go build generated prometheus binary doesn't include frontend assets

[Guanpeng Gao]

I use go build under cmd/prometheus to generate prometheus binary

but looks like it doesn't include frontend assets, different from the binary directly build from "make build"

error message: error reading base template: open web/ui/templates/_base.html: no such file or directory

Hi Guanpeng,

Yes, this is intended. The reason is that the new React UI requires some separate build steps that are not Go-based, and the result of that is not checked in (because it's hard to make completely reproducible builds that wouldn't create diffs every time the React UI is built).

See https://github.com/prometheus/prometheus/blob/master/web/ui/react-app/README.md for more details on the React UI build and dev stuff.

Hi Guanpeng,

you can see the steps here in the code: https://github.com/prometheus/prometheus/blob/master/Makefile#L34-L48

The actual building of the app (after modules download etc.) is done in the https://github.com/prometheus/prometheus/blob/master/scripts/build_react_app.sh script referenced from those Makefile steps.
