Docker部署变量定义

我翻了一下issue和文档，好像没有看到能够在Docker定义environment的地方
在AI方面，openai的Key很长，我想将其定义在Docker的environment中，这样就能够随处开箱即用，目前支持吗？谢谢

Start by reviewing the Docker deployment configuration and existing documentation for environment-variable handling. Determine whether the OpenAI key can already be supplied through Docker environment settings; done means the supported configuration is clearly documented, or the missing support is implemented and verified.
