I'm using a Dockerfile with .NET 6

# Base image for building the application

FROM mcr.microsoft.com/dotnet/sdk:6.0 AS build-env

# Copy your source code

WORKDIR /app

COPY . .

# Set the working directory

WORKDIR /app/src/BlazorApp

# Publish your application

RUN dotnet publish "BlazorApp.csproj" -c Release -o /app/publish

# Base image for running the application

FROM mcr.microsoft.com/dotnet/aspnet:6.0

WORKDIR /app

# Copy the published output from the build stage

COPY --from=build-env /app/publish .

# Expose your application's port

EXPOSE 80

# Start the application

ENTRYPOINT ["dotnet", "BlazorApp.dll"]

hey thanks for this. Will this work if my github project has the structure:

Client
blazor wasm project
Server
web api
dockerfile
Shared
classlib

Everything including the dockerfile was in a plain .net web api for this to work but i dont know if this will work for hosted .net blazor wasm project given the complex structure.

Hello friend, i can do with this dockerfile, but, you should change the path of .csproj files:

FROM mcr.microsoft.com/dotnet/sdk:8.0 AS build
WORKDIR /app

COPY ["App3/App3.csproj", "App3/"]
RUN dotnet restore "App3/App3.csproj"

COPY . ./
RUN dotnet publish "App3/App3.csproj" -c Release -o /out

FROM nginx:alpine AS final
COPY --from=build /out/wwwroot /usr/share/nginx/html

I also set a variable PORT=80 in my railway service for bind the app port with railway. Work's to me
