Ubuntu Chiseled images now contain the Chisel manifest
Ubuntu Chiseled images are a type of distroless container image that contain only the minimal set of packages .NET needs, with everything else removed. New for .NET 10, Ubuntu Chiseled images include the Chisel manifest. The Chisel manifest describes the package contents of the image and can also be used to install additional packages on top of existing Chiseled base images.
Ubuntu Chiseled base images:
