proxmox-lxc-idmapper VS distribution-spec

I found this helpful: https://github.com/ddimick/proxmox-lxc-idmapper

But anyway I found beautiful script to calculate lxc.idmap https://github.com/ddimick/proxmox-lxc-idmapper after i have been brainwashing for hour why the hell VM is not starting and only getting errors from not correct intervals in .idmap.

There is an explanation and some guidance here, but the syntax is a bit difficult and I usually use this tool to help with that. It isn’t perfect but does the job in most situations.

It doesn’t look like it’s being maintained, but I’ve used this helper script with success.

You won't solve by just using the same uids/gids between the container and host, if using an unprivileged container. You'll also need to map the host/container uids/gids to one another. I think I read https://pve.proxmox.com/wiki/Unprivileged_LXC_containers until my eyeballs bled trying to wrap my head around the mapping syntax. https://github.com/ddimick/proxmox-lxc-idmapper might help, too.

Back in 2013, a little company called Docker made it really easy to start using containers to package up applications. A big key to their success was the OCI (you can learn about that here), an industry wide initiative to have standards around how we package up our applications. Because of OCI standards, we have hundreds (maybe thousands?) of tools that can be combined to manage and deploy applications. So why aren’t we using this for packaging up Notebooks and AI models as well? It would make deploying, sharing, and managing our models easier for everyone involved.

Kubernetes on the backend used to utilize docker for much of its container runtime solutions. One of the modular features of Kubernetes is the ability to utilize a Container Runtime Interface or CRI. The problem was that Docker didn't really meet the spec properly and they had to maintain a shim to translate properly. Instead users could utilize the popular containerd or cri-o runtimes. These follow the Open Container Initiative or OCI's guidelines on container formats.

OCI stands for Open Container Initiative, and its goal as an organization is to define a specification for container formats and runtime.

Here is Containerfile from the repo: https://github.com/ublue-os/bazzite/blob/main/Containerfile

apko allows us to build OCI container images from .apk packages.

Flagger's load testing service can be installed via a Kustomization resource based on manifests packaged as an artifact in an Open Container Initiative (OCI) registry

CRI-O is a lightweight container runtime for Kubernetes. It is an implementation of Kubernetes CRI to use Open Container Initiative (OCI) compatible runtimes for running pods. It supports runc and Kata Containers as the container runtimes, but any OCI-compatible runtime can be integrated.

So somebody else created runj (runj is an experimental, proof-of-concept OCI-compatible runtime for FreeBSD jails.) https://github.com/samuelkarp/runj
