Docker-compose 使用弹性搜索的持久卷问题

Question

我在 docker-compose 中为 Elasticsearch 安装卷时遇到问题。该挂载用于另一个磁盘，挂载在：/mt/sda/ 我正在使用以下 docker-compose.yml：

version: "3.0"
services:
  elasticsearch:
    container_name: elastic-container-rescue
    image: docker.elastic.co/elasticsearch/elasticsearch:7.15.0
    volumes:
      - es-data:/mt/sda/es-data
    environment:
      - xpack.security.enabled=true
      - "discovery.type=single-node"
      - "ES_JAVA_OPTS=-Xms1g -Xmx1g"
      - "network.host:0.0.0.0"
      - ELASTIC_PASSWORD=$ES_PASS
      
    ports:
      - 9300:9200
    networks:
      - elastic
networks:
  elastic:
    driver: bridge
volumes:
  es-data:
    driver: local

当我用 docker volume inspect 检查它时，它仍然显示不正确的 mountpoint - 它应该是：/mt/sda/es-data

    {
        "CreatedAt": "2021-11-09T13:51:05+01:00",
        "Driver": "local",
        "Labels": {
            "com.docker.compose.project": "rescue-es",
            "com.docker.compose.version": "1.25.5",
            "com.docker.compose.volume": "es-data"
        },
        "Mountpoint": "/var/lib/docker/volumes/rescue-es_es-data/_data",
        "Name": "rescue-es_es-data",
        "Options": null,
        "Scope": "local"
    }

关于如何分配正确的挂载点有什么建议吗？

具有持久卷配置的 Elasticsearch Docker 容器

docker-compose.yml

version: "3.0"
services:
  elasticsearch:
    container_name: elastic-container-rescue
    image: docker.elastic.co/elasticsearch/elasticsearch:7.15.0
    volumes:
      - es-data:/usr/share/elasticsearch/data
    environment:
      - xpack.security.enabled=true
      - "discovery.type=single-node"
      - "ES_JAVA_OPTS=-Xms1g -Xmx1g"
      - "network.host:0.0.0.0"
      - ELASTIC_PASSWORD=$ES_PASS
      
    ports:
      - 9300:9200
    networks:
      - elastic
networks:
  elastic:
    driver: bridge
volumes:
  es-data:
    driver: local
    driver_opts:
      o: bind
      type: none
      device: /mt/sda/es-data
