Chainguard Container for aspnet-runtime-fips

Chainguard Containers are regularly-updated, secure-by-default container images.

Download this Container Image

For those with access, this container image is available on cgr.dev:

docker pull cgr.dev/ORGANIZATION/aspnet-runtime-fips:latest

Be sure to replace the ORGANIZATION placeholder with the name used for your organization's private repository within the Chainguard Registry.

FIPS Enablement

Our ASPNET Runtime images have FIPS enabled versions. However, the underlying ASPNET core runtime does not include any mechanisms to enforce FIPS compliance according to Microsoft's official documentation. Accordingly, it is up you and/or your developers to ensure that your application is using FIPS compliant algorithms and that the runtime environment is also properly configured to run in FIPS mode.

Usage

The dotnet-sdk-fips image can be used directly for simple cases, or with a multi-stage build using the dotnet-sdk-fips as the builder and aspnet-runtime-fips as the final target container.

To get started, go to your current dotnet application directory (or where you house your dotnet applications) and execute the following command. This command should be able to detect the dotnet project in your directory and create a base for the docker initialization.

docker init

This command should create the following files.

Dockerfile
compose.yaml
README.Docker.md
.dockerignore

After the files have been created, replace the contents within the created Dockerfile with the following

FROM cgr.dev/chainguard/dotnet-sdk-fips:latest AS build

COPY --chown=nonroot:nonroot . /source

# If your project resides in a sub directory, make sure you are pointing to that directory. ex: If your project resided in a directory called 'app', you would set the destination to /source/app
WORKDIR /source

RUN dotnet publish --use-current-runtime --self-contained false -o Release

# If you are running an .NET project, you can instead pull our .NET image cgr.dev/chainguard/dotnet-runtime-fips:latest
FROM cgr.dev/chainguard/aspnet-runtime-fips:latest AS final
WORKDIR /

# Copy everything needed to run the app from the "build" stage.
COPY --from=build source .

ENTRYPOINT ["dotnet", "Release/dotnet.dll"]

This will build your application using the SDK image and then copy the built application over to the Runtime image which will then start.

You can run and publish a local image with the following command

docker compose up -d --build

You can also remove the container using the following

docker compose down

What are Chainguard Containers?

Chainguard's free tier of Starter container images are built with Wolfi, our minimal Linux undistro.

All other Chainguard Containers are built with Chainguard OS, Chainguard's minimal Linux operating system designed to produce container images that meet the requirements of a more secure software supply chain.

The main features of Chainguard Containers include:

• Minimal design, without unnecessary software bloat
• Daily builds to ensure container images are up-to-date with available security patches
• High quality build-time SBOMs attesting to the provenance of all artifacts within the image
• Verifiable signatures provided by Sigstore
• Reproducible builds with Cosign and apko (read more about reproducibility)

For cases where you need container images with shells and package managers to build or debug, most Chainguard Containers come paired with a development, or -dev, variant.

In all other cases, including Chainguard Containers tagged as :latest or with a specific version number, the container images include only an open-source application and its runtime dependencies. These minimal container images typically do not contain a shell or package manager.

Although the -dev container image variants have similar security features as their more minimal versions, they include additional software that is typically not necessary in production environments. We recommend using multi-stage builds to copy artifacts from the -dev variant into a more minimal production image.

Need additional packages?

To improve security, Chainguard Containers include only essential dependencies. Need more packages? Chainguard customers can use Custom Assembly to add packages, either through the Console, chainctl, or API.

To use Custom Assembly in the Chainguard Console: navigate to the image you'd like to customize in your Organization's list of images, and click on the Customize image button at the top of the page.
