Source code compilation

I downloaded chirpstack v4 source code locally and generated the build folder by make build-UI. How does docker use build folder to generate chirpstack image? I didn’t find the UI-related build folder in the chirpstack container

I’m not sure if I understand your question fully, but this is how the build works:

make build-ui

builds the front-end code. This creates a build folder in the ui directory.
Then RustEmbed is used to embed this code into the chirpstack binary:

github.com

chirpstack/chirpstack/blob/master/chirpstack/src/api/mod.rs#L90


      
                      "api_requests_handled_seconds",
                      "Duration of API requests handled by service, method and status code",
                      histogram.clone(),
                  );
                  histogram
              };
          }
          
          
type Error = Box<dyn std::error::Error + Send + Sync + 'static>;
          
          
#[derive(RustEmbed)]
          #[folder = "../ui/build"]
          struct Asset;
          
          
pub async fn setup() -> Result<()> {
              let conf = config::get();
              let addr = conf.api.bind.parse()?;
          
          
    info!(bind = %conf.api.bind, "Setting up API interface");
          
          
    // Taken from the tonic hyper_warp_multiplex example:

This when you compile the chirpstack binary, all the UI files are embedded in the binary
