Swagger-Ui file disappears after deploy

[Kimishu]

Hi again!
I've reached some problem when deploying my app on a server. Let's figure it out more clearly:

1. When I tested my app on local machine, despite the different OS, all works fine. My app works clearly on Windows/Linux(WSL), so.. I can easily navigate to https://localhost:8000/swagger-ui.
2. After deploy to a server, my app exists in a docker container. All routes works fine and I even can get an openapi.json by navigating to https://ip:port/api-docs/openapi.json. All works fine except swagger-ui route

I have no idea where problem source is (something goes wrong with deploy or something deleted after build, maybe..?). If someone has any ideas - please, share it with me!
Thanks in advance!

UPD: I found the problem. When app was builded, deploy mechanism get's only binary file main and don't take, as I understand, utoipa files. So, now I should somehow detect what files I need and which not.

So you cannot see Swagger UI after you have build the docker container? utoipa-swagger-ui uses rust-embed to embed the Swagger UI files into the binary. The rust-embed does not embed files on debug build to the binary. Instead you need to either build the project with --release flag or enabled debug-embed feature. https://github.com/juhaku/utoipa?tab=readme-ov-file#swagger-ui-returns-404-notfound-from-built-binary

Here is an example with Docker: https://github.com/juhaku/utoipa/tree/master/examples/axum-utoipa-nesting-vendored

Here you can find the utoipa-swagger-ui feature flags: https://github.com/juhaku/utoipa/tree/master/utoipa-swagger-ui#crate-features
