Mastering Docker Image Optimization: 6 Key Strategies for building Lighter, Faster, and Safer images
Dive is an open-source tool that allows you to explore the various layers of a Docker image. It shows you the content of each layer and helps you identify voluminous or unnecessary parts.

I reduced the size of my Docker image by 40% – Dockerizing shell scripts
Dive is a great tool for debugging this. I like image reduction work just because it gives me a chance to play with Dive: https://github.com/wagoodman/dive
One easy low hanging fruit I see a LOT for ballooning image sizes is people including the kitchen sink SDK/CLI for their cloud provider (like AWS or GCP), when they really only need 1/100 of that. The full versions of both of these tools are several hundred mb each

RunCVM: An open-source Docker runtime for launching container images in VMs
Podman supports this since quite a while with the krun variant of the crun runtime (https://github.com/containers/crun/blob/main/krun.1), provided in Fedora by the "crun-krun" package. Just add "--runtime=krun" to your podman command line along the other arguments and you'll get the container running inside a VM powered by libkrun.

Show HN: dockerc – Docker image to static executable "compiler"
Yep pretty much.
The executables bundle crun (a container runtime)[0], and a fuse implementation of squashfs and overlayfs. Appended to that is a squashfs of the image.
At runtime the squashfs and overlayfs are mounted and the container is started.

It's interesting that, in light of things like this, you still see large software companies adding support for new components written in non-memory safe languages (e.g. C)
As an example Red Hat OpenShift added support for crun(https://github.com/containers/crun) this year(https://cloud.redhat.com/blog/whats-new-in-red-hat-openshift...), which is written in C as an alternative to runc, which is written in Go(https://github.com/opencontainers/runc)...

Crun: Fast and lightweight OCI runtime and C library for running containers
Kubernetes needs an OCI runtime to run containers with. Crun is one implementation it can use.
Docker also appears to be able to use crun for it's engine as well. https://github.com/containers/crun/issues/37
