是否可以将环境变量添加到MongoDB配置文件中？

I am configuring a MongoDB replica set using YAML syntax. However, I'd like to use MONGODB_HOME environment variable to point to the database:

我正在使用YAML语法配置MongoDB副本集。但是,我想使用MONGODB_HOME环境变量指向数据库:

storage:
  dbPath: "ENV['MONGODB_HOME']/data/db"

I've tried using %, $, etc, but without success. Is it possible to do so?

我尝试过使用%,$等,但没有成功。有可能这样做吗?

Just in case, I'm working under Windows 7 64 bit.

为了以防万一,我在Windows 7 64位下工作。

Best regards

The MongoDB config file (as at 3.0) only allows for static configuration values.

MongoDB配置文件(在3.0中)仅允许静态配置值。

If you want to pass dynamic values you could invoke via the command line or a PowerShell script instead, eg:

如果要传递动态值,可以通过命令行或PowerShell脚本调用,例如:

mongod.exe --dbpath %HOME%\data\db

If you're planning on starting up multiple MongoDB server instances (for example, for different users) you'll also want to specify unique --port numbers to listen to.

如果您计划启动多个MongoDB服务器实例(例如,针对不同的用户),您还需要指定要侦听的唯一 - 端口号。

我已经成功设置了一个位置

volumes:
  - mongo:/data/db

As part of a docker-compose.yml, which means I don't have to use the --dbpath CL switch.

作为docker-compose.yml的一部分,这意味着我不必使用--dbpath CL开关。
