.NET SDK 9.0 container image

Description

.NET is a general purpose development platform. It is cross-platform, and can be used in devices, cloud, and embedded/IoT scenarios. You can use C# or F# to write .NET applications.

This image contains the .NET SDK, consisting of three parts:

• .NET CLI
• .NET Runtime
• ASP.NET Core Runtime

You can use the image to develop, build, and test of .NET and ASP.NET Core applications.

Notice

The .NET packages in the image come from a third-party repository packages.microsoft.com.

The source code is available on github.com/dotnet.

SUSE does not provide any support or warranties for the third-party components in the image.

Usage

To compile an application, copy the sources and build the binary:

FROM registry.suse.com/bci/dotnet-sdk:9.0 AS build
WORKDIR /source

# copy csproj and restore as distinct layers
COPY *.csproj .
RUN dotnet restore

# copy and publish app and libraries
COPY . .
RUN dotnet publish --no-restore -o /app

# final image
FROM registry.suse.com/bci/dotnet-runtime:9.0
WORKDIR /app
COPY --from=build /app .

# uncomment to run as non-root user
# USER $APP_UID

ENTRYPOINT ["./dotnetapp"]

Build and run the container image:

podmanbuild -t my-dotnet-app .
podman run -it --rm my-dotnet-app

There are situations, where you don't want to run an application inside a container.

To compile the application without running it inside a container, use the following command:

podman run --rm -v "$PWD":/app:Z -w /app registry.suse.com/bci/dotnet-sdk:9.0 dotnet run

To run unit tests in an isolated environment, use the following command:

podman run --rm -v "$PWD":/app:Z -w /app/tests registry.suse.com/bci/dotnet-sdk:9.0 dotnet test --logger:trx

Globalization

.NET includes globalization capabilities, including support for processing natural language text, calendars, currency, and timezones. The .NET implementation for these capabilities is based on system libraries available in the container image, such as International Components for Unicode (ICU) and tzdata.

It's considered a good practice to pass timezone information into a container via environment variable TZ.

podman run --rm -it -e TZ="Europe/Berlin" app
