.NET 8 samples size report

[richlander]

We're working on a samples update for .NET 8 at #4742. This is a separate issue to track size. It's pretty interesting. I wrote a tool that builds all the Dockerfiles in a directory (using the Dockerfile name as the tag name) making it straightforward to identify which image is which.

dockerfile is always Debian and .chiseled is Ubuntu Chiseled (distroless). All other tags should be self-descriptive. If not, please ask.

#4759 is a .NET 7 baseline size report.

Both x64 and Arm64 reports are provided. These chip types support different ISAs (naturally) and the amount of code needed is not the same (which directly contributes to size). Arm64 biases to bigger.

Delete the images

Off topic, but here's how I delete these images.

docker rmi -f $(docker images --filter="reference=dockerfile*" -q)

@richlander - to clarify these are the .NET 8.0 samples I assume since there are composite images? It would be interesting to see the size of the current samples based on .NET 7.0 (outside of the composite images which don't exist in 7.0).
