I have made an ASP.NET API with scaffolding. I have generated a docker file in Visual Studio 2019:
#See https://aka.ms/containerfastmode to understand how Visual Studio uses this Dockerfile to build your images for faster debugging.
FROM mcr.microsoft.com/dotnet/aspnet:5.0-buster-slim AS base
WORKDIR /app
EXPOSE 80
FROM mcr.microsoft.com/dotnet/sdk:5.0-buster-slim AS build
WORKDIR /src
COPY ["CoinAPI.csproj", "CoinAPI/"]
RUN dotnet restore "CoinAPI/CoinAPI.csproj"
WORKDIR "/src/CoinAPI"
COPY . .
RUN dotnet build "CoinAPI.csproj" -c Release -o /app/build
FROM build AS publish
RUN dotnet publish "CoinAPI.csproj" -c Release -o /app/publish
FROM base AS final
WORKDIR /app
COPY --from=publish /app/publish .
ENTRYPOINT ["dotnet", "CoinAPI.dll"]
I am building the project with command:
docker build -t coinapi .
And running it with:
docker run -dp 12344:12344 coinapi
The container is running in docker desktop in Windows, but when I access localhost:12344 I get an error 404. After adding this line of code webBuilder.UseUrls("http://localhost:12344"); in Program.cs file, I am getting an ERR_EMPTY_RESPONSE when accessing the URL. What can I do to successfully access my Swagger API run in a docker container?
The thing that did the trick was to change webBuilder.UseUrls("http://localhost:12344"); to webBuilder.UseUrls("http://+:12344"); and now the API works and I can connect to it via the browser with http://localhost:12344/
