Hosting Apps

Hosting with Docker

Docker is the preferred way to host web applications created with the GenHTTP application framework. .NET 6 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 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
COPY --from=build /app .

ENTRYPOINT ["./Project"]


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.
