compose.yml ， 我试过

version: "3.3"
services:    
  elasticsearch:
    image: docker.elastic.co/elasticsearch/elasticsearch:6.1.1
    volumes:
      - esdata:/usr/share/elasticsearch/data
    environment:
      - bootstrap.memory_lock=true
      - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
      - discovery.type=single-node
    ports:
      - "9300:9300"
      - "9200:9200"

volumes:
  esdata:
    driver: local
    driver_opts:
      type: 'none'
      o: 'bind'
      device: './' 

但这会引发以下异常:

Caused by: java.nio.file.AccessDeniedException: /usr/share/elasticsearch/data/nodes 

请让我知道我是否应该发布完整的堆栈跟踪或任何其他相关信息。

如果您使用 ./，该卷将安装在同一个文件夹中(我之前通过这样做遇到过权限问题，所以您知道)

version: "3.3"
services:    
  elasticsearch:
    image: docker.elastic.co/elasticsearch/elasticsearch:6.1.1
    volumes:
      - ./esdata:/usr/share/elasticsearch/data
    environment:
      - bootstrap.memory_lock=true
      - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
      - discovery.type=single-node
    ports:
      - "9300:9300"
      - "9200:9200"

volumes:
  esdata:
