docker 组合 2 个 qdrant 服务和 1 个卷挂载时被告知不可用

Question

首先是错误日志：

这是我的 docker-compose.yaml：

version: '3.9'
services:
  qdrant_primary:
    image: "qdrant/qdrant:v1.7.3"
    volumes:
      - qdrant_storage:/qdrant/storage
    ports:
      - "6333:6333"
    environment:
      QDRANT__CLUSTER__ENABLED: "true"
    command: ["./qdrant", "--uri", "http://qdrant_primary:6335"]
  qdrant_secondary:
    image: "qdrant/qdrant:v1.7.3"
    volumes:
      - qdrant_storage:/qdrant/storage
    environment:
      QDRANT__CLUSTER__ENABLED: "true"
    command: ["./qdrant", "--bootstrap", "http://qdrant_primary:6335"]
volumes:
  qdrant_storage:
    driver: local
    driver_opts:
      type: none
      o: bind
      device: /Users/test_qdrant

我试图在我的 Mac 上使用 docker-compose 测试 qdrant 的分布式部署，但我的 2 个服务无法同时组成两者。是否因为挂载路径被 qdrant_primary 使用，所以第二个可以访问它？我该如何配置我的 yaml 来处理这种情况？对不起我的 docker 菜鸟

Answer 1

不同的Qdrant实例（节点）必须使用不同的存储目录。您当前正在尝试对多个节点使用相同的存储目录，这就是出现此错误的原因。

保持原始 Docker 撰写文件基本完整，您可能希望将其更改为使用单独的卷，如下所示：

version: '3.9'
services:
  qdrant_primary:
    image: "qdrant/qdrant:v1.7.3"
    volumes:
      - qdrant_storage_primary:/qdrant/storage
    ports:
      - "6333:6333"
    environment:
      QDRANT__CLUSTER__ENABLED: "true"
    command: ["./qdrant", "--uri", "http://qdrant_primary:6335"]
  qdrant_secondary:
    image: "qdrant/qdrant:v1.7.3"
    volumes:
      - qdrant_storage_secondary:/qdrant/storage
    environment:
      QDRANT__CLUSTER__ENABLED: "true"
    command: ["./qdrant", "--bootstrap", "http://qdrant_primary:6335"]
volumes:
  qdrant_storage_primary:
    driver: local
    driver_opts:
      type: none
      o: bind
      device: /Users/test_qdrant_primary
  qdrant_storage_secondary:
    driver: local
    driver_opts:
      type: none
      o: bind
      device: /Users/test_qdrant_secondary

Qdrant 将根据您的使用情况负责跨节点同步您的数据。
