mongodb docker容器启动失败并显示以下错误：IllegalOperation：试图在只读目录/ data / db上创建锁定文件，终止

我使用正式的mongodb Dockerfile来构建容器，并使用docker-compose来启动它。

这是我的Dockerfile：

FROM ubuntu:bionic

# add our user and group first to make sure their IDs get assigned consistently, regardless of whatever dependencies get added
RUN groupadd -r mongodb && useradd -r -g mongodb mongodb

VOLUME /data/db /data/configdb

COPY docker-entrypoint.sh /usr/local/bin/
ENTRYPOINT ["docker-entrypoint.sh"]

EXPOSE 27017
CMD ["mongod"]

和docker-compose如下：

  mongodb:
    build: ./dockerfiles/mongodb
    volumes:
      - ./data/mongodb/db:/data/db
      - ./data/mongodb/configdb:/data/configdb
    ports:
      - 7017:27017
    environment:
      - MONGO_INITDB_ROOT_USERNAME=super
      - MONGO_INITDB_ROOT_PASSWORD=123456
    restart: always

我希望容器成功启动。但是我遇到了：IllegalOperation失败：试图在只读目录/ data / db上创建锁定文件，终止

如果我删除卷部分，则可以！主机是ubuntu18.04，/ data是可写的！

我已经解决了我的问题，老铁！

我使用vmware启动Ubuntu服务器，并与Windows 7共享一个文件夹。共享文件夹上的容器卷。

检查mongodb容器的检查信息。

 "Mounts": [
        {
            "Type": "bind",
            "Source": "/mnt/hgfs/ubuntu/dockers/data/mongodb/configdb",
            "Destination": "/data/configdb",
            "Mode": "rw",
            "RW": true,
            "Propagation": "rprivate"
        },
        {
            "Type": "bind",
            "Source": "/mnt/hgfs/ubuntu/dockers/data/mongodb/db",
            "Destination": "/data/db",
            "Mode": "rw",
            "RW": true,
            "Propagation": "rprivate"
        }
    ],

源包含字符串“ / mnt / hgfs / ubuntu”告诉我们：它是共享文件夹！
