Docker 装载路径无效：'；['；装载路径必须是绝对路径

我有一个Dockerfile看起来像这样

FROM clkao/postgres-plv8:12-2
VOLUME [ "/cfg" ]
ADD wait-for-env.sh /usr/local/bin
ENTRYPOINT [ "wait-for-env.sh", "/cfg/commondb.env", "docker-entrypoint.sh" ]
CMD ["postgres"]

app/
    /cfg
    /postgres
        Dockerfile
    docker-compose.yml

在我的

docker compose

文件中，我有应用程序的定义

commondb:
restart: "no"
container_name: commondb
build: 
  context: ./postgres
  args: 
    - build_version
    - build_type
image: commonpostgres:$build_version
ports:
  - "5532:5432"
volumes: 
  - /Users/Projects/work/app/cfg:/cfg
networks:
  - common_network

项目布局如下所示

FROM clkao/postgres-plv8:12-2
VOLUME [ "/cfg" ]
ADD wait-for-env.sh /usr/local/bin
ENTRYPOINT [ "wait-for-env.sh", "/cfg/commondb.env", "docker-entrypoint.sh" ]
CMD ["postgres"]

app/
    /cfg
    /postgres
        Dockerfile
    docker-compose.yml

当我尝试运行命令时

docker-compose up -d --no-deps --build commondb

我得到这个错误

invalid mount config for type "volume": invalid mount path: '[' mount path must be absolute

有什么问题

Docker检查包含卷的图像

据猜测，这与Dockerfile中的

VOLUME

语句有关（尽管它在语法上看起来确实有效）。这不是必需的，而且大多数情况下只会产生令人困惑的副作用；删除它会有帮助吗？不，还是相同的问题请在commonpostgres图像上包含

docker inspect

的输出。@BMitch附加了inspectoutput@BMitch我更新了inspect以使用包含卷的映像
