Deploying a Go app to Fly.io with PB-as-a-framework, and correctly mounting pb_public

[bogdano]

My apologies for opening a separate discussion about this but for the life of me I cannot find a solution and I am pressed for time at this point, I've spent most of my day trying to deploy my app properly.

I don't know how to correctly copy over or mount my pb_public directory-- the docs seem to imply that this is automatic but it isn't working-- my CSS files return a 404 response in JSON. The following is my project structure:

├── tailwind.config.js
├── template
│   └── template.go
└── tmp
    └── build-errors.log

The following is how I set the static dir handler in main.go:

app.OnBeforeServe().Add(func(e *core.ServeEvent) error {
		template.NewTemplateRenderer(e.Router)

		e.Router.GET("/*", apis.StaticDirectoryHandler(os.DirFS("./pb_public"), false))
. . .

And here is my Dockerfile:

ARG GO_VERSION=1
FROM golang:${GO_VERSION}-bookworm as builder

WORKDIR /usr/src/app
COPY go.mod go.sum ./
RUN go mod download && go mod verify
COPY . .
RUN go build -v -o /run-app .

FROM debian:bookworm

COPY --from=builder /run-app /usr/local/bin/
COPY ./pb_public /usr/local/bin/pb_public
CMD ["run-app", "serve", "--http=0.0.0.0:8080"]

I tried sopying over the ./pb_public directory on the penultimate line but that did nothing.

I would really appreciate a little help here.

COPY ./pb_public /pb/pb_public

OMFG I was so close the entire time. Just copy it over to /pb/pb_public/... And then set:

e.Router.GET("/*", apis.StaticDirectoryHandler(os.DirFS("/pb/pb_public"), false))
