Docker-组成卷错误:格式不正确，应为external:internal[:mode]

Question

我有一个docker-compose yml文件，它给了我以下错误：

ERROR: Volume <path>db:/db:rw has incorrect format, should be external:internal[:mode]

我看过很多关于这个问题的帖子，但从来没有一个解决方案。使用以下yml文件处理macOS：

volumes:
  db:
  rdb:

services:
  volumes-provisioner:
    image: hasnat/volumes-provisioner
    environment:
      PROVISION_DIRECTORIES: "1001:1001:0755:/db"
    volumes:
      - "./db:/db:rw"
  volumes-provisioner2:
    image: hasnat/volumes-provisioner
    environment:
      PROVISION_DIRECTORIES: "999:999:0755:/data"
    volumes:
      - "./rdb:/data:rw"
  redis:
    image: "redislabs/redisgraph:2.2.6"
    ports:
      - "6379:6379"
    volumes:
      - "./rdb:/data:rw"
    depends_on:
      - volumes-provisioner2
  insight:
    image: "redislabs/redisinsight:1.7.1"
    depends_on:
      - volumes-provisioner
      - redis
    volumes:
      - "./db:/db:rw"
    ports:
      - "8001:8001"

有什么想法吗？

Answer 1

这可能是你的版本的码头。确保已升级到最新版本，然后在文件顶部添加docker版本声明(版本："3.9")。我已经修改了下面的文件，将其包括在内，我还删除了图像周围的引号。在那之后，它就能工作了。

version: "3.9"

volumes:
  db:
  rdb:

services:
  volumes-provisioner:
    image: hasnat/volumes-provisioner
    environment:
      PROVISION_DIRECTORIES: "1001:1001:0755:/db"
    volumes:
      - "./db:/db:rw"
  volumes-provisioner2:
    image: hasnat/volumes-provisioner
    environment:
      PROVISION_DIRECTORIES: "999:999:0755:/data"
    volumes:
      - "./rdb:/data:rw"
  redis:
    image: redislabs/redisgraph:2.2.6
    ports:
      - "6379:6379"
    volumes:
      - "./rdb:/data:rw"
    depends_on:
      - volumes-provisioner2
  insight:
    image: redislabs/redisinsight:1.7.1
    depends_on:
      - volumes-provisioner
      - redis
    volumes:
      - "./db:/db:rw"
    ports:
      - "8001:8001"

当我从Windows上运行的Windows Subsystem for Linux (WSL)终端运行docker-compose时，我得到了这个错误。如果我从Windows Powershell运行docker-compose，它可以工作。
