Crun Alternatives

crun reviews and mentions

• Show HN: dockerc – Docker image to static executable "compiler"
  12 projects | news.ycombinator.com | 6 Mar 2024

  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.

  On this note, I was really surprised to find Red Hat's OCI runtime is written in C: https://github.com/containers/crun

  Is anyone working on a Rust version?

  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)...

  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
