distrobuilder VS LxdMosaic

LXC

which is what docker/podman/containerd use. If you want full system emulation look into LXC/LXD.

LXD is a manager for Linux Containers (LXC), which lets me spin up a kind-of lightweight VM for any distro, instantly. I use it to run proprietary software isolated from the rest of my system (such as Steam); disposable environments for trying stuff out, and running software that doesn't jive well with Nixos.

Check this thread on linuxcontainers LXD forum. Half way down Simos points to the eventual solution:

I found this website https://linuxcontainers.org/ and I am going to test that out for server just to see how it works.

Up to now the best documentation I have come across is the official one at linuxcontainers.org.

Containers, like LXC or Docker.

After five years managing physical servers, then another four years working with VM clusters, the value of Linux Containers(LXC) and their eventual productization as Docker appealed to me.

Docker introduced container images to the technology world, making container images a standardized delivery unit. In fact, before Docker, containerization technology already existed. Let's talk about a more recent technology, LXC (Linux Containers) in 2008. Compared to Docker, LXC is less popular since Docker provides container images, which can be more standardized and more convenient to migrate. Also, Docker created the DockerHub public service, which has become the world's largest container image repository. In addition, containerization technology can also achieve a certain degree of resource isolation, including not only CPU, memory, and other resources isolation, but also network stack isolation, which makes it easier to deploy multiple copies of applications on the same machine.

The Ararat project lacks screenshots or any detail, so I can't quite say what direction it's heading as compared to the other several LXD-specific dashboards/control panels out there (lxdware, LxdMosaic and others).

In that case, let's throw caution to the wind! Ubuntu (debian-based) + lxd (manages lxc containers and qemu VM) + an lxd webUI (https://github.com/turtle0x1/LxdMosaic or https://github.com/lxdware/lxd-dashboard). Unconventional option as lxd usually flies under the radar, but it is a nice alternative to proxmox.

+1, but there are two community webUIs for LXD: https://github.com/lxdware/lxd-dashboard and https://github.com/turtle0x1/LxdMosaic

You won't have a single webUI to manage everything. But LXD has a couple different webUIs to manage those containers and VMs: https://lxdware.com/ and https://github.com/turtle0x1/LxdMosaic

Here two examples. I personally used the first one in the past and it was great. (now I just don't have lxc containers anymore). https://lxdware.com/ https://github.com/turtle0x1/LxdMosaic
