#Apple tries to contain itself with lightweight #Linux #VM for #macOS
Swift-based containerization framework aims to improve performance and security
Based on #OCI images, users can run them in a wide variety of server environments and data centers using orchestration tools like #Kubernetes.
Mac devs already have options for creating #containers, including #Docker, #Podman, Orbstack & Lima. But Docker and Podman, at least in the past, have not performed particularly well.

The Register · Apple tries to contain itself with lightweight Linux VMs for macOSBy Thomas Claburn

I missed this a few days ago:

The FreeBSD containers WG has raised a PR for the OCI container runtime spec to cover FreeBSD/jails-specific features.

This is, roughly speaking, the protocol between things like docker (moby) / containerd / podman and the container runtime (shim) such as ocijail / runj. Once this is approved, it paves the way for exposing the FreeBSD-specific features via the command line in tools like Podman, because they're stable and portable across runtimes.

And the reason I most care about this is that Postgres insists on still using SystemV shared memory (even if you're using mmap, it uses SysV shm for synchronisation), which is not enabled by default for jails. ocijail supports enabling it, but it isn't exposed in the podman command line yet.

This uses FreeBSD jails to implement container isolation.

I don't understand why any software projects that can be fully built from the terminal on a mainstream OS don't provide a reproducible build environment like a Docker image. Why write out documentation for 15 different OSes (that will be outdated in a few weeks anyway) instead of putting that wasted time into developing a reproducible build environment that anyone can just download and start contributing with?

Trump asks people in the US to wait and is ofcourse blaming Biden. I don't think people will believe him. Also the economic downturn is just beginning, in a few days/weeks companies will notice that containers from China are not arriving, more store shelves will be empty, etcetera.
