如何连接linux主机上的mongodb和码头上的mongo-express

Question

我已经成功地在linux主机上安装了mongodb (redhat 8)。蒙哥什工作得很好，他在27017端口上听讲。我想安装mongod作为码头容器，并将其连接到运行在主机上的mongod(外部码头！)。我已经尝试过以下修理机-Compose.yml：

version: '3.7'

services:

    mongo-express:
        image: mongo-express
        restart: always
       # ports:
       #     - 8081:8081
        environment:
            ME_CONFIG_MONGODB_SERVER: localhost
            ME_CONFIG_MONGODB_ADMINUSERNAME: ${MONGO_USER}
            ME_CONFIG_MONGODB_ADMINPASSWORD: ${MONGO_PASS}
            ME_CONFIG_BASICAUTH_USERNAME: ${MONGO_USER}
            ME_CONFIG_BASICAUTH_PASSWORD: ${MONGO_PASS}
        network_mode: host

我将端口设置注释为与network_mode:host.不兼容。

结果：将构建容器并发出以下警告：

试图访问主机上的mongo速递会给：

[root@d20p280a mongoexpress]# curl localhost:8081
curl: (7) Failed to connect to localhost port 8081: Connection refused

码头ps:

任何提示都很感谢-谢谢！

像往常一样，细节是魔鬼的所在。缺少的线索是错误日志中的这个条目：

mongoexpress-mongo-express-1  | (node:7) UnhandledPromiseRejectionWarning: MongoError: not authorized on config to execute command { listCollections: 1, filter: {}, cursor: {}, nameOnly: false, lsid: { id: UUID("2e2c2b92-4d5d-47d0-9c37-59e52dd3a5df") }, $db: "config" }

The是正确的，如图所示。mongodb中的管理用户只有以下角色："userAdminAnyDatabase", "dbAdminAnyDatabase", "readWriteAnyDatabase"，它缺少listCollections特权。奇怪的是，芒果快车甚至没有启动服务器。我希望网页浏览器中会出现错误信息。感谢所有花时间研究这个问题的人。这是现在使用的管理角色：

roles: [
    {
        role: 'root',
        db: 'admin'
    }
]
