Docker is the preferred way to host standalone web applications created with the GenHTTP application framework. .NET allows to create images for various platforms and CPU architectures. For a list of available base images, see their Docker Hub page.
To create an image for your web application, create a new file named Dockerfile in the
root directory of your repository. The following example is for an x64 image
running on Linux:
FROM mcr.microsoft.com/dotnet/sdk:8.0-alpine AS build
WORKDIR /source
# copy csproj and restore as distinct layers
COPY Project/*.csproj .
RUN dotnet restore -r linux-musl-x64
# copy and publish app and libraries
COPY Project/ .
RUN dotnet publish -c release -o /app -r linux-musl-x64 --no-restore /p:PublishTrimmed=true /p:TrimMode=Link
# final stage/image
FROM mcr.microsoft.com/dotnet/runtime-deps:8.0-alpine-amd64
WORKDIR /app
COPY --from=build /app .
ENTRYPOINT ["./Project"]
EXPOSE 8080
To build this docker image, run:
sudo docker build -t project -f Dockerfile .
This will create a new image named project. To run a new container
with this image, execute the following command:
sudo docker run -d -p 8080:8080 project
You should now be able to access the application via http://localhost:8080.
