[Feature Request] Support for DASH_HOST / DASH_PORT as environment overrides
还没有人认领这个 Issue。
评估
调研方向
首先检查 pull request #1134 中引入的环境变量处理，并找到 Dash 服务器中现有的 HOST/PORT 支持。完成标准是：设置 DASH_HOST 和 DASH_PORT 时它们具有优先权，同时现有的 HOST 和 PORT 变量继续有效。
由索引模型根据 Issue 内容生成。
描述
Is your feature request related to a problem? Please describe.
I'd like to be able to set DASH_HOST/DASH_PORT as environment variables to exclusively control the listen address for the dash server. HOST/PORT are too generic and collide with other services running on the same environment.
Describe the solution you'd like
Support DASH_HOST and DASH_PORT in addition to HOST and PORT, preferring DASH_HOST/DASH_PORT if they're provided.
Describe alternatives you've considered
I don't see any.
Additional context
From looking at https://github.com/plotly/dash/pull/1134 it seems like the intention was to name this environment variable DASH_HOST, but for some reason it was implemented as just HOST. Not sure if this was a mistake but we probably can't remove support for HOST without a breaking change.
